What would a chemist use to measure exactly 25.5 cm^3 of dilute hydrochloric acid? A) Burette, B) Beaker, C) Measuring cylinder, or D) Pipette?

The beaker would not be good because it is hard to measure
accurately to a millimeter.  Pipettes generally are used to dispense liquids by the drop
and not for actually measuring the volume of a liquid.

Both
measuring cylinders (also called graduated cylinders) and burettes can be used to
measure volume.  With a graduated cylinder you add the liquid to the cylinder and read
the volume on the gradation lines etched into the side of the cylinder. Depending on the
cylinder you could accurately measure your volume this
way.

If you want to accurately measure the volume of a
liquid you are putting into another container, then the burette would be the best
choice.  Burettes are used, for example, to do acid-base titrations, and can measure the
volume of liquid released with great precision.

The
advantage with the burette is that you put the liquid into the burette, measure its
initial volume, and then dispense the liquid to get an exact amount.  If you put exactly
25.5 ml in a graduated cylinder and then transfer it to another container some of the
liquid will remain in the cylinder due to surface tension so you will not have the exact
amount you started with.

Overall, the burette will give you
the most exact measurement of any volume you want.

What happens when a currency is devalued?

The devaluation of currency can only happen when a nation
has been keeping its currency at a fixed exchange rate.  For example, if Mexico keeps
its peso at, for example, 15 pesos to the dollar, that is a fixed exchange rate.  In
such a case, a government can devalue its currency by changing the rate and making its
money worth less.  In this example, the Mexican government could change the exchange
rate and say that the peso is now worth less -- 30 pesos to the
dollar.

One major impact of such a move is that the
country's exports become cheaper for people in other countries to buy.  This is often
seen as a reason to devalue -- to allow your country's exporters to sell more goods
abroad.

There are many other impacts, though, and not all
of them are good.  For example, devaluation can result in a huge loss of confidence
among the citizens of the country that devalues its currency.  Please follow the link
for a thorough discussion of various impacts of devaluation.

When did they buy their last tv wall?

When you say "they" I assume that you are talking about
Guy and Millie Montag.  If so, they bought their last TV wall not very long ago at all. 
Specifically, they bought it only two months before the time that this conversation is
happening.

This is important because it shows how
materialistic Millie is and how she is never satisfied with what she has.  This is just
how their society wants people to be.  She has gotten her third wall (at huge expense)
just two months before and she is already bored with it and wants another one.  She
thinks that will make her happy, but it's pretty clear that nothing can truly make her
happy because her life is empty.

Use the first principle to determine the derivative of the function. f(x) = 5x^3 + 3x^2 - 2x + 15

According to the first principle of derivation, the
derivative of f(x) or f'(x)=
lim(h->0){[f(x+h)-f(x)]/h}

Here
f(x)=5x^3+3x^2-2x+15

f(x+h)=5(x+h)^3+3(x+h)^2-2(x+h)+15

=5*x^3+5*h^3+15*x^2*h+15*x*h^2+3*x^2+3*h^2+6*x*h-2x-2h+15

f(x+h)-f(x)=5*x^3+5h^3+15x^2*h+15x*h^2+3x^2+3h^2+6xh-2x-2h+15-5x^3+3x^2-2x+15

=5h^3+15x^2h+15xh^2+3h^2+6xh-2h

[f(x+h)-f(x)]/h=(5h^3+15x^2*h+15x*h^2+3h^2+6xh-2h)/h

=5h^2+15x^2+15xh+3h+6x-2

lim(h->0)[5h^2+15x^2+15xh+3h+6x-2]

=15x^2+6x-2

Therefore
(5x^3+3x^2-2x+15)' by the first principle is
15x^2+6x-2.

What is Lady Macbeth's role in Macbeth?

Lady Macbeth could also be considered to be the antagonist
or villain of the play, which means that she is operating in opposition to Macbeth, or
against his best interests.  Shakespeare makes it pretty clear in her speech in Act One,
scene five, that she considers Macbeth too kind-hearted to do what must be done for him
to become king.  She then calls on the agents of darkness (evil).  She
incants:

readability="13">

...fill me from the crown to the toe
top-full

Of direst cruelty!  Make thick my
blood,

Stop up the access and passage to
remorse,

That no compunctious visitings of
nature

Shake my fell
purpose.

She has just, in
effect, created a pact with the devil, and certainly in the crucial early scenes, as
Macbeth is choosing his course of action, her instigation is a key motivation to his
choices.  So, Lady Macbeth can be seen to be the antagonist and evil influence that
prompts Macbeth towards his tragic course of action.

If the littluns retold the events that happened on the island, how would their experiences differ from the point of view of the older boys?I know...

Good question.

The littluns
are not major characters in the novel as a whole and do not have a massive part to play
in the development of the story. But Golding does very cleverly make their story clear
as a subplot to the main events with the older boys.

They
are often a barometer for how the boys as a whole are
feeling:

Have
you been awake at night?' Jack shook his head.

'They talk and scream.
The littluns. Even some of the others. As if-'

'As if it wasn't a good
island.'

The terror of the
littluns is only heightened later at the meeting when first Ralph and then Jack entirely
fail to crush the silly rumours of the idea of a monster. Jack, in particular, has
absolutely no sympathy for them at all:

readability="8">

'So this is a meeting to find out what's what.
I'll tell you what's what. You littluns started all this with the fear talk. Beasts!
Where from? Of course we're frightened sometimes but we put up with being frightened...
Anyway, you don't hunt or build or help-you're a lot of cry-babies and
sissies.

Neither Ralph nor
Jack seems to know how to appeal to the littler boys, and it is only Piggy (who, of
course, takes responsibilty right at the start for getting all of their names down) and
Simon (I'll come back to him in a second) who know how to ease their fear and make them
feel better. This meeting, though, ends in the littluns screaming with
terror:

readability="8">

....the littluns were no longer silent. They were
reminded of their personal sorrows; and perhaps felt them¬selves to share in a sorrow
that was universal. They began to cry in sympathy, two of them almost as loud as
Percival.

At the end of the
chapter, too, Golding closes ominously on the wailing from the utterly terrified
Percival:

A
thin wail out of the darkness chilled them and set them grabbing for each other. Then
the wail rose, remote and unearthly, and turned to an inarticulate gibbering. Percival
Wemys Madison, of the Vicarage, Harcourt St. Anthony, lying in the long grass, was
living through circumstances in which the incantation of his address was powerless to
help him.

It is an incredibly
sympathetic picture: these are very small boys ("tiny tots", as they are seen at the end
by the Naval Officer) away from home, and entirely without comfort. And the blame for
that has to lie at the feet of the older boys - except perhaps Piggy and certainly
Simon.

Simon, in line with the Jesus-like role he plays in
the novel, helps out those less fortunate for him, at one point actually passing fruit
to the littluns, who by later in the novel appear to have been forgotten about
altogether:

readability="10">

Simon found for them the fruit they could not
reach, pulled off the choicest from up in the foliage, passed them back down to the
endless, outstretched hands. When he had satisfied them he paused and looked round. The
littluns watched him inscrutably over double handfuls of ripe
fruit.

So if you're writing
this essay, focus on the early death of the birthmark boy and the rise of the littluns
terror. Say some positive things about Simon. But the truth of the matter is - and this
is a good point in itself - the bigger boys, by the end of the novel, hardly take the
littluns into account at all. We don't even hear how they are managing (or not) to
survive.

PLease can you help me with a powerful last sentence for my essay on: Tell us what you do for pleasure in your busy life. We know you lead a busy...

What an excellent essay. It does have a few grammatical
errors in it to correct before turning it in. Here are some of my
thoughts:

In the daily grind of simply living through
another twenty-four hours, this simple magic can cure the ills of the individual's
personal world.

Without these brief, magical interruptions
to our daily existence, life would hold much less
meaning.

This time to laugh, ponder, and thrill to an
unknown world can vastly improve our own small
universe.

Without this magic to draw us from our shells, we
would, indeed, be a dull folk.

I hope some of these will
spark your own unique ending for your own, unique essay. I so agree with it. While
studying for orals for my master's degree, I took time out to see an obscure movie
called Great Scout and Cathouse Thursday ( I think that's the
correct day of the week) with Lee Marvin. I laughed so hard, it cleared my cluttered
mind to cram a little more in. And, yes, I did pass my orals!

In the story, who can be considered the "good guys" and the "bad guys?"

I think that the greatness of the story is that it really
does not include the idea of "good" and "bad" guys.  There are human beings who are
capable of some fairly dark and intense elements if the conditions are right.  The
doctor is not a bad guy, in the broadest sense of the term. He comes there to help the
girl, to protect others from infection, and to solve a medical problem.  The parents are
not bad, on the whole.  They want their child to be healed.  The girl is not bad, but
rather wanting to conceal the fact that she is sick.  They are not bad people, but in
the alignment of circumstances and conditions, their dark sides are revealed.  The
parents are shown to be ineffective, at best.  The girl is revealed to be an intensely
driven and angry child.  The doctor's sadistic element is illuminated.  In the story,
there are not "bad" or "good" guys, but there is the capacity for some unsightly
elements to human nature that can be revealed under the right circumstances.  The will
to act is something that helps to bring about elements within human nature that are not
necessarily representative of the "better angels of our nature."   In this, Williams
constructs a story where terms such as "good" and "bad" become contextual, indicating
that human nature is complex and labels are not entirely
effective.

Whats the balanced equation for Ba(OH)2 and FeSO4?which of the products are aqeous

Ferrous hydroxide, Ferric hydroxide and Barium sulfate are
insoluble or in other words they are not aqueous.

Ba(OH)2
is soluble and exists as Ba(2+) and 2 OH- ions. Ferrous sulfate reacts with the OH- ion
and gives Ferrous hydroxide and a SO4(2-) ion. So if Ba(OH)2 and FeSO4 are mixed, the
FeSO4 will react with the OH- ions to give Fe(OH)2, which is insoluble and a SO4(2-) ion
that has to be accepted by the Ba(2+) ions resulting in Barium sulfate which is also
insoluble.

I am not sure the two chemicals will react but
if they do, both the resulting compounds of the reaction will be
precipitated.

If a reaction does take place between the
two, the balanced equation would
be:

Ba(OH)2+FeSO4=BaSO4+Fe(OH)2

Why does food have to be cooked if it can be eaten raw?

Many food products do not have to be cooked before being
eaten. Most (if not all) vegetables and fruits can be eaten raw, and many people prefer
them in this state. Most seafood can also be eaten raw, and beef can be eaten raw if
prepared properly. It is not advisable to eat most other forms of animal flesh uncooked,
however. Bacteria, such as Escherichia coli (E-coli), is present in most meats, and it
can cause sickness and even death. It is preferable to cook pork, poultry, lamb and wild
game. Heat destroys the bacteria present. And, as most people know, cooking meat
generally makes it taste better.

How can I make a cultural reference to Hamlet's speech "What a piece of work is man"?I'm having a socratic seminar tomorrow and this is the only...

A cultural reference is when an older, classical work is
referred to in a later work of art or popular culture.  In the case of Hamlet's speech,
"What a piece of work is man," there are many references to it in later
works.

In the 1960's rock musical "Hair," Hamlet's speech
is quoted word-for-word in a song called (what else?) "What a piece of work is man." 
(See the second link below.)

In a "Star Trek" episode, a
character says:

What Hamlet said with irony I say with
conviction:  

readability="10">

‘What a piece of work is man! How noble in
reason, how infinite in faculties, in form and moving how express and admirable, in
action how like an angel, in apprehension how like a
god!’

 

In other words, Hamlet
is not really sure how great "a piece of work is man," because he is so confused and
depressed; the speaker in Star Trek, however, is convinced that man really is a great
"piece of work."

See the first link below for
more on this and other cultural references to Hamlet's speech. 

It’s a month later and the Youngers are settling in to their new house, what happens? -Write what happens to each character. -Give what you...

A month seems like a rather short time to assess much of
anything, but I get the basic idea.  I think that much of this depends on whether or not
you believed in the narratives of success that accompanied many of the challenges
African- Americans faced in the 1960s and 1970s.  If one believed the narratives of
those who did "make it," then I think the Younger family has found a great deal of
contentment and relief in their decision.  They assimilated well into Clybourne Park,
with struggle still present, but the overall success of the family was one where success
is evident in the decision that Walter undertook.  Beneatha has probably found some
level of stability in her life as she has understood that freedom is more effective when
it is channeled into one path and the multiplicity of avenues within it.  Travis has
experienced better schooling in Clybourne Park.  Walter has been able to build upon the
decision he made and act in the name of the family, while Mama has been able to take
some solace in what she has done and how she has provided for her family's future.  The
plant received its share of water and is growing quite nicely for while there is
struggle to grow in harsh conditions, it is in fact for the reason for struggle and
growth was indeed evident.

On the other side of the coin
would be the narratives of those who did not make it.  These are the individuals who
discovered, as in the title of the book, that there "Ain't No Makin' It."  These are
individuals who bought into the opportunity ideology, like the Youngers, and believed in
the idea of upward mobility. They believed that if they did what was told to them as
tenets of the American Dream, success will be theirs.  Yet, for these narratives, there
was inertia, embedded resistance, that precluded them from fully being able to partake
what should have been rightfully theirs.  These voices faced many oppositions, such as
outward hostility in the likes of Clybourne Park.  They faced silent contempt and
outward intimidation with moving into "White" neighborhoods.  They experienced
discomfort in acting upon their freedom and their entrance into schools populated by
White children and staffed with White adults was one where challenge was evident.  For
these individuals, there was struggle and battle all throughout their moves to areas
where they were the only face of color on the block.  There was intense wondering if all
of this was actually worth it and after such reflection, there might have been a feeling
of surrendering the fight.  For many of these, a feeling of melancholy set in and the
basic idea of not being able to succeed settled in, causing them to languish in a world
where they and others have discounted their efforts into a growing underclass of
individuals.  This might not have happened to the Youngers, but an argument can be made
that many like them experienced the same set of experiences.

Is it possible for a pregnancy to go full term in an ectopic pregnancy?

An ectopic pregnancy is when a fertilized egg is implanted
in some anatomical structure other than the uterus. They are called extrauterine
pregnancies. Commonly, the egg will be located in one of the fallopian tubes, this is
called a tubal pregnancy. This usually happens shortly after fertilization but symptoms
are not evident until between the 6th and 12th week after the egg has been fertilized.
The woman will "feel pregnant" and she will have a positive pregnancy
test.

Extrauterine pregnancies do not continue to term
because when the gamete starts to grow and gets larger in size, the anatomical location
can't accommodate the growth. If the location is in the fallopian tube, the increasing
size of the gamete stretches the tube and causes increased luminal pressure, this
results in abdominal pain for the mother and eventually the fallopian tube will rupture,
this terminates the pregnancy.

These events can lead to
massive intraabdominal hemorrhage and hypovolemic shock. Emergent surgical intervention
is needed.

solve for x and y: 2x-y = 5 x+y = 3

We'll solve the system of
equations:

 2x-y = 5 
(1)

x+y = 3 (2)

We'll solve
the system using the substitution method.

We'll subtract y
both sides, in the second equation:

x =
3-y

We'll subtract 3 both
sides:

x-3 = -y (3)

We'll
substitute (3) in (1):

 2x-y =
5

2x + x - 3 = 5

We'll combine
like terms:

3x - 3 = 5

We'll
add 3 both sides:

3x = 5+3

3x
= 8

We'll divide by 3 both
sides:

x =
8/3

We'll substitute x in (3), to find out
the value of y:

x-3 = -y

8/3 -
3 = -y

We'll multiply -3 by
3:

(8-9)/3 = -y

-1/3 =
-y

We'll multiply by -1 both
sides:

y =
1/3

The solution of the system
of equations is {(8/3 , 1/3)}.

In "A Raisin In The Sun" Act 1 Scene 1 - Why did Walter ask Ruth what was wrong with her? (short answers)

Simply put, Walter does not know about Ruth's condition. 
The audience doesn't know until later, but Ruth is carrying the emotional and physical
weight of a pregnancy.  This is part of the reason why Walter asks what is wrong with
her. The other part of this is that there is the obvious tension in the opening of the
play regarding the arrival of the insurance check.  This causes a noticeable tension in
the air around the Younger home.  The fact that Walter is asking Ruth what is wrong with
her might also be reflective of Walter's own anxious state where he is more worried than
anyone else about that check because he has more riding on it than anyone else in terms
of his own hopes and dreams.

Where do they end up finding Richard Parker in Life of Pi?

Richard Parker is actually a 450 pound, male Bengal tiger
who escaped the sinking of the ship. Pi helped the tiger climb on board the lifeboat,
knowing that man and tiger won't necessarily co-exist. When Pi's lifeboat finally
drifted across the Pacific and grounded itself on the Mexican shores, Richard Parker
jumped from the boat and scampered off into the jungle without so much as looking back.
There he could find the food and water he desperately needs to survive. At the end of
the story, no trace of Richard Parker was ever found. The reader is left to ponder which
story Pi told was the real one.

In the book, The Cay, what kind of job did Phillip's dad have and where did he and the family sleep?Summary of first three chapters.

Phillip's father, Phillip Enright Sr., works for the Royal
Dutch Shell Oil refinery in Willemstad, Curacao, specializing in the production of
aviation gasoline. He had earlier worked in America (probably Virginia) before being
"borrowed" to work in the West Indies.

Phillip normally
sleeps on the second floor of the family's "gabled green house" in Willemstad, but
during the blackout, he slept downstairs on the couch for safety purposes. Phillip's
mother, Grace, and father also usually sleep in the upstairs bedroom, but her husband
also told her to sleep downstairs, probably on the floor or a second
couch.

Who is the main charcter in A Northern Light?

Mattie Gokey is the narrator and protagonist of
A Northern Light.  She is sixteen when the novel opens, and she is
conflicted by life decisions that she has to make.  She has the option of marrying Royal
Loomis and settling for a safe, conventional life; however, Mattie dreams of going to
college and becoming a writer.  Her parents do not agree, and this causes problems for
Mattie, especially because her mother is sick and dying.  Mattie decides to pursue her
dreams of college and begins working with her friends at the Glenmore Hotel to make
money for her tuition.  While at the hotel, Mattie learns of the death of Grace Brown
and finds Grace's letters to her lover.  Mattie becomes very involved in Grace's life
and tries to piece together the clues surrounding her drowning.

Arrange the numbers increasingly: cos 3, cos 2, cos 1.

First, we'll establish the quadrants that contain the
values,1 , 2, 3.

The first quadrant: (0 ;pi/2), where pi =
3.14, so pi/2 = 1.57

The second quadrant: (pi/2 ;pi)
=> (1.57;3.14)

It is obvious that 1 is in
the interval (0,pi/2), meaning the first quadrant, where the function cosine is
positive,then cos 1>0.

Because 2 and 3 are in the
set (pi/2,pi), then cos2 and cos 3 are negative, because they belong to the second
quadrant, where the values of cosine function are
negative.

So the biggest element is cos
1.

The numbers are arranged in
this way: cos 3, cos 2, cos 1.

Implementing strategies effectively is of great importance.The success of strategy depends on how effectively it is implemented.Elucidate.

Goals, objectives and
targets

Strategic planning is a very important title="Business">business activity. It is also important in the title="Public sector">public sector areas such as title="Education">education. It is practiced widely informally and
formally. Strategic planning and decision processes should end with objectives and a
roadmap of ways to achieve them.

One of the core goals when
drafting a strategic plan is to develop it in a way that is easily translatable into
action plans. Most strategic plans address high level initiatives and over-arching
goals, but don't get articulated (translated) into day-to-day projects and tasks that
will be required to achieve the plan. Terminology or word choice, as well as the level a
plan is written, are both examples of easy ways to fail at translating your strategic
plan in a way that makes sense and is executable to others. Often, plans are filled with
conceptual terms which don't tie into day-to-day realities for the staff expected to
carry out the plan.

The following terms have been used in
strategic planning: desired end states, plans, policies, goals, objectives, strategies,
tactics and actions. Definitions vary, overlap and fail to achieve clarity. The most
common of these concepts are specific, time bound statements of intended future results
and general and continuing statements of intended future results, which most models
refer to as either goals or objectives (sometimes
interchangeably).

One model of organizing objectives uses
hierarchies. The items listed above may be organized in a hierarchy of means and ends
and numbered as follows: Top Rank Objective (TRO), Second
Rank Objective, Third Rank Objective, etc. From any rank, the objective in a lower rank
answers to the question "How?" and the objective in a higher rank answers to the
question "Why?" The exception is the Top Rank Objective (TRO): there is no answer to the
"Why?" question. That is how the TRO is defined.

People
typically have several goals at the same time. "Goal congruency" refers to how well the
goals combine with each other. Does goal A appear compatible with goal B? Do they fit
together to form a unified strategy? "Goal hierarchy" consists of the nesting of one or
more goals within other goal(s).

One approach recommends
having short-term goals, medium-term goals, and long-term goals. In this model, one can
expect to attain short-term goals fairly easily: they stand just slightly above one's
reach. At the other extreme, long-term goals appear very difficult, almost impossible to
attain. Strategic management jargon
sometimes refers to "Big Hairy Audacious Goals" (BHAGs) in this context. Using one goal
as a stepping-stone to the next involves goal sequencing. A
person or group starts by attaining the easy short-term goals, then steps up to the
medium-term, then to the long-term goals. Goal sequencing can create a "goal stairway".
In an organizational setting, the organization
may co-ordinate goals so that they do not conflict with each other. The goals of one
part of the organization should mesh compatibly with those of other parts of the
organization.

What are the competing philosophies throughout the play King Lear?

In assessing the primary relationship between Lear and his
daughters, I think that one can see the competing philosophies that collide and leave
all of them as victims in the end.  Lear is a believer in the old ways of tradition.  In
such a setting, the word of the father is taken above all, the role of the parent is
beyond reproach, and there is a natural "pecking order" that sees him at the top and all
else underneath.  This collides with the vision of modernity, where individuals freedom
defies hierarchy and where self interest reigns over all else.  It is in this philosophy
that Regan and Goneril operate.  These two worlds come into direct conflict with one
another when Lear recognizes that his value system is obsolete, that tradition has been
usurped by modernity, and the result is his abandonment.  In this light, I think that
one can see the powerful nature of ideas and philosophies and how they underscore the
action in the drama.

What does Atticus mean when he tells Scout "to delete the adjectives and have the facts" about Jem's strange behavior in To Kill a Mockingbird?

In order to answer this question, Jem's words deserve to
be read again:

readability="10">

He declared Egyptians walked that way; I said if
they did I didn’t see how they got anything done, but Jem said they accomplished more
than the Americans ever did, they invented toilet paper and perpetual embalming, and
asked where would we be today if they
hadn’t?

In this context, Jem
is enthralled to be in 6th grade. In particularly he loved the section on the Egyptians.
He, therefore, began to even imitate the way they walked "sticking one arm in front of
him and one in back of him." 

When Scout questioned him
about this, Jem responded by touting the great inventions of the Egyptians. This is
where Atticus' wise words come in. 

Atticus basically tells
Scout to strip down what Jem is saying to it essential meaning. The Egyptians created
some important things that help us even today. In other words, they were
inventive. 

Another way to look at it is by actually taking
out the adjectives, as Atticus advises. If we did that, we would have: paper and
embalming. The Egyptians did invent these two. 

Determine the indefinite integral of f(x)=1/(5x^2-10x+5)

To determine the indefinite integral, we'll factorize by
5 the denominator.

5x^2-10x+5 = 5(x^2 - 2x +
1)

We notice that the denominator is the result of
expanding the square: x^2-2x+1 = (x-1)^2

We'll re-write the
integral:

Int f(x)dx = (1/5)*Int
dx/(x-1)^2

We'll use the techinque of changing the
variable. For this reason we'll substitute x-1 by t.

x-1 =
t

We'll differentiate both
sides:

(x-1)' = 1*dx

t' =
dt

So, dx = dt

We'll re-write
the integral in t:

Int dx/(x-1)^2 = Int
dt/t^2

Int dt/t^2 = Int
[t^(-2)]*dt

Int [t^(-2)]*dt = t^(-2+1)/(-2+1) = t^(-1)/-1 =
-1/t

But t =
x-1

(1/5)*Int dx/(x-1)^2 = -1/5(x-1) +
C

or

(1/5)*Int
dx/(x-1)^2 = 1/5(1-x) + C

Determine the reminder of the division of polinomials P/Q P=(x+1)^10+(x+2)^10 Q=(x+1)(x+2)

We'll apply division with
reminder.

P=Q1*Q+R

The degree
of the the reminder has to be smaller than the degree of Q. In our case, Q has the
second degree, so the reminder is a first degree
polynomial.

R=aX+b

First,
let's find out the roots of
Q.

Q=(x+1)(x+2)

(x+1)(x+2) =
0

We'll put each factor as
zero.

(x+1) = 0

We'll add -1
both sides:

x = -1

x+2 =
0

We'll subtract 2 both
sides:

x = -2

Now, we'll
substitute the roots of Q, into the expression of division with
reminder.

P(-1) = Q(-1)*Q1+a*(-1)+b, where
P(-1)=1

But Q(-1)=0,
so:

1=0-a+b

-a+b=1
(1)

P(-2) = Q(-2)*Q2+a*(-2)+b, where
P(-2)=1

1=0-2a+b

-2a+b=1 
(2)

From (1) and (2), we'll
have:

-a+b=-2a+b

How do outside influences factor into Sonny's work?"Sonny's Blues" by James Baldwin

In James Baldwin's short story, "Sonny's Blues," a revival
takes place across from his brother's house, and the brother watches it as he has so
many times before.  But, this time, after having lost his little Grace, the brother
watches the meeting with different eyes and heart.  He notices
that

the
music seemed to soothe a poison out of them; and time seemed, nearly, to fall away from
the sullen, belligerent, battered faces, as though they were fleeing back to their first
condition, while dreaming of their
last.

Then, he perceives
Sonny looking at the woman with a wry smile.  He turns and walks across the street, but
the narrator notices for the first time what a musical walk--a slow, loping walk...[he]
imposed on his own half-beat.  After he enters the house, Sonny tells his brother that
listening to the woman's voice reminded him of the simultaneous "warm and cool" feeling
of heroin in the veins:  "It makes you feel--in control.  Sometimes you've got to have
that feeling." Sonny also remarks that it struck him "how much suffering she must have
had to go through--to sing like that."

The woman's singing
gave voice to her suffering, to her emotions.  His playing of the the musical
instrument, the piano, does the same for Sunny that the instrument of her voice does for
the woman.  Later, at the nightclub, Sonny's brother understands the
connection:

I
had never before thought of how awful [causing awe] the relationship must be between the
musician and his instrument.  He has to fill it, this instrument, with the breath of
life, his own.

And, when
Sonny plays,

readability="9">

everthing had been burned out of hit [his face],
and, at the same time, things usually hidden were being burned in by the fire and fury
of the battle which was occurring in him up
there.

His instrument, like
"the very cup of trembling" that the brother perceives glowing above Sunny's head, is
the voice of all that Sonny has experienced and all that he has lived.  Like the woman
who suffered so she could sing as she does, Sonny must play his piano as an expression
of his suffering in the "vivid killing streets" of Harlem.  The murder of his uncle, the
darkness of drugs and crime, the fear, the anguish--all "burned in" and "burned
out" of Sonny as he gives breath to his instrument, expressing all of his emotion in
music.

What was Margaret Atwood’s inspiration for her story “Happy Endings”?

Margaret Atwood took “furtive glee” in her story “Happy
Endings,” writing in what she thought was an experimental and innovative form, only to
discover that the form itself had already been named metafiction. This term describes
fiction that comments on the art of fiction or the telling of stories, forging a
collaboration with the reader and breaking down what is known as the “third wall.”
Atwood’s unusual and unique story parodies such genres as soap opera and pulp fiction,
while the story’s real discourse concerns the nature and craft of storytelling,
particularly, how stories end. “Happy Endings” is broken into six sections—marked A
through F—which, together, form a self-reflexive work on the art of storytelling that
encompasses the author’s ideas about such weighty subjects as sex roles and death.
Atwood creates a miniature instructor’s manual on story writing and stretches the
boundaries of genres to set up plots that reveal where all plots ultimately lead. The
story is a call to action, as well as a revelation of what makes storytelling anything
but easy—all rendered with humor, parody, and cleverness. Ultimately, “Happy Endings”
shows us the lines that separate life and fiction and life and
death.

Atwood further compared writing “Happy Endings” to
finding a white frog. She thought she was being experimental and innovative, only to
discover that the form of what she was creating had already been named meta-fiction.
This term describes a form of fiction that comments on the art of fiction or the telling
of stories and is anchored in self-reflexivity—one of the hallmarks of Post-modernism.
“Happy Endings” is designed around the notion that a reader, whose role is highly
collaborative, knows what is expected and what is supposed to come—but
doesn’t.

Is this a good start to my essay?This is what I have going on for my essay so far. The ward system in municipal politics and the at-large system...

In introductions I normally find to stop them being boring
and to make them interesting you want some kind of initial "hook" that is going to
attract your reader to keep on reading. Your introduction as it stands is good, but it
is hardly different or eye-catching. What you need to do is do some research into the
topic of the essay and come up with some kind of contradictory or challenging statement
that goes to the "heart" of what your essay is all about and start off with that. I
often recommend my students to find a particularly juicy quote to start off with that
lays the ground, so to speak, for the rest of your essay. So that is what I would
recommend for you - maybe go back over your research notes or look up something on the
net concerning this topic and see what you can find. Good luck!

In a paragraph, explain the setting on Chapters 1-4 in The Outsiders.

Although author Susan E. Hinton never reveals the exact
setting of her novel, The Outsiders, it is believed to be that of
Tulsa, Oklahoma--Hinton's home as a teenager. The gang of greasers spend most of their
time on the streets, with the drive-in theatre as one of their primary diversions. At
the drive-in, the boys meet their friends, hit on girls, get in fights, and even watch a
little of the movie. When the three boys--Pony, Johnny and Two-Bit--escort the two girls
back to Two-Bit's house to retrieve his car, they are accosted by a group of Socs in the
blue Mustang. After the girls leave in the Mustang, Pony and Johnny head home. The boys'
homes are in a lower-class neighborhood, far from those of the Socs' wealthy parents.
Both Johnny and Pony decide not to go home; Johnny's parents are fighting, and Darry
hits Pony when he comes home late. They head to another one of their stomping
grounds--the nearby park, which is greaser territory and off-limits to the Socs.
However, the Socs in the blue Mustang cruise by and decide to confront the two greasers.
Pony's and Johnny's lives will change drastically afterward.

Can we live with one adrenal gland?

The adrenal glands produce very important hormones that
are essential to regulate the body's salt levels, blood pressure and its response to
stress. The human body has a very large capacity to adapt. If one adrenal gland has to
be removed due to any cause, the other gland can increase its production of the same and
the body will continue to function with the person noticing little if any
change.

If both the adrenal glands are removed though, a
person has to take medication to replace the functionality of the adrenal
glands.

What details suggest the dehumanizing effects of Dr. Manette’s captivity?A Tale of Two Cities by Charles Dickens

As a result of his fourteen years in captivity, Dr.
Manette has, indeed, aged. In addition, he has also developed a certain disorientation
with time and circumstance.  For instance, when Mr. Lorry and Lucie Manette arrive, he
does not comprehend that he "has a visitor." He looks up momentarily, then resumes his
habitual action of shoemaking. Dickens writes,

readability="11">

The task of recalling him from the vacancy into
which he always sank when he had spoken, was like recalling some very weak person from a
swoon, or endeavouring, in the hope of some disclosure, to stay the spirit of a
fast-dying man.

When Manette
does commit some action, in the "midst of the action he went astray."  His mind wanders
into the vacancy in which it has been kept so long.  After he is brought back to London
and lives with his loving daughter, Charles Darnay wishes to ask permission to marry
Lucie.  In an attempt to be forthright Darnay begins to reveal his true identity, but
Manette stays him, telling Darnay to reveal his secret on the wedding day.  When Darnay
does so, poor Dr. Manette pulls out the shoemaking tools and recommences his habitual
task.  As he does so, he again becomes disorientated, losing a sense of
time:

He had
laid aside his coat and wastcoat; his shirt was open at the throat...and even the old
haggard, faded surface of face had come back to
him.

When Mr. Lorry tries to
pull him back to reality, asking him to look at him, Manette does so,
but

in the old
mechanically submissive manner, without pausing in his
work. 

Manette continues
working on the shoe that, he says, "ought to have been finished long ago."  Even later
in the narrative, when Manette gets better and bravely travels to London to plea on
behalf of his son-in-law, Charles Evremonde, he does not grasp the true nature of the
situation in Paris.  Truly, Dr. Manette's experience of being imprisoned for fourteen
years has left its mark upon him in A Tale of Two
Cities.

When integrate sin x gives -cosx. When integrate sin^2x gives cos^2x.

We'll have to use the
formula:

(sin x)^2 = [1 -
cos(x/2)]/2

We'll integrate both
sides:

Int (sin x)^2 dx = Int [1 -
cos(x/2)]dx/2

We'll use the additive property of
integral:

Int [1 - cos(x/2)]dx/2 = Int dx/2 - Int
cos(x/2)dx/2

Int dx/2 = (1/2)/Int
xdx

Int dx/2 = (x^2)/4 + C
(1)

Int cos(x/2)dx/2 = (1/2)*Int
cos(x/2)dx

(1/2)*Int cos(x/2)dx = (1/2)* sin(x/2)/(1/2) +
C

(1/2)*Int cos(x/2)dx = sin(x/2) + C
(2)

Int (sin x)^2 dx =  (1) +
(2)

Int (sin x)^2 dx = (x^2)/4 + sin(x/2) +
C

So, when integrate (sinx)^2,
the result is not (cosx)^2.

What is characterization? Discuss the various methods that a dramatist or a novelist or a dramatist uses to provide characterizing details.please...

Characterization in drama involves some
different aspects.  In character-driven dramas, for instance, there is implicit
characterization in which the audience is drawn into their inner turmoils as they are
developed over the course of the play. Since the actors who assume these roles must
characterize over an extended period of time, there is usually no direct statement of
who the character is at any particular point so that the audience does not recognize a
realistic characterization right away.  Such playwrights as Anton Chekhov uses this type
of characterization in such plays as The Cherry Orchard in which he
portrays the social climate of Russia when the aristocrats and land-owning gentry were
losing their wealth.  Over the course of the play, the audience perceives that Ranevsky
is unable to adjust to the changes as, when faced with the loss of her beloved orchard,
she is unable to save it. She is a kind and generous woman who is irresponsible
regarding money and life.  After fleeing her tragic past in Paris, she takes a villain
for a lover and is swindled out of her money by him; then, he leaves her for another
woman in this tragicomedy.

In other dramas, however, there
may be stock characters, who represent a certain "type" of person in a simplification;
there may be archetypal characters that represent a "type" in its greatness.  Of course,
in tragedies, especially the classic tragedies such as Oedipus Rex,
there are clear definitions (according to Aristotle's Poetics) of
the tragic hero who must have hubris, an arrogance, and commit a
tragic mistake, hamartia. He/she must also be of a noble nature and
his/her downfall must be of his/her own fault. Nevertheless, the tragic hero's downfall
is not wholly deserved and this downfall does have some positive results.  For instance,
Oedipus learns that he has been married to his mother and has killed his father.  After
blinding himself, he is greatly humbled and turns to his children whom he lives with and
to whom he becomes devoted.

What's scientifically wrong with a person's brain when they are mentally challenged?I want to know the difference in the brain from a normal person...

A mentally challenged person is one  suffering from a
condition of subnormal intellectual and social development. IQ of such a person ranks
significantly below average person. Also the person is less competent in social
functioning as compared to to persons of same age group and cultural
background.

A person may become mentally challenged due to
many diverse causes. Generally condition of most such persons results from a combination
of such factors, that none of which could have produce the condition by itself. The
contributing factors include things like poverty, poor physical health, malnutrition,
insufficient educational advancement, and basic mental
capacity.

In a few cases the condition of a mentally
challenged person may result from a single cause that may be genetic or environmental.
The genetic causes include the presence of an extra chromosome or an abnormal chromosome
in the cells.

Environmental causes may occur before,
during, or after birth of the mentally challenged person. For example it can be caused
by improper mental development of he affected person due to mother catching some types
of diseases or encountering other health problems during pregnancy. Premature birth,
injury during birth, or failure of new born baby to breathe properly may also cause
improper development or damage to the brain resulting in the person becoming mentally
challenged. During childhood brain may be damaged by causes such as as brain infection,
head injury, prolonged high fever, swallowing or breathing poisonous
substances.

Explain - "And she I cherished turned her wheel--Beside an English fire" from "I Travelled Among Unknown Men" by Wordsworth.

In this poem, the speaker is talking about why he will
never again leave England.  At first, it seems to be a patriotic poem.  However, we find
by the end that it is a poem about his love for a woman named Lucy who has died while
the speaker was away.  He does not want to leave England again because it is where she
lived.

The line you cite refers to something that women had
to do in the old days -- spin thread.  Up until at least the early 1800s, most people
made their own clothes and actually made the cloth as well.  The first step was to take
wool or cotton or some other fiber and spin it into thread.  This was done with the use
of a spinning wheel.  The poet is describing Lucy spending time using her spinning wheel
to make cloth.  It is just a metaphorical way to say that England is where she spent her
life.

What is the relationship is between a lack of adequate health care and society's disenfranchised (poorer) class?

One of the important parts of the disenfranchisement of
the poorer class through the denial of basic health care is a relatively simple one. 
When you know that you cannot afford to see a doctor and your only avenue of getting
some access to the system is the emergency room, there is no such thing as preventative
care and it adds to the feeling of disenfranchisement as well as the dangers of constant
illness, etc. that were mentioned in the previous
post.

Those of us lucky enough to have insurance also have
to learn how to navigate the system and get what we need out of a very flawed set up but
we learn these things through experience and often with at least some help from the
system.

For people completely shut out of it, everything
about it is alien and it represents nothing but difficulty and the chances of being
bankrupt because of an accident where a wound gets infected,
etc.

What causes web toes or fingers?

Webbed fingers and toes, otherwise known as "syndactyly"
does not have an exact known cause.

Because of certain and
somewhat common patterns of its appearance however, scientists have linked it to down
syndrome.  Another common connection seems to suggest it is a hereditary genetic
mutation.

In extreme and rare cases there are a number of
genetic "syndromes" that webbed fingers/toes have been linked to.  In one, it is related
to the mother taking a certain drug during the early stages of pregnancy.  For a more
complete list of these you can follow the link below.

What risk was Dr. Rohmer taking in letting Mr. Fairbain be the master of ceremonies in The View From Saturday?

Mr. Homer Fairbain is the deputy superintendant in charge
of instruction in the school district, but for a man with such a lofty position, he is
not very learned. Mr. Fairbain had been the master of ceremonies for the district
playoffs of the Academic Bowl the previous year, and had made quite a mess of things,
showing his ignorance by his inability to read the questions correctly, and embarrassing
the school district in the process. This year, since the competing team is from the
sixth grade instead of the eighth grade as expected, it is anticipated that the audience
for the event will be larger than usual. By letting Mr. Fairbain be the master of
ceremonies again, Dr. Rohmer is taking a chance that the district will again be
embarrassed by Mr. Fairbain's gaffes in front of even more observers than last
year.

Dr. Rohmer actually has little choice but to let Mr.
Fairbain do the job again, however, because it is "his one chance to show the community
that he (has) learned a thing or two." Mr. Fairbain is a good-hearted, humble man,
albeit inept, and he offers to consult some of the remedial reading teachers on staff to
help him read the questions correctly, but Dr. Rohmer reminds him that that might not be
appropriate, as he is technically their boss. In an attempt to avoid disaster, Dr.
Rohmer gives Mr. Fairbain a copy of the questions ahead of time, so he can practice and
prepare to read them without error. On the day of the event, Mr. Fairbain does quite
well at first, but then he mispronounces the name "Geronimo," and is corrected by Julian
Singh. Mr. Fairbain, good-natured as usual, admits his mistake, but then makes things
worse by asking Julian if he is an Indian himself; when Julian gives the qualified
answer that he is "in part what is called East Indian," Mr. Fairbain breaks an unspoken
rule about not commenting about a person's ethnicity in public by asking, "What is your
tribe?" Mr. Fairbain clearly does not understand the difference between East Indian and
American Indian ethnicity, and Dr. Rohmer is mortified. Mr. Fairbain, seeing Dr.
Rohmer's look, mercifully ceases his blundering repartee, and continues on with the
contest (Chapter 7).

What are some causes of irregular heartbeats?

Most everyone from time to time feels the heart " skip a
beat ", this is called a palpitation. These irregular beats can be due to excessive
caffeine intake, physical or emotional stress, metabolic disorders, or they can be
idiopathic in nature. Occasional palpitations do not indicate cardiac
disease.

A more serious situation exist if the occasional
skipped beat turns into a more frequent change in the heart's normal rhythm. This is
called an arrhythmia (dysrythmia). Arrhythmia's can originate from the atria or
ventricles of the myocardium. Most atrial disturbances are less problematic and cause
less harm to the myocardium. Ventricular arrhythmia's, on the other hand, can be fatal.
These are most often caused by electrolyte imbalances in the blood like hypokalemia or
hyperkalemia. Fatal rythmn disturbances may also be due to heart disease like CAD,
coronary artery disease.

Examples of atrial arrythmia's are
AF (atrial fibrillation), and PAT (premature atrial contractions). Examples of deadly
ventricular dysrhythmia's are VT (ventricular tachycardia), and VF (ventricular
fibrillation).

Besides the ending in The Chrysalids, where are other examples of irony?

I think there are plenty of examples of irony in this
text. Remember that irony is the gap between appearance and reality. It is incredibly
ironic that it is amongst the children of one of the most evangelical preachers against
abominations that a "super abomination" in the form of Petra is born. I am sure that
David's father must have been delighted when he found out (not). You might also like to
think about the fact that everyone was so earnestly searching for abominations of the
extra toe variety like Sophie that they were completely oblivious to a far more
insidious abomination that appeared "normal" right beneath their noses. Lastly you might
want to consider the fact that the force that is sent into the Fringes after David,
Petra and Rosalind actually contains one of the people that they are trying to hunt
down, who is therefore able to give valuable information to David and Rosalind and
co-ordinate their defence.

Those are the main forms of
irony. I think there is actually a deeper irony at work about the philosophy of the
Sealanders who come for Petra. It is highly ironic that the woman who comes to take
Petra seems to preach in the same evangelical and arrogant tone that David's father and
the Inspector preach in. Perhaps the new reality of life in Sealand isn't going to be
that great after all...

Why does the “house” of Usher fall?

By speaking of the house, Poe is being allegorical to the
head of a household, the leader of a group, and the foundation of a family or
organization. As the Usher family dissipates as a result of their congenial disease,
their living head of household, Rodderick, is also fading away mentally and
psychologically. Being that he is also dying apparently, the house, the residents, and
visitors alike seem to be decaying slowly into oblivion. Therefore, the House of Usher
(which is also a title given to other aristocratic and powerful families such as House
of Versace, House of Windsor, House of Hanover) is coming to an end, and so are the ones
who carry the name of the house of Usher with it.

How are Samuel Parris, Thomas Putnam, John Hale, and Rebecca Nurse linked with the idea of authority in Act One of "The Crucible?"

Each character features a different relationship to
authority in the play.  For example, Parris and Putnam represent the desire to
consolidate authority into hunting for witches and diverting from their own conditions. 
Putnam advocates the witchhunt aspect of Salem's authority because it will profit his
business and also detract criticism from his practices, while Parris is more interested
in hunting for witches so as to not allow for reflection on his own shortcoming as a
parent and community member.  Rebecca Nurse emerges as one of the voices that rises
against the authority's propensity to engage in a witchhunt.  While not as antagonistic
as Proctor, she is one who believes that the witchhunt approach to which authority is
leaning is not necessary and that to do so would actually be a greater proliferation of
sin than the presence of witches.  Hale's presence as the "outside expert" is one that
possesses some level of sincerity in his role as an authority figure, but one that also
reflects its ability to be corrupted by the desire to consolidate political figure.  In
this light, Hale can be seen as an example of the futility of good intentions when
authority is driven to malevolent ends.

In Book Two, who was Halutherses and what prediction did he make?

Halitherses, the son of Mastor, is an Ithacan prophet. He
was a dear friend of Odysseus', along with Mentor. He is one of the people who remain
loyal to Odysseus even after his long absence. When the suitors first come, he attempts
to stop them but is unsuccessful.

In Book 2, he warns the
suitors that they are ill-fated. Zeus has sent him some symbols of what will eventually
happen. Because Halitherses is an augur (a special kind of prophet who interprets
prophecies from birds), the symbols come in the form of two vicious, fighting eagles.
When Odysseus finally comes home to Ithaca, they will all be punished severely. He tells
them that if they are "wise in time" and stop pursuing Penelope so wickedly, they will
survive. However, if they don't before Odysseus arrices, they will all die. None of the
suitors listen to him. 

Later in the epic, after the
suitors are all dead, Halitherses gives another warning. He tells the families of the
suitors not to take revenge, or more bad things will happen. Half of them listen, but
the other half try to get revenge on Odysseus and Telemachus. Athena swiftly destroys
them all, just as Halitherses predicted. 

Using your analysis of the images in “Dream Deferred”, how do the images represent Walter’s dream in A Raisin in the Sun? -give...

"A Dream Deferred" is full of powerful sensory images
which are undeniably represented in this play, as Hansberry includes the poem in the
published work and references it in the title.  The question is: "what happens to a
dream deferred?"  The answer is a series of possibilities: does it dry up, fester,
stink, crust over, sag, or explode.  It's pretty clear Walter is the one who most
exemplifies these images and emotions of an unrealized
dream. 

Walter wants to do something to have a business of
his own.  We know he's not particular, because he was interested in a dry cleaning
business and now he wants to own a liquor store.  He hates his job working for someone
else (as a chauffeur) and doing anything else would be better than
what he's been doing.  He's distraught that he can't provide for his family without
help, he's angry that black men don't have as many opportunities, and he obviously feels
like he's not doing his job as a man.

"Somebody tell me – tell me, who decides which...
women is suppose to wear pearls in this world. I tell you I am a man – and I think my
wife should wear some pearls in this
world!" 

Despite that
sentiment, he is not able to do what he wishes he could--and some of that is clearly his
own fault.  His anger and frustration are building. 

When
it becomes increasingly clear Walter is not going to get any of the insurance money to
invest, he literally explodes.  He goes and gets drunk; he walks away from his wife in
anger; he is content, for a time, to let his wife get an abortion because a baby feels
like just one more burden; he quits going to work; he fights with his sister; he
disrespects his mother.  He's angry and accusatory and walking around with a giant chip
on his shoulder.  He feels as if he's misunderstood and certainly underestimated, which
is especially hurtful to him:

"WALTER:  Man, I’m a volcano, a giant surrounded
by ants. Ants can’t understand a thing giants talking
about."

The volcano imagery
is certainly apt, given the poem's imagery. 

Mama finally
understands what is happening to her son, and she does give him the money.  Of course,
he is too trusting and he loses the better part of their inheritance.  This is a weight
which causes him to "sag like a heavy load."  It is short-lived, though, as Mama does
what she must to save her family, and especially her son.  The play does end with hope,
and while the Youngers will never be rich, they will, we think, be
content.

It's an interesting twist that the poem lists many
images of discontent and rottenness and sickness and shriveling--ending with an
explosion.  In the play, however, the explosion is not the last
thing; is does happen, but it's not the end.  Instead, there is a new kind of
explosion:

"MAMA:  He finally come into his...manhood today,
didn’t he? Kind of like a rainbow after the rain....
RUTH (Biting her lip,
lest her own pride explode in front of Mama)  Yes,
Lena."

How Walter sees his
life sets the tone for the rest of them.  Walter may still hate being a chauffeur; but
he has something more than he started with, and there is a hope and anticipation for the
entire family as they continue to live their lives. For Walter and his family, the dream
may have been deferred, but it does finally become a reality.

Does "Through with Love" by Destiny's Child have any figurative language in it?

Like many lyrics in pop-culture songs, this song contains
figurative language, but much of it is hard to spot because phrases are common enough
that we overlook them as figures of speech.

Remember that
figurative language or figures of speech (same
thing) include similes, metaphors, and personification, which is a specific kind of
metaphor.  The following lines contain metaphors:

readability="5">

I gave my heart to you
-
Put
aside my smile for you

If you
imagine this literally, you can see how it is a metaphor.  The speaker did not
physically hand over her heart or physically put away her
smile.

Later, the use of "paralyze" should have caught your
attention in this line:

readability="5">

Paralyze my growth for
you

Anytime an author uses
diction (word choice) that seems out of place in context
(frequently done in song lyrics), you can almost be certain figurative language is
used.  Literally, paralyze is a term that means "to make unable to move or act," but it
is typically associated with a medical condition.  Applied figuratively, the comparison
here is between the growth of a relationship and the growth of a
body.

What are the other components of the reaction mixture from Part A that reacts with NaOH before the copper ion? I added sodium hydroxide to...

Cu(NO3)2 is aqueous and exists as Cu(2+) ions and NO3(-)
ions. NaOH is also aqueous and exists as Na+ and (OH)- ions. When the two are mixed
together, the Na+ ions combine with the NO3- ions to form NaNO3 which is aqueous and the
Cu(2+) ions combine with the (OH)- ions to form Cu(OH)2 which is not aqueous and forms a
light blue precipitate. This is an example of a double exchange
reaction.

You say that the reaction takes some time before
you can see the precipitate. But there is no other intermediate compound being formed as
part of the reaction between Cu(NO3)2 and NaOH. All reactions take some time before the
end product is formed after the mixing of the initial compounds. In some, this duration
is very short and they seem instantaneous; in others the result may take longer to show
up.

Calculate in what quadrant is the vertex of the graph of f=x^2-5x+6

The vertex of a parabola   y = ax^2+by+c
is

given by:  (xV,yV ) =  (-b/2a , 
-(b^2-4ac)/4a)....(1)

So the given parabola is y =
x^2-5x+6

a = 1, b = -5 and c =
6

Therefore substituting in
(1)

(xV , yV) ={ - -5/2*1 , ((-5)^2 -4*1+6))/4*1
}

= (5,  1/4) which is in 1st
quadrant.

Who cursed the Lady of Shalott in "The Lady of Shalott"?

In "The Lady of Shalott," no information is revealed
concerning who cursed the Lady, why she is cursed, or how long she's been cursed.  The
"history" of the curse is left ambiguous.

This means, of
course, that those details have nothing to do with what the writer is revealing in his
work.  Whatever is on Tennyson's mind, "who" curses her is not necessary information, so
as readers, we shouldn't spend much time on it.  It's not a part of the work of art. 
It's irrelevant to what the work of art
accomplishes. 

What's signigicant is that the Lady seems to
be completely contented and happy fulfilling her role as a separated artist, until the
song of Lancelot draws her to the casement to hear and see for herself.  Whatever else
is going on in the poem, a rational explanation of and history of the curse is
not.   

How is the more formal nature of a draft different from the informal nature of pre-writing?

Pre-writing is the same as brainstorming.  This means a
few things.  First of all - anything and everything goes.  It is an opportunity to get
every single thought down on paper - even the bad ones that will never make it into the
draft.  Prewriting is best done quickly - and can be written in the same way you might
take notes.  This means shorthand is okay, lists are okay, arrows and circles connecting
ideas are encouraged, scratching out and underlining, all of these things are allowed in
the pre-writing process.

The draft however, even if it is
simply an initial or rough draft - should be written formally - meaning, in complete
sentences which are hopefully organized into paragraphs.  A rough draft does not need to
be perfect, understandably it could go through several changes, but it should be written
in the way the final paper is going to look and sound.

This
is why I encourage my students to write very complete outlines (also part of
pre-writing).  By the time you get to the drafting stage - you do not want to be making
major organizational changes.  It is almost too difficult to do when reading a paper in
full sentences and paragraphs.  It is much easier to look at the skeleton and see where
entire sections need to be tweaked, moved, or completely cut.  It is also easier to see
in the later parts of the pre-writing stage - major points that may be missing.  Once
your paper is in the rough draft stage - it might seem very long (and no doubt, possibly
tedius by this point) - so noticing major holes is a little harder to
do.

What image is used to convey the farmer's poverty in this poem? De merchant got half de cotton De boll weevil got de res' Didn't leave de...

This farmer is apparently a grower of cotton, and
cotton seems to be the image or symbol used here to convey
poverty.  Each line or idea conveys a new level of
poverty.

Whatever crop he was able to
harvest was only half his--he had to give the rest to the merchant, undoubtedly to pay
off the debts he incurred waiting for the money the cotton was supposed to bring him. 
Line two tells us he only got part of the crop that was his--the
cotton bugs (boll weevils) got the rest.

The last three
lines are a bit more ambiguous, though they still use the idea of cotton as linked to
poverty.  Perhaps the farmer only had enough left to buy his wife one dress (made of
cotton), but the "full of holes" image indicates the dress isn't new.  The most likely
explanation, then, is that his wife was down to one dress (and a pretty sad-looking
dress, at that) and he could not afford to get her
another.

Specifically, the images in this poem are of a
rather sparse, bug-infested cotton field, and a moth-eaten
dress.

In Fahrenheit 451, what does Montag think about the old woman on Elm who chooses to die with her books, and where is this found in the book?

You can find this incident towards the end of Part
1.

At first, Montag goes into the house on Elm St. as a
committed fireman.  He goes in intending to destroy the books and the house.  He gets
annoyed with the old woman because she is not playing along -- he wants to do things the
right way.  This shows that he is still a normal
fireman.

But then something happens.  The woman starts to
talk about how she is not going to leave and she implies she's going to die with her
books.  This bothers Montag and he starts trying to persuade her to leave.  Clearly, his
thinking has changed.

Later, he is talking to Millie about
the woman.  He is disturbed by what has happned and he has started to wonder if there
must be something important about books -- otherwise, why would that woman die for
them?

So the interaction with the woman really changes his
thinking about her and about his whole society.

When the old woman's house is raided, why does she light the match in Fahrenheit 451?

In Fahrenheit 451, the woman burns
herself, presumably, to become a martyr for her cause.

Her
suicide raises the stakes.  The novel is full of biblical allusions, and the woman going
up in flames, as Christian martyrs are famous for doing, fits with the allusions and
connects her to Christian martyrs.  Her death is a statement, and as far as Montag is
concerned, a powerful one.  Her death is an old time testimonial.  Her death is a
catalyst for Montag's transformation.  That she cares so much for books she is willing
to die for them moves Montag in the direction of beginning a new, thought-filled
life.

Standing among her books as she, and them, go up in
flames, is an image reminiscent of a martyr being burned at the stake.  She lights the
match herself to demonstrate her free will, and her power to choose.  She willingly
gives up her life to testify to the value of what the firemen are destoying.  And
Bradbury writing her as a martyr for books connects her to the Christian martyr the
Captain tells Montag about. 

Please summarise and explain "Shall I compare thee to a summer's day?" Shall I compare thee to a summer's day? Thou art more lovely and more...

This is one of many of Shakespeare's sonnets that is in
praise of the speaker's love. The speaker starts off with a question, which gives the
sonnet its title, and then it is followed by a series of negative answers, as the poet
declares reasons why he shouldn't compare his love to a summer's day, because his love
is more beautiful than this. The speaker's beloved does bear some resemblances to a
summer's day, but only superficial ones. The first two quatrains concentrate
on the summer day's imperfections rather than on the loved one. Thus we are told that at
times, rough winds shake the buds of summer and also summer is too short. Also, the sun
during summer is much too hot at times or it is overcast by clouds. All of these are
reasons why the speaker rejects comparing his love to a summer
day.

Then, in line 9, comes the turn or shift in focus or
thought. The speaker turns from the faulty summer's day to the beloved, and by the end
of the third quatrain, the speaker has entirely abandoned the opening comparison.
Compared to faulty summer, the "eternal summer" or beauty of the loved one will "not
fade". Also, this loved one can really never die, as thanks to Shakespeare, they have
immortality in verse.

In Shakespeare's sonnets, the last
couplet is often a second turn of great impact, acting as a final summary or explanation
of all that came before. In this sonnet the couplet says, perhaps with some
exaggeration, that by being addressed in this poem, the beloved person has become
immortal.

Do all elements have isotopes. Which element has the largest number of isotopes.

An isotope is a form of an element where the number of
protons, or the atomic number is the same but as the number of neutrons differs, the
atomic mass is different. It is not necessary for all elements to have isotopes though
most usually do have natural isotopes or isotopes which have been artificially created.
Isotopes can be stable or unstable depending on whether they decay or not. Some isotopes
have a half life which is in billions of years and can be taken to be
stable.

The element with the highest number of naturally
occurring isotopes is Tin which has 10 isotopes.

Arrange these biological terms in order of size (from the smallest to the largest): organ, cell, organism, organelle, tissue, system

The smallest item in the list would be organelles.
Organelles are tiny structures within a cell, that help it to function. Example of
organelles are-- nucleus, mitochondria, cell membrane to name a few. Cells are the basic
unit of structure and function of all living things, therefore, cells would have to be
placed second. They are microscopic. A group of similar cells that work together to
perform a specific function, is known as a tissue. Therefore, tissue is next
largest. Examples of  tissues include, muscle tissue, epithelial tissue, adipose tissue.
When different types of tissues work together to perform a function in the body, this
group of tissues forms an organ. An example of an organ is the heart. Inside the heart
are many types of tissue-- cardiac muscle,nerve, blood, connective, etc. The job it
performs is to pump blood.  When various organs work together to perform a specific
function in the body, this makes up a system. An example is the circulatory system. In
this system are many organs that work together. Arteries, veins, capillaries and heart
are all part of the circulatory system. Its job is to circulate blood containing
nutrients and oxygen to cells and to pick up cellular wastes.  All the systems of the
body comprise the organism. An organism is a living thing. It can be as tiny as a
microbe, or a complex as a human. When referring to a multicellular organism, the
correct order from smallest to largest  is-- organelle, cell, tissue, organ, system,
organism.

When one of your appendages "falls asleep," so to speak, is this blood flow related or nerve related?

Many times when you are sitting in the same position for
an extended amount of time you may get a "pins and needles" sensation. Perhaps you have
sat with your legs crossed for too long or slept on your arm too long overnight. Many
times when this happens it is because the communication between the brain and that part
of the body has been cut off. Because of the pressure that is placed on the nerves, they
are unable to transmit impulses correctly. The tingling sensation is also a way that our
bodies tell us that we need to change our positions.

readability="11">

Nerve impulses carry sensation information from
nerve endings in the body to the brain, as well as instructions from the brain to the
parts of the body. When you interfere with this transfer by squeezing the nerve
pathways, you don't have full feeling in that body part, and your brain has trouble
telling the body part what to
do.

In addition to this,
blood supply has been cut off a bit because of the pressure placed on the body
part.

ln e^3 + ln e^3x = 6

Let's try the following method. We'll subtract ln e^3 both
sides:

ln e^3x = 6 - ln
e^3

We'll re-write 6 as:

6 =
6*1

We'll substitute the value 1 by ln
e.

6 = 6*ln e

We'll use the
power property of the logarithms:

6 = ln
e^6

We'll re-write the
equation:

ln e^3x = ln e^6 - ln
e^3

Because the bases are matching, we'll transform the
difference of logarithms from the right side, into a
quotient:

ln e^3x = ln
(e^6/e^3)

Because the bases are matching, we'll apply the
one to one property:

e^3x =
e^(6-3)

e^3x = e^3

Because the
bases are matching, we'll apply the one to one property:

3x
= 3

We'll divide by 3 both
sides:

x =
1

Does a price ceiling imposed by the government result in a shortage or surplus?

A price ceiling imposed by the government will always
(according to economists) result in a shortage of the good or service whose price is
being capped.

The reason for this is that the price will be
capped (presumably) at a level below the market equilibrium.  At this price point, the
quantity demanded will be greater than the quantity supplied.  This will result in a
shortage.

Perhaps the classic example of this (used in many
textbooks) is the case of rent control.  When rents are capped, landlords tend to get
out of the rental business even as more tenants wish to rent at the capped prices.  This
leads to a shortage of apartments.

In Chapter 8, what causes the big blow up between Jack and Ralph?

What causes the conflict at this point in the book is what
causes many of the conflicts between Ralph and Jack.  They have different views of what
their little society needs in order to survive.

Ralph is
worried about the signal fire and the fact that it is near where the beast supposedly
lives.  He really thinks that they need the fire so as to be rescued.  Jack offers his
hunters as guards but Ralph does not respect them.  He thinks that they are just
irresponsible kids who are playing around and not serious about the important
things.

This leads Jack to get angry.  He thinks that his
hunters are the most important part of the society and he thinks that Ralph should give
them more respect and do more of what Jack wants him to do.

In Chapter 8 of The Great Gatsby, how has Gatsby's house changed?

It is clear that as Nick is unable to sleep and feels he
needs to visit Gatsby to make sure he is OK, there is a definite change in the house.
Consider what Nick says:

readability="11">

His house had never seemed so enormous to me as
it did that night when we hunted through the great rooms for cigarettes. We pushed aside
curtains that were like pavilions, and felt over innumerable feet of dark wall for
electric light switches - once I tumbled with a sort of splash upon the keys of a
ghostly piano. There was an inexplicable amount of dust everywhere, and the rooms were
musty, as though they hadn't been aired for many
days.

What is emphasised
through this change is the vastness of the house - highlighting the emptiness of the
space inside but also, implicitly, the emptiness of Gatsby's life. The dust and
mustiness likewise reflect the fact that Gatsby's life and dream is over now - his house
and its state represents his life. Now that he has decided to take the blame for Daisy
for the death of Myrtle Wilson, he knows that all his hopes and ambitions have gone to
dust, just like his house.

What are the elements that unify the plot of The Scarlet Letter?

As the descendent of Puritans, especially an uncle who was
directly involved in the Salem Witchcraft trials, Nathaniel Hawthorne was most concerned
with Puritanism, its hypocrisy, and the resulting treatment of sin. While all three
major characters of The Scarlet Letter have sinned, the secret sin
of Arthur Dimmesdale is torturous to the soul of its owner, while the sin of violating
the heart of a fellow human being is a corrupting sin for Roger Chillingworth, causing
him the very loss of his humanity rendering him a fiend. Thus, for Hawthorne, the
effects of sin and the treatment of sin by the Puritans in their austerity and hypocrisy
and self-deception is the unifying element of Hawthorne's narrative; it is his main
theme.

Hawthorne concludes his novel by referring to this
theme,

No man,
for any considerable period can wear one face to himself, and another to the multitude,
without finally getting bewildered as to which may be
true.

and by expressing his
moral,

"Be
true!  Be true! Show freely to the world, if not your worst, yet some trait whereby the
worst may be
inferred!"

Because Hester has
"been true," she is forgiven her sin and perceived as an "Angel" and caring member of
the community and can live an authentic existence, whereas Chillingworth and Dimmesdale
must dissemble whenever they encounter any members of the community, and in this
falseness of face, they are ruined.

variables and expression: the value in cents of 5 quarters

A variable is an unknown or an assumed value of any thing
till it is known or it is solved..

A variable is any value
varying.

A fixed value is a constant or a known
value.

An expression is a mathematical operation or
operations ( like addition, subtraction, multiplication, or division , powers, roots,
factorials or any  defined compositions)  etc on numbers or
variables.

Here between the number   cents and 5 quarters
we can establish a relation:

Let  5 quarters be equal to x
cents.

So x = 5quarters..........(1) is the relation or
equation.

x is the variable. 5quarters is the known
value.

x can be any thing for which the relation is true or
not true.

We know 1 quarter  = 25 cents. So
,

x cents = 5*25cents , here 5*25 cents is an expression.
So,

x cents = 5*25cents.

x
cents = 125 cents.

x = 125. So x = 125 is the only value
for which reation or equation at (1) is true or holds good. (For any other value of x
the relation does not hold good. Or the relation is not true for values other than
125.)

How were the Jamestown settlers different from those in Salem?

I think that one primary difference between the two groups
might come down to why they each migrated to the new world.  Jamestown was driven for
profit.  The discovery of Jamestown was commissioned by a British company, the Virginia
Company of England, sought to establish a new colony in North  America.  The discovery
of tobacco and other cash crops helped to drive industry and wealth for the company. 
The establishment of materialist motives behind colonization emerged from this.  At the
same time, the founding of areas such as Plymouth and Salem were done so for a pursuit
of religious freedom.  This became the driving force behind why the Puritans came to the
new world and why they practiced a brand of religious worship that was so dogmatic and
driven by spiritual impurity and the castigation of the human soul into original sin. 
In this vacuum, between economic and political control alongside spiritual and religious
pursuit of the good, Miller's play takes place, reflecting both in the Witchcraft
Trials.

In "Everyday Use", what are some of the conflicts that Mama and Dee have?

Interestingly, I think that the conflicts between Mama and
Dee are very closely linked to the theme and the major symbol of this story. I think the
theme of this story has to do with our heritage and our family history and how we
respond to it. We can see this theme through the main symbol of the story and how it is
used.

Clearly the major symbol of this great story is to be
found in the quilts that Dee so desperately wants. Consider how they are presented in
the story:

readability="11">

Out came Wangero with two quilts. They had been
pieces by Grandma Dee, and then Big Dee and me had hung them on the quilt frames on the
front porch and quilted them. One was in the Lone Star pattern. The other was Walk
Around the Mountain. In both of them were scraps of dresses Grandma Dee had worn fifty
and more years ago. Bits and pieces of Grandpa Jarrell's paisley shirts. And one teeny
faded blue piece, about the size of a penny matchbox, that was from Great Grandpa Ezra's
uniform that he wore in the Civil
War.

This description shows
both how valuable they are to the narrator but also what a family history they include
and show. It is clear that the quilts and who they belong to symbolise a far bigger
issue regarding the characters of Dee and Maggie, giving the story its title. Note what
Dee says when her mother declares she had promised them to
Maggie:

readability="6">

"Maggie can't appreciate those quilts!" she said.
She'd probably be backward enough to put them to everyday
use."

The final decision to
give Maggie the quilts is an act of love and of upbuilding of Maggie, for the narrator
rejects Dee's rather pushy claim on the quilts and gives them to Maggie instead. Thus
the quilts can be said to symbolise the heritage of the family, but also the love and
human spirit of Ma for Maggie as she tries to build her daughter up and show her that
she is affirmed and deeply cared for. Of course, it is Maggie who, unlike her sister,
Dee, has not abandoned her family heritage, and thus will use the quilts in a way that
is honouring to the memory of the family history that they
represent.

Thus the major conflict is between Mama, who
believes in her family heritage and holds on to it, allowing it to identify and define
her, and Dee, who has rejected her family heritage in an attempt to embrace an African
identity.

In "The Crucible," what are some examples of the three main types of conflict?The three main conflicts being personal, interpersonal, and impersonal.

I think that one can find different examples of the
conflicts mentioned throughout the work.  John Proctor might represent all of them on
different levels.  On a personal level, John is struggling with his sin of having a
relationship with Abigail and trying to restore his marriage.  He is also struggling
with how his concept of what Salem should be is vastly different from what it now has
become.  In this light, we can see this as part of an impersonal conflict because the
concept of Salem is something with which he struggles.  At the same time, his
interpersonal conflicts present himself between he and his wife and she wanting him to
confess in order to live and he wishing to stand for truth regardless of his
consequences.  This can be an example of an interpersonal conflict because of the fact
that both husband and wife hold opposing views on how action should be
taken.

On a much larger level, I think that we can find
conflict of these types in many characters.  Abigail's accusations and lies create an
interpersonal conflict between what she says and nearly everyone else.  At the same
time, she is struggling with her own personal conflict of not having a sound
psychological foundation of love and trust, never fully receiving it from her parents
who died prematurely or from Reverend Parris, who is incapable of such emotional needs. 
I think that an impersonal conflict can be seen in how Putnam seeks to acquire more
land.  This would be an example of an impersonal conflict between individual and the
natural world, in that he seeks to control more that is not in his control.  At the same
time, the manner in which Putnam acquires land, underbidding those who have been accused
in order to get a good price, is another example of interpersonal conflict in that his
tactic pits those who are struggling against him.  Putnam, himself, is filled with much
in way of resentment towards the people of Salem, reflecting of another personal
conflict.  With all of this in mind, I think that when Tituba says that there are more
witches in Salem, she might not be that far off.  The monster borne of conflict walks
amongst all of them, and us, as well.

factor the expressions a) 18a^3*b^2-27a^4 b) 25y^2-16 c) z^6-144 d)m^3-125

a) We notice that neither term is a perfect square nor a
perfect cube, but they have the common factor 9a^3.

We'll
factorize by 9a^3 and we'll
get:

18a^3*b^2-27a^4 = 9a^3*(2b^2 -
3a)

b) Because the terms are perfect
squares, we'll have in the given expression, a difference of squares which it could be
written according to the rule:

a^2 - b^2 =
(a-b)(a+b)

25y^2-16 = (5y)^2 -
(4)^2

(5y)^2 - (4)^2 = (5y - 4)(5y +
4) 

c) Because the terms are again perfect
squares, we'll have in the given expression, a difference of squares which it could be
written according to the rule:

a^2 - b^2 =
(a-b)(a+b)

 z^6-144 = (z^3)^2 -
(12)^2

(z^3)^2 - (12)^2 = (z^3 + 12)(z^3 -
12)

Because of the fact that 12 is not a
perfect cube, although z^3 is, the brackets cannot be factored further
more.

d) Because the terms are perfect cubes, we'll have in
the given expression, a difference of cubes which it could be written according to the
rule:

a^3 - b^3 = (a-b)(a^2 + a*b +
b^2)

a^3 = m^3 and b^3 =
(5)^3

m^3-125 = m^3 -
5^3

m^3 - 5^3 = (m-5)(m^2 + 5*m +
25)
