The excerpt that BEST demonstrates the author’s use of foreshadowing in “The Signalman” is “My good fellow, what should I do there? However, be that as it may, I never was there, you may swear.”  The answer is letter C. It is clear that in this sentence that what the narrator is pointing out is actually heaven and he has not gone there except this very moment.

The length of the base of a rectangular pyramid is tripled, the width of the base remains the same, and the height of the pyramid is divided by 7. What volume formula reflects these changes?

[ad_1]

Answer with Step-by-step explanation:

The volume of a rectangular pyramid is given by:

V=lbh/3

Where l is the length

b is the breath  

and h is the height.

Now, l’,b’ and h’ be new length,breath and height

Then, l’=3l

b’=b

and h’=h/7

New volume=V’=l’b’h’/3

                         = dfrac{3ltimes btimes dfrac{h}{7}}{3}

                         = dfrac{lbh}{7}

Hence, Volume formula which reflects these changes is:

dfrac{lbh}{7}

If the instructions for a problem ask you to use the smallest possible domain to completely graph two periods of y = 5 + 3 cos 2(x – pi divided by three), what should be used for Xmin and Xmax? Explain your answer.

[ad_1]

The correct given equation is:

y = 5 + 3 cos 2 (x – π/3)

 To answer this
problem, we must remember that:

y = A cos [w(x – π)], the period is 2 π / w and the phase shift is π (the
beginning of one period)

Rewriting the given equation to this form,

y = 5 + 3cos [2(x – π/3)] 

Therefore,

period = 2 π / 2 = π
phase shift = π /3 

So to create two periods, you need an interval of
2 π
If you start at π /3, you’ll start and end at the max of the cos
function.

Therefore,

 [Xmin , Xmax] = [π /3 ,
7 π /3]
would create a complete graph of 2 periods.

 

ANSWER: [π /3 , 7 π /3]

We have to go backwards:
After the discount in July ( 50 % ), the cost of jeans is $25.50
So the price before this discount was 2 * $22.50 = $45
In June, the price was reduced by 25%.
45 ——————75%
x ——————–100 %
45 : x = 75 : 100
45 * 100 = 75 x
4,500 = 75 x
x = 4,500 : 75
x = $60
Finally, in May the price was 250% of its wholesale cost.
60 —————– 250%
x ——————-100 %
60 : x = 250 : 100
6,000 = 250x
x = 6,000 : 250
x = $24

The First Reconstruction Act divided the South into how many military districts? three five seven ten

[ad_1]

1- The correct answer is B, as one result of the Great Society was that the lives of many underprivileged Americans improved.

The Great Society was a set of US national reform programs announced by President Lyndon B. Johnson for the first time in a speech at Ohio University on May 7, 1964 and more fully illustrated on May 22, 1964 at the University of Michigan. These reform programs were subsequently presented to the Congress of the United States and largely approved during the 1960s, thanks to the consent of its supporters of the Democratic Party.

Two main goals of social reforms were the elimination of poverty and racial injustice. During this period new large spending programs were launched in the fields of education, medical care, urban problems and transport. Johnson’s “Great Society” was linked, in its objectives and policies, to President Franklin Delano Roosevelt’s New Deal program.

Some proposals of the Great Society resumed initiatives contained in the New Frontier program, interrupted by the tragic death of President John F. Kennedy. Johnson’s success in promoting and endorsing his reforms depended on his considerable congressional political influence, his persuasion, and the favorable historical circumstances resulting from the 1964 presidential elections, which allowed the Democratic Party to dominate Congress and to elect the House of Representatives with the largest number of exponents of the liberal current since 1938.

The evolution of the Vietnam war and the massive involvement of the American military machine in the conflict, however, partly undermined the success of the “Great Society” program. Growing, huge expenditures for the continuation of the war made more difficult to finance the reform programs. Representatives of the Democratic Party against the war in Vietnam complained that military spending decisively stifled the Great Society program. On the whole, however, despite growing political and economic difficulties, which forced the administration to eliminate or reduce the financing of some projects, President Johnson managed to activate a series of programs of great importance, including Medicare, Medicaid, the Older Americans Act and the federal education funding, which are still active.

2- The correct answer is C, as the Immigration and Nationality Act of 1965 was necessary because the previous existing American immigration policies were discriminatory.

On October 3, 1965, President Lyndon B. Johnson signed the law into effect, saying: “The [old] system violates the basic principle of American democracy, the principle according to which the valuation and reward of each man should be established on the basis of his merits as a man. It has been anti-American in the highest sense, because it has been unfaithful to the faith that led thousands to these shores, even before we were a country. ”

Imagine tossing a coin: What are your chances for tossing a head? What are your chances for tossing a tail? A coin is tossed 10 times: How many times do you expect to get heads? How many times do you expect to get tails? Using this data for the 10 coin tosses, calculate and record the deviation observed from what you expected using the following formula: The more the experimental results deviate from the expected results, the more the deviation value will approach the value of 1.0. As your results get closer to the expected results, the deviation is smaller and nears the value of 0.0. Interpret the meaning of the deviation value you obtained. A coin is tossed 100 times: How many times do you expect to get heads? How many times do you expect to get tails? Using this data for 100 coin tosses: Calculate the deviation for the 100 tosses. The 100 coin tosses are repeated. The results are added to the results of the first 100 coin tosses. How many times do you expect to get heads out of the 200 tosses? How many times do you expect to get tails out of the 200 tosses? Using this data for the 200 coin tosses: What is the deviation for the 200 tosses? How does increasing the total number of coin tosses from 10 to 100 affect the deviation? How does increasing the total number of tosses from 100 to 200 (or more) affect the deviation? What two important probability principles were established in this exercise? With two coins, both coins are tossed 100 times. How many times do you expect to get 2 heads? How many times do you expect to get 2 tails? How many times do you expect to get one head and one tail? The percent of occurrence is the obtained results divided by the total tosses and multiplied by 100. Using this data for the two coins being tossed 100 times. Calculate the percent occurrence for each combination: What is the percent of occurrence for two heads? What is the percent of occurrence for two tails? What is the percent of occurrence for one head and one tail?

If the telescope is 1 m deep and 8 m wide, how far is the focus from the vertex? 1 2 4 16 Find the vertex, focus, directrix, and focal width of the parabola. negative 1 divided by 12 times x squared = y

[ad_1]

First, let me introduce the general equation of the parabola:

(x-h)^2 = +/- 4a(y-k) or (y-k)^2=+/- 4a(x-h), where

(h,k) are the coordinates of the vertex
a is the distance of the vertex to the focus
4a = length of lactus rectum or the focal width

If the equation contains (x-h)^2, then the parabola passes the x-axis twice. Similarly, (y-k)^2 passes the y-axis twice. If the sign is (-), it opens to the left(if y-axis) or downward (if x-axis). If the sign is (+), it opens to the right(if y-axis) or upward (if x-axis). 

The equation of the parabola is -1/12 x^2 = y. Rearranging to the general form:

x^2 = -12y
Therefore, 

-4a = -12
4a = 12
a = 3, and the parabola is facing downwards.

The vertex is (0,0) at the origin.
The focus is (0,-3). Since it is negative, the focus is situated downwards, hence -3.
The directrix is the mirror image of the focus. Hence, it is a line passing +3 on the y-axis. y=3
Focal width is 4a which is equal to 12 units.

Alexi divided 256 by 16. Which could he have been converting? A. 256 ounces to pounds B. 256 pounds to ounces C. 256 pounds to tons D. 256 tons to pounds

[ad_1]

Answer:

3 hours.          

Step-by-step explanation:

Let x be the time taken by shoe repairman to repair one pair.

We have been given that his assistant, who takes twice as long to repair a pair of shoes. So time taken by his assistant to repair one pair of shoes would be 2x.

The number of pair of shoes repaired by repairman in one hour would be frac{1}{x}.

The number of pair of shoes repaired by assistant in one hour would be frac{1}{2x}.

We have been given that together they can fix 16 pairs of shoes in an eight-hour day. We can represent this information in an equation as:

frac{1}{x}+frac{1}{2x}=frac{8}{16}

frac{1}{x}+frac{1}{2x}=frac{1}{2}

Let us have a common denominator.

frac{2*1}{2*x}+frac{1}{2x}=frac{1}{2}

frac{2}{2x}+frac{1}{2x}=frac{1}{2}

frac{2+1}{2x}=frac{1}{2}

frac{3}{2x}=frac{1}{2}  

Upon cross multiplying our equation we will get,

2x*1=3*2

2x=3*2

frac{2x}{2}=frac{3*2}{2}

x=3

Therefore, it take 3 hours for the repairman to fix one pair of shoes by himself.

-From a article I have read.-

As a literary genre, a memoir (from the French: mémoire from the Latin memoria, meaning “memory”), or a reminiscence, forms a subclass of autobiography – although the terms ‘memoir’ and ‘autobiography’ are today almost interchangeable. The author of a memoir may be referred to as a memoirist.

***Nature of Memoirs***

Memoirs may appear less structured and less encompassing than formal autobiographical works as they are usually about part of a life rather than the chronological telling of a life from childhood to adulthood/old age. Traditionally, memoirs usually dealt with public matters, rather than personal, and many older memoirs contain little or no information about the writer, and are almost entirely concerned with other people. They tended to be written by politicians or people in court society, later joined by military leaders and businessmen, and often dealt exclusively with the writer’s careers rather than their private life. Modern expectations have changed this, even for heads of government. Like most autobiographies, memoirs are generally written from the first person point of view.

Gore Vidal, in his own memoir Palimpsest, gave a personal definition: “a memoir is how one remembers one’s own life, while an autobiography is history, requiring research, dates, facts double-checked.” It is more about what can be gleaned from a section of one’s life than about the outcome of the life as a whole.

Contemporary practices of writing memoirs for recreational, family or therapeutic purposes are sometimes referred to as legacy writing or personal history. Such products may be assisted by professional or amateur genealogists, or by ghostwriters.

***Types of Memoir***

Memoirs have often been written by politicians or military leaders as a way to record and publish an account of their public exploits. In the eighteenth century, “scandalous memoirs”, allegedly factual but largely invented, were written (mostly anonymously) by prostitutes or libertines: these were widely read in France for their vulgar details and gossip. In another vein, the pagan rhetor Libanius framed his life memoir as one of his orations, not the public kind, but the literary kind that would be read aloud in the privacy of one’s study. This kind of memoir refers to the idea in ancient Greece and Rome, that memoirs were like “memos,” pieces of unfinished and unpublished writing which a writer might use as a memory aid to make a more finished document later on.

Women writers have been prominent amongst those combining the memoir form with historical non-fiction writing. Examples include Jung Chang’s Wild Swans. Maxine Hong Kingston’s book The Woman Warrior is an example of a memoir that combines factual material with fictional material as it tells the author’s story and the story of her family.

Some professional contemporary writers such as David Sedaris and Augusten Burroughs have specialised in writing amusing essays in the form of memoirs. To some extent this is an extension of the tradition of newspaper columnists’ regular accounts of their lives. (Cf. the work of James Thurber which often has a strong memoir-like content).

Another category of memoir is the eyewitness account of history by onlookers to major events or particular eras; Slave narratives (e.g. the memoirs of Frederick Douglass) fall into this category as do those by Primo Levi and Elie Wiesel.

Answer:

                The point that lie on the line is:

                        B.  (1,1)

Step-by-step explanation:

We are given that a line passes through the point (0,-1) and has a slope of 2.

We know that the equation of a line passing through (a,b) and having slope m is given by:

           y-b=m(x-a)

Here we have:  (a,b)=(0,-1) and m=2

This means that the equation of line is:

y-(-1)=2(x-0)\\y+1=2x\\y=2x-1

Now we will check which option is true.

A)

                (2,1)

when x=2

we have:

y=2times 2-1\\\y=4-1\\\y=3neq 1

Hence, option: A is incorrect.

B)

                     (1,1)

when x=1

we have:

y=2times 1-1\\\y=2-1\\\y=1

                Hence, option: B is correct.

C)

                      (0,1)

when x=0

we have:

y=2times 0-1\\\y=0-1\\\y=-1neq 1

Hence, option: C is incorrect.

Seventeen minus 6 times 10 divided two plus twelve

[ad_1]

Answer:  The correct option is (C). 10 = square root of the quantity of x minus 8 all squared plus y minus 9 all squared

Step-by-step explanation:  Given that the segment AB has point A located at (8, 9). The distance from A to B is 10 units.

We are to select the correct option that could be used to calculate the coordinates for point B.

Let, (x, y) be the co-ordinates of point B.

According to distance formula, the distance between two points (a, b) and (c, d) is given by

d=sqrt{(c-a)^2+(d-b)^2}.

Therefore, the distance between the points A(8, 9) and B(x, y) is given by

d=sqrt{(x-8)^2+(y-9)^2}.

Since, distance between A and B is 10 units, so

d = 10.

Therefore,

10=sqrt{(x-8)^2+(y-9)^2}.

Thus, the correct statement is

10 = square root of the quantity of x minus 8 all squared plus y minus 9 all squared.

Option (C) is correct.
