Answer:

  (a)  vertical compression by a factor of 1/3

Step-by-step explanation:

We can see that g(x) = 1/3f(x). Multiplying a function by a constant scales the graph vertically by that factor. When the magnitude of the factor is more than 1, we say the graph is "stretched." When it is less than 1, we say the graph is "compressed" by that factor.

Here, the scale factor is 1/3, so the graph is "vertically compressed by a factor of 1/3."

_____

Additional comment

My personal preference is for compression to be described by the factor the graph is divided by. I would call g(x) a compression of f(x) by a factor of 3. Modern curriculum authors disagree, calling it compression by a factor of 1/3.

Be careful. Using the currently accepted language, a stretch is always by a number larger than 1, and a compression is always by a number less than 1. This rules out choices C and D simply on the basis of the language used.

__

For many graphs, vertical scaling and horizontal scaling can be interchanged. We note that g(x) is wider than f(x), so could be stretched horizontally by some factor. That factor would be √3. The equation using a horizontal stretch factor would be g(x) = (x/√3)^2. Replacing x by x/k is a stretch by a factor of k in the horizontal direction.

Answer:

  (3)  12

Step-by-step explanation:

Let x represent the length of leg XY. Then the length of YZ is x/2 and the area  of the right triangle is ...

  A = 1/2bh

  A = 1/2(x)(x/2) = x²/4

  36 = x²/4 . . . . . use the given value for area

  144 = x² . . . . . . multiply by 4

  √144 = 12 = x . . . . . take the square root

The length of leg XY is 12 cm.

The U.S. Census Bureau conducts a study to determine the time needed to complete the short form. The Bureau surveys 200 people. The sample mean is 8.2 minutes. There is a known standard deviation of 2.2 minutes. The population distribution is assumed to be normal. Which distribution should you use for this problem

Answers

Answer:

The z-distribution should be used for this problem.

Step-by-step explanation:

The population distribution is assumed to be normal. Which distribution to use?

If we have the standard deviation for the sample, we use the t-distribution.

If we use the standard deviation for the population, we use the z-distribution.

There is a known standard deviation of 2.2 minutes.

This means that 2.2 is the population standard deviation, and thus, the z-distribution should be used for this problem.

AD=7, BD=3, DE=6. Find BC

Answers

Answer:

the answer to this is 10 i think sorry if it is wrong

Step-by-step explanation:

The triangles are similar and the measure of BC = 60/7 units

What are similar triangles?

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the first triangle be ΔABC

Let the second triangle be ΔADE

Now , ΔABC and ΔADE are similar triangles

where corresponding sides of similar triangles are in the same ratio

So , AD / AB = DE / BC

On simplifying , we get

7 / 10 = 6 / BC

Multiply by BC on both sides , we get

BC ( 7/10 ) = 6

Multiply by 10 on both sides , we get

7BC = 60

Divide by 7 on both sides , we get

BC = 60/7

Hence , the measure of BC = 60/7 units

D. (.375, .724)
E. (.3785, .7195)

Answers

Answer:

A. (-2.28, 3.38)

Step-by-step explanation:

The confidence interval of the slope :

b ± Tcritical*SE

Tcritical at 95%, df = n - 2 = (15 - 2) = 13

Tcritical = 2.160369

b = slope Coefficient = 0.54924

S.E = 1.311

Hence, we have :

Confidence interval = 0.54924 ± (2.160369 * 1.311)

Confidence interval = 0.54924 ± 2.832243759

Lower boundary = 0.54924 - 2.83224 = - 2.283

Upper boundary = 0.54924 + 2.83224 = 3.3814

Answers

Answer:

 

1/25, 1, 625

Step-by-step explanation:

The value of the function at f(–1), f(0), and f(2) will be 1/25, 1, 625 thus option (d) is correct.

What is a function?

A certain kind of relationship called a function binds inputs to essentially one output.

In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.

As per the given function,

f(x) = [tex]5^{2x}[/tex]

Put x = -1

f(-1) = 5⁻² = 1/5² = 1/625

Put x = 0

f(0) = 5⁰ = 1

Put x = 2

f(2) = 5²ˣ² = 5⁴ = 625

Hence "The function's value at f(-1), f(0), and f(2) is 1/25, 1, 625".

Answer:

Timmy's tubes = 11.25$

Fred's floats = 11.375$

Step-by-step explanation:

For Timmy's tubes

We use unitary method to solve

For 2 1/2 hours, it charges $18.75

So, for 1 1/2 hours it charges $11.25

Similarly for Fred's floats

Base fee = $2

Fee per hour = $6.25

So, for 1 1/2 hour fee = 2 + 6.25 + 3.125 = $11.375

So, Terry should choose Timmy's tubes

well, let's see, what do we know about Timmy's Tubes, is a direct variation equation, since he's charging depending on the hours it's rented, thus

[tex]\qquad \qquad \textit{direct proportional variation} \\\\ \textit{\underline{y} varies directly with \underline{x}}\qquad \qquad \stackrel{\textit{constant of variation}}{y=\stackrel{\downarrow }{k}x~\hfill } \\\\[-0.35em] \rule{34em}{0.25pt}[/tex]

[tex]\stackrel{\textit{\underline{c}ost varying with \underline{h}ours}}{c = kh}\qquad \textit{we know that } \begin{cases} c=18.75\to \frac{75}{4}\\ h=1\frac{1}{2}\to ~\hfill \frac{5}{2} \end{cases} \\\\\\ \stackrel{cost}{\cfrac{75}{4}}=\stackrel{hours}{\cfrac{5}{2}h}\implies 2\cdot 75=4\cdot 5h\implies 150=20h\implies \cfrac{150}{20}=h\implies \cfrac{15}{2}=h \\\\\\ therefore\qquad c=\cfrac{15}{2}h\impliedby \textit{Timmy's rate}[/tex]

now, Fred charges $2 flat right off, plus $6.25 for every added hour, so Fred's equation will more or less be

1 hour 2 + 6.25(1)

2 hours 2 + 6.25(2)

3 hours 2 + 6.25(3)

h hours 2 + 6.25(h)

1)

how much will Timmy charge for 1 1/2 hour?

[tex]c = \cfrac{15}{2}\cdot \stackrel{h}{1\frac{1}{2}}\implies c = \cfrac{15}{2}\cdot \stackrel{h}{\cfrac{3}{2}}\implies c = \cfrac{15}{4}[/tex]   or just 3.75

how much will Fred charge for the same time?

[tex]c=2+6.25\left( \frac{3}{2} \right)\implies c=9.375[/tex]

2)

using only $12 for each, who is the better bargain?

[tex]\stackrel{\textit{Timmy's}}{c = \cfrac{15}{2}h}\implies 12=\cfrac{15h}{2}\implies 24=15h\implies \cfrac{24}{15}=h\implies \boxed{1.6=h} \\\\\\ \stackrel{\textit{Fred's}}{c = 2 + 6.25h}\implies 12=2+6.25h\implies 10=6.25h \\\\\\ \cfrac{10}{6.25}=h\implies \boxed{ 1.6=h}[/tex]

well, let's notice, Terri is going to get the same amount of hours with either, so, it really doesn't matter, both will only give 1.6 hours, or 1 hour and 36 minutes.

This king once fell very illso ill that nobody thought he could live. His sons were very much grieved at their father's sickness; and as they were walking together very mournfully in the garden of the palace, a little old man met them and asked what was the matter. They told him that their father was very ill, and that they were afraid nothing could save him. I know what would, said the little old man; it is the Water of Life. If he could have a draught of it he would be well again; but it is very hard to get. Then the eldest son said, I will soon find it: and he went to the sick king, and begged that he might go in search of the Water of Life, as it was the only thing that could save him. No, said the king. I had rather die than place you in such great danger as you must meet with in your journey. But he begged so hard that the king let him go; and the prince thought to himself, If I bring my father this water, he will make me sole heir to his kingdom.Then he set out: and when he had gone on his way some time he came to a deep valley, overhung with rocks and woods; and as he looked around, he saw standing above him on one of the rocks a little ugly dwarf, with a sugarloaf cap and a scarlet cloak; and the dwarf called to him and said, Prince, whither so fast? What is that to thee, you ugly imp? said the prince haughtily, and rode on.But the dwarf was enraged at his behavior, and laid a fairy spell of ill-luck upon him; so that as he rode on the mountain pass became narrower and narrower, and at last the way was so straitened that he could not go to step forward: and when he thought to have turned his horse round and go back the way he came, he heard a loud laugh ringing round him, and found that the path was closed behind him, so that he was shut in all round. He next tried to get off his horse and make his way on foot, but again the laugh rang in his ears, and he found himself unable to move a step, and thus he was forced to abide spellbound.7Select the correct answer.Based on the passage, who is most likely the major character in the story?A.
