Select the correct statements in the passage.
Hillary's teacher asked her to write a description of the transformations to the parent cosine function that would result in this function.
h(x) = -3cos(21 – 7) + 4
Which statements in her description are true about function h?
To create the graph of function h, the graph of the parent function is horizontally compressed by a factor of 2. Then it undergoes a phase shift left 2 units. Next it is
rof.
vertically compressed by a factor of -3 and vertically shifted up 4 units
The period of function h is half the period of the parent function, and it has an amplitude 3 units greater than that of the parent function

Answer:

Surface area of the right triangular prism = 180 m²

Step-by-step explanation:

Surface area of the given right triangular prism = Surface area of triangular sides + Surface area of the rectangular surfaces

Surface area of the triangular sides = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                                                           = [tex]\frac{1}{2}(AB)(AC)[/tex]

By applying Pythagoras theorem in ΔABC,

BC² = AB² + AC²

(13)² = 5² + (AC)²

AC² = 169 - 25

AC = 12 m

Therefore, area of the triangular sides = [tex]\frac{1}{2}(5)(12)[/tex] = 30 m²

Area of the rectangular side with dimensions 5m × 4m,

= 5 × 4

= 20 m²

Area of the rectangular side with dimensions 13m × 4m

= 13 × 4

= 52 m²

Area of the rectangular side with dimensions 12m × 4m

= 12 × 4

= 48 m²

Total surface area of the prism = 2(30) + 20 + 52 + 48

= 180 m²

Answer:

(0,0)

Step-by-step explanation:

The y-intercept is when the line touches the y axis on the graph. In this case, it is touching the origin.

Answer:

(1, 2)

Step-by-step explanation:

Use the midpoint formula

x1 + x2 / 2 ,  y1 + y2 / 2

-2 + 4 / 2 ,  -2 + 6 / 2 =

( 1, 2 )

Given:

The rate of interest on three accounts are 7%, 8%, 9%.

She has twice as much money invested at 8% as she does in 7%.

She has three times as much at 9% as she has at 7%.

Total interest for the year is $150.

To find:

Amount invested on each rate.

Solution:

Let x be the amount invested at 7%. Then,

The amount invested at 8% = 2x

The amount invested at 9% = 3x

Total interest for the year is $150.

[tex]x\times \dfrac{7}{100}+2x\times \dfrac{8}{100}+3x\times \dfrac{9}{100}=150[/tex]

Multiply both sides by 100.

[tex]7x+16x+27x=15000[/tex]

[tex]50x=15000[/tex]

Divide both sides by 50.

[tex]x=\dfrac{15000}{50}[/tex]

[tex]x=300[/tex]

The amount invested at 7% is [tex]300[/tex].

The amount invested at 8% is

[tex]2(300)=600[/tex]

The amount invested at 9% is

[tex]3(300)=900[/tex]

Therefore, the stockbroker invested $300 at 7%, $600 at 8%, and $900 at 9%.

Answer:

I need use this 29.76 91.5 180 188.93 223.07 for what? Can you explain me what I need to do? please O_O

Step-by-step explanation:

Answer:

223.07

Step-by-step explanation:

Hey There!

So the first step of this problem is to find the equation for the area of a parallelogram and the area of a circle

The area of a parallelogram is equal to bh

[tex]base x height[/tex]

the base is 20 and the height is 15

20x15=300

Now we want to find the equation for area of a circle

to find the area of the circle we use the formula [tex]A = pi xr^{2}[/tex]

A = π x radius²

the radius is the diameter divide by 2

14/2=7 so the radius is 7

now we just plug 7 into the area of a circle formula

7²=49

49x3.14=153.86

But because it is a semi circle we divide by 2

153.86/2=76.93

Now to find the area of the object we subtract 76.93 from 300

300-76.93=223.07

Therefore the area of that object is 223.07

Answer:

  have the child arrange the tokens in groups of 5. none left = divisible by 5

Step-by-step explanation:

A number is divisible by 5 if there is no remainder when it is divided into 5 parts. Using "manipulatives," this can be shown a couple of ways:

  1) deal the tokens to 5 piles (each pile will have the same number)

  2) group the tokens into groups of 5 (no tokens will be left over)

Answer:

For the part that contains organic matter your answer is, 35 negative result

For the part that does not contain organic matter your answer is, 60 positive result

Step-by-step explanation:

If we pay attention to the part that contains organic matter the total amount 700 and 665 is positive, so subtract them 700-665 to get 35 negative result

For the part that does not contain organic matter the total amount is 300, and 240 of it is negative, so subtract 240 from 300 to get 60 positive result

Answer:

43.6/21.2

Step-by-step explanation:

convert it into fraction since it will result in an irrational number.

Answer:

2.06

Step-by-step explanation:

43.6 / 21.2 = 2.05660

There are 3 significant figures so your answer should have 3 digits

2.05660 = 2.06

Answer:

E. -1.48

Step-by-step explanation:

The test statistic is:

[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the expected value, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

A market research analyst claims that 32% of the people who visit the mall actually make a purchase.

This means that:

[tex]\mu = 0.32[/tex]

[tex]\sigma = \sqrt{0.32*0.68} = 0.4665[/tex]

You stand by the exit door of the mall starting at noon and ask 82 people as they are leaving whether they bought anything. You find that only 20 people made a purchase.

This means that [tex]n = 82, X = \frac{20}{82} = 0.2439[/tex]

The value of the test statistic is about:

[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]t = \frac{0.2439 - 0.32}{\frac{0.4665}{\sqrt{82}}}[/tex]

[tex]t = -1.48[/tex]

So the correct answer is given by option E.

Hi

Answer:

x=24

Step-by-step explanation:

2x+13+3x+47=180

we know that this is true because m is a line so 47 and 3x make up part of a 180 degree angle. The last part is 2x+13 because of corresponding angles are equal with parallel lines

we can simplify this like this

5x+60=180

5x=120

x=24
