The parent cosine function is transformed to create function d.

storchak [24]

Using translation concepts, it is found that the parent cosine function undergoes these following transformations:

Horizontal shift of 1 unit to the right.

Vertical shift of 5 units up.

The frequency was multiplied by 2.

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

The parent cosine function is given by:

$f(x) = \cos{x}$

The translated function is given by:

$d(x) = \cos{(2x - 1)} + 5$

The changes were as follows:

1 was subtracted at the domain, hence it had a horizontal shift of 1 unit to the right.

5 was added to the function, hence it had a vertical shift of 5 units up.

The domain was multiplied by 2, hence the frequency was multiplied by 2.

Find the height of a right cylinder with surface area 160pie square units and radius 5 units

jenyasd209 [6]

Given:

Radius of a cylinder = 5 units.

Surface area of the cylinder = $160\pi$

To find:

The height of the right cylinder.

Solution:

Surface area of a cylinder is:

$A=2\pi rh+2\pi r^2$

Where, r is radius and h is the height of the cylinder.

Putting $r=5, A=160\pi$ in the above formula, we get

$160\pi =2\pi (5)(h)+2\pi (5)^2$

$160\pi =10\pi h+2\pi (25)$

$160\pi =10\pi h+50\pi$

Subtract $50\pi$ from both sides.

$160\pi -50\pi=10\pi h$

$110\pi=10\pi h$

Divide both sides by $10\pi$ .

$\dfrac{110\pi}{10\pi}=h$

$11=h$

Therefore, the height of the cylinder is 11 units.

An unknown number x is at most 10. Which graph best represents all the values of x?

barxatty [35]

Answer:

The Answer is D Number line graph with closed circle on 10 and shading to the left. I took the test and got it right.

a number is at most 10 so it could be ten so it is a closed circle. it is shading to the left because no more than than ten
