True, that is known as the verteical line test, baicaly it tests if there is only 1 y value corsponting with 1 x value

true

Arrange the parabolas with respect tonthe postion of their vertices from left to right

agasfer [191]

Answer:

The correct answer for this question is this one:

If the x position of the vertex for f(x) is k then :

1. f(k) => 4x+3=k, x = (k-3)/4 = (k/4)-(3/4)

2. x = k+3

3. x = (k+1)/2 = (k/2)-(1/2)

4. x = 2(k+2) = 2k+4

5. x = k+7

6. x = k-3

7. x = k-2

So the order depends on the original position of the vertex k, e.g for k=0 the positions would be:

1. -3/4

2. 3

3. -1/2

4. 4

5. 7

6. -3

7. -2

So, therefore, the order would be 6 7 1 3 2 4 5

Help me with this pleaae

Answer:

(D) 30pi inches

Step-by-step explanation:

First, we use the given volume, the given height, and the formula of the volume of a cylinder to find the radius of the base. Then we use the radius of the base to find the circumference of the base.

$volume = \pi r^2 h$

$volume = 6750 \pi~in.^3$

We set the formula equal to the volume and replace h with 30 in.

$\pi r^2 h = 6750 \pi~in.^3$

$\pi r^2 \times 30 ~in. = 6750 \pi~in.^3$

Divide both sides by 30pi in.

$r^2 = 225 ~in.^2$

Take the square root of each side.

$\sqrt{r^2} = \sqrt{225 ~in.^2}$

$r = 15~in.$

The radius of the base is 15 in.

Now we use the radius of the base and the formula of the circumference of a circle to find the answer.

$circumference = 2 \pi r$

$circumference = 2 \pi \times 15~in.$

$circumference = 30 \pi ~in.$
