Answer:

V = 2143.573333333333.... in³

Step-by-step explanation:

Formula for volume -> V = 4/3 πr³

We know the circumverence now we need to et the radius.

Divide the circumference by π, or 3.14 for an estimation. The result is the circle's diameter.

Divide the diameter by 2.

There you go, you found the circle's radius.

16pi/pi = 16/2 = 8

V=4/3πr³

V=4/3π8³ = 2143.5733333333333333333333333333333333333333333333333333333333333...

Answer:

Yes, because the x's do not have more than one y.

Step-by-step explanation:

x y

0 0

5 10

6 12

10 20

(That's meant to be a table). Looking at the x and y table values, you can see that none of the x's have two y's. So, this relation is a function.

Answer:

74º

Step-by-step explanation:

Ray TV bisects ∠RTS, so ∠RTV=∠STV=(16x-6)º
We also know that ∠RTS=(26x+18)º
So, (16x-6)º+(16x-6)º=(26x+18)º
We don't need parenthesis, 16x-6+16x-6=26x+18
Combine like terms, 32x-12=26x+18
Add, 32x=26x+30
Subtract, 6x=30
Divide, x=5
∠RTV now is [16(5)-6]º=(80-6)º=74º

What is the quadratic in vertex form that has a vertex of (-1, 5)<br><br> Options in image

dimaraw [331]

Answer:

Third option

$y = (x+1) ^ 2 + 5$

Step-by-step explanation:

In this case we must write a quadratic equation in the vertex form.

We have the vertice. (-1, 5)

We know that the vertex form for a quadratic equation is:

$y = (x-h) ^ 2 + k$ .

Where (h, k) is the vertex.

So if the vertex is (-1, 5), the equation sought is:

$y = (x-(-1)) ^ 2 + 5$

$y = (x+1)) ^ 2 + 5$

Therefore the answer is the Third option.
