Frank is trying to factor he has determined that one factor is (y + 9). what is the other factor?

Correct choice is D

Step-by-step explanation:

The quadratic polynomial can be factored as

where are roots of the polynomial.

If one of the factors is then one of the roots is -9.

By the Vieta formulas,

Then

From these equations ou can conclude that

Final answer is D. (y-3)

Step-by-step explanation:

Frank is trying to factor . He has determined that one factor is (y+9). Now we need to find the other factor.

So let's factor

Hence the other factor is (y-3).

1) is right

step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
