1. A quadratic function fis defined by f(x) = (x - 7)(x + 3). a. Without graphing, identify the x-intercepts of the graph of f. ( , ) and ( , )

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 !

$12. that is my answer.

i believe it's a.

i'm not sure on this one, most likely correct.
