Find all solutions, one factor has been given.
f(x) =x3-3x2-25x+75; (X-5)

(x-3) (x+5) (x-5)

Step-by-step explanation:

given: x3-3x2-25x+75

we know that one factor is 5

so we can use that to get its next factors using Synthetic division

5 | 1 -3 -25 75

  |     5  10  -75

    1   2  -15  0

Know we have the next equation

x^2 +2x -15

and we know two number that can factor 3,5

(x-3) (x+5)

you need more information to answer this question

step-by-step explanation:

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
