Brian is filling a conic container with water. He had the container half full. The radius of the container is 5 inches and the height is 20 inches. What is the current volume of the water? If Brian wants to transfer the water to a cylinder with a radius of 5 inches, and fill it completely, what height would the cylinder have to be?

1 , -4 , 2 + 5i , 2 - 5i

Step-by-step explanation:

g(x) = (x² + 3x - 4)(x² - 4x + 29)

x² + 3x - 4 = (x-1)(X+4)        x = 1     or x = -4

roots of x² - 4x + 29 = ax² + bx + c

x = (-b ± √b²-4ac) / 2a

x = (4 ± √16 - 4*29) / 2 = (4±√-100) / 2 = (4±10i)/2 = 2 ± 5i
