Which of the following is a polynomial with roots 5, 4i, and −4i?
a.) f(x) = x3 − 5x2 + 20x − 16
b.) f(x) = x3 − 5x2 + 16x − 80
c.) f(x) = x3 − 20x2 + 5x − 16
d.) f(x) = x3 − 16x2 + 80x − 5

Solve the inequality, then identify the graph of the solution. 2x – 1 > x + 2

He concluded that a heavier object dropped from the same height as a lighter object will land

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400
