A golf ball is hit with a club from the ground on a flat surface. The height of the the ball, h(t), in feet, t seconds after it was hit can be modeled by the function h(t)=40t-16t^2

step-by-step explanation:

it's 15

step-by-step explanation:

what statement? is there an image?

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
