You are an astronaut on the Moon. You hit a golf ball with your golf club. The height of the ball, h(t), in meters, after time, t, is modeled by the function h(t) = -0.81t^2 + 5t. What is the maximum height of the ball? How long is it in the air for?

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
