Monique is punting a football and the height the ball travels is a function of time. The function h(s)=−s2+10s+3 gives the height of the ball, h(s) , given the number of seconds, s , that the ball has been in the air. After flying through the air for 7.5 seconds, what is the height of the ball? Find h(7.5) .(1 point)

Answer 1

To find the height of the ball after 7.5 seconds, we can substitute 7.5 for s in the function h(s) = -s^2 + 10s + 3.

h(7.5) = -(7.5)^2 + 10(7.5) + 3
= -56.25 + 75 + 3
= 21.75

So, the height of the ball after 7.5 seconds is 21.75. Therefore, the correct answer is 21.75.
