Monique is punting a football and the height the ball travels is a function of time. The function h(s) = - s ^ 2 + 10s + 3 gives the height of the ball, h (s )given the number of seconds, , that the ball has been the air. After flying through the air for 7.5 seconds, what is the height of the ball? Find h (7.5). point) 24 134 25 21.5 21,75
To find h(7.5), you will substitute 7.5 for s in the equation h(s) = - s^2 + 10s + 3.
h(7.5) = - (7.5)^2 + 10(7.5) + 3
h(7.5) = - 56.25 + 75 + 3
h(7.5) = 21.75
So, the height of the ball after flying through the air for 7.5 seconds is 21.75.
