One day at football practice, Darrell, the kicker, punted the ball so that its height in feet above the ground was given by the following function, where t is the number of seconds since the ball was punted.

[tex]h(t)=-16t^{2} +75[/tex]

When will the football be 81 feet high?

Sagot :

When the football is 81 feet high, it will be √  3 / 8 seconds

Function

Function relates input to output. Therefore,

  • h(t)  = - 16t² + 75

Therefore,

t = number of seconds

h(t) = - 16t² + 75

h(t) = 81 ft

Therefore,

81 = - 16t² + 75

- 16t²  = 81 - 75

- 16t²  = 6

divide both sides by -16

t² = 6 / -16

t² = - 3 / 8

square root both sides

t = √  3 / 8 seconds
