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

<h3>Function</h3>

Function relates input to output. Therefore,

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
