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

Answer: 2x+4=10
Step-by-step explanation:
because each notebook would cost $3 so 2 x 3 = 6 +4=10
40,023,032 = 40,000,000 + 20,000 + 3,000 + 30 + 2
Irst you multiply 2 both sides
2A=h(a+b)
then divide each side by a+b
2A/(a+b)=h
that's the simplified equation
Yeah you did it right but good job!
