It would be “going up a steady rate through the origin”
Answer:
She bought 6 erasers.
Step-by-step explanation:
The slope is gonna be 3
the equation will be y=3x+20
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

You will take 75 divided by 6 and you will get 12.5 so you will round up to 13
