A
180 - S = R
180 - 65 = 115
-6 because you take 10 away from 4 going into the negatives
Answer:
$20,000
Step-by-step explanation:
20,000 / 0.07 = 1400
For question 11, you essentially need to find when h(t) = 0, since that is when the height of the ball reaches 0 (ie touches the ground).
For question 12, it is asking for a maximum height, so you need to find when dh/dt = 0 and taking the second derivative to prove that there is maximum at t. That will find you the time at which the ball will hit a maximum height.
Rinse and repeat question 12 for question 13
