The answer probably is $127 if you add $49+$79=$127
For question 11, you essentially need to find when h(t) = 0, since that is when the height of the ball reaches 0 (ie touches the ground).
For question 12, it is asking for a maximum height, so you need to find when dh/dt = 0 and taking the second derivative to prove that there is maximum at t. That will find you the time at which the ball will hit a maximum height.
Rinse and repeat question 12 for question 13
Answer:
Step-by-step explanation:
To solve for 
, first multiply by on both sides to get this:
Now, you can factor out an from the right side to get this:
Now divide by 
in order to solve for and you get:
The answer is B. 247.50$, because the 65% of 150$ is 97.5, so 150 + 97,5 = 247.5$.
