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

❖ A composite number is 27. 27 is composite because there are more numbers than 1 and itself that can be multiplied to create 27. The two other numbers to make 27 are 3 x 9. All the other answer choices are prime numbers because no other numbers besides 1 and itself can be multiplied to make that number.

A dozen is 12 and since 4 is a multiple of 12, I did 12 divided by 4 which is three. So i did 3.50 multiplied by 3 and the answer is 10.50
