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:
$18
Step-by-step explanation:
I did the following expressions:
1,350 / 75 = 18
1,080 / 60 = 18
9/12 in simplest form would be 3/4 because you divide bothe 9 and 12 dived by three because what you do to the denominator you do to the nominator so after you divide 9/12 by 3 you would have 3/4 which 3/4 is 9/12 in simplest form
Answer:
P could be any number if (4p+12) doesn't equal to number
