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
WOW JIMMY. THATS A BIG . BIG. BIG. NUT SACK
Answer:
see explanation
Step-by-step explanation:
73.
18 = 3x
(divide both sides by 3 )
6 = x ( multiply both sides by )
6 = 3x [ × = 3 ]
divide both sides by 3
x = 2
74.
24 = 2x
( divide both sides by 2 )
12 = x ( multiply both sides by )
12 = 2x ( divide both sides by 2 )
x = 6
75.
9 × x = 18 ( divide both sides by 9 )
x = 2
76.
2 = x × 
( multiply both sides by )
2 = 4x ( divide both sides by 4 )
x = 
3/4x=728/3
x=728/3×4/3
x=32.556
