Answer:
t=3.5 seconds
Step-by-step explanation:
Given
h(t) = −16t^2 + 111t + 0
h'(t)= -32t + 111
Maximum height occurs when h(t) = 0 and the ball begins to fall
h(t)= -32t + 111=0
-32t + 111=0
-32t=-111
Divide both sides by -32
t=3.46872
Approximately, t=3.5 seconds
Recall,
Maximum height occurs when h(t) = 0
h(t)= -32t + 111=0
= -32(3.46872)+111
= -110.99904+111
= 0.00096 ft
I think you can do this way:
Volume = B*h where B is the area of the base.
B= 4 * 10 = 40
V= 40 * 15
V= 600 cm^3
Answer:
(17y/8) - 101 or (17y - 808) / 8
Step-by-step explanation:
Please enclose the fractional coefficient 1/8 inside paretheses:
(1/8)y + 17 + 2y - 118.
Now combine like terms. (1/8)y + 2y comes to (1/8)y + 16y/8 = (17/8)y.
We thus have (17/8)y + 17 - 118. Leaving (17/8)y alone, evaluate 17 - 118:
(17y/8) - 101
You could leave your answer in this form, or combine the terms using the LCD 8:
17y - 808
--------------
8
The answer is 3/10 ( hope this helps)
