The ball hits the ground when the height h(t) = 0 , so
-16t^2 + 80t = 0
-16t(t - 5) = 0
t- 5 = 0 or -16t^2 = 0 ( here t = 0 which corresponds to when ball is thrown)
t - 5 = 0 gives:-
t = 5 seconds (answer)
Step-by-step explanation:
b.) 8/7≈ 1.1
Final.) and then using the exponential decay formula, 18.1 will be left after
Answer:
2111.15
Step-by-step explanation:
A=2π*r*h+2π*r^2
You plug in your height and radius into the formula for surface area of cylinder
Answer: h=12.8in
a Base edge 15 in
V Volume 960 in³
Using the formula
V=a2h
3
Solving for h
h=3V
a2=3·960
152=12.8in
