Answer:
Therefore the car takes 2 s to reach a minimum height from the ground before rising again.
Step-by-step explanation:
Given that a roller coaster ride reach a height of 80 feet.
The height above the ground of the roller coaster is modeled by the function
h(t)=10t²-40t+80
where t is measured in second.
h(t)=10t²-40t+80
Differentiating with respect to t
h'(t)= 10(2t)-40
⇒h'(t)=20t-40
To find the minimum height we set h'(t)=0
∴20t-40=0
⇒20t =40
⇒t=2
The height of the roller coaster minimum when t=2 s.
The minimum height of of the roller coaster is
h(2)= 10(2)²-40.2+80
=40-80+80
=40 feet.
Therefore the car takes 2 s to reach a minimum height from the ground before rising again.
Answer:
2,400,056
Step-by-step explanation:
Answer:
a) 1 minute and 12 seconds
b) .833 repeating
c) 25 minutes and 12 seconds
Step-by-step explanation:
A and B are simple so for C:
21 laps = 5 * 4 = 20, 6 * 4 = 24, 20 + 1 = 21, 24 + 1 minute and 12 seconds = 25 minutes and 12 seconds
12 * 5 = 60
If I messed up tell me I keep confusing myself.
