Answer:
h = 9 feet.
Step-by-step explanation:
The height at the top of a roller coaster hill is 10 times the height h feet of the starting point. The height decreases 100 feet from the top to the bottom of the hill. The height at the bottom of the hill is -10 feet.
Therefore, there is a zero elevation point between the starting point at h height and the bottom of the hill which is at - 10 feet from the zero elevation point.
Now, the elevation of the top of the hill from the zero elevation point is (100 - 10) = 90 feet.
Therefore, 10h = 90
⇒ h = 9 feet. (Answer)
Answer:
point N
Step-by-step explanation:
the closest perfect square to 82 is 81 which is 9
the closest perfect square to 99 is 100 which is 10
possible choices are N, P, or Q
since 81 is very close to 82, the answer is going to be very close to 9
answer would be point N
Angle 1 - 72 degrees
Angle 2 - 36 degrees
Angle 3 - 16 degrees
Angle 4 - 144 degrees
