Average rate of change = [H(100) - H(80)] / (100 - 80)
H(100) = 0.003(100)^2 + 0.07(100) - 0.027 = 0.003(10000) + 0.07(100) - 0.027 = 30 + 7 - 0.027 = 36.973
H(80) = 0.003(80)^2 + 0.07(80) - 0.027 = 0.003(6400) + 0.07(80) - 0.027 = 19.2 + 5.6 - 0.027 = 24.773
Average rate of change = (36.973 - 24.773)/(100 - 80) = 12.2/20 = 0.61
Answer: B
Answer:
5 hours
Step-by-step explanation:
4/5 is 20 of 25, so there are 5 hours left which is your answer!
To find the exterior angle measure we would use the following formula:

A regular hexagon has 6 sides so we divide:
360/6 which equals 60
So our final answer would be A. 60
The answer is b, f(x) = (x) + 1.
