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:
h=3
Step-by-step explanation:
h/10 -6 =24
+6 to each side
h/10=30
divide each side by 10
h=3
Explanation
when you have two lines in a graph, the solution is the point where the line intersect each other, so to solve this we need to find that point
so, the answer is
