Answer:
9/10
Step-by-step explanation:
step 1
Compare the slopes



therefore
An experienced skier would like the 9/10 hill slope because it is steeper, while the 1/10 is a softer slope.
Answer:
Please check the explanation.
Step-by-step explanation:
Rebecca's ERROR
Rebecca wrongly used the formula to calculate the average rate of change from x = -1 to x = 3.
She should have used the correct formula to calculate the average rate of change from x = -1 to x = 3 which is:
Average rate = [f(3) - f(-1)] / [3 - (-1)]
But, she reversed the formula.
The correct solution
Considering the graph

Rebecca wants to find the average rate of change from x = -1 to x = 3.
so
at x₁ = -1

at x₂ = 3

Using the formula, we can determine the average rate of change from x = -1 to x = 3
Average rate = [f(3) - f(-1)] / [ x₂ - x₁]
![=\:\frac{\left[9\:-\:\frac{3}{2}\right]}{\left[3-\left(-1\right)\right]}](https://tex.z-dn.net/?f=%3D%5C%3A%5Cfrac%7B%5Cleft%5B9%5C%3A-%5C%3A%5Cfrac%7B3%7D%7B2%7D%5Cright%5D%7D%7B%5Cleft%5B3-%5Cleft%28-1%5Cright%29%5Cright%5D%7D)


Therefore, the average rate of change from x = -1 to x = 3 will be:
Average rate = 15/8
47, you would add the seventeen to the opposite side.
27/1053 = 1/39
1/39 ≈ <span>0.026</span>
