Answer:
Average rate of change for the function
over the interval -1<x<1 is -1
Step-by-step explanation:
We need to find average rate of change of f over the interval -1 < x < 1
The function given is: 
The formula used to find average rate of change is:

We have, a = -1 and b = 1
Finding f(b) when b=1

Now, finding f(a), when a= -1

Now, putting values and finding average rate of change

So, average rate of change for the function
over the interval -1<x<1 is -1
Answer:
20 feet
Step-by-step explanation:
Lance the alien is 5 feet tall. His shadow is 8 feet long. At the same time of day, a tree's shadow is 32 feet long. What is the height of the tree?
We solve this using proportion of
Height/ Shadow
= 5/8 = x/32
Cross Multiply
8x = 5 × 32
x = 5 × 32/8
x = 20 feet
The height of the tree is 20 feet
