C. The hot tub manual recommends filling the hot tub to 80% of its full capacity. How
much water should Rita put in the hot tub in order to follow the recommendation?

There isn't enough information try adding the max capacity amount and tell us what unit Rita is using. So we can't solve it.

Step-by-step explanation:

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

the answer is 0.071

good luck! : d
