Nathan is building a tree house. He needs wooden boards that are 16.45 feet, 7.3 feet, and 12.8 feet in length. What is the closest estimate of the total length he needs, in feet, to make sure he has enough wood for the tree house

Step-by-step explanation:

38 FEET

  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).

b
