The dashed-lined figure is a dilation image of efgh. is d(n, h) an enlargement or a reduction? what is the scale factor n of the dilation?

n = 3; enlargement

Step-by-step explanation:

The dashed-line figure is larger. That is the meaning of "enlargement."

Points on the dashed-line figure are 3 times the distance from point H as the corresponding point on the sold-line figure, so the scale factor is 3.

  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 would be a 24

step-by-step explanation:

c=2πr=2·π·3=24
