Circle A with equation (X - 6)2 + (y - 7)2 = 81 is enlarged to match circle B with equation (X - 6)2 + (y – 7)2 = 4. Determine the scale factor needed for this
enlargement.
4/81
2/9
9/2
or 81/4

  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).

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)

2+2 obliviously is 4.
