When you make the circle bigger or smaller, which number of the standard equation for the circle centered at the origin changes? A. the x coordinate
B. the y coordinate
C. the radius
D. the origin​

C

Step-by-step explanation:

Its is the radius of the equation for the circle entered I hope this helps

because its not ur topic and its not for is for homework not that.

  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).
