What is its center?

((left parenthesis

What is its radius?

If necessary, round your answer to two decimal places.

Step-by-step explanation:

General form of equation of a circle is expressed as where r is the radius of the circle and (a, b) is the center of the circle.

Given the equation of a circle to be , rewriting the equation to conform to the general equation above we have;

Comparing the equation given to the general equation above, a = 20, b = 0.05 and the radius of the circle will be 9. The center (a, b) will be (20, 0.05).

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
