Identify the equation of the circle that has its center at (9, 12) and passes through the origin.

The circle has center at (9, 12) and passes through the origin.

Equation of the circle in center and radius form is given by

where r is the radius and center at (h,k)

Now substitute the value of the center we get

As it passes through the origin so we can write

Hence the equation of the circle is

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
