The center of a circle is at the origin on a coordinate grid. the vertex of a parabola that opens upward is at (0,9). if the circle intersects the parabola at the parabola's vertex, which statement must be true? a. the maximum number of solutions is one b. the maximum solutions is three c. the circle has a radius equal to 3 d. that circle as a radius less than 9

A. the maximum number of solutions is one

Since the circle and parabola intersect at (0, 9 ) this is the only solution there is, as the parabola opens upward away from the circle.

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
