A stone arch in a bridge forms a parabola described by the equation y = a(x - h)2 + k, where y is the height in feet of the arch above the water, x is the horizontal distance from the left end of the arch, a is a constant, and (h, k) is the vertex of the parabola.

The answer would be y = - 0.071 (x - 13)^2 + 12.

Step-by-step explanation:

The next answer will be 15ft.

For edge the answers are:

y = -0.071(x - 13)^2 + 12

Then for the next question your answer is 15.
