Question

A bridge is built in the shape of a semielliptical arch. The bridge has a span of 120 ft and a maximum height of 25 ft. Find an equation for the ellipse and then find the height of the arch at distances of 10, 30, and 50 ft from the center.

For the equation I got this:
(x^2/60^2)+(y^2/25^2)=1

Answer 1

How would I do 10 feet?

Answer 2

just find the value of y for x=10 from the equation

Answer 3

Ok thanks
