1. Find an equation of an ellipse with vertices at points (-2, 5) and (-2, -3), containing point (0, 3).(adsbygoogle = window.adsbygoogle || []).push({});

2. A bridge is to be constructed across a river that is 200 feet wide. The arch of the bridge is to be semielliptical and must be constructed so that a ship less than 50 feet wide and 30 feet high can pass safely through the arch.

(a) Find an equation in standard form of an ellipse that encompasses the semielliptical arch of the bridge.

(b) Determine the exact height of the semielliptical arch in the middle of the bridge.

I have a feeling these aren't as complicated as I'm trying to make them...usually arent. I hate ellipses. Maybe if I understood them better it would help... Thanks--Jennifer
