Thanks BuT! Ok--How do I go about finding the equation of only the top part of the ellipse-the positive y part. I understand how to come at the equation for the entire thing but I just need the top. I figure it has something to do with solving for y but I don't know what to do with that even if...
1. Find an equation of an ellipse with vertices at points (-2, 5) and (-2, -3), containing point (0, 3).
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...
I was wondering if anyone could help me with this problem
A circle is tanget to line 2x-y+1=0, at point (2, 5), and the center point is on line, x+y=9. Determine the equation (in general form) of the circle.
Normally I can do this sort of problem but I am having a hard time with this one...
