A. Determine the equation the ellipse given by the center, foci, and vertices. 1. What is the equation of an ellipse with foci at the points (5, 4 ) and (13 ,4) with vertices at the points (4 , 4) and (14 ,4)? 2. What is the equation of an ellipse with foci at the points ( 2 , 2 ) and ( 14, 2 ) and with vertices at the points (- 2,2 ) and ( 18 ,2) ? 3. What is the equation of an ellipse with vertices at ( +10 , 0) and foci at ( 18 , 0 )
