Find the standard form of the equation of each of the following described ellipses. 5. An ellipse with vertices at (-6,3) and (2,3) and endpoints of the minor axis at (-2,4) and (-2,2). 6. An ellipse with vertices at (0, +10) and foci at (0, 18). 7. One calculation involving an ellipse is eccentricity, the measure of how close an ellipse is to being circular. By definition, eccentricity equals the ratio - , where a is the distance from the center to the vertices and c is the distance from the center to the foci. a. Calculate the eccentricity of the ellipse from problem #1. b. Calculate the eccentricity of the ellipse from problem #2. c. As distances, c and a are always positive. Furthermore, c
