B. Write the equation of the ellipse with center at the origin that satisfies the given conditions. Draw the ellipse, its foci, and vertices. 11. The foci have coordinates (0, 4) and (0, -4), and a vertex at (0,-5). 12. An endpoint of a latus rectum is .V5 and the vertices have coordinates (0,3) and (0, -3). 13. The foci are on the x-axis, the x-intercepts are 12 and the y-intercepts are 1. 14. The foci are on the y-axis, the x-intercepts are 15 and the y-intercepts are 14. 15. The foci are on the x-axis, the length of the major axis is 12 and the length of the minor axis is 4 3. 16. The f
