I need the correct format of solution step by step

Pls I need perfect score , :)

Do the graph on the answer sheet directly if not i will rate it

Activity 1: Write the standard equation of the ellipse with the given properties. 1. with Fi(0,3) and F2(0, -3), and has a major axis of length 10 2. with V1(-5, 0) and V1(5, 0). and passes through the point (2, 4) O Activity 2: For the given ellipse, find the (a) principal axis, (b) center. (c) vertices, (d) co- vertices, (e) foci, (f) length of the major axis, and (g) length of the minor axis, and (h) sketch the graph. x 2 1. 36 - =1 2. 25x2 + 9y?=225 25 | Page7 B.
