Ineed on two questions! 1. write the equation of an ellipse with vertices (10, 0) and (-10, 0) and co-vertices (0, 2) and (0, -2). second question in below.

1)

Explanation:

The equation of an ellipse is: ; where (h, k) is the center, "a" is the x-radius, and "b" is the y-radius.

               Center                        Radius

x-axis:   (10 + -10)/2 = 0            10 - 0 = 10

y-axis:   (2 + -2)/2  = 0               2 - 0 = 2

Now, input the values into the equation:

2)

Explanation:

Vertices are: (0, 1) and (0, -5) ------> x-values are the same, y = 1, -5

Covertices are: (-1, -2) and (1, -2) ----> y-values are the same, x = -1, 1

               Center                        Radius

x-axis:   (-1 + 1)/2 = 0                  1 - 0 = 1

y-axis:   (1 + -5)/2  = -2               1 - (-2) = 3

Now, input the values into the equation:
