an ellipse has a vertex at (5,0), a co-vertex at (0, -3), and a center at the origin. which is the equation of the ellipse in standard form?

Step-by-step explanation:

her center , and is the horizontal radius, and is the vertical radius.

So the center is .

because (5,0) has a distance of 5 from (0,0).

because (0,-3) has a distance of 3 from (0,0).

So the equation is:

Simplifying a bit:

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
