5) What is the equation in standard form of an ellipse centered at the origin and vertex (0,4) and focus (0,1)

after simplifying it i got: -36.25 as my answer. hope that !

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
