Write an equation for the ellipse that satisfies the set of conditions.
endpoint of major axis at ( 0, 10) and (0, 10) foci at (0, 8) and (08)
Please help, I really don't understand how to do this

an ellipse with center at (h,k) and semiaxes a and b is
(xh)^2/a^2 + (yk)^2/b^2 = 1
the foci are at c where a^2 = b^2 + c^2 and lie on the major axis.
you thus have
a = 10
c = 8
so, b = 6
It appears that the center is at (0,0), so
x^2/100 + y^2/36 = 1
