Question 206837: Could someone tell me if this is right?
Problem; What is the equation of the ellipse with foci at (0,-4) and (0,4) and the sum of its focal radii being 10?
My answer; 2a=10 a=5 (sum of focal radii)
(0+0/2, (4+4/2)= (0,4)
c=4 b^2=a^2-c^2=25-16=9
equation of the ellipse is;
(x-0)^2/25+(y-4)^2/9=1
