Find the result of equation of the ellipse whose foci are at (0 , -5) and (0 , 5) and the length of its major axis is 14.  Choose the correct choice.
A) 5  B) 4  C) 3  D) 2  E) 1
From the coordinates of the foci, c = 5 and the major axis is the y axis. From the length of the major axis, we obtain a = 7. Also b 2 = a 2 - c 2 = 24.   The equation of the ellipse is given by   x 2 / 24 + y 2 / 49 = 1   correct answer is 1) 1
