-3
4
-4
The equation of normal at the point ( 0 , 3) of the ellipse 9x2 + 5y2 = 45 is.
y - 3 = 0
y + 3 = 0
x - axis

The length of latus rectum of parabola y2 = 12x is
12
1
The equation of the parabola with its vertex at (1 , 1) and focus (3 , 1) is
(x - 1)2 = 8 (y - 1)
(y - 1)2 = 8 ( x - 3)
(y - 1)2 = 8 (x - 1)
(x - 3)2 = 8 ( y - 1)

(0 , 0)
(3, 0)
(0 , 3/2)
(0 , 5)
The directrix of the parabola y2 = 16x is
x = - 4
y = - 4
x = 4
y = 4

(2 , 1)
(1 , -2)
(-1, 2)
(1 , 2)
If the major axis of an ellipse is 3 times its minor axis, then its eccentricity is
2/3
√2/3
2√2/3
4√2/3
The equation of the director circle of the hyperbola is
x2 + y2 = 4
x2 + y2 = 12
x2 + y2 = 16
x2 + y2 = 20
