The equation of the ellipse having vertices at ($$\pm$$ 5, 0) and foci ($$\pm$$ 4, 0) is
The latus rectum of an ellipse is equal to one-half of its minor axis. The eccentricity of the ellipse is
The coordinates of the focus of the parabola described parametrically by x = 5t2 + 2, y = 10t + 4 are
If t1 and t2 be the parameters of the end points of a focal chord for the parabola y2 = 4ax, then which one is true?
