For the parabola y^2 = 8x, find the coordinates of a point whose focal distance is 4 units.

Show answer

(2, 4) and (2, -4)

The parabola y^2 = 8x is y^2 = 4ax, so a = 2. Its focus is (2, 0). Let the point be (x, y). Focal distance 4 gives (x - 2)^2 + y^2 = 16. Since the point lies on the parabola, y^2 = 8x. Substituting gives (x - 2)^2 + 8x = 16, so x^2 + 4x - 12 = 0, giving x = 2 or -6. Only x = 2 fits the parabola. Then y^2 = 16, so y = ±4.

Find the directrix of the parabola whose vertex is (-3, 0) and directrix is x + 5 = 0?

Show answer

x = -5

The directrix is already given by x + 5 = 0, which simplifies to x = -5.

For the hyperbola x^2/16 - y^2/9 = 1, find its eccentricity.

Show answer

5/4

Here a^2 = 16 and b^2 = 9. So c = √(a^2 + b^2) = √(25) = 5. Then e = c/a = 5/4.

Find the length of the latus rectum of the hyperbola x^2/36 - y^2/64 = 1.

Show answer

64/3

Here a = 6 and b = 8. The latus rectum length is 2b^2/a = 2(64)/6 = 64/3.
