Question 13

Find the equation of the lines joining the vertex of the parabola y2 = 6x to the point on it which have abscissa 24

Solution 13

Question 14

Find the coordinates of points on the parabola y2 = 8x whose focal distance is 4

Solution 14

In given parabola

a=2

Given focal distance=a+x=4, so x=2

So points are (2, 4) and (2, -4)

Question 15

Find the length  of the lines segment joining the vertex of the parabola y2 = 4ax and a point on the parabola where the line-segment makes an angle to the axis

Solution 15

Question 16

If the points (0, 4) and (0, 2) are respectively the vertex and focus of a parabola, then find the equation of the parabola.

Solution 16

Question 17

If the line y = mx + 1 is tangent to the parabola y2 = 4x, then find the value of m.
