Question

​Find the perpendicular distance from (4, -5) to the line 2x - 4y - 23 = 0. help me with this question

Answer 1

Answer:

Hey mate here is your answer...

Step-by-step explanation:

General normal equation of parabola y

2

=4ax is xt+y=2at+at

3

General point on the parabola is (at

2

,2at).

For end of latus rectum t=1,−1.

Substitute t=1,−1 in the given normal equations.

x+y=3

x−y=3

Since the above two equations are tangents to the given circle, perpendicular distance from center to any of these lines is radius(r).

On finding the perpendicular distance from center we get value of r

2

is 2.
