question 9 of 10
the distance from the green point on the parabola to the parabolas focus is

1. what is the distance from the green point to the directrix?

a. 11
b. 22
c. 9.5
d. 5.5

Explanation:

Step1: Recall the definition of a parabola

A parabola is the set of all points in a plane that are equidistant from a fixed point (the focus) and a fixed line (the directrix).

Step2: Apply the definition to the problem

Since the distance from the green point (a point on the parabola) to the focus is 11, by the definition of a parabola, the distance from this point to the directrix must also be 11.

Answer:

A. 11
