What is the equation of a parabola with vertex (0, 0) and directrix x = -3.
miv72 [106K]

Answer:

{y}^{2}= 12x

Step-by-step explanation:

The standard equation of a parabola with vertex at the origin and and directix x=-p is of the form

{y}^{2} =  4{p}x

Where p is simplify the distance from the origin to the directrix.

That is

p =  3

{y}^{2}  = 4 \times 3x

This simplifies to

{y}^{2}= 12x

What is the value of B - A as a fraction?
umka21 [38]
Answer:
A = 1/4
B = 3/4

step-by-step explanation:
the middle should be 1/2 because the middle between 0 and 1 is 1/2
A and B are both in the middle of the sides
therefore A would be closer to 0 so 1/4
and B would be closer to 1 so 3/4
