Orange War took it away.

Answer 3

i can't see the question bec of ????????????????????????????????????/

Answer 4

Derive the equation of the parabola with a focus at (2, -1) and a directrix of y = -1/2.

Answer 5

Hewo?

Answer 6

i'm sorry i don't know
i'm still learning
2+2
5+5
33=33

Answer 7

Derive the equation of the parabola with a focus at (2, −1) and a directrix of y = −one half.

f(x) = −(x + 2)2 -3/4
f(x) = (x + 2)2 + 3/4
f(x) = −(x - 2)2 + 3/4
f(x) = −(x - 2)2 - 3/4

If this helps you any better :)
Also i believe this is A but not sure D:

Answer 8

I like to do it the long way:
The distance from (x,y) to (2,-1) is suppose to be the same distance as (x,y) is to (x,-1/2)
That is, the distance from a point on the parabola to the focus is the same as the distance from that same point on the parabola to the directrix

Answer 9

So I would find both distances
then equate them

Answer 10

then square both sides
then there might be just a little math left

Answer 11

umm
How do you do that?
Im just learning this and they really didnt teach me much @freckles

Answer 12

do you know how to find the distance between two points?
