WILL GIVE MEDAL 1) Derive the equation of the parabola with a focus at (0, 1) and a directrix of y = −1. 2) Derive the equation of the parabola with a focus at (−2, 4) and a directrix of y = 6. Put the equation in standard form. 3) Derive the equation of the parabola with a focus at (−5, 5) and a directrix of y = -1. 4) Derive the equation of the parabola with a focus at (2, −1) and a directrix of y = −one half. 5) Derive the equation of the parabola with a focus at (−5, −5) and a directrix of y = 7.
the awenser is (2,3) and equal 5
.... that isn't even.. sigh. Anyone else?
you have 5 different questions. All of them are the same kind. I think you must study how to solve for them, not just get the answers.
Then I think someone should try to explain one of them so that I may understand them better ._.
do you know distance formula?
