12. Sure.

wht about u?

11th and its in algebra 2

sure, yr ques?

hang on let me type it all the way out

waiting.

ok lol dont be pushy

what is the standard equation for a porabola

y=ax^2+bx+c

http://www.mathwarehouse.com/geometry/parabola/standard-and-vertex-form.php

A parabola has an equation of x 2 + 4y = 0. What is the equation of the directrix

that 2 is a squared i only have more questions left including this one can u please help me

x^2 = -4ay is in standard form; where a is the measure from vertex to directix

since there are no values modifying the x and y; the vertex should be at the origin

but what does y equal

the parabola looks to open down so the directix would be above it

y = 1 should be the equation for the directix if I see it right

err... y = -1, might be better

the choices that it gives us are -1 then 0 , 4 2

ok

A parabola has an equation of 7x 2 = 28y. What is the coordinate of the focus?

4a = 28; a = 7 it is 7 away from the vertex in the direction that it opens up

let me rethink that ... the 7 is throwing me off :)

ok

is (0,1) an option for us?

yers the last two on my hw are true false and can u help me with those
