Hey guys, I am in dire need of some homework for my pre-calc class. Thanks in advance.

A satellite dish has a 24 foot focal length. At what distance is the receiver at from the vertex of the parabola at (0,0): what is the equation of this parabola?

Focus distance?
Equation?

vertex (h,k)=(0,0)
focus is @ focual length: (0,24)
now do the eqn like here: http://www.purplemath.com/modules/parabola4.htm
