Find the standard form of the equation of the parabola with a focus at (0, -8) and a directrix at y = 8.

The standard form of the equation of the parabola is .

Step-by-step explanation:

The general form of a parabola is

Where, (h,k) is vertex, (h,k+p) is focus and y=k-p is directrix.

Focus of the parabola is (0, -8).

       .... (1)

Directrix of the parabola is

          .... (2)

On adding (1) and (2) we get

Put this value in equation (1).

The value of p is -8.

Substituent h=0,k=0 and p=-8 in general form of parabola.

Divide both sides by -32.

Therefore the standard form of the equation of the parabola is .

step-by-step explanation:

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
