Use the Distance Formula to write an equation of the parabola with focus F (0, 4) and directrix y = -4.

Respuesta :

Kaitou

Step-by-step explanation:

focus=(0,4)

Direcrtrix,y=-4

p=4

vertex=(0,0)

Open upward

(x-h)²=4p(y-k)

(x-0)²=4(4)(y-0)

(x-0)²=16(y-0)

Answer:

1/16x^2

Step-by-step explanation:

This is an extremely easy question. My friend told me this and my assignment was 20x easier.

So basically, you take y=-4. Flip the sign of Y, in this case, it would be 4. Now multiply 4 by 4.

4x4 = 16

put 1 over 16. 1/16 then add the x squared. And boom, you have your answer!
