Question

A general formula for a parabola is x2=4py. What is the value of p in the equation x2=12y? p=3 p=4 p=6 p=12

Answer 1

A general formula for a parabola is x2=4py.

What is the value of p in the equation x2=12y?

A) P=3

Answer 2

p = 3

Explanation:

The given equation of parabola

`x^2 = 12y`

The standard parabola equation

`x^2 = 4py`

Now, all we need to do is compare or equate the above two equations to find the value of p

`4py =12y\\p =3`

Therefore, the value of p = 3 in the equation asked
