Find the equation for the parabola that has its vertex at the origin and has directrix at x=1/48
Oksana_A [137]

Answer:

The equation for a parabola with vertex at the origin and a directrix at x = 1/48 is x= \frac{1}{12}\cdot y^{2}.

Step-by-step explanation:

As directrix is a vertical line, the parabola must "horizontal" and increasing in the -x direction. Then, the standard equation for such geometric construction centered at (h, k) is:

x - h = 4\cdot p \cdot (y-k)^{2}

Where:

h, k - Horizontal and vertical components of the location of vertex with respect to origin, dimensionless.

p - Least distance of directrix with respect to vertex, dimensionless.

Since vertex is located at the origin and horizontal coordinate of the directrix, least distance of directrix is positive. That is:

p = x_{D} - x_{V}

p = \frac{1}{48}-0

p = \frac{1}{48}

Now, the equation for a parabola with vertex at the origin and a directrix at x = 1/48 is x= \frac{1}{12}\cdot y^{2}.
