<u>Step-by-step explanation:</u>
Equation of parabola with focus at (0,-4) and directrix is .
We know that parabola is the locus of all the points such that the distance from fixed point on the parabola to fixed line directrix is the same.
The parabola is opening downwards.
Let any point on parabola is (x,y).
Distance from focus(0,-4) to (x,y) =
The answer to the question is D
Ok!

First find the volume of the patio by multiplying the three dimensions since it's rectangular. (25)(20)(1.5) = 750
Then take the amount per cubic foot 4.99 and multiply it by the volume 750 to get
$3742.50
