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) = 








Answer:
B. 4 squared
Step-by-step explanation:
You have to use PEMDAS. The first one is P for parenthesis, that is the first operation you have to do.
Step-by-step explanation:
To find coordinates, we need the equation of the line segment with restrictions. I think you meant to say “line segment” as lines go infinitely in 2 directions and could not be broken up into ratios. Let’s say your segment is 24 feet long. You could then label AB as 5x and BC as x since that is a ratio of 5:1 …………We’d then have an equation
5x + x = 24 … or 6x = 24…..or x = 4 which would make AB = 20 and BC = 4…but this would not give us coordinates of points.
