Write an equation for a parabola in which the set of all points in the plane are equidistant from the focus and line. F(–2, 0);
1 answer:
The line is called the directrix. Here we have a vertical directrix, so a parabola sideways from usual.
Geometry is best done with squared distances. The squared distance from an arbitrary point (x,y) to the vertical line x=2 is
We equate that to the squared distance of (x,y) to the focus (-2,0):
We could call that done. A more standard form might be

Answer:
T F T T.
Step-by-step explanation:
Let p and q be two statement
When the value of p is true and the value of q is true then the value of is true.
When the value of p is true and the value of q is false then the value of is true.
When the value p is false and the value of q is true then the value of is false.
When the value of p is false and the value of q is false then the value of is true.
Hence, the value of is false when q is true and p is false.
