To find the p-value for a parabola given its focus and directrix, first identify the coordinates of the focus (F) and the equation of the directrix (a line). The p-value represents the distance from the vertex of the parabola to the focus (or the vertex to the directrix), which is half the distance between them. Calculate this distance using the formula for distance between a point and a line, or by measuring the distance from the vertex to either the focus or the directrix. The p-value is then the absolute value of this distance.

To find the image of point C after a 180-degree counterclockwise rotation about point P, you first identify the coordinates of both points. Then, you reflect point C across point P, effectively moving it to the opposite side of P at an equal distance. The resulting image will be directly opposite C in relation to P, forming a straight line through P.
P = the distance around a figure. A = the surface it takes up.
It depends on how complicated you want to make it. The generally accepted answer would be to start at one point, and make a line to the next (a straight line). That's gonna be the answer, say, your teacher might want (sorry if you're an adult :p). The technical answer? Drill a hole through the globe from one point to the other, and your shortest distance would be the straight line. Einstein's answer? A geodesic. Look it up :p

Given a point P = (a,b) and slope m, the equation of a line through P with slope m is (y-b) = m(x-a)
The hyperbolic parallel postulate states that given a line L and a point P, not on the line, there are at least two distinct lines through P that do not intersect L.The negation is that given a line L and a point P, not on the line, there is at most one line through P that does not intersect L.The negation includes the case where there is exactly one such line - which is the Euclidean space.
true
If (p, q) is any point on the line, then the point slope equation is: (y - q)/(x - p) = 2 or (y - q) = 2*(x - p)
