The upside to a prorated warranty is that many of the warranties now include benefits that provide 100% guarantees for the first 5 or 10 years. This warranty is contrary to non-prorated warranties that requires manufacturers to take full responsibility until the warranty has been entirely served.
Locus Theorem 3: The locus of points equidistant from two points, P and Q, is the perpendicular bisector of the line segment determined by the two points. Locus Theorem 4: The locus of points equidistant from two parallel lines, l1 and l2, is a line parallel to both l1 and l2 and midway between them. Locus Theorem 5: The locus of points equidistant from two intersecting lines, l1 and l2, is a pair of bisectors that bisect the angles formed by l1 and l2.
where a is some constant. Also suppose that the focus is given by (x,y) = (b,c). The vertex is then, by definition and inspection, located at: Now let's examine the distance between some point in the x-y plane (x*,y*) and focus and directrix. The distance between the point and the focus is given by the distance formula:
