Accreditation is a process in which school standards are evaluated by an accreditation agency. In the United States, this process is not completed by the federal government, but by states or private companies with varying rules and standards. Different groups promote accreditation for homeschoolers.
The circle is the simplest and best known conic section. As a conic section, the circle is the intersection of a plane perpendicular to the cone's axis. The geometric definition of a circle is the locus of all points a constant distance r {\displaystyle r} from a point ( h , k ) {\displaystyle (h,k)} and forming the circumference (C).
A conic section(or simply conic) can be described as the intersection of a plane. and a double-napped cone. Notice from Figure B.1 that in the formation of the four. basic conics, the intersecting plane does not pass through the vertex of the cone. When. the plane does pass through the vertex, the resulting figure is a degenerate conic,as.
