The concept of perpendicularity can be applied to planes. if a line, line segment, or ray is perpendicular to a plane, it is
perpendicular to every line, line segment, or ray in that plane at the point of intersection. in the figure below, mn b find all
pairs of perpendicular lines.

Fred and gene are hang gliding. fred is 700 feet above the ground and descending at 15 ft/s. gene is decending as shown in the table. interpret the rates of change and initial values of the linear functions in terms of the situations they model. show all work. freds equation is f(x)=-15x+700. ( genes is the table attached)
