In the diagram below, OM is the radius of the large circle and also the diameter of the smaller circle. Chord EM of the larger circle cuts the smaller circle at N.
If EM=(2x²-2)units and ON= 2x units.
Express giving reasons the length of the radius of the larger circle in terms of X ​

Three students, javier, sam, and corrine, participated in a fundraiser where people donated a certain amount of money per lap that the student ran. each student also had some initial donations that were collected before the run. the equations that represent each student's total donation, y, based on the number of laps ran, x, is shown below. match each equation with the correct rate of change for that student.
