an orbitof a of a satellite around a planet is an ellipse, with the planet at one focus on this ellipse. the distance of the satellite from this star varies from 300,000 km to 500,000 km, attained when the satelite is at each of th two vertices. find the equation of this ellipse, if its center is at the origin, and the vertices are on the x-axis. assume all units are in 100,000 km. make an illustration(using cartesian plane) depicting the situation.
