Somewhere in a far far away galaxy, the three- point line of the basketball court is parabolic. The two ends of the line, which is aligned with the basketball ring, are 6 m apart. The vertex of the parabola is directly opposite the ring and is 10 m away from the ring. Michael Jokedarn Research foundation has found out that the best shooting spot is located at the focus of the parabola. How far is this point from the ring?
