Two points in the Cartesian plane are A (3.90 m, -7.30 m) and B (-1.20 m, 1.30 m). Find the distance between them (in m). 6.51 x m Find the polar coordinates of A and B. (Give the radial coordinates in meters such that r≥ 0, and the angles in radians counterclock from the +x-axis such that 0 < p ≤ 27. Do not include units in your answers.)
