If sinA = cosB, what is the relationship between A and B if A and B are both acute angled ?

5,600 x 10^3 = a) 560 b) 5,000,600 c) 5,600,000 d) 56,000

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .
