Given a pendulum with horizontal displacement given by d=1.3cos((3pi/4)(t), answer questions 9 - 12: Find the maximum displacement for the equilibrium position.

Find the frequency and length of the pendulum.

Calculate the horizontal displacement when seconds.

Determine the least positive value of t for which .

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) .
