Find the rectangular coordinates of the point that has polar coordinates (2, -5pi/3)

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) .

Given f(x)= 9x+1 and g(x)=x^3, choose the expression (f*g)(x)

In the diagram, gef and hef are congruent. what is the value of x
