Let m and c represent constante, with m nonzero. What is the equation of the line perpendicular to y=m(x+c) and would try the same y-intercept? A. Y=1/m(x+c)
B. Y=-1/m (x-m^2c)
C. Y=-1/m(x+c)
D. Y=1/m (x+m^2c)

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) .

What is the frequency of the sinusoidal graph?

Amountain climber starts a climb at an elevation of 453 feet above sea level at his first rest stop he has climbed 162 feet and by his second rest stop he has climbed another 207 feet its getting late in the day so the climber starts his way down if the climber desends 285 feet how much does he need to ascend or descend to return to the original starting point
