Think About the Process Suppose APQR is rotated 270° about the origin, (0,0). Find the coordinates of p', Q', and R'. Then sketch AP'Q'R'.

Complete the equation of the line through (−10,3) and (−8,−8). use exact numbers.

What is the slope of the line that contains the points (-2,1) and (0,-3)

Apinhole camera is made out of a light-tight box with a piece of film attached to one side and pinhole on the opposite side. the optimum diameter d(in millimeters) of the pinhole can be modeled by d=1.9[ (5.5 x 10^-4) l) ] ^1/2, where l is the length of the camera box (in millimeters). what is the optimum diameter for a pinhole camera if the camera box has a length of 10 centimeters
