∆abc is translated 2 units down and 1 unit to the left. then it is rotated 90° clockwise about the origin to form ∆a′b′c′.
the coordinates of vertex a′ of ∆a′b′c′ are (-2,0), or (2,1), or (-1,-2), or (-2,1)
the coordinates of vertex b′ of ∆a′b′c′ are (1,-1), or (1,0), or (5,0), or (2,-3)
the coordinates of vertex c′ of ∆a′b′c′ are (-1,-1), or (3,0), or (-1,0), or (0,-3)

At a sand and gravel plant, sand is falling off a conveyor and onto a conical pile at a rate of 16 cubic feet per minute. the diameter of the base of the cone is approximately three times the altitude. at what rate is the height of the pile changing when the pile is 12 feet high? (hint: the formula for the volume of a cone is v = 1 3 πr2h.)
