On a photograph of a triangular piece of land, the lengths of the three sides are 12 cm, 15 cm, and 21 cm respectively. the shortest side of the actual piece of land is 100m long. find the lengths of the other two sides.

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.)

What does the sign of the slope tell you about a line?
