A diver in Acapulco jumps off a cliff. His height. y. in meters, as a function of 2, his distance from the cliff base in meters, is given by the quadratic function y = 100 – x2, for x > 0. A How high is the cliff from which the diver jumps?
B How far from the base of the cliff does the diver hit the water​

Figure abcd is a parallelogram. if point c lies on the line x = 2, what is the y-value of point c

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.)

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much
