Use the LS = RS check to make sure you were correct for 1b. 1b = x+3 / 4 = 2

(x + 3/ 4) x (4) = (2) x (4)

x + 3 = 8

x + 3 - 3 = 8 - 3

x = 5

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.)

The width of a rectangle is 20 units. can the perimeter p of the rectangle be 64 units when its length x is 11 units? no, because p = 2x + 2(20) no, because p ≠ 2x + 2(20) yes, because p ≠ 2x + 2(20) yes, because p = 2x + 2(20)

If f(x) = -5x + 1 and g(x) = x3, what is (gºf)(0)? enter the correct answer
