Frida applied the steps below to find the product of (–1.2)(–9.4). Step 1: (–1.2)(–9.4) = (–9.4)(–1.2) Step 2: = (–9.4)(–1) + (–9.4)(–0.2) Step 3: = (9.4) + (1.88) Step 4: = 11.28 Which step shows where she applied the property that states multiplying two negative numbers will always yield a positive number? Step 1 Step 2 Step 3 Step 4

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.)
