A ball is dropped from a window at a height of 80 feet. The function below 3 points
represents the height (in feet) of the ball after x seconds. How long does it
take for the ball to hit the ground? (Think: what is ground level?) *
h =– 16x2 + 80

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?
