Suppose that a household's monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundre graphed, the function gives a line with a slope of 1.35. See the figure below. If the monthly cost for 14 HCF is $44.87, what is the monthly cost for 8 HCF? Monthly cost (in dollars) 44.87 Water usage (in HCF) $0 X 3

Español Suppose that the credit remaining on a phone card (in dollars) is a linear function of the total calling time (in minutes). When graphed, the function gives a line with a slope of - 0.12. See the figure below. There is $32.40 in credit remaining on the card after 20 minutes of calls. How much credit will there be after 33 minutes of calls? Aa Remaining credit 32.40 ? (in dollars) 20 Calling time (in minutes)

The air pressure in the cabin of fighter jet decreases as the plane ascends. Air Pressure in pounds per Altitude in 10,000 of feet square inch 1 10.200 2 6.375 3.984 4 2.490 A. The change is linear. The constant rate of change is about -3.825 . B. The change is linear. The constant rate of change is 0.0003825. C. The change is exponential. The common ratio is about 0.625. D. The change is exponential. The common ratio is about 1.6. Interpretation: A. The air pressure decreases by about 37.5% every 10,000 feet of altitude. B.
