Figure 7 shows the rate R(t) of natural gas consumption (in billions of cubic feet per day) in the mid-Atlantic states (New York, New Jersey, Pennsylvania). Express the total quantity of natural gas consumed in 2009 as an integral (with respect to time t in days). Then estimate this quantity, given the following monthly values of R(t): 3.18, 2.86, 2.39, 1.49, 1.08, 0.80, 1.01, 0.89, 0.89, 1.20, 1.64, 2.52 Keep in mind that the number of days in a month varies with the month. 1 2 3 J FMAM J J ASOND Natural gas consumption (109 3 ft /day) FIGURE 7 Natural gas consumption in 2009 in the mid-Atlantic states
