The figure shows the power usage in megawatts for one day for a large university campus. The daily power consumption for the campus is measured in megawatt-hours and is found by calculating the area of the region between the graph and the horizontal axis. m(t) megawatts 40 35 30 25 t hours since 6 12 18 24 midnight (a) Estimate the daily power consumption, using eight left rectangles. (Round your answer to one decimal place.) megawatt-hours (b) Estimate the daily power consumption, using eight right rectangles. (Round your answer to one decimal place.) megawatt-hours ×
