Electricity is consumed between the hours of midnight (t = 0) and 6 a.m. (t = 6). Selected values of the rate of consumption are shown in the table below, with t measured in hours past midnight, and R(t) measured in KW per hour. Use 4 trapezoids to estimate the total amount of electricity to the nearest KW consumed between midnight and 6 a.m.
t (hours) 0 1 2 5 6
R(t) KW/hr 400 200 350 200 150

Best ResponseYou've already chosen the best response.0this is what iv got Left point sum (400 + 200 + 1050 + 200) = 1850 Right point sum (200 + 350 + 600 + 150) = 1300 Average sum (1850  1300)/2 = 1575
