Can someone make sure that my answer is right?A.Width = (b – a)/nWidth = (24 – 0)/3Width = 8Trapezoid rule:8/2(f(0) + 2f(8) + 2f(16) f(24)4(0.5 + 3.4 + 3 + 0.5)4(7.4)29.6This definite integral should physically represent the total water usage for Seattle over this 24 hour period. Trapezoids approximate the total water usage as 29.6 million gallons/hr.B.0 < t < 8 is a “concave up” part of the interval. Therefore, the trapezoidal sum should overestimate the area.C.I had trouble writing out the integral as text, so my answer to Part C is attached as a second image.D.r’(12) = (r(14) – r(12))/(14 – 12)r’(12) = (1.4 – 1.3)/2r’(12) = 0.05
