A solar farm records its power output (in kilowatt-hours) once every hour from 10 a.m. to 2 p.m. The data are shown below, where t is hours after 10 a.m. and P(t) is the power generated in that hour.
Use the trapezoidal rule with an interval width of 1 to estimate the total energy generated between 10 a.m. and 2 p.m..
To earn a crown, get your answer ready before you reveal the options!
A high-precision meter later shows the true total was 325 kWh.
Calculate the percentage error of your estimate from part (a).
