Find a function
that will accumulate the power used over time . Be sure that . What is its relationship to ?
Notice that lower-case,
, is a rate function.
to find the total electrical energy used during this month.
Assume the month has
'Total electrical consumption' is another way to say 'accumulated power.'
Sketch a graph of
for this -day period.
Make sure that this graph agrees with your function for
Calculate the average power used in kilowatts for this month. Did your answer match that in problem 6-151? How is this rate represented geometrically in the graph?
