Below are sample questions representative of the exercises included on this worksheet and related Pre CAL.186 Accumulation as Area and Riemann Sums skill assessments:

Problem 1Difficulty: Mastery
Use the graph of q'(t), a rate in liters per hour. The partition is P = {0, 1, 3, 4, 7}. The sample rectangle heights are 6, -4, 2, and -1 on the four subintervals. What is the approximate accumulated change and interpretation?
A-3 liters; the quantity decreases by about 3 liters.
B3 liters per hour; the final rate is 3.
C21 liters; all rectangle heights should be made positive.
D-9 liters; the interval widths are all 1 hour.
Solution & Explanation:Use widths 1, 2, 1, and 3: 1(6) + 2(-4) + 1(2) + 3(-1) = -3 liters. The quantity decreases by about 3 liters.
Problem 2Difficulty: Mastery
A service earns money at rates measured in dollars per hour, but time is listed in minutes. t (minutes): 0, 20, 50; rate: 60, 90, 120. Use a right endpoint Riemann sum on [0, 50]. Which estimate is correct?
A90 dollars; use (20/60)(90) + (30/60)(120).
B6900 dollars; use 20(90) + 30(120).
C150 dollars; use 90 + 120 - 60.
D70 dollars; use (20/60)(120) + (30/60)(90).
Solution & Explanation:The widths are 20/60 hour and 30/60 hour. A right sum is (20/60)(90) + (30/60)(120) = 30 + 60 = 90 dollars.
Problem 3Difficulty: Mastery
The table gives f(x). x: 0, 1, 4, 6, 10, 12; f(x): 8, 3, -2, 5, 1, 4. Use a left endpoint Riemann sum only on [1, 10] with partition P = {1, 4, 6, 10}.
Solution & Explanation:The relevant left endpoint values are f(1) = 3, f(4) = -2, and f(6) = 5. The widths are 3, 2, and 4, so 3(3) + 2(-2) + 4(5) = 25.
