Unformatted text preview: nanni (arn437) Assignment 3 guntel (54940) 1 This printout should have 5 questions. Multiplechoice questions may continue on the next column or page find all choices before answering. 001 10.0 points The graph of a function f is shown in 2 4 6 8 10 2 4 6 8 Compute the Riemann sum 10 summationdisplay i = 1 f ( x * i ) x when [0 , 10] is subdivided into ten equal subintervals [ x i 1 , x i ] and x * 1 = x 1 , x * 2 = x 2 , . . . , x * 10 = x 10 . 1. Riemann sum = 52 2. Riemann sum = 55 correct 3. Riemann sum = 54 4. Riemann sum = 51 5. Riemann sum = 53 Explanation: Since x = 1 we see that Riemann sum = 55 , reading off the values of f ( x * 1 ) , f ( x * 2 ) , . . . , f ( x * 10 ) from the graph of f . 002 10.0 points Use properties of integrals to determine the value of I = integraldisplay 5 f ( x ) dx when integraldisplay 7 f ( x ) dx = 5 , integraldisplay 7 5 f ( x ) dx = 9 ....
