Express the definite integral as a limit of Riemann sums. DO NOT EVALUATE. k (x² + 2 ) dx
Please show full workings for both parts of the answer because I keep getting the answer wrong. Thumbs up will be given to the workings with correct answers! 7. Set up (do not solve) a definite integral that would give the area of the region under the graph of y = In x, above the x-axis, between the vertical lines x = 1 and x = e. Sketch the graph. You don't need to express with the Riemann sum definition...

2. Write the limit of a Riemann sum which equals the work described, then compute it. A 50m long cable which weighs 200N hangs from a building which is 80m tall. Find the work done in lifting the entire cable. Indicate units of measure in the final answer. (15 points)
1. (13 points) Use the limit of a Riemann Sum (i.e. sigma notation and the appropriate summation formulas) to evaluate the net-signed area between the graph of f(0) = 23 – 3 and the interval (0, 2). Let 27 be the right endpoint of the k-th subinterval (where all subintervals have equal width). Give your answer as a single integer or frac- tion, whichever is appropriate. Using any technique other than a limit of a Riemann Sum will earn no...
6. Express as the limit of a Riemann sum. (2x 5x-2) dx 7. A rectangul vertical sides which run n ar region with area 4800 square feet is to be enclosed within a fence. The two orth-south will use fencing materials costing $2.00 per foot, while the zontal sides require fencing materials costing $5.00 per foot. Find the dimensions of the region which gives the minimum cost. 6. Express as the limit of a Riemann sum. (2x 5x-2) dx 7....
