Use the method of cylindrical shells to find the volume generated by rotating the region bounded by the curves y = 3 + 2x - x^(2) and y + x = 3 about the y-axis. Below is a graph of the bounded region. Use the method of cylindrical shells to find the volume generated by rotating the region bounded by the given curves about the specified axis. Sketch the curves including all relevant points, and shade the area being rotated. If graphing is not sufficient, no credit. Graphing is more important than the answer. Exact answer. y=\sqrt(x),x=2y, about x=6 x=2y^(2),x=y^(2)+1, about y=-2

Use the horizontal model, or write the journal entries, to show the effect of selling each of the three assets for their respective estimated market values. Partial-year depreciation adjustments for 2023 can be ignored. Explain to Mr. Gerald what he meant when he said we need to get a handle on the value of some of the older equipment. What the books say, and what it's really worth, are two different things.

A study sponsored by the NIH was conducted to help determine whether a 10-day cycle of antibiotics is better than a 5-day cycle of antibiotics at curing ear infections among children under age 2. 48 children who came into the clinic with ear infections were randomized to a 10-day cycle of antibiotics (group 1), and 88 children were randomized to the standard 5-day cycle (group 2). After 2 weeks it was determined that 4 children on the 10-day cycle (group 1) still had ear infections and 20 children on the standard 5-day cycle (group 2) still had ear infections. What is the standard error of using plus 4 method?

Question 2: An internal combustion engine has a cast iron flywheel that could be considered as a uniform thin disc. This flywheel was found to yield when it rotates with a speed of 9129 RPM. Determine the maximum stress that would be induced in this disc if a maximum permissible speed of 6054 RPM was allowed (elastic deformation). Assume the following properties for the cast iron: $\rho$ = 7180 kg/m$^3$, $\sigma_Y$ = 200 MPa and $\nu$ = 0.25.

Question 2. In class we saw the following formula (for n ? 1): ?_{i=1}^{n} i = n(n+1)/2. Many students asked about how the upper and lower bounds affect this formula. You will explore that in this problem. In this problem you may use the formula above (with bounds 1 and n), and you may use (1) Find a formula for ?_{i=0}^{n} i, and explain how you know your formula is correct. (2) Compute ?_{i=3}^{7} i by expanding it out. (3) Find a formula for ?_{i=3}^{n} i, and explain how you know your formula is correct. (Here n ? 3. Make sure your general formula gives you the same answer as your computation in part 2.) (4) Find a formula for ?_{i=m}^{n} i, and explain how you know your formula is correct. (Here 0 ? m ? n. Make sure your general formula gives you the same answer as your computation in parts 2, and your formula in part 3.) (5) Write a short reflection (about 1 paragraph) about the relationship between coming up with general formulas (parts 3 and 4), and example computations (part 2). In what ways can this approach be helpful to you?
