(a) Assuming the power plant that supplies 110 V electricity to the dorm is 10 km away and the two aluminum transmission cables use 0-gauge wire with a diameter of 8.252 mm, estimate the percentage of the total power supplied by the power company that is lost in the transmission. (b) What would be the result is the power company delivered the electric power at 110 kV?

Question: LO9.4You are considering two possible companies for investment purposes. The following data is available for each company. Additional Information: Company A: Bad debt estimation percentage using the income statement method is 6%, and the balance sheet method is 10%. The $230,000 in Other Expenses includes all company expenses except Bad Debt Expense. Company B: Bad debt estimation percentage using the income statement method is 6.5%, and the balance sheet method is 8%. The $140,000 in Other Expenses includes all company expenses except Bad Debt Expense. Compute the number of days’ sales in receivables ratio for each company for 2019 and interpret the results (round answers to nearest whole number).If Company A changed from the income statement method to the balance sheet method for recognizing bad debt estimation, how would that change net income in 2019? Explain (show calculations).If Company B changed from the balance sheet method to the income statement method for recognizing bad debt estimation, how would that change net income in 2019? Explain (show calculations).What benefits do each company gain by changing their method of bad debt estimation?Which company would you invest in and why? Provide supporting details.

Question: As the project leader for the software engineering of the new features of next year’s car model, you have been tasked to deliver the lane departure system, additional navigational features on the dashboard computer screen, and a heads-up display system that shows the speed and any warnings displayed onto the windshield. When the product was demoed, the user of the system indicates that they also want to include navigational aids from the navigational system onto the windshield heads-up display. When the navigation system is providing directions, the heads-display on the windshield should show an arrow when getting close to a turn. This functionality was not a part of the original requirements, but rather is a change to the scope of the project. What do you do? What impact will this have on the process and SDLC models being used for the project? Further imagine the new functionality is critical for safety and could potentially prevent accidents. Would your approach change?
