Your company has sales of $ 93,600 this year and cost of goods sold of $ 64,700. You forecast sales to increase to $ 117, 400 next year. Using the percent of salesâ method, forecast nextâ year's cost of goods sold.

Problem 3: access control pokeygram, a cutting-edge new email start-up, is setting up building access for its employees. there are two types of employees: managers and engineers, and there are three departments: security, networking, and human resoures. each employee works in a single department, and each department is housed on a different floor. managers are allowed access to any floor, while engineers are allowed access only to their own floor. there are three badge-operated elevators, each going up to only one distinct floor. every employee has one badge. pokeygram wants to use the best possible access control method in order to minimize delay for the elevators (a) access control matrix, 1. which of the following would you recommend that pokeygram use: (b) access control lists, or (c) capabilities? make sure to justify your answer. 2. what, if any, would be the benefits (and/or disadvantages) of using rbac (role-based access control) in this situation? keep your solution for this problem limited to 10-12 lines of text.

Refrigerant 22 in a refrigeration system enters one side of a counterflow heat exchanger at 12 bar, 28 c. the refrigerant exits at 12 bar, 20 c. a separate stream of r-22 enters the other side of the heat exchanger as saturated vapor at 2 bar and exits as superheated vapor at 2 bar. the mass flow rates of the two streams are equal. stray heat transfer from the heat exchanger to its surroundings and kinetic and potential energy effects are negligible. determine the entropy production in the heat exchanger, in kj/k per kg of refrigerant flowing. what gives rise to the entropy production in this application?
