Superinc. uses a risk-adjustment when evaluating projects of different risk. its overall (composite) wacc is 7%, which reflects the cost of capital for its average asset. its assets vary widely in risk, and superinc. evaluates low-risk projects with a risk-adjusted project cost of capital of 6.5%, average-risk projects at 7%, and high-risk projects at 7.5%. should the following project be adopted if risk is low, average, or high? col1 time 0 1 2 3 4 5 col2 cf -$1,000 $125 $200 $250 $325a. adopt only if risk is low b. adopt if risk is low or average c. adopt at any of these risk levels d. do not adopt under any of these risk levels

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.
