The long-run total cost faced by firms that hire operations managers with average talent is given by lt c a = 200 + 2 q 2 . the associated marginal cost function is given by lmc a = 4q, and the corresponding long-run average total cost is lat c a = 200/q + 2q. a. derive the firm supply curve for ice cream producers with extraordinary operations managers. b. derive the firm supply curve for ice cream producers with average operations managers. c. the minimum lat c a (for firms with average operations managers) is $40, achieved when those firms produce 10 units of output. the minimum lat c e (for firms with exceptional operations managers) is $28.28, achieved when those firms produce 14 units of output. explain why, given only that information, it is not possible to determine the long-run equilibrium price of 5-gallon tubs of ice cream.

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.
