Consider a system running ten i/o-bound tasks and one cpu-bound task. assume that the i/o-bound tasks issue an i/o operation once for every millisecond of cpu computing and that each i/o operation takes 10 milliseconds to complete. also assume that the context switching overhead is 0.1millisecond and that all processes are long-running tasks. what is the cpu utilization for a round-robin scheduler when: a. the time quantum is 1 millisecond b. the time quantum is 10 milliseconds

The volume v and paper surface area a of a conical paper cup are given by where r is the radius of the base of the cone and h is the height of the cone. a. by eliminating h, obtain the expression for a as a function of r and v. b. create a user-de ned function that accepts r as the only argument and computes a for a given value of v. declare v to be global within the function. c. for v ! 10 in.3 , use the function with the fminbnd function to compute the value of r that minimizes the area a. what is the corresponding value of the height h? investigate the sensitivity of the solution by plotting v versus r. how much can r vary about its optimal value before the area increases 10 percent above its minimum value?
