For each of the following claims, answer Always True if the statement is true for all possible machines M1 and M2, Always False if the statement is false for all possible machines; and answer Neither otherwise: a. If w ∈ L(M1) then w ∈ L(M).
b. If w ∈ L(M2) then w E L(M).
c. If w ∉ L(M) then w L(M).
d. If w ∉( M2) then w L(M).

Pthreads programming: create and terminate a thread write a c++ program that creates a thread. the main will display a message “hello world from the main”. the main will create a thread that will display a message “hello world from the thread” and then terminates with a call to pthread_exit()

Which type of file can be used to import data into a spreadsheet?

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?
