Suppose that a 1600-byte datagram (identification #20) must transit a network which has a 740-byte MTU. Assume the minimum IP and TCP header sizes, i. e., the IP header is 20 bytes and the TCP header is 20 bytes.
1. How many fragments are created?
2. How many bytes of application data are carried in the first fragment?
3. How many bytes of application data are carried in the second fragment?
4. How many bytes of application data are carried in the last fragment?
5. What is the identification number of the second fragment?
6. What is the fragment offset in the last fragment?

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?
