Suppose window size be 16. Only the 8th packet is lost during transmission. Assume the following: • Packet transmission delay be A, timeout interval be B, and round-trip delay be C. • The path is symmetric in terms of delay. • Timeout is greater than the time to send 16 packets plus the round trip time. • The ACK transmission delay is negligible. How much time will it take to send all 16 packets to the receiver by each protocol? Express the equation using notations mentioned here such as A, B, and C.

This program will store roster and rating information for a soccer team. coaches rate players during tryouts to ensure a balanced team. (1) prompt the user to input five pairs of numbers: a player's jersey number (0 - 99) and the player's rating (1 - 9). store the jersey numbers in one int vector and the ratings in another int vector. output these vectors (i.e., output the roster). (3 pts) ex: enter player 1's jersey number: 84 enter player 1's rating: 7 enter player 2's jersey number: 23 enter player 2's rating: 4 enter player 3's jersey number: 4 enter player 3's rating: 5 enter player 4's jersey number: 30 enter player 4's rating: 2

Robots with telescoping arms are sometimes used to perform tasks (e.g., welding or placing screws) where access may be difficult for other robotic types. during a test run, a robot arm is programmed to extend according to the relationship r = 3 + 0.5cos(4θ) and the arm rotates according to the relationship θ=−π4t2+πt , where r is in feet, θ is in radians, and t is in seconds. use a computer program to plot the path of tip a in x and y coordinates for 0 ≤ t ≤ 4s.
