Write a Matlab script to create a movie with these stipulations: • The base shape is the polygon whose vertices are the points (0, 0), (1, −1), (0, 2) and (−1, −1).

• The size of the shape gets bigger and smaller as t increases. The "size" of the shape becomes 0 every cycle, but is never negative.

• Note that at the start there is a right angle at the origin. As t increases, this point traces out a counter-clockwise closed curve.

• The shape as a whole spins in a clockwise orientation.

Suppose we have a byte addressable computer that has a 32-byte cache with 8 bytes per block. the memory address is 8 bits long. the system accesses memory addresses (in hex) in this exact order: 6e, b9, 17, e0, 4e, 4f, 50, 91, a8, ab, ad, 93, and 94. (a) assuming the cache is direct mapped, what memory addresses will be in cache block 2 after the last address has been accessed? (b) assuming the cache is direct mapped, what is the hit ratio for the entire memory reference sequence given, assuming the cache is initially empty? (c) assuming the cache is 2-way set associative with a lru replacement policy, what is the hit ratio?

For all machines-not just hammers- the user applies force force to the machine to the machine over a certain distance. a. input b. output c. duo d. none of the above

Write a program that reads a file consisting of students’ test scores in the range 0–200. it should then determine the number of students having scores in each of the following ranges: 0–24, 25–49, 50–74, 75–99, 100–124, 125–149, 150–174, and 175–200. output the score ranges and the number of students. (run your program with the following input data: 76, 89, 150, 135, 200, 76, 12, 100, 150, 28, 178, 189, 167, 200, 175, 150, 87, 99, 129, 149, 176, 200, 87, 35, 157, 189.)
