Question 1 find x where x26+6x13-4 mod 13 2

Part 3: Factorial function In computer science, and other fields, we frequently need to know how many possible combinations are possible given a specific number of numbers or characters. For example, consider three color cards: red (R), green (G), and blue (B). How many different orders are possible of these three cards? RGB, RBG, GRB, GBR, BRG, BGR = six (6) possible combinations The mathematical term for this calculation is factorial (see Factorial Function !Links to an external site. web page) and is expressed using the exclamation point (!). Surprisingly, the JavaScript Math object does not have a function for factorial, so we will write our own. So how do we calculate factorial? The steps to accomplish a task are known as an algorithm. An algorithm is a series of steps that given the same input will always produce the same output. Often, many possible algorithms exist to accomplish the same task. To calculate the factorial of a specific number, we need to multiply every number…

a. Demonstrate that the disc motions employed in the Towers of Hanoi puzzle's traditional recursive technique may be utilised to generate the binary reflected Gray code.b. Demonstrate how to solve the Towers of Hanoi problem using the binary reflected Gray code.

a) A computer has a clock rate of 2GHz. It takes a program 10s to complete on this computer. The number of clock cycles of the program is b) A program has 1x106 instructions. The computer's clock cycle time is 250x10-12 seconds and the CPI is 2.0. Therefore, the CPU time of the program is seconds. c) We use a certain compression program as a benchmark of a certain computer system. The program has 2x10° instructions. The system has a CPI of 0.85, and a clock cycle time of 0.4x109 seconds. When we run the program, it takes 100 seconds to complete on the computer system, whereas it takes 900 seconds to complete on a reference computer. From what you know about the SPEC benchmarks, the SPECratio is
