Multiply and write answer in lowest terms. ×

Perform the indicated operation: [x] + [y]

For the following problem, indicate where the mistake is (if any) and explain how it can be corrected. Be sure to include the correct answer. If there is no mistake, explain the general process for working the problem.  

Using Grover’s quantum algorithm, how many quantum calculations would it take to break 256-bit security (instead of trying 2256 keys with brute force or 2256/2 with classical computing)? A: 21 B: 264 C: 2128 D: 2255  

Besides number of operations, other factors affect the cost of an attack. Which of the following is NOT one of them?

Shor’s Algorithm is thought to break, what? 

Provide an appropriate response.Explain what is represented by the area and perimeter of a shape.

Use formulas for perimeter and area to solve the problem.A window consists of a rectangle and a semicircle (half a circle). The dimensions of the rectangle are 9 ft by 4 ft. Find the area of the window. If necessary, use 3.14 for π and round the result to the nearest tenth.4 ft

What certificate is the first certificate created by a CA?

Provide an appropriate response. If force = pressure × area, how many pounds of force are produced by a pressure of [x] psi (pounds per square inch) on a piston whose surface area is [y] in2?
