A password hash function is applied 12 times to secure a password. If it takes 21 minutes to brute force one application of the hash with the available resources, how long will it take to brute force the password if the available resources are quadrupled.? a. 21 minutes
b. 63 minutes
c. 210 minutes
d. none of the above.

b. 63 minutes

Step-by-step explanation:

Given;

number of times the hash function is applied  = 12

time taken to brute force one application, = 21 minutes

Apply proportion, bearing in mind that 4 available resources should take less time;

1 available resource ------- 21 minutes

4 available resources ------ x

Thus, x  = 21 minutes / 4

When applied  12 times, the time should be

Therefore, the correct option is B, 63 minutes

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
