Consider a processor that runs at 5 ghz and 1 volt. when running a given cpu-bound program, the processor consumes 100 w, of which 20 w is leakage. the program takes 5 seconds to execute. the processor is capable of running at different voltages and frequencies. assume that the processor is capable of executing safely at voltages between 0.8 v to 1.2 v. voltage and frequency follow a linear relationship (i. e., if voltage doubles, frequency doubles as well. compute the following values:

(a) the shortest time it would take to execute the program.

(b) the lowest power to execute the program.

(c) the lowest energy to execute the program.

The β€œrule of 72” is used to approximate the time required for prices to double due to inflation. if the inflation rate is r%, then the rule of 72 estimates that prices will double in 72/r years. for instance, at an inflation rate of 6%, prices double in about 72/6 or 12 years. write a program to test the accuracy of this rule. for each interest rate from 1% to 20%, the program should display the rounded value of 72/r and the actual number of years required for prices to double at an r% inflation rate. (assume prices increase at the end of each year.)
