A. On a highway

Explanation:

On a highway is NOT a place where you are likely to encounter a pedestrian.

Pedestrians found on highways usually get arrested or get a ticket.

If Count = 1 and X = 3, what will be displayed when code corresponding to the following pseudocode is run? Do Set Y = Count + X

kirill115 [55]

Answer:

4 5 6

Explanation:

Since there is a do-while loop, you need to check the values for each iteration until the condition (Count <= X) is not satisfied.

First iteration -> Count = 1 and X = 3, Y = 1 + 3, Write Y -> 4

Second iteration -> Count = 2 and X = 3, Y = 2 + 3, Write Y -> 5

Third iteration -> Count = 3 and X = 3, Y = 3 + 3, Write Y -> 6

After the third iteration count is equal to 4 and X is equal to 3. That is why loop ends.

Answer:

#include <iostream>

#include <cstdlib>

using namespace std;

int main() {

char Keep_Going = '-';

int nextBid = 0;

srand(5);

while (Keep_Going != 'n') { //<-- solution

nextBid = nextBid + (rand()%10 + 1);

cout << "I'll bid $" << nextBid << "!" << endl;

cout << "Continue bidding? ";

cin >> Keep_Going;

}

cout << endl;

return 0;

The Pentium 4 Prescott processor, released in 2004, has a clock rate of 3.6 GHz and voltage of 1.25 V. Assume that, on average,

Zarrin [17]

Answer:

a) C = 3.2 x 10^-8 F, C = 2.9 x 10^-8 F

b) 10%, 42.86%, 0.11, 0.75

c) 0.849 volts to maintain the same leakage current in the Pentium 4 Prescott Processor. 0.783 Volts to maintain the same leakage current in the Core i5 Ivy Bridge Processor.

Explanation:

For the Pentium 4 Prescott processor:

Clock rate (f) = 3.6 GHz

Voltage (V) = 1.25 V

Static Power Consumption = 10 W

Dynamic Power Consumption = 90 W

For the Core i5 Ivy Bridge processor:

Clock rate (f) = 3.4 GHz

Voltage (V) = 0.9 V

Static Power Consumption (SP) = 30 W

Dynamic Power Consumption (DP) = 40 W

(a) To find the average capacitive loads, use the formula:

DP = (1/2) x C x V² x f

Rearranging:

C = (2 x DP)/(V² x f)

For the Pentium 4 Prescott processor:

C = (2 x 90) / [(1.25)² x 3.6 x 10^9]

C = 3.2 x 10^-8 F

For the Core i5 Ivy Bridge processor:

C = (2 x 40) / [(0.9)² x 3.4 x 10^9]

C = 2.9 x 10^-8 F

(b) Percentage of the total dissipated power comprised by the static power can be found by the formula:

[Static Power/(Static Power + Dynamic Power)] x 100

For the Pentium 4 Prescott Processor:

[10/(90+10)] x 100 = 10%

For the Core i5 Ivy Bridge Processor:

[30/30+40] x 100 = 42.86 %

Ratio of static power to dynamic power for each technology can be computed as:

Pentium 4 Prescott: 10/90 = 0.11

Core i5 Ivy Bridge: 30/40 = 0.75

P = DP + SP

For Static Power we have the formula:

SP = VI where I is the leakage current.

I = SP/V

For Pentium 4 Prescott: I = 10/1.25 = 8A

For Core i5 Ivy Bridge: I = 30/0.9 = 3.33 A

The total disspited power is reduced by 10%, meaning the ratio of new power to old power must be 90% = 0.9. So,

New Power/Old Power = 0.9

For Pentium 4 Prescott:

DP + SP / 100 = 0.9

VI + CV²F = 0.9 x 100

V(8) + (3.2 x 10^-8)V²(3.6 x 10^9) = 90

8V + 115.2V² - 90 = 0

By solving the quadratic equation, we get the positive answer as 0.849. This means that the voltage should be reduced to 0.849 volts to maintain the same leakage current in the Pentium 4 Prescott Processor.

For Core i5 Ivy Bridge:

DP + SP / 70 = 0.9

V(3.33) + (2.9 x 10^-8)V²(3.4 x 10^9) = 70 x 0.9

3.33V +98.6V² -63 = 0

By solving the quadratic equation we get the positive answer as 0.783. This means that the voltage should be reduced to 0.783 Volts to maintain the same leakage current in the Core i5 Ivy Bridge Processor.
