The mathematical constant Pi is an irrational number with value approximately 3.1415928... The precise value of this constant ca

tatiyna

Answer:

I am writing a Python program:

def approxPIsquared(error):

previous = 8

new_sum =0

num = 3

while (True):

new_sum = (previous + (8 / (num ** 2)))

if (new_sum - previous <= error):

return new_sum

previous = new_sum

num+=2

print(approxPIsquared(0.0001))

Explanation:

I will explain the above function line by line.

def approxPIsquared(error):

This is the function definition of approxPlsSquared() method that takes error as its parameter and approximates constant Pi to within error.

previous = 8 new_sum =0 num = 3

These are variables. According to this formula:

Pi^2 = 8+8/3^2+8/5^2+8/7^2+8/9^2+...

Value of previous is set to 8 as the first value in the above formula is 8. previous holds the value of the previous sum when the sum is taken term by term. Value of new_sum is initialized to 0 because this variable holds the new value of the sum term by term. num is set to 3 to set the number in the denominator. If you see the 2nd term in above formula 8/3^2, here num = 3. At every iteration this value is incremented by 2 to add 2 to the denominator number just as the above formula has 5, 7 and 9 in denominator.

while (True): This while loop keeps repeating itself and calculates the sum of the series term by term, until the difference between the value of new_sum and the previous is less than error. (error value is specified as input).

new_sum = (previous + (8 / (num ** 2))) This statement represents the above given formula. The result of the sum is stored in new_sum at every iteration. Here ** represents num to the power 2 or you can say square of value of num.

if (new_sum - previous <= error): This if condition checks if the difference between the new and previous sum is less than error. If this condition evaluates to true then the value of new_sum is returned. Otherwise continue computing the, sum term by term.

return new_sum returns the value of new_sum when above IF condition evaluates to true

previous = new_sum This statement sets the computed value of new_sum to the previous.

For example if the value of error is 0.0001 and previous= 8 and new_sum contains the sum of a new term i.e. the sum of 8+8/3^2 = 8.88888... Then IF condition checks if the

new_sum-previous <= error

8.888888 - 8 = 0.8888888

This statement does not evaluate to true because 0.8888888... is not less than or equal to 0.0001

So return new_sum statement will not execute.

previous = new_sum statement executes and now value of precious becomes 8.888888...

Next num+=2 statement executes which adds 2 to the value of num. The value of num was 3 and now it becomes 3+2 = 5.

After this while loop execute again computing the sum of next term using new_sum = (previous + (8 / (num ** 2)))

new_sum = 8.888888.. + (8/(5**2)))

This process goes on until the difference between the new_sum and the previous is less than error.

For a new version of processor, suppose the capacitive load remains, how much more energy will the processor consume if we incre

xxMikexx [17]

Answer:

72.80 % more energy will be consumed.

Explanation:

First of all, let us have a look at the formula of energy for a processor.

$E = CV^2f$

Where, $E$ is the energy

$C$ is the capacitance

$V$ is the voltage and

$f$ is the clock rate.

Let $E_1$ be the energy of older processor.

$C_1$ be the capacitance of older processor.

$V_1$ be the voltage of older processor

$f_1$ be the capacitance of older processor

So, $E_1 = C_1V_1^2f_1$ ....... (1)

and

Let $E_2$ be the energy of newer processor.

$C_2$ be the capacitance of newer processor.

$V_2$ be the voltage of newer processor

$f_2$ be the capacitance of newer processor

$E_2 = C_2V_2^2f_2$ ....... (2)

Dividing equation (2) with equation (1):

$\dfrac{E_2}{E_1} = \dfrac{C_2V_2^2f_2}{C_1V_1^2f_1}$

As per given statement:

$C_1=C_2$

$V_2=1.2\times V_1$

$f_2=1.2\times f_1$

Putting the values above:

$\dfrac{E_2}{E_1} = \dfrac{C_1\times (1.2V_1)^2\times 1.2f_1}{C_1V_1^2f_1}\\\Rightarrow \dfrac{E_2}{E_1} = \dfrac{(1.2)^2\times 1.2}{1}\\\Rightarrow \dfrac{E_2}{E_1} = 1.728\\\Rightarrow \bold{E_2 = 1.728 \times E_1}$

Energy consumed by newer processor is <em>1.728 </em>times the energy consumed by older processor.

OR

<em>72.80 %</em> more energy will be consumed by the newer processor.

How are clustering and Network Load Balancing similar?

Elza [17]

Answer:

Load balancing is the mechanism happening between the different components to achieve the aim independently in the server. They are not aware of the presence of the other resources with them.

Clustering is the process in which the components work to gain the desired results in the form of group.They work in group so that there are no chances of crash in server.

The similarity arises between these two process are :

They have capability to work even after failure of system
Can have unnecessary access to the information
Scalable

Write a program to find all integer solutions to the equation 4x + 3y -9z = 5 for values of x, y, and z between 0 to 100.

rjkz [21]

Answer:

Following are the code to the given question:

#include <iostream>//header file

using namespace std;

int main()//main method

{

int c= 0;//defining integer variable to count number of solutions

int x,y,z;//defining integer variable which is used in the loop

for (x = 0; x <= 100; x++)//defining for loop to x value

for (y = 0; y <= 100; y++)//defining for loop to y value

for (z = 0; z <= 100; z++)//defining for loop to z value

if (4 * x + 3 * y - 9 * z == 5)//use if to check given condition

{

c++;//increment count value

cout << "(" << x << "," << y << "," << z << ")";//print solutions

cout << (c % 11? " " : "\n");//use for add file solution in a row

}

cout << "\n\nThere are " << c << " solution(s)\n";//print solution couts

return 0;

}

Output:

Please find the attached file.

Explanation:

In the above-given code four integer variable "x,y,z, and c" is declared, in which "x,y, and z" is used in the for loop with the if conditional statement that checks the given condition and prints the solution and the "c" variable is used to counts the number of solution, and at the last, it uses the print method to print its values.

What dose it need For a device to be considered a kind of computer

const2013 [10]

Answer:

Micro controller or MCU (Microcontroller Unit)

Explanation:

Micro Controller Unit is basically a computer on a chip with all components fabricated onto it. It is the core component of a computer.

A Micro Controller has:

Central Processing Unit CPU
Random access memory RAM
Read-only memory ROM
I/O peripherals
Timers
Serial COM ports

all fabricated on a single chip so that it may be connected via buses for providing the desired functionality.
