One of the industrial robots designed by a leading producer of servomechanisms has four major components. components’ reliabilities are .98, .95, .94, and .90. all of the components must function in order for the robot to operate effectively. designers want to improve the reliability by adding a backup component. due to space limitations, only one backup can be added. the backup for any component will have the same reliability as the unit for which it is the backup. what will be the highest reliability the robot can achieve?

import math

x=int(input("enter a number: "))

print (math.sqrt(math.fabs(

answer:

the average distance would be 20ly

Explanation:

100,000ly times 5,000ly=20ly

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
