Part a) A 0.50% C hypoeutectoid plain-carbon steel is slowly cooled from 940C to temperature just slightly above 727C. Calculate the weight percent austenite present in the steel Calculate the weight percent proeutectoid ferrite present in the steel Part b) A 0.50% C hypoeutectoid plain-carbon steel is slowly cooled from 940C to temperature just slightly below 727C. Calculate the weight percent eutectoid ferrite (note that you need to calculate total ferrite and subtract the proeutectoid ferrite) and the weight percent eutectoid cementite present in the steel.

explanation:

which ordered pair is not in the solution

y > -1/2x + 5

y ≤ 3x - 2

a) (5,3) b) (4,3)

c) (3,4) d) (4,4)

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
