Diano4ka-milaya [45]

Answer:

Registry

Explanation:

Windows Registry is used to store the configuration and setting information for hardware and software program which is critical for Windows operation. The registries are structured in hierarchical database model.  

Basically, hierarchical database model is akin to a tree format which consist of the parent nodes and their child nodes.  For example, a node named as HKEY_LOCAL_MACHINE can possess child nodes HARDWARE, SOFTWARE AND SYSTEM.

The node in the tree is also termed as a key.

Write the definition of a function named quadratic that receives three double parameters a, b, c. If the value of a is 0 then th
VMariaS [17]

Answer:

#include <iostream>

#include <cmath>

using namespace std;

//initialize function quadratic

void quadratic(double, double, double);

int main() {

   //declare double variables a, b and c

   double a,b,c;

   //take input from user

   cin>>a>>b>>c;

   //call function quadratic

   quadratic(a,b,c);

return 0;

}

void quadratic(double a, double b, double  c){

   double root,n;

   //check if variable a is equal to zero

   if(a==0){

       cout<<"no solution for a=0"<<endl;

       return;

   }

   //check if b squared - 4ac is less than zero

   else

   if(((b*b)-(4*a*c))<0){

       cout<<"no real solutions"<<endl;

       return;

   }

   //print the largest root if the above conditions are not satisfied

   else{

       n=((b*b)-(4*a*c));

       root=(-b + sqrt(n)) / (2*a);

       cout<<"Largest root is:"<<root<<endl;

   }

   return ;

}

Explanation:

Read three double variables a, b and c from the user and pass it to the function quadratic. Check if the value of variable a is equal to zero. If true, print "no solution for a=0". If this condition is false, check if b squared - 4ac is less than zero. If true, print "no real solutions". If this condition is also false, calculate the largest solution using the following formula:

largest root = (-b + square root of (b squared - 4ac)) / (2*a)

Input 1:

2 5 3

Output 2:

Largest root is:-1

Input 2:

5 6 1

Output 2:

Largest root is:-0.2

Answer:

<em>The Triangle.java file is not provided; However, the program is as follows;</em>

<em>Comments are used for explanatory purpose</em>

<em>Also see attachment for Triangle.java program file</em>

<em />

import java.util.*;

public class triangle

{

public static void main(String [] args)

{

 Scanner input = new Scanner(System.in);

 //Declare variables

 double base1, height1, base2, height2;

 //Prompt user for inputs

 System.out.println("Provide values for the base and height of the two triangles");

 System.out.print("Base of Triangle 1: ");

 base1 = input.nextDouble();

 System.out.print("Height of Triangle 1: ");

 height1 = input.nextDouble();

 System.out.print("Base of Triangle 2: ");

 base2 = input.nextDouble();

 System.out.print("Height of Triangle 2: ");

 height2 = input.nextDouble();

 //Compare and Print Results

 if(0.5 *base1 * height1 > 0.5 * base2 * height2)

 {

  System.out.print("Triangle with larger area: Base: "+base1+" Height: "+height1+" Area: "+(0.5 * base1 * height1));

 }

 else

 {

  System.out.print("Triangle with larger area: Base: "+base2+" Height: "+height2+" Area: "+(0.5 * base2 * height2));

 }

}

When researching which keywords should be included in a résumé, what four sources are valuable resources?
zimovet [89]
I would suggest the following sources

1) job postings - those offer include the phrases that the employers themselves want to hear

2) keyword lists - they're made for looking for keywords!

3) professional site's skills sections. You could use LinkedIn or any other professional site.

4)Sometimes you can find software that can suggest keywords for you
