Write a program that, for four points A, B, C and P, which a) Draws a triangle formed by ABC and a small cross showing the posit

Degger [83]

Answer:

import java.awt.*;

import java.applet.*;

public class DrawTrainlge extends Applet{

static double findDistance(float x1, float y1,float a, float b,float c){

double dis = Math.abs(((a * x1 + b * y1 + c)) / (Math.sqrt(a * a + b * b)));

return dis;

}

public void paint(Graphics g){

Point[] point = new Point[4];

g.drawLine(point[0].x , point[0].y , point[1].x , point[1].y);

g.drawLine(point[0].x , point[0].y , point[2].x , point[2].y);

g.drawLine(point[2].x , point[2].y , point[1].x , point[1].y);

double newdistance = 9999999;

for(int i=0;i<3;i++){

int first = (i+1)%3;

int second = i;

float a = point[first].y - point[second].y;

float b = point[second].x - point[first].x;

float c = a*(point[second].x) + b*(point[second].y);

double dis = findDistance(point[3].x,point[3].y,a,b,c);

if(newdistance > dis){

dis = newdistance;

}

}

g.drawString("Shortest Distance");

g.drawString(dis);

}

}

Explanation:

Inside the findDistance method, find the distance by using the following formula:

Math.abs(((a * x1 + b * y1 + c)) / (Math.sqrt(a * a + b * b)))

Inside the paint method, give your input in the form of four points(A,B,C,D) .

When using powershell, an administrator can use the ____________ cmdlet to create a new dc in a new forest.??

NeX [460]

I am definitely sure that the answer should be: When using powershell, an administrator can use the Install-ADDSForest cmdlet to create a new dc in a new forest. Install-ADDSForest is used to install first domain controller in new forest. To do that, you should execute this command through the command promt. It looks like this: <span>C:\> Install-AddsForest. Then you'll need to set up the attributes.</span>

Write a method swaparrayends() that swaps the first and last elements of its array parameter. ex: sortarray = {10, 20, 30, 40} b

Alexus [3.1K]

In the C programming language, you can't determine the array size from the parameter, so you have to pass it in as an extra parameter. The solution could be:

#include <stdio.h>

void swaparrayends(int arr[], int nrElements)
{
int temp = arr[0];
arr[0] = arr[nrElements - 1];
arr[nrElements - 1] = temp;
}

void main()
{
int i;
int myArray[] = { 1,2,3,4,5 };
int nrElements = sizeof(myArray) / sizeof(myArray[0]);
swaparrayends(myArray, nrElements);

for (i = 0; i < nrElements; i++)
{
printf("%d ", myArray[i]);
}

getchar();
}

In higher languages like C# it becomes much simpler:

  static void Main(string[] args)
  {
int[] myArray = {1, 2, 3, 4, 5};
swaparrayends(myArray);
foreach (var el in myArray)
{
Console.Write(el + " ");
}

Console.ReadLine();
}

static void swaparrayends(int[] arr)
{
  int temp = arr[0];
arr[0] = arr.Last();
arr[arr.Length - 1] = temp;
}

sleet_krkn [62]

An electronic document is any electronic media content that are intended to be used in either an electronic form or as printed output.

Explanation:

Electronic file organization is a key skill for today's work place for many reasons.

It will increase productivity and will help give a clear understanding of what documents should be filed in the shared drive system.
Having a sound file structure will help to improve the over all production of the organization
An electronic file management software system helps organize documents in various ways. So your employees can find files fast and save time. They can accomplish more work in the given amount of time.
Doctor offices and hospitals have digitized all paper medical records, which means they are now using electronic medical records (EMR) systems. If someone does not have organization it could potentially lead to files and or documents going in to the wrong hands.
Learning to use One Drive can also assist me in my present role as a student. It will help me to be organized with my assignments . I will be able to access any other important documents and data.
