Please help Ill give you brainliest if I get 2 answers. Which is used to input information on a laptop?

Polygon transform (25 points). Write a library of static methods that performs various geometric transforms on polygons. Mathema

kari74 [83]

Answer:

import java.lang.*; //for using Math.cos() and Math.sin() and Math.toRadians() funcitons in rotate method

public class PolygonTransform

{

public static double[] copy(double[] array)

{

double[] newArray = new double[array.length];

for(int i=0;i<array.length;i++)

{

newArray[i] = array[i];

return newArray;

}

public static void scale(double[]x,double[]y,double alpha)

{

for(int i=0;i<x.length;i++)

{

x[i] *= alpha;

y[i] *= alpha;

}

public static void translate(double[]x,double[]y,double dx,double dy)

{

for(int i=0;i<x.length;i++)

{

x[i] += dx;

y[i] += dy;

}

public static void rotate(double[] x, double[]y,double theta)

{

double rad = Math.toRadians(theta);

double temp;

for(int i=0;i<x.length;i++)

{

temp = x[i]; //For storing temporarily the previous value of x before changing so tha it can be used in changing y

x[i] = x[i]*Math.cos(rad) - y[i]*Math.sin(rad);

y[i] = y[i]*Math.cos(rad) + temp*Math.sin(rad);

}

public static void main(String args[])

{

//This is just implementing you testcase discripted.

double[]x = new double[4];

double[]y = new double[4];

StdDraw.setScale(-5.0, +5.0);

x = { 0, 1, 1, 0 };

y = { 0, 0, 2, 1 };

double alpha = 2.0;

StdDraw.setPenColor(StdDraw.RED);

StdDraw.polygon(x, y);

scale(x, y, alpha);

StdDraw.setPenColor(StdDraw.BLUE);

StdDraw.polygon(x, y);

// Translates polygon by (2, 1).

StdDraw.setScale(-5.0, +5.0);

x = { 0, 1, 1, 0 };

y = { 0, 0, 2, 1 };

double dx = 2.0, dy = 1.0;

StdDraw.setPenColor(StdDraw.RED);

StdDraw.polygon(x, y);

translate(x, y, dx, dy);

StdDraw.setPenColor(StdDraw.BLUE);

StdDraw.polygon(x, y);

// Rotates polygon 45 degrees.

StdDraw.setScale(-5.0, +5.0);

x = { 0, 1, 1, 0 };

y = { 0, 0, 2, 1 };

double theta = 45.0;

StdDraw.setPenColor(StdDraw.RED);

StdDraw.polygon(x, y);

rotate(x, y, theta);

StdDraw.setPenColor(StdDraw.BLUE);

StdDraw.polygon(x, y);

}

Using Structured Query Language (SQL), create a query that gets the following data from the sakila database:

bezimeni [28]

Queries to get data from sakila database using Structured Query Languange (SQL):

Assuming that you have created a Database already, with tables in it, containing at least 50 records and these fields:

ACTOR_LASTNAME, ACTOR_FIRSTNAME, FILM_TITLE

Take note that the database and table name is both "sakila".

1. We can fetch, display or get data using SELECT command or query. Let's type the command like this:

SELECT ACTOR_LASTNAME, ACTOR_FIRSTNAME, FILM_TITLE FROM sakila 

The command above is called SELECT command that would allow you to display records inside your table. Normally SQL programmers would execute SELECT * command, but since we are just required to display three (3) columns only, then we could just select the column names for our data display. Your columns are: SELECT ACTOR_LASTNAME, ACTOR_FIRSTNAME and FILM_TITLE.

2. For the second command or query, we can execute this:

SELECT ACTOR_LASTNAME FROM sakila WHERE ACTOR_LASTNAME 'M%' ORDER BY ACTOR_LASTNAME . 

The select where command is like a conditional statement (IF). Where is the statement used to display ACTOR_LASTNAME field starting with letter M. The ORDER BY command is the arrangement of the names in alphabetical order.

A group of children want to play a game, called UnMonopoly, where the player with the most money must give half of his/her money

pogonyaev

Answer:

Using max heap

Explanation:

Information of each player - Structure. Here one field should be the total value of the properties for taking comparison between the players. Information of each players - An array of the structures (property). Information of each property - structure. Information about all property - array of the structures. Chance and also community chest cards - the queue in data structures.

We can use max heap and then the root will be children having the highest amount of money.
