Assume that a two-dimensional rectangular array of integers called matrix has been declared with six rows and eight columns. Wri

tatyana61 [14]

Answer & Step-by-step explanation:

//written in java

// program uses a for loop to exchange the contents of the second column with the fifth column in a six rows and eight columns array

public class Main{

public static void main(String[] args) {

//specifying an integer to hold values during swap

int value = 0;

//sample array of

int[][] arr = {

{1, 2, 3, 4, 5, 6, 7, 8},

};

//loop to swap column 2 and column 5

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

for (int j = 0; j < arr[i].length; j++) {

if(j==1){

value = arr[i][j];

}

if(j==4){

arr[i][1] = arr[i][j];

arr[i][j] = value;

}

//loop to print out result

for (int[] ints : arr) {

for (int anInt : ints) System.out.print(" " + anInt);

System.out.print("\n");

}

Find the value of x and y

Natalija [7]

Hello and Good Morning/Afternoon:

Let's take this problem step-by-step:

What does the information want:

value of x
value of y

Let's gather some information:

ΔA'BC' and ΔABC are similar triangles

⇒ Angle B is shared by both triangles

⇒ Angle A' and A are the same, as they are both on parallel

lines, A'C' and AC, and both angles are formed with the

same line AB

⇒ by the Angle-Angle Theorem*, they are similar triangles

If they are similar triangles:

⇒ their side lengths are proportional to each other

let's find x's value

⇒ let's set up a proportion

$\frac{A'B}{AB} =\frac{A'C'}{AC} \\\frac{30}{x+30} =\frac{14}{22} \\14(x+30) = 30*22\\14x + 420 = 660\\14x = 240\\x = 17.143$

let's find y's value

⇒ let's set up a proportion

$\frac{BC'}{BC} =\frac{A'C'}{AC} \\\frac{y}{y+15} =\frac{14}{22} \\22y=14(y+15)\\22y=14y+210\\8y=210\\y=26.25$

Answer:

x= 17.143
y = 26.25

Hope that helps!
