Write a void function SelectionSortDescendTrace() that takes an integer array and sorts the array into descending order. The function should use nested loops and output the array after each iteration of the outer loop, thus outputting the array N-1 times (where N is the size). Complete main() to read in a list of up to 10 positive integers (ending in -1) and then call the SelectionSortDescendTrace() function. If the input is:
Answer:
Explanation:
The following program is written in Java. The main method asks the user to enter 10 different integer values. These values are saved to an integer array and passed to the SelectionSortDescendTrace() method. This method sorts the array in descending order while printing the entire array after every outer loop cycle. The program was tested and the output can be seen in the attached image below.

int[] myArr = new int[10];
for (int i = 0; i < 10; i++) {
System.out.print("Enter an integer: ");
myArr[i] = in.nextInt();
System.out.print('\n');
}
SelectionSortDescendTrace(myArr);
}
public static void SelectionSortDescendTrace(int[] myArr) {
int temp;
for (int i = 0; i < myArr.length; i++)
{
for (int j = 0; j <myArr.length; j++)
{
if (j != myArr.length - 1)
{
if (myArr[j] < myArr[j + 1])
{
temp = myArr[j];
myArr[j] = myArr[j + 1];
myArr[j + 1] = temp;

Explanation:
, , and angle x and angle y are both in the first quadrant.
Answer:
[tex]\tan(x+y) = 3.73[/tex]
Explanation:
The missing part of the question are:
[tex]\sin(x) = \frac{1}{2}[/tex]
[tex]\cos(y) = \frac{\sqrt 2}{2}[/tex]
Required
[tex]\tan(x + y)[/tex]
First, we calculate [tex]\sin(y)[/tex] and [tex]\cos(x)[/tex]
We have:
[tex]\sin^2(x) + \cos^2(x) = 1[/tex]
So:
[tex](1/2)^2 + \cos^2(x) = 1[/tex]
Collect like terms
[tex]\cos^2(x) = 1 - (1/2)^2[/tex]
[tex]\cos^2(x) = 1 - \frac{1}{4}[/tex]
Take LCM
[tex]\cos^2(x) = \frac{4-1}{4}[/tex]
[tex]\cos^2(x) = \frac{3}{4}[/tex]
Square roots of both sides
[tex]\cos(x) = \frac{\sqrt 3}{2}[/tex]
Similarly,
[tex]\sin^2(y) + \cos^2(y) = 1[/tex]
So:
[tex]\sin^2(y)+(\sqrt 2/2)^2 = 1[/tex]
[tex]\sin^2(y)+ (2/4) = 1[/tex]
[tex]\sin^2(y)+1/2 = 1[/tex]
Collect like terms
[tex]\sin^2(y) = 1 - 1/2[/tex]
Take LCM
[tex]\sin^2(y) = \frac{2 -1}{2}[/tex]
[tex]\sin^2(y) = \frac{1}{2}[/tex]
Square roots of both sides
[tex]\sin(y) = \frac{1}{\sqrt2}[/tex]
Rationalize
[tex]\sin(y) = \frac{\sqrt2}{2}[/tex]
So, we have:
[tex]\sin(x) = \frac{1}{2}[/tex] [tex]\cos(x) = \frac{\sqrt 3}{2}[/tex]
[tex]\cos(y) = \frac{\sqrt 2}{2}[/tex] [tex]\sin(y) = \frac{\sqrt2}{2}[/tex]
[tex]\tan(x) = \sin(x) \div \cos(x)[/tex]
[tex]\tan(x) = \frac{1}{2} \div \frac{\sqrt 3}{2}[/tex]
Rewrite as:
[tex]\tan(x) = \frac{1}{2} * \frac{2}{\sqrt 3}[/tex]
[tex]\tan(x) = \frac{1}{\sqrt 3}[/tex]
Rationalize
[tex]\tan(x) = \frac{\sqrt 3}{3}[/tex]
Similarly
[tex]\tan(y) = \sin(y) \div \cos(y)[/tex]
[tex]\tan(y) = \frac{\sqrt 2}{2} \div \frac{\sqrt 2}{2}[/tex]
[tex]\tan(y) = 1[/tex]
Lastly,
[tex]\tan(x + y)= \frac{\tan(x) + \tan(y)}{1 - \tan(x) \cdot \tan(y)}[/tex]
[tex]\tan(x + y)= \frac{\frac{\sqrt3}{3} + 1}{1 - \frac{\sqrt3}{3} \cdot 1}[/tex]
[tex]\tan(x + y)= \frac{\frac{\sqrt3}{3} + 1}{1 - \frac{\sqrt3}{3}}[/tex]
Combine fractions
[tex]\tan(x + y)= \frac{\frac{\sqrt3+3}{3}}{\frac{3 - \sqrt3}{3}}[/tex]
Cancel out 3
[tex]\tan(x + y)= \frac{\sqrt3+3}{3 - \sqrt3}[/tex]
Using a calculator
[tex]\tan(x+y) = 3.73[/tex]

I think you want to convert binary to hex.
Hexadecimal or "hex" is a numbering system which uses 16 different numerals. We saw that decimal used ten numerals from 0 to 9. Hex expands on this by adding six more, the capital letters A, B, C, D, E and F.
0...1...2...3...4...5...6...7...8...9...A...B...C...D...E...F
Steps to Convert Binary to Hex
1. Start from the least significant bit (LSB) at the right of the binary number and divide it up into groups of 4 digits. (4 digital bits is called a "nibble").
2.Convert each group of 4 binary digits to its equivalent
hex value .
3.Concatenate the results together, giving the total hex number.

Give examples of applications that access files by each of the following methods:
+ Sequentially.
+ Random.
Answer:
Explanation:
Usually, applications would have the capability of using either one of these options. But for the sake of the question here are some that usually prefer one method over the other.
Any program that targets an API usually uses Sequential access. This is because API's contain all of the data as objects. Therefore, you need to access that object and sequentially navigate that object to the desired information in order to access the data required.
A music application would have access to an entire folder of music. If the user chooses to set the application to randomly play music from that folder, then the application will use a Random Access method to randomly choose the music file to load every time that a song finishes.

An organization needs to integrate with a third-party cloud application. The organization has 15000 users and does not want to allow the cloud provider to query its LDAP authentication server directly. Which of the following is the BEST way for the organization to integrate with the cloud application?
a. Upload a separate list of users and passwords with a batch import.
b. Distribute hardware tokens to the users for authentication to the cloud
c. Implement SAML with the organization's server acting as the identity provider.
d. Configure a RADIUS federation between the organization and the cloud provider
Answer:
The BEST way for the organization to integrate with the cloud application is:
c. Implement SAML with the organization's server acting as the identity provider.
Explanation:
Implementing SAML (Security Assertion Markup Language) integrations will provide more security to the organization (identity provider) as users' credentials are exposed to fewer parties. SAML authenticates the users to the cloud application provider. SAML enables the organization to pass authorization credentials to the service provider by transferring the users' identities to the service provider.

What is one advantage and disadvantage of designing a support security that might be based on a centralized model, where all sensitive information is stored in one secure place, or a distributed model, where information is spread around in many different places?
Let a be an int array and let i and j be two valid indices of a, a pair (i,j) with i a[j]. Design a method that counts the different pairs of indices of a in disarray. For example, the array <1,0,3,2> has two pairs in disarray.
Answer:
Code:-
#include <iostream>
using namespace std;
int main()
{
// take array size from user
int n;
cout << "Enter array size:";
cin >> n;
// Declare array size with user given input
int a[n];
// take array elements from user & store it in array
cout << "Enter array elements:";
for(int i=0 ; i < n ; i++){
cin >> a[i];
}
/* ----- Solution Starts ----- */
// i & j for checking disarray & count is for counting no. of disarray's
int i=1, j=0, count=0;
for(int k=0; k < n ; k++){
if(a[i] > a[j]){
// if disarray found then increament count by 1
count++;
}
// increament i & j also to check for further disarray's
i++;
j++;
}
// Print the disarray count
cout << "Pairs of disarray in given array:" << count;

A sinewave has a period (duration of one cycle) of 645 μs. What is the corresponding frequency of this sinewave, in kHz, expressed to 3 significant figures?
please help me figure this out I am so confused
The corresponding frequency of this sinewave, in kHz, expressed to 3 significant figures is: 155 kHz.
Given the following data:
Period = 645 μsNote: μs represents microseconds.
Conversion:
1 μs = [tex]1[/tex] × [tex]10^{-6}[/tex] seconds
645 μs = [tex]645[/tex] × [tex]10^{-6}[/tex] seconds
To find corresponding frequency of this sinewave, in kHz;
Mathematically, the frequency of a waveform is calculated by using the formula;
[tex]Frequency = \frac{1}{Period}[/tex]
Substituting the value into the formula, we have;
[tex]Frequency = \frac{1}{645\; * \;10^{-6}}[/tex]
Frequency = 1550.39 Hz
Next, we would convert the value of frequency in hertz (Hz) to Kilohertz (kHz);
Conversion:
1 hertz = 0.001 kilohertz
1550.3876 hertz = X kilohertz
Cross-multiplying, we have;
X = [tex]0.001[/tex] × [tex]1550.39[/tex]
X = 155039 kHz
To 3 significant figures;
Frequency = 155 kHz
