George and Miguel are considering opening up a shoe store but first need to do market research. Which one of these is NOT part o

Answer:

Here is the C++ code:

#include <iostream> //for utilizing input and output functions

using namespace std; //for defining objects cin cout

int main(){ //beginning of the main function

     

   double risingLevel; //declares a variable of type double to store the rising level

   cin>>risingLevel; //captures the risingLevel input from the user

   

   cout<<"Level: "<<risingLevel<<endl; //outputs the rising level

   cout << "Years: 5, Rise: " << risingLevel * 5<<endl; //outputs the increase in ocean level over 5 years

   cout << "Years: 10, Rise: " << risingLevel * 10<<endl; //outputs the increase in ocean level over 10 years

   cout << "Years: 50, Rise: " << risingLevel * 50<<endl; //outputs the increase in ocean level over 50 years

}

Explanation:

The functioning of the program is as follows:

Supposing the user inputs a rising level of 2.1, then,

risingLevel = 2.1

At that point, the first print statement (cout):

cout<<"Level: "<<risingLevel<<endl; outputs the value of risingLevel to the display. Therefore, this line shows:

Level: 2.1

Next, the program proceeds to the following statement:

   cout << "Years: 5, Rise: " << risingLevel * 5<<endl;

which calculates the increase in ocean levels for a duration of 5 years using the equation:

risingLevel * 5 = 2.1 * 5 = 10.5

It subsequently shows the calculated result on the display. So, this line shows:

Years: 5, Rise: 10.5 Then, the control shifts to the next statement:

   cout << "Years: 10, Rise: " << risingLevel * 10<<endl;

that computes the rise in ocean levels over a span of 10 years using the equation:

risingLevel * 10 = 2.1 * 10 = 21

It then showcases the calculated figure on the output screen. Thus, the output is:

Years: 10, Rise: 21

Next, the program control progresses to this statement:

   cout << "Years: 50, Rise: " << risingLevel * 50<<endl;

which determines the rise in ocean levels for a duration of 50 years using the equation:

risingLevel * 50 = 2.1 * 50 = 105

This then displays the computed result on the output screen, leading to the output:

Years: 50, Rise: 105 Consequently, the complete output from the program will be:

Level: 2.1 Years: 5, Rise: 10.5

Years: 10, Rise: 21

Years: 50, Rise: 105

public static int factorial(int n) { if (n >= 1 && n <=12) { if (n == 1) return 1; else return n * factorial(n - 1); } else return -1; } Explanation: The factorial method takes a single integer n as input. It checks if n is within the range of 1 to 12. If it is, it further checks if n equals 1. If it is indeed 1, it returns 1 as the factorial. Otherwise, it recursively calls itself with n decreased by 1, multiplying the result by n. If n is outside this range, the method returns -1 indicating the input is invalid.

The correct option is "video". This is because video formats are more compact compared to text or songs, which are also subjected to lossy compression. The advantages of video encoding are more effective in handling lossy compression, and since text and audio require less information, they compress better. Videos and images necessitate high quality, therefore they are also more suitable for lossy compression.
