First, allow the user to enter a numeric value representing how many names they would like to enter. Next, create an array with its size based on that value. Once the array is created, allow the user to enter in names until the array is full. Again, use a for loop to do this

//Scanner class is imported to allow program receive user input

import java.util.Scanner;

//The Solution class is defined

public class Solution {

   // main method that begin program execution is declared

   public static void main(String args[]) {

       // Scanner object scan is created

       Scanner scan = new Scanner(System.in);

       // A prompt is displayed to the user

       // the prompt asked the user to enter a number

       System.out.println("Enter a number: ");

       // the user input is assigned to a variable size

       int size = scan.nextInt();

       // an empty string name is initialized

       String name = "";

       // A string array called names is initialized

       // have the inputed number as size

       String names[] = new String[size];

       // A for-loop that allow a user to enter name

       // and fill the array with it

       for(int i = 0; i < size; i++){

           // A prompt is displayed asking the user to enter a name

           System.out.println("Enter a name: ");

           // the received input is assigned to name

           name = scan.next();

           // name is assigned to an index

           names[i] = name;

       }

       // A blank line is printed for clarity

       System.out.println();

       // for-loop to loop the array and print the entire element

       for(int i = 0; i < size; i++){

           System.out.println(names[i]);

       }

   }

}

Step-by-step explanation:

The program is well commented and written in Java. A sample image of program output during execution is attached.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

whatvare the choices
