Answer:

HELLO Hello thank you for your points...

b. Create a Room class with the instance variables int numBeds, and boolean hasBath. Create a subclass Suite of Room which will inherit the Instance variables of Room and has an additional instance variable int numSubrooms.

In object-oriented program designs, applications are split into sub-tasks and each sub-task is designed by creating as one or more classes to model it. This allows for flexibility and extensibility among other things.

In the case of the large hotel, two classes are of utmost importance:

i. the Room class to hold information about the number of beds in the room and whether or not the room has a bath.

ii. the Suite class to hold, in addition to the information held by the Room class, information about the number of sub-rooms in the suite.

To apply the concept of object-oriented design, since the suite is a special type of room, the Room class will serve as the super class while the Suite class which contains extra information will serve as the subclass inheriting all the properties of the Room class. Therefore the Suite will have all the properties of the Room and also its own special property - number of sub-rooms in this case.

Answer:

True

Answer:

#! /usr/bin/bash

echo $[$1**$2]

Explanation:

(a) The first line of the code is very important as it tells the interpreter where the bash shell is located on the executing computer.

To get this on your computer, simply:

1. open your command line

2. type the following command: which bash

This will return the location where the bash shell is. In this case, it returned

/usr/bin/bash

(b) The second line is where the actual arithmetic takes place.

The variables $1 and $2 in the square bracket are the first and second arguments passed from the command line. The ** operator raises the left operand (in this case $1) to the power of the second operand (in this case $2).

Then, the echo statement prints out the result.

(c) Save this code in a file named as pow.sh then run it on the command line.

For example, if the following is run on the command line: ./pow.sh 2 3

Then,

the first argument which is 2 is stored in $1 and;

the second argument which is 3 is stored in $2.

The arithmetic operator (**) then performs the arithmetic 2^3 which gives 8.

Answer:

the default frame rate is based on the frame rate of the display ( here also called *refresh rate" which is set to 60 frames per second on the most computers. A frame rate of 24 frames per second (usual for movies) or above will be enough for smooth animations

Answer:

Part a: The tag lists the

(voltage)

(V) that the appliance runs at and its

(power)

in watts (W). According to the tag, Dorian's blender uses  (120)

watts of power.

so your answers are voltage, then power, then 120.

c.

b.

b.

Part B:

One appliance that uses less power Then I blender would probably be a microwave. This is because you need to have electricity moving rapidly to move the blades in a blender compared to the microwave which you just need to keep a steady pace. One appliance that I think would use more power than a blender would definitely be an oven. This is because It does use steady current power just like the microwave but it uses it for way longer which takes up more power than rapid power in a blender for a short time.

Explanation:

For example, 150 watts (blender) and 300 watts (oven) have a 150-watt difference, sort of like subtraction in some cases!

Explanation:

Answer:

The program is as follows:

#include <bits/stdc++.h>

#include <iostream>

using namespace std;

int main(){

  list <int> myList;

  for(int i=0;i<100;i++){  

      myList.push_back(rand()%100);       }

   list <int> :: iterator it;

   cout<<"Forward: ";

   for(it = myList.begin(); it != myList.end(); ++it){

       cout <<*it<<" ";    }

   cout<<"\nReversed: ";

   std::copy(myList.rbegin(),myList.rend(),std::ostream_iterator<int>(std::cout, " "));

        myList.sort();  

   cout<<"\nSorted: ";

   for(it = myList.begin(); it != myList.end(); ++it){

       cout <<*it<<" ";    }

   return 0;

}

Explanation:

This declares the list

  list <int> myList;

The following iteration generates 100 random integers into the list

  for(int i=0;i<100;i++){  

      myList.push_back(rand()%100);       }

This initializes an iterator

   list <int> :: iterator it;

This prints the header "Forward"

   cout<<"Forward: ";

This iterates through the list and prints it in order

   for(it = myList.begin(); it != myList.end(); ++it){

       cout <<*it<<" ";    }

    This prints the header "Reversed"

   cout<<"\nReversed: ";

This uses ostream_iterator to print the reversed list

   std::copy(myList.rbegin(),myList.rend(),std::ostream_iterator<int>(std::cout, " "));

This sorts the list in ascending order

        myList.sort();

This prints the header "Reversed"  

   cout<<"\nSorted: ";

This iterates through the sorted list and prints it in order

   for(it = myList.begin(); it != myList.end(); ++it){

       cout <<*it<<" ";    }

   public static void main(String[] args) {

       int jagged[][] = new int[5][];

       int element = 1;

       for(int i=0; i<5; i++){

           jagged[i] = new int[i+1]; // creating number of columns based on current value

           for(int x = 0; x < jagged[i].length; x++) {

               jagged[i][x] = element;

               element += 1;

           }

       }

       System.out.println("Jagged Array elements are: ");

       for ( int[] x : jagged) {

           for (int y : x) {

               System.out.print(y + " ");

           }

           System.out.println(' ');

       }

       }

   }

1. Worldwide Web: In computing, WWW simply means World Wide Web. The world wide web was invented by Sir Tim Berners-Lee in 1990 while working with the European Council for Nuclear Research (CERN); Web 2.0 evolved in 1999. Basically, WWW refers to a collection of web pages that are located on a huge network of interconnected computers (the Internet). Also, users from all over the world can access the world wide web by using an internet connection and a web browser such as Chrome, Firefox, Safari, Opera, etc.

In a nutshell, the World Wide Web is an information system that is generally made up of users and resources (documents) that are connected via hypertext links.

2.E-mail: An e-mail is an acronym for electronic mail and it is a software application or program designed to let users send and receive texts and multimedia messages over the internet.

It is considered to be one of the most widely used communication channel or medium is an e-mail (electronic mail).

3. Powerline networking: this is a wired networking technology that typically involves the use of existing electrical cables in a building to connect and transmit data on network devices through powerline network adapters.

4. Cable: this include network cables such as CAT-5, CAT-6 and fiber optic cables used for connecting and transmitting signals between two or more network devices.

Answer:

The result of executing the code is 24.

Explanation:

Factorial of a number:

The factorial of a number is the multiplication of a number by all it's previous numbers until one. For example:

0! = 1

1! = 1

2! = 2*1 = 2

3! = 3*2*1 = 6

4! = 4*3*2*1 = 24

In this question:

This is a C++ code, which is a recursive function to calculate a factorial of a number.

The input, given by factorial(4), is 4, so the result of executing the code is 24.

cout << n << '*'; factorial(n-1);

This means for each input, until n = 1, the output is the factorial of the number. This is the recursive function.

Answer:

There are way in separating mixtures of chlorides salts such as that of sodium chloride and ammonium chloride. It can be done by crystallization, filtration or sublimation. If we want to separate the mixture, we have to heat up to 330-350 degrees Celsius and collect the gas that will be produced.

Answer:

About 2.5 seconds.

Explanation:

The speed of radio waves is 299,750 km/s whereas the distance between moon and earth is 384,400 km. By dividing speed of radio waves over the distance of moon and earth, we get 1.22 seconds of time from one side or in other words the person on the moon receives message in 1.22 seconds from the earth and the person on the earth receives a response from the moon in also 1.2 seconds so total time taken by the sender in receiving response from the moon is 2.5 to 3 seconds.

Answer:

Customer Number

Explanation:

Answer:A.)Say you have a 1 Mbps Internet connection. With such a connection speed, you might expect to download files at a rate of around 1 MB per second, but when you actually download a file, the download speed only reaches up to 100 – 120 KB per second.

B.)File Size In Megabytes / (Download Speed In Megabits / 8) = Time In Seconds. A 15 Megabyte file, downloading at 10 Megabits per second: 15 / (10/8) = 12 seconds.

C.) If the file size is 100mb and downloading speed is 54Mbps So the total time taken is 00:00:15.
