Answer:
TRUE
Explanation:
Write a function to calculate the distance between two points Distance( x1, y1,x2.2) For example Distance(0.0,3.0, 4.0.0.0) should return 5.0 Use the function in main to loop through reading in pairs of points until the all zeros are entered printing distance with two decimal precision for each pair of points.
For example with input
32 32 54 12
52 56 8 30
44 94 4439 6
5 19 51 91 7.5
89 34 0000
Your output would be:__________.
a. 29.73
b. 51.11
c. 55.00
d. 73.35
e. 92.66
Answer:
The function in Python3 is as follows
def Distance(x1, y1, x2, y2):
dist = ((x1 - x2)**2 +(y1 - y2)**2)**0.5
return dist
Explanation:
This defines the function
def Distance(x1, y1, x2, y2):
This calculates distance
dist = ((x1 - x2)**2 +(y1 - y2)**2)**0.5
This returns the calculated distance to the main method
return dist
The results of the inputs is:
[tex]32, 32, 54, 12 \to 29.73[/tex]
[tex]52,56,8,30 \to 51.11[/tex]
[tex]44,94,44,39\to 55.00[/tex]

1.Write a Java program to solve the following problem using modularity. Write a method that rotates a one-dimensional array with one position to the right in such a way that the last element becomes the first element. Your program will invoke methods to initialize the array (random values between 1 and 15) print the array before the rotation, rotate the array, and then print the array after rotation. Use dynamic arrays and ask the user for the array size. Write your program so that it will generate output similar to the sample output below:
Answer:
Explanation:
The following code is written in Java and it asks the user for the size of the array. Then it randomly populates the array and prints it. Next, it rotates all the elements to the right by 1 and prints the new rotated array.
import java.util.ArrayList;
import java.util.Arrays;
import java.util.Random;
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
Random r = new Random();
Scanner in = new Scanner(System.in);
System.out.println("Enter Size of the Array: ");
int arraySize = in.nextInt();
ArrayList<Integer> myList = new ArrayList<>();
for (int x = 0; x < arraySize; x++) {
myList.add(r.nextInt(15));
}
System.out.println("List Before Rotation : " + Arrays.toString(myList.toArray()));
for (int i = 0; i < 1; i++) {
int temp = myList.get(myList.size()-1);
for (int j = myList.size()-1; j > 0; j--) {
myList.set(j, myList.get(j - 1));
}
myList.set(0, temp);
}
System.out.println("List After Rotation : " + Arrays.toString(myList.toArray()));
}
}

What is the difference between a worm and a typical virus?
A) Worms are a type of spyware; viruses are a type of malware.
B) Worms are impossible to remove; viruses can be tracked and removed.
C) Worms are stronger than viruses; viruses are stronger than spam.
D) Worms travel independently of human action; viruses require human actions.
Answer:
Option C
Explanation:
Option A is incorrect as Worm is a form of malware
Option B is incorrect because antivirus can remove all forms of malware
Option C is correct because a worm is more problematic as compared to the virus. Also, viruses are weaker than worm because they need a host file to run but a worm can work independently.
Option D is also incorrect because both are able to self replicate.

How should you add a appointment to your outlook calendar
answer:
press on the date thing
You own a small hardware store. You have been in business since 1995 and have always been profitable. You’ve never seen a need to do any marketing or advertising since you were able to stay profitable without those things. Plus, you lack any real understanding of how to use technology and it makes you anxious just thinking about technology or social media. However, your son just graduated from college and came home to live with you for the summer before he starts his new marketing manager job at a big firm. He tells you that you are probably losing a big share of the market by avoiding technology and social media. He also says that many of these items can be implemented very easily, and he would volunteer to continue to manage the social media sites in his spare time even after he starts his new job.

Requirements description:
Assume you work part-time at a Cafe. As the only employee who knows java programming, you help to write an ordering application for the store.
The following is a brief requirement description with some sample output.
1. Selecting Breakfast or Lunch(5 points)
When the program starts, it first shows option Breakfast or Lunch. A sample output is as follows.
=== Select Breakfast or Lunch: ===
1. Breakfast
2. Lunch
You are supposed to validate the input.
If the user enters a letter or a number not between 1 and 2, the user will see an error message.
A sample output for invalid number is as follows.
Select Breakfast or Lunch [1, 2]: 0
Error! Number must be greater than 0.
Select Breakfast or Lunch [1, 2]:
2. Selecting Coffee (20 points)
When the program continues, it shows a list/menu of coffee and their prices, then asks a user to select a coffee by entering an integer number. A sample output is as follows.
=== Select Coffee: ===
1 Espresso $3.50
2 Latte $3.50
3 Cappuccino $5.00
4 Cold Brew $3.00
5 Quit Coffee selection
Select a coffee [1, 5]:
You are supposed to validate the input.
If the user enters a letter or a number not between 1 and 5, the user will see an error message.
A sample output for invalid number is as follows.
Select a coffee [1, 5]: 0
Error! Number must be greater than 0.
Select a coffee [1, 5]:
In your program, you can hard-code the information for coffee (i.e., coffee names and prices) shown above, such as "1 Espresso $3.50" and use the hard-code price, such as 3.50, for calculation of a total price of the order.
After the user makes a choice for coffe, such as 2 for Latte. The program continues asking for selecting a coffee so that the user can have multiple coffee orders. The user can enter "5" to quit coffee selection. A sample output is as follows.
=== Select Coffee: ===
1 Espresso $3.50
2 Latte $3.50
3 Cappuccino $5.00
4 Cold Brew $3.00
5 Quit Coffee selection
Select Coffee: [1, 5]: 2
=== Select Coffee: ===
1 Espresso $3.50
2 Latte $3.50
3 Cappuccino $5.00
4 Cold Brew $3.00
5 Quit Coffee selection
Select Coffee: [1, 5]: 5
3. Selecting Food (10 points)
After Coffee selection, the program shows food selection. A sample output is as follows.
=== Select Food: ===
1 Tuna Sandwich $10.00
2 Chicken Sandwich $10.00
3 Burrito $12.00
4 Yogurt Bowl $8.00
5 Avocado Toast $8.00
6 Quit Food selection
Select Food: [1, 6]: 1
Input validation is needed and works as before. Like Coffee selection which allows selecting multiple Coffee orders, food selection also repeats after the user enters a valid number between 1 and 5.
You hard-code the information for food shown above, such as "1 Tuna Sandwich $10.00" and use the hard-code price, such as 10.00, for calculation of the total price of the order.

Write a recursive method named factorial that accepts an integer n as a parameter and returns the factorial of n, or n!. A factorial of an integer is defined as the product of all integers from 1 through that integer inclusive. For example, the call of factorial(4) should return 1 * 2 * 3 * 4, or 24. The factorial of 0 and 1 are defined to be 1. You may assume that the value passed is non-negative and that its factorial can fit in the range of type int. Do not use loops or auxiliary data structures; solve the problem recursively.
Answer:
The function in Python is as follows:
def factorial(n):
if n == 1 or n == 0:
return n
else:
return n*factorial(n-1)
Explanation:
This defines the function
def factorial(n):
This represents the base case (0 or 1)
if n == 1 or n == 0:
It returns 0 or 1, depending on the value of n
return n
If n is positive, then this passes n - 1 to the factorial function. The process is repeated until n = 1
else:
return n*factorial(n-1)
Complete the sentence.

Answer:
C. Moving the statement in line 5 so that it appears between lines 2 and 3
Explanation:
Given
The attached procedure
Required
What should be modified
The problem in the procedure is on line 5
i.e. count = 0
This line is within the loop, and this means that the count variable is initialized to 0 each time the loop is repeated.
To solve this, the count variable has to be removed from the loop to somewhere before the loop.
Hence, option (c) is correct
Throughout our procedure, even though we proclaimed count = 0 inside the for loop, the count has been valued at 0.
After that, When a certain value is found equal to Val, the count has been incremented by 1. The count is set to 0 again in the next iteration, so at the end, if we found an element equivalent to Val 1, its real count has been returned.To get around this, we'll define count outside of the for loop to acquire the true count of instances of that specific value.Therefore, the answer is "Option C".

Answer:
Explanation:
The following code is written in Java. I created both versions of the program that was described in the question. The outputs can be seen in the attached images below. Both versions are attached as txt files below as well.
HTML tag that makes a text field used by javascript statement
CS160 Computer Science I In class Lab 10
Objective:
Work with dictionaries
Work with strings
Work with files
Assignment:
This program will read a file of English words and their Spanish translation. It then asks the user for an English word. If it exists in your dictionary the Spanish translation is displayed. If the English word does not exist in the dictionary the program states that the word does not exist in its list of words.
Specifics:
Create a text file, with one English word and a Spanish word per line, separated by a colon. You can create the language file using a text editor, you do not need to write a program to create this file. An example of the file might be:
one:uno
two:dos
three:tres
four:cuatro
five:cinco
six:seis
seven:siete
eight:ocho
nine:nueve
ten:diez
After reading the text file, using it to fill up a dictionary, ask the user for an English word. If the word exists, print out the Spanish version. If the word does not exist state that the word is not in your list. Continue this process of asking for a word until the user does not enter a word (just pressed Enter).
As you might have noticed, there is nothing in the program that limits this Spanish words. This program can be written to work with any translation, so feel free to make it be French, or German or any other language where you can come up with a list of translated words. You also are not limited to 10 words, that is just the list I came up with for the example. The number of key/values pairs that you have in your dictionary is basically limited by the memory in your computer.
Hints
You will need to determine if the key (the English word) exists in the dictionary. Use the in operator with the dictionary, or the get() method. Either can be used to avoid crashing the program, which happens if you attempt to use a key that does not exist.
An example of running the program might be:
Enter the translation file name: oneToTen.txt
> Enter an English word to receive the Spanish translation.
Press ENTER to quit.
Enter an English word: one
he Spanish translation is uno
Enter an English word: ten
The Spanish word is diez
Enter an English word: 5
I don’t have that word in my list.
Enter an English word: three
The Spanish word is tres
Answer:
The program in Python is as follows:
fname = input("Enter the translation file name: ")
with open(fname) as file_in:
lines = []
for line in file_in:
lines.append(line.rstrip('\n'))
myDict = {}
for i in range(len(lines)):
x = lines[i].split(":")
myDict[x[0].lower()] = x[1].lower()
print("Enter an English word to receive the Spanish translation.\nPress ENTER to quit.")
word = input("Enter an English word: ")
while(True):
if not word:
break
if word.lower() in myDict:
print("The Spanish word is ",myDict[word.lower()])
else:
print("I don’t have that word in my list.")
word = input("Enter an English word: ")
Explanation:
This prompts the user for file name
fname = input("Enter the translation file name: ")
This opens the file for read operation
with open(fname) as file_in:
This creates an empty list
lines = []
This reads through the lines of the file
for line in file_in:
This appends each line as an element of the list
lines.append(line.rstrip('\n'))
This creates an empty dictionaty
myDict = {}
This iterates through the list
for i in range(len(lines)):
This splits each list element by :
x = lines[i].split(":")
This populates the dictionary with the list elements
myDict[x[0].lower()] = x[1].lower()
This prints an instruction on how to use the program
print("Enter an English word to receive the Spanish translation.\nPress ENTER to quit.")
This prompts the user for an English word
word = input("Enter an English word: ")
This loop is repeated until the user presses the ENTER key
while(True):
If user presses the ENTER key
if not word:
The loop is exited
break
If otherwise, this checks if the word exists in the dictionary
if word.lower() in myDict:
If yes, this prints the Spanish translation
print("The Spanish word is ",myDict[word.lower()])
If otherwise,
else:
Print word does not exist
print("I don’t have that word in my list.")
Prompt the user for another word
word = input("Enter an English word: ")
