Answer:
public class Point
{
public int x;
public int y;
Point(int x,int y)
{
this.x=x;
this.y=y;
}
public static void main(String[] args)
{
Point p1=new Point(-2,3);
Point p2=new Point(3,-4);
System.out.println("distance:"+distance(p1,p2));
}
private static double distance(Point p1,Point p2)
{
return Math.sqrt(Math.pow(p2.x-p1.x, 2)+Math.pow(p2.y-p1.y, 2));
}
}
Explanation:
The java program defines the Point class and the public method 'distance' to return the total distance between the two quadrants passed to it as arguments (they are both instances of the Point class).
You can write a function to find Fibonacci numbers using recursion.
How do you find the next number?
add five to the previous number
add one to the previous number
multiply the two previous numbers
add the two previous numbers
Answer:
Add the two previous numbers
Explanation:
A recursive definition of the Fibonacci sequence would look like this, in python:
def fibonacci(n)
if n <= 1:
return n
else:
return(fibonacci(n-1) + fibonacci(n-2))
The cash register program will have items. For each item, the name and cost are saved. For a transaction, it will accept any number of items (not known in advance) and any number of payments of different payment types (not known in advance). For each transaction, it calculates the total including a 7% sales tax and keeps prompting for a payment until the total has been paid. It also determines if any change is required. Thus, a transaction is responsible for calculating the amount of money that needs to be paid, accepting money, and generating a receipt. A receipt holds information about a transaction so that it can display how much each item cost, how the transaction was paid for, etc. (see example outputbelow).Payment type includes CASH, DEBIT_CARD, CREDIT_CARDandCHECK. Each payment consists of an amount and payment type
Hints
1. All fields should be private.
2. The PaymentType class should be an enum class with values: CASH, DEBIT_CARD, CREDIT_CARD, CHECK
3. Payment type information should not print the enum directly
4. Use final to store the transaction for each receipt.
5. Output:
A. The values for subtotal, tax, total, and payment information are all aligned. You can achieve this by using the tab character '\t' in your Strings. The item lines do not need to be aligned.
B. Do not worry about only using 2 decimal places. Let Java decide how many decimal places to use.
6. Create a main class to house the main method. In the main method, create some items, a transaction, and display the receipt.
A. Example outputs
Example: Pay everything with one payment
Transaction listing the items and asking for payment:
Item 1: apple: 0.5

Write a program that calculates the amount of money in a savings account that earns a guaranteed yearly interest rate. The program will accept from the user the account is present value (i.e. what is in the savings account now), the annual interest rate (in a percentage), and the number of years the money will be left in the account (years). The program should display the savings account future value and the number of years the money will be left in the account.
Solution :
# Reading principle amount from user
[tex]$\text{accountPresentValue}$[/tex] = eval([tex]$\text{inpu}t("$[/tex]Enter principle amount: "))
# Reading time duration in number of year from user
years = eval(input("Enter time duration in number of year: "))
# Reading interest rate from user
annualInterestRate = eval(input("Interest rate: "))
# calculating futureValue using user input data
futureValue = accountPresentValue * (1 + annualInterestRate / 100) ** years
# printing calculated futureValue to console
print("Final balance =",futureValue)

What is used to prevent all vlans from going across a trunk?
In QBasic, create a number guessing challenge. Your program should generate a random number from 1-
100 (inclusive). Let the user guess a number. The program should let the user guess until they get the
correct number. After each input, the program should tell the user whether they guessed the correct
number, or if they guessed too high or too low. While the user is entering guesses, the program should
keep a count of the number of guesses that it takes to get the correct number. After the user guesses
the correct number, the program should congratulate the user and tell them how many guesses it took
them to get the correct number. By the way, if the user chooses carefully, they should be able to guess
the number within 7 tries. But, your program should still let the user keep guessing until they guess the
correct number

A license plate has 7 characters. Each character can be a capital letter or a digit except for 0. How many license plates are there in which no character appears more than once and the first character is a digit?
a. 9 P(35, 6)
b. 9 P(34,6)
c. 9.(35)^6
d. 9.(35)^6
Answer:
b. 9 P(34,6)
Explanation:
Since the 1st character of the number plate is the digit, therefore, there are nine possible ways to select them from digits 1 to 9.
And in the license plate there are 7 characters, the first character is counted before and the remaining 6 characters that can either be a digit or a letter has to be considered.
Now there are in total 34 symbols remaining form a total of 26 letters and 8 digits. They can be placed as 34x33x32x31x30x29 ways = P(34, 6) ways.
Therefore in total for all the characters there are 9 x P(34, 6) different ways.

Explanation:
Marketing can be defined as the process of developing promotional techniques and sales strategies by a firm, so as to enhance the availability of goods and services to meet the needs of the end users or consumers through advertising and market research. The pre-service strategies includes identifying the following target market, design, branding, market research, etc.
Market research can be defined as a strategic technique which typically involves the process of identifying, acquiring and analyzing informations about a business. It involves the use of product test, surveys, questionnaire, focus groups, interviews, etc.
Web analytics refers to a strategic process which typically involves the collection of data, as well as the study of user behavior in an attempt to enhance or boost market share and sales. It is divided into two main categories;
I. on-site Web analytics.
II. off-site Web analytics.
In this scenario, your tasks include identifying competitors, determining your company's market penetration and consulting market research sources. These tasks are examples of off-site Web analytics.
g Consider the turning point problem again, but this time you are given a sequence of at least three integers, which consists of a decreasing subsequence followed by an increasing subsequence. Using the divide and conquer technique, develop a recursive algorithm that finds the index of the turning point in the sequence (that is, the point where it transitions from a decreasing subsequence to an increasing subsequence). For example, in the sequence [43 30 16 10 7 8 13 22], the integer 7 is the turning point and its index is equal to 4 (assuming the starting index is 0). So, the algorithm should return 4
Answer:
Explanation:
The following code is written in Python, it creates a recursive function that takes in a list as a parameter, then compares the first two items in the list if the first is greater, it increases the index by one and calls the function again. This is done until the turning point is found, it then prints out the position of the turning point int the list.
def find_turning_point(list, x=0):
if list[x] > list[x + 1]:
x += 1
return find_turning_point(list, x)
else:
return "The turning point position is: " + str(x)

Explanation:
An organization requires secure configuration baselines for all platforms and technologies that are used. If any system cannot conform to the secure baseline, the organization must process a risk acceptance and receive approval before the system is placed into production. It may have non-conforming systems in its lower environments (development and staging) without risk acceptance, but must receive risk approval before the system is placed in production. Weekly scan reports identify systems that do not conform to any secure baseline. The application team receives a report with the following results:
Host Environment Baseline deviation ID(criticality)
NYAccountingDev Development
NYAccountingStg Staging
NYAccounting Prod Production 2633 (low), 3124 (high)
There are currently no risk acceptances for baseline deviations. This is a mission-critical application, and the organization cannot operate if the application is not running. The application fully functions in the development and staging environments. Which of the following actions should the application team take?
A. Remediate 2633 and 3124 immediately.
B. Process a risk acceptance for 2633 and 3124.
C. Process a risk acceptance for 2633 and remediate 3124.
D. Shut down NYAccounting Prod and investigate the reason for the different scan results.
Answer:
C. Process a risk acceptance for 2633 and remediate 3124.
Explanation:
There are various business risks. Some are inherited risks while other are risks are associated with nature of business. It is dependent on business owners that they want to accept risk or mitigate the risk. Risk acceptance is based on the strategy of the management. In the given scenario Accounting Prod Production has low risk 2633 which is accepted while 3124 is high risk which is remediated.

The bookstore keeps track of which books it has in its inventory, and the books purchased by each customer
a. What are the objects in your object- oriented Solution?
b. What are the interactions between objects in your solution?
c. Which objects "have" other objects?
d. Which Objects "Use" other objects?
e. Which objects are other objects?
Answer:
Explanation:
a. In this scenario, the best solution would have an Object of Traditional Books, CD, Music, Bookstore and Customer.
b. All five objects would be able to be called by the main program loop and the Customer Object would call upon and use either the Books or CD object, While the Bookstore object would call upon all of the other objects.
c. Both the Bookstore object and Customer object will "have" other objects as the Bookstore needs to hold information on every Book or CD in the Inventory. While the Customer object would call upon the Book and CD object that they are purchasing.
d. The Music Object will extend the CD object and use information on the CD object as its parent class.
e. Since the Music Object extends the CD object it is also considered a CD since it is in CD format like the Books on CD and therefore is both objects.
How does an online discussion group differ from one that is held face-to-face?
There is no need for group roles when holding online meetings.
Online discussion groups do not allow members to develop critical-thinking skills.
Group members are more likely to bond together as a group online than they would when meeting face-to-face.
Facilitating an online conversation may require even more work, so that participants continue engaging with one another online.
Answer: they always will have a different thinkage from others
Explanation:Some people need actual in person learning for better grades it also keeps them from getting distracted easily, they have different brains in everyone in the world everyone thinks, acts and talks in different ways some people dont need in person school because they would rather be online wich are both ok so yes they do bond together online but better in person.
Online discussion group differ from one that is held face-to-face as Group members are more likely to bond together as a group online than they would when meeting face-to-face. Thus, option C is correct.
What is software organization?A system that defines how specific activities, in this case, the software development process, are directed to achieve corporate goals is referred to as an organizational structure. These activities could include putting rules, roles, and responsibilities in place.
There are four basic modes of collaboration, as illustrated by the exhibit "The Four Ways to Collaborate": a closed and authoritarian network (an elite circle), an open and hierarchical connectivity (an innovation mall), an open and flat network (an innovation community), and a shuttered and flat network (a consortium).
Groupware is software that allows a group of people to work together on the same system or application, regardless of where they are. Email, newsgroups, and many more are examples of groupware applications.
Thus, option C is correct.

Lists are an example of a data abstraction.
A data abstraction can often contain different types of elements. It also provides a separation between the abstract properties of a data type (integer, boolean, string) and the concrete details of its representation. Basically, it doesn’t matter that the type are different!
Create an empty list. Append the integer 3, a string of "hello" and a boolean of False into the list. Print out each index individually. Now, remove the number 3 and False from the list.
Finally, print out the list again.
Answer:
Explanation:
The following Python code does exactly as requested. Once the list is created and the elements are added to it, it uses a for loop to print out each element individually. Then once the loop is over it removes the 3 and False elements from the list and creates another for loop to print the remaining element(s) individually again.
my_list = []
my_list.append(3)
my_list.append("hello")
my_list.append(False)
for x in my_list:
print(x)
my_list.remove(3)
my_list.remove(False)
for x in my_list:
print(x)

Antivirus is a program that detects error.True or False.
Answer: false
Explanation:
Because it isn't true.
You were just hired as an IT Specialist for Smalltown School District. Your first assignment is to review a problem area& in student records processing. It seems that the program currently used to compute student grade point averages and class rankings runs terribly slow and as a result end of year reports are habitually late. Your are asked to come up with a list of items that should be checked in order to determine if a modification to code is in order. The IT department head is asking you to do this without the opportunity to actually see the current application/programs in use. What questions would you ask about the current code? What areas of code would you look at? What would you need to know about the student data?
Answer:
Explanation:
There are various questions that you can ask in this scenario, such as
What grading policies are being implemented?
How many student grades are being calculated by the program?
What is the requirements for a student to pass?
All of these questions would allow you to get an idea of how extensive the code may be and its complexity. Once you know this you would look at the code revolving around actually looping through the data and doing the necessary calculations. You can then determine how to manipulate the code and make it much more efficient.
You would also need to know how the student data is being saved, which will help determine if it is the best data structure for saving this type of data or if it can be replaced in order to maintain the data secure while increasing the speed of the program. Mainly since this information needs to be continuously used from the data structure.
