Write a method that prints on the screen a message stating whether 2 circles touch each other, do not touch each other or intersect. The method accepts the coordinates of the center of the first circle and its radius, and the coordinates of the center of the second circle and its radius.

The header of the method is as follows:

public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2)


Hint:

Distance between centers C1 and C2 is calculated as follows:
d = Math.sqrt((x1 - x2)2 + (y1 - y2)2).

There are three conditions that arise:

1. If d == r1 + r2
Circles touch each other.
2. If d > r1 + r2
Circles do not touch each other.
3. If d < r1 + r2
Circles intersect.

Answer:

C15H24O

Explanation:

n(C) = 4.497 g/44g/mol = 0.1022

Mass of C = 0.1022 × 12 = 1.226 g

n(H) = 1.473g/18 g/mol = 0.0823 ×2 moles = 0.165 moles

Mass of H = 0.0823 × 2 ×1 = 0.165g

Mass of O= 1.501 -(1.226 + 0.165)

Mass of O= 0.11 g

Number of moles of O = 0.11g/16g/mol = 0.0069 moles

Dividing through by the lowest ratio;

0.1022/0.0069, 0.165/0.0069, 0.0069/0.0069

Answer:

The java program is as follows:

import java.util.*;

public class Main{

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

 Random r = new Random();

 int x, y;

 x = input.nextInt();  

 y = input.nextInt();

 int[][] Array2D = new int[x][y];

 for(int i = 0; i < x ; i++){

     for(int j = 0; j < y; j++){          Array2D[i][j] = r.nextInt(9) + 1;      }

 }

 for(int i = 0; i < x ; i++){

     for(int j = 0; j < y; j++){          System.out.print(Array2D[i][j]+" ");      }

     System.out.println();

 }

 for(int i = 0; i < x ; i++){

     for(int j = 1; j < y; j+=2){          System.out.print(Array2D[i][j]+" ");      }

     System.out.println();

 }

}

}

Explanation:

This creates a random object

 Random r = new Random();

This declares x and y as integers

 int x, y;

This gets input for x

 x = input.nextInt();  

This gets input for y

 y = input.nextInt();

This declares the 2D array

 int[][] Array2D = new int[x][y];

The following iteration populates the array with integers 1 to 9

 for(int i = 0; i < x ; i++){

     for(int j = 0; j < y; j++){          Array2D[i][j] = r.nextInt(9) + 1;      }

 }

The following iteration prints all elements of the array

 for(int i = 0; i < x ; i++){

     for(int j = 0; j < y; j++){          System.out.print(Array2D[i][j]+" ");      }

     System.out.println();

 }

The following iteration prints all elements on the even column

 for(int i = 0; i < x ; i++){

     for(int j = 1; j < y; j+=2){          System.out.print(Array2D[i][j]+" ");      }

     System.out.println();

>>> B = [35, 'cat', 'blue')

>>> C = [12, 'fish', 'green']

>>> E = [A, B, C]

the value of E[0][1]

Here, square boxes is used to select the value at E[0] ; the output is then used to select the value at index 1 of E[0] output.

Note that, indexing starts at 0; hence first list element is 0, then, 1, 2, and so on.

At

E[0] ; list E, index 0 (first element in the list) , gives an output A

Then, A[1] ; list A, index 1 (second element in the list) gives 'dog'

Answer:

The function is as follows:

def number_of_pennies(dollars,pennies=0):

   return dollars*100+pennies

Explanation:

This defines the function

def number_of_pennies(dollars,pennies=0):

This returns the number of pennies

   return dollars*100+pennies

Note that, if the number of pennies is not passed to the function, the function takes it as 0

Answer:

Code is given as:-

#number_of_pennies function with one default argument with pennies as 0 when no pennies parameter is given

def number_of_pennies(dollars,pennies = 0):

  pennies = dollars*100 + pennies #one dollar equals 100 pennies so calculate total pennies with this formula

  return pennies #return total pennies

print(number_of_pennies(int(input()),int(input()))) #both Dollars and pennies

print(number_of_pennies(int(input()))) #Dollars only

Answer and Explanation:

Using MATLAB code:

Function Lkm = Lkm-mpgToLpkm (mpg)

Lkm= mpg*1.60934/3.78541;

Lkm= Lkm^(-1);

Lkm= Lkm*100;

%the code above defines a function Lkm and takes argument/input to its parameter mpg(miles per gallon) and then returns/output Lkm which is the litres per kilometers conversion from miles per gallon input.

Answer:

Acronis True Image is the one I would recommend out of these mentioned online backup services.

Explanation:

The evaluations and reviews of each of the online backup services are as follows:

a. iDrive

For this, we have:

Speed = 60% - fair

Security = 100% - excellent

Privacy = 88% - very good

Features = 95% - excellent

Pricing = 85% - Very good

Because of its various features, pricing, and usability, IDrive reviews suggest that it is a very efficient online backup solution. However, there have been complaints concerning its speed and the fact that there are no monthly plans available.

b. Carbonite

For this, we have:

Speed = 60% - fair

Security = 100% - excellent

Privacy = 87% - very good

Pricing = 85% - very good

File backup and restoration = 75% - good

Carbonite reviews reveal that it is simple to use and provides limitless backup for one device. The main drawback is that it has extremely poor backup speeds.

c. Acronis True Image

This is fast, simple and intuitive

It has complete control over the backup updates, including how and when they occur.

It is not expensive.

Acrnonis True image is a powerful backup storage service. It enables data and file backup and restoration from USB drives.

Many reviewers of Acrnonis True image have stated that they have had no issues with its service, that it is worth purchasing, and that there are no concerns.

d. Backblaze

For this, we have:

Speed = 75% - good

Security = 75% - good

Privacy = 70% - decent

Pricing = 100% - excellent

Support = 95% - excellent

Features = 65% - decent

File back-up and restoration = 70% - decent

Backblaze is one of the most popular internet backup services. This storage service, however, does not allow for ustomization.

Recommendation

Acronis True Image is the one I would recommend out of these mentioned online backup services. This is due to the fact that it delivers a large amount of accurate and high-quality data storage. It is quick, simple and intuitive, which is what most people care about. Furthermore, reviewers have stated that this service is quite effective and that there have been very few issues with it. The other services demonstrate that their services have flaws, such as lack of customization and slowness.

Answer:

total = 0

k = 1

while k <= 50:

total += k**2

k += 1

print(total)

Explanation:

Note: There some errors in the question. The correct complete question is therefore provided before answering the question as follows:

Use the variables k and total to write a while loop that computes the sum of the squares of the first 50 counting numbers, and associates that value with total. Thus your code should associate 1*1 + 2*2 + 3*3 +... + 49*49 + 50*50 with total. Use no variables other than k and total.

The answer is now explained as follows:

# Initialize k which is the number of term

k = 1

# Initialize total which is the sum of squares

total = 0

# Loop as long as k is less than or equal to 50.

while (k <= 50):

# Add the square of k to total in order to increase it

total = total + k * k

# Increase the value of k by one.

k += 1

# Finally, output total

print (total)

SSH, HTTPS and SMTP

Explanation:

Data theft can be defined as a cyber attack which typically involves an unauthorized access to a user's data with the sole intention to use for fraudulent purposes or illegal operations. There are several methods used by cyber criminals or hackers to obtain user data and these includes DDOS attack, SQL injection, man in the middle, phishing, etc.

Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.

Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.

Hence, SSH, HTTPS and SMTP are considered as secure network protocols.

HTTPS is acronym for Hypertext Transfer Protocol Secure while SSL is acronym for Secure Sockets Layer (SSL).

SMTP is an acronym for Simple Mail Transfer Protocol and it uses the standard port number of 25 to provide clients with requested services.

Answer:

Select SUM(HOURS), SUM(CHARGES) from employees

Explanation:

The table structure is not given. So, I will assume that the table name is "employees", the columns to retrieve are "hours" and "charges"

Having said that, the function to retrieve the total of column is the sum() function.

So, the query is as follows:

Select ----> This means that the query is to retrieve from the table

SUM(HOURS), SUM(CHARGES) --- This represent the records to retrieve

from employees ---- This represents the table to retrieve from.

The complete method is as follows:

public List buildList(List L) {  

 L.insert(30);

 L.insert(23);

 L.insert(19);

 L.insert(4);  

   return L; }

Explanation:

To complete the method, we make use of the insert() function.

This inserts elements of the list into list L. However, we have to start from the last element (i.e. in descending order)

So, the explanation is as follows:

 L.insert(30); --- This inserts the last element

Continue inserting in descending order

 L.insert(23);  

 L.insert(19);

Until the first list element is inserted

 L.insert(4);

This returns the filled list L  

   return L;

A class of ArrayList is a redimensionable array in java. During built-in arrays, ArrayLists can dynamically change their size. Elements can be added and removed from an ArrayList when necessary, which helps the user handle this same memory, and the method described can be defined as follows:
