Answer:
One.
Explanation:
When two or more domains (trees) not sharing a contiguous namespace are joined together, a forest would be formed.
This ultimately implies that, a forest is formed by joining two or more independent domains having non-contiguous namespaces are joined together.
For instance, joining brainly1.com and brainly2.com would result in a forest i.e a single Active Directory environment.
In this scenario, Mary is working on joining of a new domain tree to an existing forest. Before starting the process, she should have at least one domains present. This single domain is typically known as the root domain.
Hence, joining a new domain tree to an existing forest requires that a user must have at least one domains present.
In this exercise, you will get some practice with the __add__ method by implementing it for a class called ContactBook. This class represents a collection of names and phone numbers. ContactBook stores its information as a dictionary, where the key is a name and the value is a phone number or group of phone numbers. The keys and values in this dictionary are stored as strings. When printed, a ContactBook might look like this:
Answer:
class ContactBook():
def __init__(self):
self.contacts ={}
def __repr__(self):
return str(self.contacts)
def add_contact(self,name,number):
self.contacts[name] = number
def __add__(self, other):
new_contact = ContactBook()
other_contact = other.contacts.keys()
for name,num in self.contacts.items():
if name in other_contact:
new_contact.add_contact(name,num or other_contact[name])
else:
new_contact.add_contact(name,num)
for name,num in other.contacts.items():
if name not in self.contacts:
new_contact.add_contact(name, num)
return new_contact-
cb1 = ContactBook()
cb2 = ContactBook()
cb1.add_contact('Jonathan','444-555-6666')
cb1.add_contact('Puneet','333-555-7777')
cb2.add_contact('Jonathan','222-555-8888')
cb2.add_contact('Lisa','111-555-9999')
print(cb1)
print(cb2)
cb3 = cb1+cb2
print(cb3)
Explanation:
The ContactBook class holds the contact details of an instance of the class. The class has three magic methods the '__repr__', '__init__', and the '__add__' which is the focus of the code. The add magic method in the class adds the contact book (dictionary) of two added object instance and returns a new class with the contact details of both operand instances which is denoted as self and other.
Explain briefly what would happen if marketing research is not conducted before a product is developed and produced for sale.
Answer:
Neglecting to do market research can result in indecision and inaction, fear of risk or the truth, and/or too many options, which can lead to paralysis. When launching a new product, effective market research will help you narrow down your true market potential and your most likely customers.

-(-13) P binary using signed. 2's complement representation
Perform the arithmetic operations (+42) + (-13) and (-42)
negative .
Consider the balloon
Answer:
00011101
00011101
Explanation:
Given the following arithmetic operations
a) (+42) + (-13)
b) (-42) - (-13)
From (a):
We need to convert +42 into binary, so we get = 00101010
Now for +13, when it is converted into binary, we get = 00001101
But, here, the 13 is negative. So, here is what we will do, we will have to take the two compliment of the binary. After doing that, we get = 111110011
∴
+ 42 → 00101010
- 13 → 1 1 1 10011
+29 000 11101
Thus, the arithmetic operation after we use 2's complement is 00011101
b)
Here both 42 and 13 are negative. Using two complement representation
-42 is first converted to binary as 00101010, Then → 11010101 + 1 = 11010110
-13 is converted to binary as 00001101 → 11110010 = 11110011
In between, a negative sign exists, so we take another 2's complement.
i.e.
11110011 → 00001100 + 1 = 00001101
- 42 → 1 1 01 0110
+13 → 00001 101
-29 1 1 1 00011
since there is no carry, we take two's complements for the result as:
1 1 1 00011 →00011100 + 1 = 00011101
SQL allows the use of special operators in conjunction with the WHERE clause. A special operator used to check whether an attribute value matches a value contained within a subset of listed values is ____. Question 20 options: BETWEEN IS NULL LIKE IN
Answer:
LIKE.
Explanation:
A structured query language (SQL) can be defined as a domain-specific language designed and developed for managing the various data saved in a relational or structured database.
In Computer programming, any word restricted for use, only in object names because they belong to the SQL programming language are called reserved word.
Hence, these reserved words can only be used as the name of an object but not as an identifier e.g the name of a function, label or variable.
Some examples of reserved words in structured query language (SQL) are UPDATE, GROUP, CURRENT_USER, CURRENT_DATE, CREATE, DELETE etc.
Hence, SQL allows the use of special operators in conjunction with the WHERE clause. A special operator used to check whether an attribute value matches a value contained within a subset of listed values is LIKE.
A customer is looking for a storage archival solution for 1,000 TB of data. The customer requires that the solution be durable and data be available within a few hours of requesting it, but not exceeding a day. The solution should be as cost-effective as possible. To meet security compliance policies, data must be encrypted at rest. The customer expects they will need to fetch the data two times in a year. Which storage solution should a Solutions Architect recommend to meet these requirements
Incomplete question. The options;
A. Copy data to Amazon S3 buckets by using server-side encryption. Move data to Amazon S3 to reduce redundancy storage (RRS).
B. Copy data to encrypted Amazon EBS volumes, then store data into Amazon S3.
C. Copy each object into a separate Amazon Glacier vault and let Amazon Glacier take care of encryption.
D. Copy data to Amazon S3 with server-side encryption. Configure lifecycle management policies to move data to Amazon Glacier after 0 days.
Answer:
D. Copy data to Amazon S3 with server-side encryption. Configure lifecycle management policies to move data to Amazon Glacier after 0 days.
Explanation:
Note, the Amazon S3 (Amazon Simple Storage Service) is a cloud storage service that is both durable, cost-effective, and secure. Since the customer wants a storage space of up to 1,000 TB (terra bytes), this makes the Amazon S3 solution the most recommended solution.
The process begins by copying the data to Amazon S3 with server-side encryption. Next, set-up the configuration of lifecycle management policies to move data to Amazon Glacier after 0 days.
Write a recursive function to determine if a number is prime.
Answer:
Follows are the code to find the prime number:
import java.util.*;//import package for user input
public class Main//defining a class
{
public static boolean Prime(int x, int j)//defining a method isPrime
{
if (x<= 2) //use if block to check x less than equal to 2
return (x== 2) ? true : false; //use bitwise operator to return value
if (x%j == 0) //use if to check x%j equal to 0
return false;//return false value
if (j*j > x)//defining if that check i square value greater than n
return true; //return true value
return Prime(x, j+1); //callling recursive method
}
public static void main(String[] as)//main method
{
int n; //defining integer variable
Scanner oxc=new Scanner(System.in);//creating Scanner class object
n=oxc.nextInt();//input value
if (Prime(n, 2)) //use if block to call isPrime method
System.out.println("Yes"); //print value
else //else block
System.out.println("No"); //print value
}
}
Output:
5
Yes
Explanation:
In this code, a static boolean method "Prime" is declared, that accepts two integer variables in its parameter and defines the if block that checks the prime number condition by the recursive method and returns a value true or false. Inside, the main method an integer variable is declared that uses the Scanner class object for input value and passes into the method and prints its value.

I made up my own names for the sake of testing my code. I wrote my code in python 3.8. I hope this helps.
A loop that will output only the names that come before "Thor" in the alphabet from the names list is written below:
What is a loop?A loop is a set of instructions in computer programming languages that repeatedly repeats itself until a given condition is met.
The time it takes to determine the number of times the loop iterates before the loop executes is the difference between the decorative and extensive program loops.
If a loop's block of code is to be repeated until the provided condition turns false, and this condition is tested before the block is run, the loop is said to be a pretest.
names = ["Kevin", "Joe", "Thor", "Adam", "Zoe"]
names.sort()
for x in names:
if x == "Thor":
break
else:
print(x)
Therefore, the loop is written or coded above.

While setting up a computer on the network, you use 'ipconfig' and see that the IP address is currently 10.24.16.160, with subnet mask 255.255.255.192. Where did the IP address likely come from?
Answer:
Explanation:
The IP address either came from your router or your Internet Service Provider (ISP). Sometimes ISP's automatically assign every device under their network an IP address, while other times they allow each individual's home network router to determine the IP of every connected device. This router can either assign an automatic IP address to each device from a range of addresses or the IP address can be assigned manually to each device as static.
Consider the following method, which is intended to return an array of integers that contains the elements of the parameter arr arranged in reverse order. For example array containing (-5, 3, 2, 7) then a new array (-5, 3, 2, 7) contains should be returned and the parameter are should be left unchanged .
public static int[] reverse(int) arr)
Intl new new intarr.length);
for (int k = 0; K arr.length: )
* Bissing statement / return newer;
Write down the statements that can be used to replace / Missing statement so that the method works as intended?
Code:
public static int[] reverse(int [] arr){
Int [] newArr = new int[arr.length];
for (int k = 0; k<arr.length;k++){
/*Missing statement */
}
return newArr;
Answer:
Replace the comment with:
newArr[k] = arr[arr.length-k];
Explanation:
Required
Complete the code
In the given code:
The first line of the given code defines the method
public static int[] reverse(int [] arr){
The next line declares array newArr withe same length as array arr
Int [] newArr = new int[arr.length];
The next line iterates through the elements of array arr
for (int k = 0; k<arr.length;k++){
The /* Missing statement */ is then replaced with:
newArr[k] = arr[arr.length-k];
The above statement gets the elements of array arr in reversed order.
This is so because, as the iteration iterates through array arr in ascending order, arr.length-k gets the element in reversed order
