(a) The recursive definition of the sequence {an}, n = 1, 2, 3, ..., where an = 4n - 2 is:
a1 = 4(1) - 2 = 2
an = 4n - 2 for n > 1
The sequence starts with a1 = 2, and each subsequent term an is obtained by multiplying the previous term by 4 and subtracting 2.
(b) The recursive definition of the sequence {an}, n = 1, 2, 3, ..., where an = 1 + (-1)^n is:
a1 = 1 + (-1)^1 = 0
an = 1 + (-1)^n for n > 1
The sequence alternates between 0 and 2. Each term an is obtained by adding 1 to the previous term and multiplying it by -1.
(c) The recursive definition of the sequence {an}, n = 1, 2, 3, ..., where an = n(n + 1) is:
a1 = 1(1 + 1) = 2
an = n(n + 1) for n > 1
The sequence starts with a1 = 2, and each subsequent term an is obtained by multiplying n with (n + 1).
(d) The recursive definition of the sequence {an}, n = 1, 2, 3, ..., where an = n^2 is:
a1 = 1^2 = 1
an = n^2 for n > 1
The sequence starts with a1 = 1, and each subsequent term an is obtained by squaring the value of n.

Suppose we add a fixed amount of money into our bank account at the beginning of every year. Modify the program from this section to show how many years it takes for the balance to double, given the annual contributions and the interest. Also print the final balance.
import java.util.Scanner;
/**
This program computes the time required to double an investment
with an annual contribution.
*/
public class DoubleInvestment
{
public static void main(String[] args)
{
final double RATE = 5;
final double INITIAL_BALANCE = 10000;
final double TARGET = 2 * INITIAL_BALANCE;
Scanner in = new Scanner(System.in);
System.out.print("Annual contribution: ");
double contribution = in.nextDouble();
double balance = INITIAL_BALANCE;
int year = 0;
// TODO: Add annual contribution, but not in year 0
System.out.println("Year: " + year);
}
The balance is updated each year by adding the annual contribution and computing the interest.
Here is a modification of the given program to show the number of years it takes for the balance to double, along with the final balance, given the annual contributions and the interest rate:
import java.util.Scanner;
public class DoubleInvestment {
public static void main(String[] args) {
final double RATE = 5;
final double INITIAL_BALANCE = 10000;
final double TARGET = 2 * INITIAL_BALANCE;
Scanner in = new Scanner(System.in);
System.out.print("Annual contribution: ");
double contribution = in.nextDouble();
double balance = INITIAL_BALANCE;
int year = 0;
while (balance < TARGET) {
year++;
balance = balance * (1 + RATE / 100) + contribution;
}
System.out.println("Years to double: " + year);
System.out.println("Final balance: " + balance);
}
}
This program takes the annual contribution as input and calculates the number of years it takes for the balance to double, given the interest rate and initial balance. The balance is updated each year by adding the annual contribution and computing the interest. The loop continues until the balance reaches the target, at which point the number of years and the final balance are printed.

Based on the given options, none of the run-time complexity orders ranks between (log n) Logarithmic time and (n^2) Quadratic time. Therefpre, none of these is correct.
Among the given run-time complexity orders, (1) Constant time has the lowest complexity, followed by (log n) Logarithmic time, and then (n^2) Quadratic (or polynomial) time. There is no run-time complexity order that ranks between (log n) and (n^2).
Constant time (1) means that the algorithm's execution time remains the same, regardless of the input size. It is the most efficient complexity order.
Logarithmic time (log n) means that the algorithm's execution time increases logarithmically with the input size. It is more efficient than polynomial time but slower than constant time.
Quadratic time (n^2) means that the algorithm's execution time grows quadratically with the input size. It is less efficient than logarithmic and constant time.
Based on the given options, none of the run-time complexity orders ranks between (log n) Logarithmic time and (n^2) Quadratic time.

What happens when you copy an encrypted file from an EFS-enabled NTFS disk to a non-EFS disk or folder
When you copy an encrypted file from an EFS-enabled NTFS disk to a non-EFS disk or folder, the file loses its encryption.
What is EFS?EFS stands for Encrypted File System. This feature is included in Windows, which allows you to encrypt your data in NTFS disks. When you enable EFS on a file or folder, it's encrypted automatically with your account's public key.
As a result, only users who have access to your private key can decrypt the file or folder. EFS has several applications, including the protection of sensitive data from unauthorised access.
As a result, the file loses its encryption. When you move or copy an encrypted file to a non-EFS-enabled disk, it remains encrypted. It loses its encryption, though, when you copy it to a non-EFS-enabled folder or disk

Group of answer choices
Cybernetics
Chaos Theory
Scientific Management
Classical Organization Theory
Organizations that self-regulate via feedback loops can be described as applying principles of cybernetics.
Cybernetics is a field that deals with systems and control processes, specifically focusing on the study of feedback loops and self-regulation. Organizations that employ self-regulation through feedback loops can be seen as applying cybernetic principles to their operations. In this context, feedback loops refer to the process of gathering information about a system's performance, comparing it to desired outcomes, and making necessary adjustments to achieve those outcomes.
By using feedback loops, organizations can monitor their activities, evaluate their performance, and make continuous improvements. Feedback loops involve collecting data, analyzing it, and using the insights gained to adjust behaviors, processes, or strategies. This iterative process enables organizations to adapt to changes, optimize their performance, and achieve desired outcomes.
In summary, organizations that self-regulate via feedback loops can be understood as implementing principles from cybernetics. They utilize feedback mechanisms to monitor and adjust their operations, aiming to improve performance and achieve their goals.

2. Decrypt the encrypted three-letter word 15907 given the public key (n=91 687, e=7).
Decrypting the encrypted three-letter word 417 given the public key (n=45 173, e=5):Here, n= 45 173, e= 5. We know that c=417 as it is given in the question. So, to get the plaintext message we need to use the following formula: plaintext = c^ d mod n, where d is the private key.
To calculate d, we need to use the formula, d = e^-1 mod (p-1)(q-1), where p and q are the prime factors of n. We know that n=45 173=193 * 233. So, p=193, q=233. Using the formula, d = e^-1 mod (p-1)(q-1) = 5^-1 mod (192 * 232) = 92101 To calculate the plaintext, we use the formula, plaintext = c^d mod n = 417^92101 mod 45 173 = 703. So, the decrypted three-letter word 417 is mapped to "703" using the mapping A..Z to 1..26.
The decrypted three-letter word is GCH. Decrypting the encrypted three-letter word 15907 given the public key (n=91 687, e=7), Here, n= 91 687, e= 7.
