Answer:

C. reduce his variable expenses.

Explanation:

There are two types of expenses: Variable expenses and Fixed Expenses. Fixed Expenses are the expenses that are fixed for every month and its difficult to reduce these expenses such as house rent, fuel or travel expenses to go for work, utility bills. These are almost fixed for every month and it is difficult to reduce them. On the other hand, variable expense are the expense that vary for every month and can reduce easily. These expenses includes eating outside at restaurants, clothing, enjoying and arranging parties.

Rahul should reduce his variable expense to reduce his spending. This could be the easier way to reduce the expenses and save more. First option is not valid as he want to reduce his spending, this shows that he is satisfied with his current job but worried about extra expenses each month. This is the reason option C is the better choice for him to reduce expense.

How many different messages can be transmitted in n microseconds using three different signals if one signal requires 1 microsec
SIZIF [17.4K]

Answer:

a_{n} = 2/3 . 2^n + 1/3 . (-1)^n

Explanation:

Let a_{n} represents number of the message that can transmitted in <em>n </em>microsecond using three of different signals.

One signal requires one microsecond for transmittal: a_{n}-1

Another signal requires two microseconds for transmittal: a_{n}-2

The last signal requires two microseconds for transmittal: a_{n}-2

a_{n}= a_{n-1} + a_{n-2} + a_{n-2} = a_{n-1} + 2a_{n-2}, n ≥  2

In 0 microseconds. exactly 1 message can be sent: the empty message.

a_{0}= 1

In 1 microsecond. exactly 1 message can be sent (using the one signal of one  microseconds:

a_{0}= 1

2- Roots Characteristic equation

Let a_{n} = r^2, a_{n-1}=r and a_{n-2}= 1

r^2 = r+2

r^2 - r - 2 =0                 Subtract r+6 from each side

(r - 2)(n+1)=0                  Factorize

r - 2 = 0 or r +1 = 0       Zero product property

r = 2 or r = -1                 Solve each equation

Solution recurrence relation

The solution of the recurrence relation is then of the form a_{1} = a_{1 r^n 1} + a_{2 r^n 2} with r_{1} and r_{2} the roots of the characteristic equation.

a_{n} =a_{1} . 2^n + a_{2}.(-1)"

Initial conditions :

1 = a_{0} = a_{1} + a_{2}

1 = a_{1} = 2a_{1} - a_{2}

Add the previous two equations

2 = 3a_{1}

2/3 = a_{1}

Determine a_{2} from 1 = a_{1} + a_{2} and a_{1} = 2/3

a_{2} = 1 - a_{1} = 1 - 2 / 3 = 1/3

Thus, the solution of recursion relation is a_{n} = 2/3 . 2^n + 1/3 . (-1)^n

tatyana61 [14]

Answer:

The answer to this question with an explanation is given below in the explanation section

Why other options are not correct.

<em>By using the mini toolbar</em>

mini toolbar does not have the option that directly allows you to change the font

<em>By using paragraph option</em>

Using this option, you can only modify the paragraph setting, but not the font. Using this option, you can align the text of paragraph to center, left, right and justify, you can do numbering, add or remove the column, and make text direction.

<em>By using WordArt options</em>

Using this option, you can insert WordArt, these styles are predefined and don't allow you to change the font.

A prime number is a number that is divisible only by itself and 1. Write a program that asks a user for an integer value and the
Rashid [163]

Answer:

The Solution Code is written in Java.

  1. public class Main {
  2.    public static void main(String[] args) {
  3.        System.out.print("Please enter an integer: ");
  4.        Scanner input = new Scanner(System.in);
  5.        int number = input.nextInt();
  6.        System.out.print("Prime numbers less than or equal to " + number + " : ");
  7.        for(int i=2; i <= number; i++){
  8.            if(checkPrime(i)){
  9.                System.out.print(i + " ");
  10.            }
  11.        }
  12.    }
  13.    public static Boolean checkPrime(int num){
  14.        for(int i=2; i < num; i++)
  15.        {
  16.            if(num % i == 0){
  17.                return false;
  18.            }
  19.        }
  20.        return true;
  21.    }
  22. }

Explanation:

Firstly, we create a function to check if a number is prime (Line 18 - 27).

  • This function will take one input value which is an integer, num.
  • To check if the input num is a prime, we can use modulus operator, %, to confirm if the num is divisible by any number starting from 2 to num - 1 (Line 19 - 24).
  • If the num is divisible by any number expect 1 and itself, it should equal to zero and return false to indicate it is not a prime number.
  • If all the num (except 1 and itself) is not divisible, the function will return true (Line 25).

Next, in our main program part (Line 3 - 16)

  • Prompt the user to input a number (Line 5 - 7)
  • Using a for-loop, we can keep calling the checkPrime() function by passing a current number (starting from 2 to input number) as argument (Line 12). The checkPrime() function will run and return true it the current number is prime, return false if it is not prime.
  • If the checkPrime() function return true, it will print the current number before proceed to the iteration of the for-loop to repeat the same check prime procedure (Line 13)
  • At the end all the prime numbers less than or equal to the input number will be printed out in the terminal

earnstyle [38]

Answer:

View image below.

Explanation:

They're just asking you to create a num2bin function on Cpp.

If you search for "num2bin in C", you can find a bunch of answers for this if you think my solution is too confusing.

One way to do it is the way I did it in the picture.

Just copy that function and use it in your program. The rest you can do yourself.
