return (w);
}
int main (void)
{
int a = 2;
printf ("%d", toronto (a));
return (0); }

a. 0
b. 1
c. 2
d. -1
e. none of these

Answers

Answer:

The output is 1

Explanation:

Analysing the flow of program (We start from the main method)

The main begins here

int main (void) {

This line declares a as integer and also initializes it to 2

int a = 2;

This line passes 2 to the function names toronto and also prints the result of the function

printf ("%d", toronto (a));

return (0); }

The toronto function begins here.

Note that the function receives 2 as its argument and this is saved in variable x

int toronto (int x) {

This declares w as integer

int w;

If x is 0, w equals 1

if (x == 0) w = 1;

If otherwise

else

This reduces x by 1 and performs a recursion

w = toronto (x-1);

return (w);

}

Because of the structure of the if condition in the toronto function, the function will be repeated until x is 0.

And when x = 0; w = 1

This returns w (i.e. 1) back to the main function where 1 is printed as the output

return (w);

we need to send 254 kbps over a noiseless channel with a bandwidth of 15 khz. how many signal levels do we need

Answers

Answer:

The level of the signal is 353.85

Explanation:

Data rate determines the speed of the data transmission.

The data rate depends on the following factors

The available bandwidthnumbers of signal levelsthe quality of the channel ( Means the level of noise )

The data is transmitted either from a noiseless channel or a noisy channel.

The given quality of the channel in the question is noiseless.

Use the following formula to calculate the signal levels

Bit rate = 2 x bandwidth x [tex]Log_{2}[/tex] ( signal level )

where

Transmitted Data = 254 kbps = 254,000 bps

Bandwidth = 15 khz = 15,000 hz

Placing values in the formula

254,000 = 2 x 15,000 x [tex]Log_{2}[/tex] ( L )

254,000 = 30,000 x [tex]Log_{2}[/tex] ( L )

254,000 / 30,000 = [tex]Log_{2}[/tex] ( L )

8.467 = [tex]Log_{2}[/tex] ( L )

L = [tex]2^{8.467}[/tex]

L = 353.85 levels

B. It ensures that payments to credit card accounts are categorized correctly

D. It uses language that non-accountants can understand

Explanation:

Pay down credit card workflow is a new feature that makes entering records in QuickBooks easier for users. The two prime benefits of this workflow are;

1. It ensures that payments to credit card accounts are well categorized well. Without this feature, users most times find it difficult to enter records correctly or they tend to duplicate entries. This new feature obtains vital information that helps the software to correctly credit the accounts.

2. It uses language that non-accountants can understand. This simplifies the process and makes it easier for the user to enter the right data that would help the software to correctly credit the accounts.

When ordering a quadruple-shot latte, which contains four shots of espresso, you can also use the word quadruple to signify “four times as many.” The suffix quadric-, which means “four,” is the source of the Latin root quadruple, which means “create fourfold.”

Three address codes are also referred to as quadruples. Using pointers to entries in a symbol table as the operands and an enumerated type to represent the operations, quadruples can be accomplished.

Fix the infinite loop so that it counts from 3 down to 1.public class Loop1{public static void main(String[] args){int x = 3;while (x > 0){System.out.println(x);}}}

Answers

Answer:

Include x-- right after the print statement

Explanation:

Given:

The above lines of code

Required

Edit to countdown from 3 to 1

The above code (as it is) prints 3 in infinite times. To make it countdown to 1, we simply include a decrement operation.

Initially, the value of x is 3: int x = 3;

And the condition is that the loop is to be repeated as long as x > 0

All we need to do is to include x-- right after the print statement.

This  operation will reduce the value of x on every iteration as long as the condition is true.

Hence, the complete code is:

public class Loop1{

   public static void main(String[] args){

       int x = 3;

       while (x > 0){

           System.out.println(x);

          x--;

       }}}

Additional GB can be purchased at the following rates: $12 for an additional 1 GB, $28 for an additional 3 GB, and $44 for a capacity of 10 GB. What is the cost for a user who is expecting to use 9 GB

Answers

Answer:

For 9GB of data the user would pay $82 monthly!

Explanation:

To start off, our end goal is 9GB. We have the equation 9 = ? We can add up to our solutions with 1GB, 3GB, and 10GB. We can immediately rule out 10GB, since 9GB ≠ 10GB. To cost the least amount of money we can add up             3GB and 1GB = 4GB + 5GB = 9GB!

So, our equation is 3GB + 1GB + 5GB = 9GB, now lets figure out the cost!

                                $28 + $12 + $42 = $82

For 9GB of data the user would pay $82 monthly!
