On a piano, each key has a frequency, and each subsequent key (black or white) is a known amount higher. Ex: The A key above middle C key has a frequency of 440 Hz. Each subsequent key (black or white) has a frequency of 440 * rn, where n is the number of keys from that A key, and r is 2(1/12). Given an initial frequency, output that frequency and the next 3 higher key frequencies. If the input is 440, the output is: 440 493.883 523.251 554.365.Note: Include one statement to compute r = 2(1/12) using the pow function, then use r in the formula fn = f0 * rn. (You'll have three statements using that formula, different only in the value for n).

NAT ________. allows a firm to have more internal IP addresses provides some security both allows a firm to have more internal IP addresses and provides some security neither allows a firm to have more internal IP addresses nor provides some security

Answers

Answer:

NAT provides some security but allows a firm to have more internal IP addresses

Explanation:

NAT ( network address translation) this is a process where a network system usually a firewall assigns a public IP address to an internal computer used in a private network. it limits the number of public IP address a company operating a private network for its computer can have and this is very economical also limits the exposure of the company's private network of computers. the computers can access information within the private network using multiple IP addresses but it is safer to access external information using one public IP address

I think it is sped up by around 0.6 GHz

Write a C++ program to find the number of pairs of integers in a given array of integers whose sum is equal to a specified number.

Answers

Answer:

int main()

{

int A1= {5,3,4,8,9,0,7};

int SArri1 = sizeof(A1);

printf("Original array: ");

for (int i=0; i < SArri1;i++)

printf("", A1[i] );

int i, sum = 20, n= 0;

printf("\nArray pairs whose sum equal to 20: ");

for (int i=0; i<SArri1; i++)

for (int j=i+1; j<SArri1; j++)

if (A1[i]+A1[j] == sum)

{

Printf(“\n”, array1[i])

Printf(“,”,array1[j]);

n++;

}

printf("\nNumber of pairs whose sum equal to 20: ",n)

return 0;

}

Explanation:

First of all, you should create the array of integers, and put random numbers. Then you have to save in a constant the size of the array (in this code is called SArr1) With a for you can print all the numbers that are on the array because then you will print all array pairs whose sum is equal to a specified numer. in this code we are going to use 20.

then with a condition (if) you are going to compare one of number of the array with all the others and check if its equal to 20. If yes, it going to print the numbers that answer to that condition and it's going to add +1 to the variable n (for this you will need to use two bucles for)

Then you can print the number of pairs whose sum is equal to 20 by printing n

Change the screen resolution so you can view more information on your screen. Use the resolution that enables you to fit the most information on the screen while still being able to read the display.Use the space below to indicate your screen resolution and to describe the steps you used to do this.

Answers

Answer:

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

Explanation:

My laptop's current screen resolution is (1366 by 768 recommended). When you change your screen resolution, your pc automatically suggests the recommended screen resolution that helps you to view more information on your screen and enable you to fit the most information on the screen while still being able to read the display.

To change the screen resolution, you need to go through from the following steps:

Right-click on empty space of desktop.
As you right-click, a list of options will open, select "display setting" among them
A new setting window will get open, at the left of the window, among given option, click on the first option i.e "display"
The content of the display setting gets open in the right area of the window. scroll down and find the "Scale and Layout"
under scale and layout, you can change your screen resolution while selecting the different screen resolution. However, it is good to select the recommended screen resolution based on your screen size.
