On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of f0 * rn, where n is the distance (number of keys) from that key, and r is 2(1/12). Given an initial key frequency, output that frequency and the next 4 higher key frequencies.

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:

print('{:.2f} {:.2f} {:.2f} {:.2f} {:.2f}'.format(your_value1, your_value2, your_value3, your_value4, your_value5))

Ex: If the input is:

440
(which is the A key near the middle of a piano keyboard), the output is:

440.00 466.16 493.88 523.25 554.37

Answer 1

Answer:

In C:

#include <stdio.h>

#include <math.h>

int main(){

   float f0,r,temp;

   r = pow(2.0,1.0/12);

   printf("f0: ");    scanf("%f", &f0);

   temp = f0;

   for(int i = 0; i<=4;i++){

       f0 = f0 * pow(r,i);

       printf("%.2lf ", f0);

       f0 = temp;    }

   return 0;

}

Explanation:

This declares f0, r and temp as float

   float f0,r,temp;

This initializes r to 2^(1/12)

   r = pow(2.0,1.0/12);

This prompts the user for f0

   printf("f0: ");    scanf("%f", &f0);

This saves f0 in temp

   temp = f0;

This iterates the number of keys from 0 to 4

   for(int i = 0; i<=4;i++){

This calculates each key

       f0 = f0 * pow(r,i);

This prints the key

       printf("%.2lf ", f0);

This gets the initial value of f0

       f0 = temp;    }

   return 0;

Double clicking on the format pointer is the fastest way to copy the format from one cell to multiple other cells. Thus, the correct option is A.

What is Format pointer?

The format pointer holds a value which represents the memory address of an available data item in the file. If the data item from the file becomes unavailable. For example, because it is in a program which has been canceled then the pointer format is considered to hold a value which is incompatible with the format options.

Use the Format Painter to quickly apply the same formatting, such as the color, font style and size, or border style, to multiple pieces of text or graphics in the data item. With the help of format painter, a person can copy all of the formatting from one object and apply it to another object think of it as copying and pasting for formatting.

6) Read the article posted on The Verge entitled How to fight lies, tricks, and chaos online and summarize the four steps. Then answer the following: Are these four steps enough guidance to help us discover truth in this day and age? Justify your answer with supporting arguments.​

Answers

Answer:

A. Summarily, the four steps to accurately sharing information include;

1. consciously employing our senses to examine news deeply so as to accurately determine their source and purpose.

2. determining the origin of the story so as to know when and where it stems from.

3. examining the context of the material so as to find inconsistencies.

4. analyzing the evidence, arguments and information being presented in the story.

B. The four steps presented in the story are enough guidance to help us differentiate between accurate and false information on the net.

I agree with all of the points presented by the author of this article on analyzing information found online. Recently, I viewed a video on the net which was presented as a fact but a little digging revealed that the original video was a prank that had been edited, so as to remove important details. The first point raised by the speaker which is honing my senses to know that something is wrong with the information (it was too bad to be true), helped me to dig deeper. I found a link to the original video that revealed a completely different detail from what I had just seen.

Explanation:

For people who care that the information they share online are true, the points raised by the author of the article, "How to fight lies, tricks, and chaos online", can prove beneficial. The first step is applying one's senses to know when an information is too bad or good to be true. The next step is determining the origin of the story. When and where a story comes from is crucial to knowing if it is truly relevant.

Thirdly, reading in between lines might reveal that the story is deceitful and lacks truth or originality. Lastly weighing the evidence of the story will help the reader in knowing the usefulness of the story to him.

The child’s game, War, consists of two players each having a deck of cards. For each play, each person turns over the top card in his or her deck. The higher card wins that round of play and the winner takes both cards. The game continues until one person has all the cards and the other has none. Create a program that simulates a modified game of War.
The computer will play both hands, as PlayerOne and PlayerTwo, and, for each round will generate two random numbers and compare them.
If the first number is higher, PlayerOne’s score is increased by 1 and if the second number is higher, PlayerTwo’s score is increased by 1.
If there is a tie, no score is incremented.
When one "player" reaches a score of 10, that player should be deemed the winner and the game ends.
The range of numbers should be 1-13 to simulate the values of cards in the deck.

Your co-worker who went to UCLA tells you that DHCP is not enabled at your new job, so you should just use the same IP address that you have at home to connect to the internet. He told you it should work because your computer is communicating with a unique public IP address at home, so no other computer in the world would have it. When you try this, your computer does not have internet access. Give two reasons why?

Answers

Answer:

1. internet connection is not enabled on the computer.

2. The DHCP server in the company is not enabled as well.

Explanation:

For a user to access the internet, the computer must have a public IP address that is either assigned to it by a service provider or dynamically from the DHCP server in the computer. In the case of the former, the user just needs to enable the internet connection to obtain the unique IP address.

If the DHCP server or the internet connection is not enabled, the user would not have access to the internet.

Consider two different implementations, M1 and M2, of the same instruction set. There are three classes of instructions (A, B, and C) in the instruction set. M1 has a clock rate of 60MHz and M2 has a clock rate of 80MHz. The average number of cycles of each instruction class and their frequencies (for a typical program) are as follows:
Instruction Class M1-cycles M2-cycles/ Frequency
/instruction class instruction class
A 1 2 50%
B 2 3 20%
C 3 4 30%
a. Calculate the average CPI for each machine, M1 and M2.
b. Calculate the CPU execution time of M1 and M2.

Answers

Explanation:

A.)

we have two machines M1 and M2

cpi stands for clocks per instruction.

to get cpi for machine 1:

= we multiply frequencies with their corresponding M1 cycles and add everything up

50/100 x 1 = 0.5

20/100 x 2 = 0.4

30/100 x 3 = 0.9

CPI for M1 = 0.5 + 0.4 + 0.9 = 1.8

We find CPI for machine 2

we use the same formula we used for 1 above

50/100 x 2 = 1

20/100 x 3 = 0.6

30/100 x 4 = 1.2

CPI for m2 =  1 + 0.6 + 1.2 = 2.8

B.)

CPU execution time for m1 and m2

this is calculated by using the formula;

I * CPI/clock cycle time

execution time for A:

= I * 1.8/60X10⁶

= I x 30 nsec

execution time b:

I x 2.8/80x10⁶

= I x 35 nsec
