2.32 LAB: Musical note frequencies 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 by executing cout << fixed << setprecision(2); once before all other cout statements. Ex: If the input is: 440.0 (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

[tex]\text{This is a python code:}[/tex]
[tex]\text{import math}[/tex]
[tex]your {\_} {value 1 }= float(inpu \ t ())[/tex]
[tex]your{\_}value 2 = your{\_}value1*math.exp(1 * math.log(2) / 12)[/tex]
[tex]your{\_}value 3 = your{\_}value1*math.exp(2 * math.log(2) / 12)[/tex]
[tex]your{\_}value 4 = your{\_}value1*math.exp(3 * math.log(2) / 12)[/tex]
[tex]your{\_}value 5 = your{\_}value1*math.exp(4 * math.log(2) / 12)[/tex]
[tex]print('\{:.2f\} \{:.2f\} \{:.2f\} \{:.2f\} \{:.2f\}'.format(your\_value1, \ your\_value2, \ your\_value3,[/tex][tex]\ your\_value4, \ \ your\_value5))[/tex]

[tex]\mathbf{440.00 \ 466.16 \ 493.88 \ 523.25 \ 554.37}[/tex]
The code for musical note frequencies On a piano, a key has a frequency, say f0 is in the explanation part below.
Here is a C++ program to the stated problem:
#include <iostream>
#include <iomanip>
#include <cmath>
int main() {
double frequency;
std::cout << "Enter the initial key frequency: ";
std::cin >> frequency;
std::cout << std::fixed << std::setprecision(2); // Set output precision to 2 decimal places
std::cout << frequency << " ";
for (int i = 1; i <= 4; ++i) {
frequency *= std::pow(2, 1.0 / 12); // Calculate the next frequency
std::cout << frequency << " ";
}
return 0;
}
Thus, in this program, we use the user's original key frequency as input. The starting frequency and the following four higher key frequencies are then calculated and produced using a loop.

You learned that you can use the tags to insert a link to another webpage. One problem that webpage developers face is that, after a time, links may no longer work. Can you think of ways that you can avoid broken links?
Answer:Image Control
We can use the height and width properties to control the size of our image. Let’s say we only want the recipe image to take up approximately one-third of the page. Do you remember from math class what percentage one-third is? Type in the following CSS rule, and watch your picture change size before your very eyes!
img {
height:33%;
width:33%;
}
That wasn’t too difficult, right? Let’s make the image stand out a bit more by adding a border. Inside the img rule, add the following declarations:
border-style:dashed;
border-width: 5px;
Your picture should now have a dashed border around it that is five pixels in width. Play around with the different border styles that are available. You should see a drop-down box of choices, including dotted, dashed, double, groove, inset, and outset. You can also adjust the width of your border. Using your informative guessing skills, can you predict what property you might use to change the color of the border? Try it and see if you’re right!
