Write a method that takes two rectangles and returns the (positive) difference between their areas.
This method must be named areaDiff() and have 2 Rectangle parameters. This method must return a double.
For example suppose two Rectangle objects were initialized as shown:
Rectangle rect1 = new Rectangle(2.0, 8.0);
Rectangle rect2 = new Rectangle(6.0, 3.0);
The method call areaDiff(rect1, rect2) should then return the value 2.0.
Answers
The program to define a method that computes the positive difference between the areas of two rectangles is found in the attached image.
The program defines a class Rectangle with a constructor, and a static method areaDiff. The static method areaDiff takes two rectangles (rect1 and rect2) and returns the positive difference between their areas.
The formula used by areaDiff is:
[tex]|(rect1.width \times rect1.height)-(rect2.width \times rect2.height)|[/tex]
where
[tex]rect1,rect2=\text{the two rectangles}\\(rect.width\times rect.height)\text{ calculates the area of a rectangle object}\\|x|=\text{the absolute value function}[/tex]

Answer:
Explanation:
Most word processors use Save As which not only allows you to save with a different name, but the root can be changed as well. I use LibreOffice write. Its Save As Command allows you to change the name from say J1 to Jerome and also to save the document in many of the word formats. That last ability is really important because some people only have Microsoft products. On my old computer, I have Microsoft Word 2000.

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

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.

which kind of blocks is used to hold values
Answers
Answer:
Variable block.
Explanation:
In Computer programming, a variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited.
Basically, variable stores information which is passed from the location of the method call directly to the method that is called by the program.
For example, they can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function. Therefore, when you create variables in a function, you can can set the values for their parameters.
For instance, to pass a class to a family of classes use the code;
\\parameter Name as Type (Keywords) = value;
\\procedure XorSwap (var a,b :integer) = "myvalue";
Hence, variable block is used to hold values. Also, it can be used to hold strings in variables, which may be displayed through the computer monitor.
