Answer:
I believe it is just a task. Since there exists(on windows) the Task Manager application, where you can stop any running task, I think that they are called tasks
Explanation:
In most operating systems, a running application is typically referred to as a process. A process is an instance of a program that is being executed by the operating system. It represents the execution of a set of instructions and includes the program code, data, and resources required for its execution.
Each process has its own virtual address space, which contains the program's code, variables, and dynamically allocated memory. The operating system manages and schedules these processes, allocating system resources such as CPU time, memory, and input/output devices to ensure their proper execution.
The operating system provides various mechanisms to manage processes, such as process creation, termination, scheduling, and inter-process communication.

Answer:
Following are the code to this question:
x = int(input())#defining a variable x for user input value
if(x>=20 and x<=98):#defining an if block that checks value is in between 20 to 98
while(not(x%10==x//10)):#defining while loop that seprate numbers and checks it is not equal

Explanation:
In the above python program code, a variable x is declared, which is used to input the value from the user end. In the next step, a conditional statement is used in if block, it checks the input value is lie in 20 to 98, and to check its uses and logic date, if it is false it will goto else section in this, it will print a message. If the given value is true, inside if block a while loop is declared, that separately divide the value and check it is identical or not, if it is not identical it will print the value and checks its less value similarly.The program that takes in an integer in the range 20-98 as input. The output is a countdown starting from the integer, and stopping when both output digits are identical is as follows:
x = int(input("your number should be between 20 to 98: "))
while 20 <= x <= 98:
print(x, end='\n')
if x % 11 == 0:
break
x -= 1
else:
print("your number must be between 20 to 98")
Code explanation:The code is written in python
The first line of code, we store the users input in the variable x.Then while 20 is less than or equal to or less than and equals to the users input, we have to print the x value .If the users input divides 11 without remainder(the digit are the same) then we break the loop. The loop continue as we subtract one from the users valueThe else statement wants us to tell the user to input numbers between 20 to 98learn more on python code here: https://brainly.com/question/26104476
what are functions? Give three (3) examples of mathematical functions
Answer:
A function is mathematical relation where the domain (x/input) has only 1 range (y/output) that matches to it.
For example, if the domain is 7, it can only match to one range. 7 cannot match to (for example) 2 and 3. However, multiple domains can have the same range. For example, domains 7 and 8 can both output to range 2.
That is the main difference from an equation.
Examples:
f(x) = x^2
f(x) = |x|
f(x) = \(\sqrt{x}\)

A function in programming is a piece of program code that carries a set of instructions or commands that solve a specific task.
