Hello, you haven't provided the programing language in which you need the code, I'll explain how to do it using Python, and you can follow the same logic to make a program in the programing language that you need.
Answer:
1. # -*- coding: utf-8 -*-
2. #Python
3. class Calculator:
4. def add(self):
5. print(a + b)
6. def sub(self):
7. print(a - b)
8. def mul(self):
9. print(a * b)
10. def div(self):
11. print(a / b)
12.
13. obj = Calculator()
14. choice = 1
15. while choice != 0:
16. a = int(input("\nEnter first number: "))
17. b = int(input("Enter first number: "))
18.
19. print("\n0. EXIT")
20. print("1. DIVISION")
21. print("2. ADDITION")
22. print("3. SUBTRACTION")
23. print("4. MULTIPLICATION")
24.
25. choice = int(input("\nEnter your choice: "))
26. if choice == 1:
27. obj.div()
28. elif choice == 2:
29. obj.add()
30. elif choice == 3:
31. obj.sub()
32. elif choice == 4:
33. obj.mul()
34. else:
35. break
Explanation:
- From lines 1 to 12 we define the object with four methods, addition, subtraction, multiplication, and division. Each method contains the operation between two variables inside a print function
- On line 13 we instantiate our class
- On line 14 we declare the variable choice that is going to store the operation that the user wants to perform
- On line 15 we declare a while loop, this is going to keep running the program until the user wants to exit
- From line 16 to 18 we ask the user to enter two numbers
- From line 19 to 24 we print the possible operation, assigning a number for each operation, this indicates to the user what number to press for what operation
- On line 25 we ask the user for the operation
- From lines 26 to 35 we check the user input an accordingly we call the corresponding method to performs the operation
Answer:
Differentiation
Explanation:
Differentiation is a business strategy used by organizations for gaining a competitive edge over competitors in the market.
During this approach, the organizations/business introduces a special strategy which goal is to differentiate their product or service in a positive way, from other products that are alike.
In this scenario the organization(CompX Inc) is offering a superior customer support.
B. Select the range of data. You have to highlight it first so it knows what you are going to convert into a table.
Answer:
The answer of the the following question are 0(n^2)
The total number of multiplication is 2
And the total number of addition is 1
Explanation:
Let the size of the input is the degree of the polynomial = "n"
Than the number of the multiplications depends on "n"
Let the number of multiplication = M(n)
Let the number of addition = A(n)
1): Solution-
M(n) = n∑_{i=0} i∑_{j=1} 2
= 2 n∑_{i=0} i∑_{j=1}
= 2 n∑_{i=0} i-1+1
= 2 n∑_{i=0} i
= 2 * n*(n+1)/2 = n*(n+1)
= n^2 + n ∈ 0(n^2)
2): Solution for addition-
A(n) = n∑_{i=0} i∑_{j=1} 1
= by solving this from the same way it leads to
= n^2 + n and n^2 + n ∈ 0(n^2)
