UseMath

Write a program called UseMath. It should contain a class called UseMath that contains the method main. The program should ask for a number from the user and then print the information shown in the examples below. Look at the examples below and write your program so it produces the same input/output.

Examples

(the input from the user is in bold face) % java UseMath enter a number: 0 the square root of 0.0 is: 0.0 rounded to the nearest integer: 0 the value of PI is: 3.141592653589793 the value of PI plus your number is: 3.141592653589793 rounded to the nearest integer: 3 the value of E plus your number is: 2.718281828459045 the absolute value of your number is: 0.0 % java UseMath enter a number: 1 the square root of 1.0 is: 1.0 rounded to the nearest integer: 1 the value of PI is: 3.141592653589793 the value of PI plus your number is: 4.141592653589793 rounded to the nearest integer: 4 the value of E plus your number is: 3.718281828459045 the absolute value of your number is: 1.0 % java UseMath enter a number: -1 the square root of -1.0 is: NaN rounded to the nearest integer: 0 the value of PI is: 3.141592653589793 the value of PI plus your number is: 2.141592653589793 rounded to the nearest integer: 2 the value of E plus your number is: 1.718281828459045 the absolute value of your number is: 1.0 % java UseMath enter a number: .5 the square root of 0.5 is: 0.7071067811865476 rounded to the nearest integer: 1 the value of PI is: 3.141592653589793 the value of PI plus your number is: 3.641592653589793 rounded to the nearest integer: 4 the value of E plus your number is: 3.218281828459045 the absolute value of your number is: 0.5 % java UseMath enter a number: .1 the square root of 0.1 is: 0.31622776601683794 rounded to the nearest integer: 0 the value of PI is: 3.141592653589793 the value of PI plus your number is: 3.241592653589793 rounded to the nearest integer: 3 the value of E plus your number is: 2.818281828459045 the absolute value of your number is: 0.1 % java UseMath enter a number: 10 the square root of 10.0 is: 3.1622776601683795 rounded to the nearest integer: 3 the value of PI is: 3.141592653589793 the value of PI plus your number is: 13.141592653589793 rounded to the nearest integer: 13 the value of E plus your number is: 12.718281828459045 the absolute value of your number is: 10.0 %

I am trying to figure out how to add a couple methods to a program I am working on.

I need to be able to:

1. Remove elements from a binary tree

2. Print them in breadth first order

Any help would appreciated.

The five key activities in an object-oriented design process are:

a. Define the context and modes of use of the system;
b. Design the system architecture;
c. Identify the principal system objects;
d. Develop design models;
e. Specify object interfaces.

Please give me an explanation and example in detail for the five activities.

Q.1 A social psychologist is interested in whether the amount of couple photos (photos featuring the couple together) people post on social media would vary across relationship stages. He administered a questionnaire to a group of couples (one questionnaire for each couple) at the anniversaries of their first year, second year, third year, and fourth year of dating. The questionnaire asked about the total amount of couple photos they posted in social media during the past year. Below are the data, with a higher number denoting more couple photos posted:

a. What are the independent variable and dependent variable of this study?

b. Write down the omnibus null hypothesis and the alternative hypothesis for the overall effect of the independent variable.

c. Conduct a proper statistical test by hand calculation to test the omnibus hypothesis with 5% as the level of significance (α). (For this exercise, the data assumptions of your chosen statistical test can be taken as reasonably met.) Show your calculation formulae and steps. In case you decide to conduct an ANOVA, you are not required to conduct any post-hoc comparisons. Decide whether to reject the null hypothesis or not and state the basis of your decision.

d. Calculate the effect size in terms of eta-squared and omega-squared.

At the beach, some waves with wavelength of 100 m propagate towards the shore at a speed of 12.5 m/s. (c) Does the engine sound higher- or lower-pitched to someone standing on the shore, compared with the experience of people on the boat?

(a) Calculate the frequency that boat anchored near shore bobs up and down as the waves roll in.

(b) At what frequency the boat would bob up and down with if it were headed away from the shore at a speed of 4.8 m/s?

(c) At what frequency the boat would bob up and down with if it were headed toward the shore at a speed of 4.8 m/s?

The language is C++

Below are a list of sequences of numbers. Your job is to program each sequence with any loop of your preference (while, for, do/while). I want the code to output the sequence provided and the next number in the sequence (you can output more but there is 1 sequence that may only have 1 number after).. Please order and notate each sequence in your output –. The output should also be horizontal like that shown below (if you output it vertically it will be -10pts). Each sequence should be programed with only 1 loop and optionally 1 selection statement. Hint: a selection statement may be used for the last 3 problems.

        The United States Federal Income tax for taxes due July 15, 2020
    is available at this link: https://www.bankrate.com/finance/taxes/tax-brackets.aspx
        The four tax filing categories are: 0 - single filer, 2 - head of household, 
        3 - married filing jointly or qualifying widow, and 4 - married filing
        seperately. 
        
        Write a Java program that prompts the user to enter the name, filing status, and
        annual income. The program returns the federal income tax due. (10 Points)
        
        A sample run should look like:
        Enter your name: Jane Doe
        Enter your 2019 federal income: 48,000
        Enter your filing status: single
        
        Jane Doe, the federal income tax for an annual salary of
        48,000 for a single filer is $4,800.
        
        
        Draw a UML diagram for the class. You may use Astah tool. (5 points).
        
        
        Submit both the java code and UML diagram.

This is a beginner C++ class

Your program will be creating 10 library books. Each library book will have a title, author and publishing year. Each library book will be stored as a structure and your program will have an array of library books (an array of structures).

After creating the struct, the next task is to create a new separate array for book genres.

You will create this corresponding array of book genres: Mystery, Romance, Fantasy, Technology, Children, etc. If the first element of the structure is storing information about a book titled : "More about Paddington", then the corresponding first element of array book genre would indicate 'Children'.

You should only use structure and array. You are not allowed to use vectors.

The user of your program should be able to select what they want to do from a menu of the following things and your program needs to do what the menu selection indicates:

* Print the entire list of library books (including the title, author, publishing year and book genre)

* Display a count of how many books exist per genre

* Find and display all books where the publishing year is greater than the year user put in

* Print the titles of the books where the Genre may be indicated by a 'C' for Children, & 'M' for Mystery
