Using article: social distancing to test if technology can solve the loneliness epidemic By NICOLE VAN GRONINGEN

1. This is a two-part question. Be sure to answer both parts! You can answer the two parts together as long as you address both parts. Your full answer should be 2-4 sentences.
a. Who do you think is the intended audience (reader) of this article? That is, who is the author, Nicole Groningen, writing the article for? Explain.
b. What is the author’s purpose in writing? That is, what does she hope the readers will learn, do, or think about based on reading this article? Explain.

2. Considering the article as a whole, is the author making an argument? Is she explaining something? Is she suggesting something? What verb (argue, explain, suggest, or another verb) best describes what she is doing, and how can you tell? There’s no single right answer to this; explaining your choice is more important than which verb you pick. Explain your answer in 1-2 sentences.
3. According to paragraphs 13 and 14, how might technology companies benefit from this period of social distancing during COVID-19? Explain your answer in 1-2 sentences.

The schema for the Academics database is as follows. Understanding this schema is necessary to answer the questions in Part B.

DEPARTMENT(deptnum, descrip, instname, deptname, state, postcode) 
ACADEMIC(acnum, deptnum*, famname, givename, initials, title) 
PAPER(panum, title) 
AUTHOR(panum*, acnum*) 
FIELD(fieldnum, id, title) 
INTEREST(fieldnum*, acnum*, descrip) 

The semantics of most attributes are self-explanatory. For each relation, the primary key is underlined and any foreign keys are denoted by an asterisk (*). Some additional information for relations is given below:

• DEPARTMENT: Each academic department (deptnum) belongs to an institution (instname).  
• ACADEMIC: Each academic (acnum) belongs to one department (deptnum).  

• AUTHOR: A paper (panum) may be written by more than one academic (acnum).  
• FIELD: The relation describes research areas, where id is a classification code like B.1.1.  
• INTEREST: The relation describes that an academic may have research interests in several fields (fieldnum), and provide description (descrip) of his/her research.

Question1 SQL

calculate the number of academics that have more than 10 papers?

Question 2 SQL

find the departments where at most 10 academics have more than 2 research fields, and display in alphabetical order the names of institutions and names of departments?

A publisher in a competitive market faces the following cost schedule for publishing a novel by one of its authors: the author is paid a $3,000,000 up-front signing bonus to write the book (it is not refundable). The going market price for a hardcover book is $32 per copy. Where Q is the number of books printed and AVC is the average variable cost of producing books at a given Q.

1. Compute total revenue, total cost and profit at each quantity.
2. Compute marginal revenue. How does marginal revenue compare to price? Explain.
3. Compute marginal cost.
4. Is there a quantity where marginal revenue and marginal cost cross? What does this signify? What is the quantity?
5. What quantity would a competitive profit maximizing publisher choose?
6. If the author were paid $4 million instead of $3 million to write the book, how would this affect the publisher’s decision on what quantity to sell and its profits?

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

Circle Class (This is in JAVA)

/**
 * Defines a basic shape with just area
 *
 * @author Jo Belle
 * @version 0.2 (10/05/2020)
 */
public class Shape{
    private double area;

    public Shape(){ area = 0.0; }
    public Shape( double a ){ this.area = a; }
    public void setArea( double a ){ area = a; }
    public double getArea(){ return area; }
    public String toString(){
        return "Shape:\n\tarea: " + area;
    }
}

/**
 * Create a simple Circle object
 *
 * @author Jo Belle
 * @version 0.2 (10/12/2020)
 */
public class ShapeDriver{
    public static void main( String[] args ){
        Circle cir = new Circle( );
        cir.setRadius( 5.0 );
        System.out.println( cir.toString() );
    }
}

Given the code above, write a Circle class (and save it in a file named Circle.java) that inherits from the Shape class. Include in your Circle class, a single private field double radius. Also include a method void setRadius(double r) (which also sets area) and a method double getRadius() (which also returns the current radius). Change the accessibility modifier for area in the Shape class to be more appropriate for a base class. Make sure that ShapeDriver's main() method executes and produces the following output:

Shape:
        area: 78.53981633974483
        radius: 5.0

Submit both your Circle.java and your Shape.java files.
