CHALLENGE ACTIVITY 2.9.1: Coordinate geometry. Determine the distance between points (x1, y1) and point (x2, y2), and assign the

Burka [1]

Answer:

import java.util.Scanner;

public class TestClass {

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

System.out.println("Enter value for x1, x2, y1, y2");

double x1 = input.nextDouble();

double x2 = input.nextDouble();

double y1 = input.nextDouble();

double y2 = input.nextDouble();

double xVal = Math.pow((x2-x1),2);

double yVal = Math.pow((y2-y1),2);

double distance = Math.sqrt(xVal+yVal);

System.out.println(distance);

}

}

Explanation:

The code is written in Java Programming Language.

This code simply implements the formula for the distance between two points given as

distance = $\sqrt{(x2-x1)^{2}+(y2-y1)^{2} )}$

The scanner class is used to prompt and receive all the variables that are declared.

Note that we used two special Java methods (Math.pow and Math.sqrt)

Write a SQL query to find the population of the planet named 'Caprica' -- 10 points Find the first name, last name, and age of p

Artemon [7]

The question is incomplete! Complete question along with answer and step by step explanation is provided below.

Please find the attached question.

Answer:

a) SQL Query:

SELECT population

FROM bsg_planets

WHERE name='Caprica';

b) SQL Query:

SELECT fname, lname, age

FROM bsg_people

WHERE lname!='Adama';

c) SQL Query:

SELECT name, population

FROM bsg_planets

WHERE population > 2600000000

d) SQL Query:

SELECT fname, lname, age

FROM bsg_people

WHERE age IS NULL;

Explanation:

a) Write a SQL query to find the population of the planet named 'Caprica'

Syntax:

SELECT Column

FROM TableName

WHERE Condition;

For the given case,

Column = population

TableName = bsg_planets

Condition = name='Caprica'

SQL Query:

SELECT population

FROM bsg_planets

WHERE name='Caprica';

Therefore, the above SQL query finds the population of the planet named 'Caprica' from the table bsg_planets.

b) Find the first name, last name, and age of people from bsg_people whose last name is not 'Adama'

Syntax:

SELECT Column1, Column2, Column3

FROM TableName

WHERE Condition;

For the given case,

Column1 = fname

Column2 = lname

Column3 = age

TableName = bsg_people

Condition = lname!='Adama'

SQL Query:

SELECT fname, lname, age

FROM bsg_people

WHERE lname!='Adama';

Therefore, the above SQL query finds the first name, last name and age of people whose last name is not 'Adama' from the table bsg_people.

c) Find the name and population of the planets with a population larger than 2,600,000,000

Syntax:

SELECT Column1, Column2

FROM TableName

WHERE Condition;

For the given case,

Column1 = name

Column2 = population

TableName = bsg_planets

Condition = population > 2600000000

SQL Query:

SELECT name, population

FROM bsg_planets

WHERE population > 2600000000

Therefore, the above SQL query finds the name and population of the planets with a population larger than 2,600,000,000 from the table bsg_planets.

d) Find the first name, last name, and age of people from bsg_people whose age is NULL

Syntax:

SELECT Column1, Column2, Column3

FROM TableName

WHERE Condition;

For the given case,

Column1 = fname

Column2 = lname

Column3 = age

TableName = bsg_people

Condition = age IS NULL

SQL Query:

SELECT fname, lname, age

FROM bsg_people

WHERE age IS NULL;

Therefore, the above SQL query finds the first name, last name and age of people whose age is NULL from the table bsg_people.

Answer:

There are additional security risks associated with using cloud computing over local data storage.

Types:

1. Software-as-a-service or SaaS.

2. Platform-as-a-service or PaaS.

3. Infrastructure-as-a-service or IaaS.

marishachu [46]

Answer:

Input code:

car_makers = {'Honda': 'Japan', 'Fiat': 'Germany'}

#add Tesla and USA as corresponding value

car_makers['Tesla'] = 'USA'

#change Fiat entry to Italy instead of Germany

car_makers['Fiat'] = 'Italy'

print(car_makers)

print('Honda made in', car_makers['Honda'])

print('Fiat made in', car_makers['Fiat'])

print('Tesla made in', car_makers['Tesla'])

Explanation:

The first line is a define object in the python code, containing two entries of Honda and Fiat and their respective countries.

The python code adds an entry to the object "car maker" using the bracket notation, the tesla car from USA.

The country of the Fiat car is changed from Germany to Italy, using the bracket notation.

The output of the complete object and the individual cars is given.

output of the python code:

{'Honda': 'Japan', 'Fiat': 'Italy', 'Tesla': 'USA'}

Honda made in Japan

Fiat made in Italy

Tesla made in USA.
