Write an application that allows a user to input the height and width of a rectangle. It should output the area and perimeter of the rectangle. Use methods for entering the values, performing the computations, and displaying the results. Results should be formatted with one position to the right of the decimal and printed number aligned in a tabular display.

Answers

Answer:

Explanation:

This code is written in Java. It creates a Rectangle class that contains variables for the height and width. It also contains constructor, methods for calculating perimeter and area, and a printInfo method to print out all the results. A test case has been created in the main method which creates a Rectangle object and prints out the printInfo which calls the area and perimeter methods as well. The output can be seen in the attached image below. Due to technical difficulties I have added the code as a txt file below.

Draw a circuit with a 12-volt battery, a 100 ohms resistor in series, and two resistors (each of value 200 ohms) in parallel. What is the total resistance of the circuit?

Answers

Answer:

200 Ω

Explanation:

Hi there!

Please see below for the circuit diagram.

1) Find the total resistance of the resistors in parallel

Total resistance in parallel equation: [tex]\frac{1}{R_T} = \frac{1}{R_1} +\frac{1}{R_2}[/tex]

Both the resistors measure 200 Ω. Plug these into the equation as R₁ and R₂:

[tex]\frac{1}{R_T} = \frac{1}{200} +\frac{1}{200}\\\frac{1}{R_T} = \frac{1}{100}\\R_T=100[/tex]

Therefore, the total resistance of the resistors in parallel is 100 Ω.

2) Find the total resistance of the circuit

Now, to find the total resistance of the circuit, we must add the 100 Ω we just solved for and the 100 Ω for the other resistor placed in series:

100 Ω + 100 Ω = 200 Ω

Therefore, the total resistance of the circuit is 200 Ω.

To do this, you will want to use the data mining software you are using to do which of the following?
a. Identify clusters
b. Identify sequences
c. Classify data
d. Identify associations

Answers

Answer: Identifying sequences

Explanation:

Since the user wants to know if there are any particular activities that the customers engage in, or the types of purchases made in the month before or after purchasing select items from your store, therefore, the data mining software can be used in identifying sequences.

In this case, the data mining software can't be used in classifying data whether into structured or unstructured data. Furthermore, the identification of clusters and associations aren't the correct answers.

Therefore, the best option is B.

cual es el procedimientos para asistir en el transporte publico a personas discapacitadas

Una discapacidad física o motora en una o más partes del cuerpo obstaculiza las acciones y / o movimientos de la persona con discapacidad. La discapacidad puede surgir porque las partes del cuerpo no han crecido completamente o están dañadas (anomalías físicas) o porque las funciones físicas están alteradas (anomalías funcionales).

En la mayoría de los casos, se proporciona una ayuda a las personas con discapacidades físicas graves para que puedan desenvolverse más fácilmente en la sociedad. Alguien con una discapacidad motora severa en las piernas a menudo usa una silla de ruedas. Las personas con una discapacidad motora de las manos (pérdida de la motricidad fina) o de los brazos pueden compensar esto con un manipulador o ayudas especializadas en tareas, como un dispositivo para comer o un dispositivo para girar las hojas.

Así, todos estos elementos deben ser posibles de ser insertados en los medios de transporte público como forma de ayudar a estas personas a trasladarse por estos medios, es decir, los autobuses, trenes, etc., deben estar adaptados para poder recibir allí a pasajeros en sillas de ruedas o con necesidades motoras especiales.

Assume the existence of a Building class. Define a derived class, ApartmentBuilding that contains four (4) data members: an integer named numFloors, an integer named unitsPerFloor, a boolean named hasElevator, and a boolean named hasCentralAir. There is a constructor containing parameters for the initialization of the above variables (in the same order as they appear above). There are also two function: the first, getTotalUnits, accepts no parameters and returns the total number of units in the building; the second, isLuxuryBuilding accepts no parameters and returns true if the building has central air, an elevator and 2 or less units per floor.

The ApartmentBuilding class contains all of the variables listed, as well as constructor and methods, including getter and setter methods for each variable. A test case for the class is provided in the image below with it's output.

       this.unitsPerFloor = unitsPerFloor;

       this.hasElevator = hasElevator;

       this.hasCentralAir = hasCentralAir;

   }

   public int getTotalUnits() {

       int total = this.numFloors * this.unitsPerFloor;

       return total;

   }

   public boolean isLuxuryBuilding() {

       if ((this.hasCentralAir == true) && (this.hasElevator == true) && (this.unitsPerFloor <= 2)) {

           return true;

       } else {
