Describe the three HTML elements used in a description list

1 answer:

DL DT and DD

The DL element should be used when you want to incorporate a definition of a term in your document, it is often used in glossaries to define many terms, it is also used in “normal” documents when the author wishes to explain a term in a more detail.

The DT element contains inline data and should be used like this.

And Finally the DD definition description element contains data that describes a definition term. This data may be either inline, or it may be block level.

I hoped this helped my dude.

Rideshare companies like Uber or Lyft track the x,y coordinates of drivers and customers on a map. If a customer requests a ride

TiliK225 [7]

Answer:

The program in Java is as follows:

import java.util.*;

public class Main{

public static void main (String[]args){

Scanner input = new Scanner(System.in);

double user[] = new double[2]; double dr1[] = new double[2];

double dr2[] = new double[2]; double dr3[] = new double[2];

System.out.print("Enter user coordinates: ");

for(int i =0;i<2;i++){ user[i] = input.nextDouble(); }

System.out.print("Enter driver 1 coordinates: ");

for(int i =0;i<2;i++){ dr1[i] = input.nextDouble(); }

System.out.print("Enter driver 2 coordinates: ");

for(int i =0;i<2;i++){ dr2[i] = input.nextDouble(); }

System.out.print("Enter driver 3 coordinates: ");

for(int i =0;i<2;i++){ dr3[i] = input.nextDouble(); }

double dr1dist = Math.abs(user[0] - dr1[0]) + Math.abs(user[1] - dr1[1]);

double dr2dist = Math.abs(user[0] - dr2[0]) + Math.abs(user[1] - dr2[1]);

double dr3dist = Math.abs(user[0] - dr3[0]) + Math.abs(user[1] - dr3[1]);

System.out.println("Estimated pickup time of driver 1 "+(3.5 * dr1dist)+" minutes");

System.out.println("Estimated pickup time of driver 2 "+(3.5 * dr2dist)+" minutes");

System.out.println("Estimated pickup time of driver 3 "+(3.5 * dr3dist)+" minutes");

}

Explanation:

The following array declarations are for the customer and the three drivers

double user[] = new double[2]; double dr1[] = new double[2];

double dr2[] = new double[2]; double dr3[] = new double[2];

This prompts the user for the customer's coordinates

System.out.print("Enter user coordinates: ");

This gets the customer's coordinate

for(int i =0;i<2;i++){ user[i] = input.nextDouble(); }

This prompts the user for the driver 1 coordinates

System.out.print("Enter driver 1 coordinates: ");

This gets the driver 1's coordinate

for(int i =0;i<2;i++){ dr1[i] = input.nextDouble(); }

This prompts the user for the driver 2 coordinates

System.out.print("Enter driver 2 coordinates: ");

This gets the driver 2's coordinate

for(int i =0;i<2;i++){ dr2[i] = input.nextDouble(); }

This prompts the user for the driver 3 coordinates

System.out.print("Enter driver 3 coordinates: ");

This gets the driver 3's coordinate

for(int i =0;i<2;i++){ dr3[i] = input.nextDouble(); }

This calculates the distance between driver 1 and the customer

double dr1dist = Math.abs(user[0] - dr1[0]) + Math.abs(user[1] - dr1[1]);

This calculates the distance between driver 2 and the customer

double dr2dist = Math.abs(user[0] - dr2[0]) + Math.abs(user[1] - dr2[1]);

This calculates the distance between driver 3 and the customer

double dr3dist = Math.abs(user[0] - dr3[0]) + Math.abs(user[1] - dr3[1]);

The following print statements print the estimated pickup time of each driver

System.out.println("Estimated pickup time of driver 1 "+(3.5 * dr1dist)+" minutes");

System.out.println("Estimated pickup time of driver 2 "+(3.5 * dr2dist)+" minutes");

System.out.println("Estimated pickup time of driver 3 "+(3.5 * dr3dist)+" minutes");

In step 4 of the CSMA/CA protocol, a station that successfully transmits a frame begins the CSMA/CA protocol for a second frame

DerKrebs [107]

Answer:

There could be a collision if a hidden node problem occurs.

Explanation:

CSMA/CA(carrier sense multiple access/ collision avoidance) is a multiple access method in wireless networking, that allows multiple node to transmit. Collision avoidance of this method is based on preventing signal loss or downtime as a result of collision of transmitting multi signals.

If a node at step 4(transmit frame) sends the first frame, the node still needs to send a RTS(request to send) and to receive a Clear to send (CTS) from the WAP, the is to mitigate the issue of hidden node problem as all frame are treated as unit, so other listening nodes, not detected would seek to connect and transmit as well.
