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

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");

A computer’s memory is composed of 8K words of 32 bits each. How many bits are required for memory addressing if the smallest ad

victus00 [196]

Answer:

The minimum number of bits necessary to address 8K words is 13.

Explanation:

You have the number of words to address that is 8000 words, a word is the smallest addressable memory unit.

8000 words can be addressed with $2^{n}$ units. Now you have to find the value of n that approximates to the number of words.

$2^2=4\\2^4=16\\2^7=128\\2^{10}=1024\\2^{12}=4096\\2^{13}=8192$

So you can see that 13 bits are needed to address 8K words.
