Given that a function receives three parameters a, b, c, of type double , write some code, to be included as part of the functio

hoa [83]

Answer:

public static void quad(double a, double b, double c) {

double D = (Math.pow(b, 2)) - (4 * a * c);

if (D<0){

System.out.println("no real solutions");

}

Explanation:

The code snippet above implements the function in Java programming language

As required by the question, the line double D = (Math.pow(b, 2)) - (4 * a * c); evaluates b squared" - 4ac and assignes the value to the variable D

An if statement is used to test if D is less than 0, if this is true the message no real solutions is printed

Write a program with class name Digits that prompts the user to input a positive integer and then outputs the number reversed an

mr Goodwill [35]

Answer:

Written in Python:

inputnum = int(input("User Input: "))

outputnum = 0

total = 0

while(inputnum>0):

remainder = inputnum % 10

outputnum = (outputnum * 10) + remainder

inputnum = inputnum//10

total = total + remainder

print("Reverse: "+str(outputnum))

print("Total: "+str(total))

Explanation:

This prompts user for input

inputnum = int(input("User Input: "))

This initializes the reverse number to 0

outputnum = 0

This initializes total to 0; i.e. sum of each digit

total = 0

The following iteration gets the reverse of user input

while(inputnum>0):

remainder = inputnum % 10

outputnum = (outputnum * 10) + remainder

inputnum = inputnum//10

 This adds each digit of user input

total = total + remainder

This prints the reversed number

print("Reverse: "+str(outputnum))

This prints the sum of each digit

print("Total: "+str(total))

Requests to access specific cylinders on a disk drive arrive in this order: 24, 20, 4, 40, 6, 38, and 12, and the seek arm is in

GarryVolchara [31]

Answer:

The time required to seek using First come,first served algorithm is 876 milliseconds.

The time required to seek using Shortest Seek Time First algorithm is 360 milliseconds.

The time required to seek using LOOK (initialing moving upwards) algorithm is 348 milliseconds.

Explanation:

Part a,b : First-come, first-served:

The order of the cylinders is as 10, 22, 20, 2, 40, 6, 38

10 + 12 + 2 + 18 + 38 + 34 + 32 = 146 cylinders = 876 milliseconds.

ii) Shortest Seek Time First:

The order of the cylinders is as 20, 22, 10, 6, 2, 39, 40

0 + 2 + 12 + 4 + 4 + 36 + 2 = 60 cylinders = 360 milliseconds.

iii) LOOK (initialing moving upwards):

The order of the cylinders is as 20, 22, 38, 40, 10, 6, 2

0 + 2 + 16 + 2 + 30 + 4 + 4 = 58 cylinders = 348 milliseconds.
