C = {1,2}

D {empty set}

what is C x D?

B = {$, #}

is BxB = {($,$), ($,#), (#,#)}?

and is the cardinality 6?

Write a method named digitRange that accepts an integer as a parameter and returns the range of values of its digits. The range is defined as 1 more than the difference between the largest and smallest digit value. For example, the call of digitRange(68437) would return 6 because the largest digit value is 8 and the smallest is 3, so 8 - 3 + 1 = 6. If the number contains only one digit, return 1. You should solve this problem without using a String.

This is what I have so far:

import java.util.*;

public class Digit_Range{

public static void main (String[] args){

//define user input variable

int user_integer;

Scanner console = new Scanner(System.in);

System.out.print("Enter an integer: ");

user_integer = console.nextInt();

digitRange(user_integer);

}

public static void digitRange (int user_integer){

int digit;

int min;

int max;

while (user_integer >0){

digit =user_integer%10;

user_integer=user_integer/10;//remove last digit

min = Math.min(digit);

max = Math.max(digit);

}

}

}

any help? Thank you.

can anyone help me by showing me step by step how to do this? Thank you so much

I need some advice...

I'm a Computer Science major. I love it, and I'm doing well in my classes. The problem is that now I've become interested in hardware. I talked to my advisor and she recommended that I do Computer Engineering instead because it has both software and hardware. The problem is that I want my major to be in computer science...if I get a minor in electrical engineering would I still be able to work with hardware in the future companies that I work for?

The exercise question says:

Write a program that asks the user to enter the amount that he or she has budgeted for a month. A loop should then prompt the user to ente each of his or her expenses for the month, and keep a running total. When the loop finishes, the program should display the amount that the user is over or under budget.

This is what I have coded so far:

def main():

keep_going = 'y'

#Get the budget

budget = float(input("Enter your budget for this month: $"))

#Determine expenses

while keep_going == 'y':

#initialize accumulator

total = 0.0

#Get expenses

expenses = float(input("Enter your expenses: "))

keep_going = input("Do you have more expenses? "

print("You spent", total, "this month.")

main()

but the running total is all wrong! I don't know what i'm doing wrong..please help!

Thank you!

thank you

Bill can throw a ball vertically at a speed 2.5 times faster than Joe can.

How many times higher will Bill's ball go than Joe's?

A stone is dropped from the roof of a high building. A second stone is dropped 2.00 s later.

How far apart are the stones when the second one has reached a speed of 15.0 m/s?

A helicopter is ascending vertically with a speed of 5.10 m/s. At a height of 120 m above the Earth, a package is dropped from a window.

How much time does it take for the package to reach the ground? [Hint: v0 for the package equals the speed of the helicopter.]

A ball player catches a ball 3.3 s after throwing it vertically upward.

with what speed did he throw it? what height did it reach?

A baseball pitcher throws a baseball with a speed of 43 m/s

Estimate the average acceleration of the ball during the throwing motion. In throwing the baseball, the pitcher accelerates the ball through a displacement of about 3.5 , from behind the body to the point where it is released.

express answer using two significant figures.

what is the integral of (3x-4x^3)^2?

I did it but i got it wrong, can anyone help me figure out what I did wrong?

these are my steps:

1. (3x-4x^3)(3x-4x^3) --- I foiled it

2. 9-24x^3+16x^6

3. 9x-[(24x^4)/4]+ [(16x^7)/7] <-- I used the power rule to find the integral

and can it be fixed?
