I'm new to CS, please give one or two examples.

Also, how would you iterate thru or sort a hashmap using Java's API ?

Any help is appreciated

I finished my high school last year and quit my part time job to go to college (out of state). Should I consider myself received unemployment? I dont know how to answer this question in Turbo Tax

I am asked to find the electric field inside a copper wire in a circuit. I am given the battery voltage, radius of the wire, length, electron mobility and charge density inside the copper wire. I just dont see how these can be used to calculate the electric field

I m currently a CS student at Univ Texas Austin, last month i applied to uconn's engineering department. Today i just got the message saying that im admitted, but not into the engineering program but into a ACES program.

What does that mean? a waitlist?

Can you take major-related courses or only general classes?

Any help will be appreciated

For example,

public static int peanoplus(int x, int y)

{

if (y==0)

return x;

else

return peanoplus(++x, --y);

}

i just can't understand how to find the big(O) of this function.

Any help will be appreciated

I have lived with my uncle for a year in Texas (my uncle owns the apartment) and I have evidence for that (mails, bank statements...), can i claim myself as a texas residence?

Any help will be appreciated.

1. Which of the following statements are always true for our standard shaped costs?

I) If diminishing returns has set in, then AVC is increasing

II) If ATC is increasing, then AVC is increasing.

III) If AVC is constant, then MC = AVC

-->>> I know III is right, I think I and II might be right also, but not so sure.

2. Which of the following must be true about a market with standard shaped supply and demand curves where the demand for the good has increased?

I. There will be a shortage of the good at the original equilibrium price

II. The consumers of this good have more income

III. The new equilibrium price is higher

-->>>> Im thinking I is true for sure, III is also true, but clueless about II

3/ Just a quick question. If supply of labor decreases, will it affect the labor productivity?

Any help will be appreciated

In my microecon textbook there was a problem about how an apple computer's price drops 70 dollars but the demand is still the same. Why? Isnt that unrealistic ?

OK so I was given the function f(x) = -1 + Sum(2 to infinity) ((k-1)*x^k) / k!

a/ Find f'(x).

I got f'(x) = sum(2 to infinity) ( x^(k-1) / (k-2)! )

b/ Determine the function which the power series f'(x) represent.

I never done a problem like this so Im clueless, please help me figure this out.

Any help will be appreciated.

I tried the tests but most of them fail, please help me figure this out,

any help will be appreciated

Sum(0->infinity) ( 2*n^(2/3) )/ ( n^(5/2) + 10n -2)

I tried most tests but they all failed.

Any help will be appreciated

I kinda got stuck on these two questions. Cant seem to figure them out. Any help will be greatly appreciated

7. If a firm is currently producing a good that can be produced in continuous quantities at a point where P > MC, which of the following is true?

a) Society would be more efficient if the firm produced more of the good

b) We are currently at a Pareto Optimal level of output for this good

c) The firm is producing the profit maximizing quantity in a perfectly competitive market

d) A net gain to society would be generated if the firm produced less of the good

e) The firm must be making positive profits.

12. Which of the statements below must be true?

I. If we know the wage is $50, we cannot tell how much labor the firm will hire without knowing the price of the firm’s output.

II. This firm will never hire 10 units of labor.

III. Diminishing returns doesn’t set in until after L = 9.

a) Only I and II are true

b) Only III is true

c) Only I is true

d) Only II and III are true

e) All of them are true

If yes, please tell me how to do that because for some reason i cant get it to work.

I just had my first lecture about object oriented programming today, i kinda understand the main points, but one thing is bugging me: I cant seem to understand the difference between a public class, static class, and just class alone. Please help me understand this concept. A few simple examples will be greatly appreciated.

I got stuck on this question. Any help will be appreciated

I am kinda stuck on this question. Any help will be appreciated

In the rough approximation that the density

of the Earth is uniform throughout its inte-

rior, the gravitational field strength (force per

unit mass) inside the Earth at a distance r

from the center is g r/R, where R is the ra-

dius of the Earth. (In actual fact, the outer

layers of rock have lower density than the in-

ner core of molten iron.) Using the uniform-

density approximation, calculate the amount

of energy required to move a mass m from the

center of the Earth to the surface.

A/ mgR

B/ mgR/4

C/ 2mgR

D/mgR/2

E/ 4mgR

how do you create a variable to keep track of the number of how many times the fib method is called. any help will be appreciated.

import java.util.Scanner;

public class Exercise20_07

{

public static void main(String[] args)

{

Scanner input = new Scanner(System.in);

System.out.print("Enter an index for the Fib number: ");

int index = input.nextInt();

System.out.println("Fib number at index "+index+ " is " + fib(index));

}

public static int fib(long index)

{

if (index ==0){ return 0;}

else if (index ==1) { return 1;}

else

{

return fib(index -1) + fib(index-2);

}

}

}

My company relocated last September and I moved with them to texas; now I have a Rhode Island ID. Is it gonna be easy to transfer my residency to Texas?

For your reference, I am renting an apartment in Texas, also my car is registered in Texas.

I'm doing my physics hw and got stuck on this problem.

You’re driving a vehicle of mass 1250 kg and

you need to make a turn on a flat road. The

radius of curvature of the turn is 75 m. The

coefficients of static and kinetic friction are

both 0.28.

Which of the following statements are true

about this situation? List all that apply,

A. The net force is nonzero and points away

from the center of the kissing circle.

B. The rate of change of the momentum is

nonzero and points away from the center

of the kissing circle.

C. The rate of change of the momentum is nonzero and points toward the center of

the kissing circle.

D. The momentum points toward the center

of the kissing circle.

E. The centrifugal force balances the force

of the road, so the net force is zero.

F. The net force is nonzero and points to-

ward the center of the kissing circle.

ANY help will be appreciated.
