In video games it is often required to be able to determine if two balls have collided. Create a program which accepts the radius and the center (x,y) of each ball and states whether the two balls have collided. Hint: Draw and label all the known information for situations (2) when the balls have collided and when they have not collided.

hey guys can u please help me with this question.. i've lost ma book and its too late to buy another one.. so some body please help me!

this is the question:

Kathryn bought 600 shares of stock at a price of $21.77 per share. She must pay her stockbroker a 2 percent commission for the transaction. Write a program that calculates and displays the following:
The number of shares purchased
The price per share
The amount paid for the stock alone (without the commission) (number of shares x share price)
The amount of the commission (amount paid for the stock x the commission percent)
The total amount paid (for the stock plus the commission) (amount paid for the stock + the amount of the commission)
The program should neatly display a text label along with the value. For example:
Shares purchased: 600
The program must perform the calculations. It is not acceptable to perform the calculations on a calculator and just use the program to display the results. I should be able to modify the numbers in the program and have it correctly compute the result.

Need Help On Email Validation, Asap Please.

Hey, basically I have my assignment due in 2 and a half hours and I cannot work out how to validate a email address. What am I doing wrong? Been on the net for a couple of hours lurking to find some answers but now I am even more lost.

Bit of information:
Basically I need to work out how many tables are needed for a class room depending on the desktops and laptops used and how many roils of coils are needed blah blah blah. Then comes the tricky part (for me anyways) asking the user to confirm or cancel the order everything works up to confirming the quote and then validating the email address, canceling the confirm button works so I'm assuming it's just the validating that I have destroyed.

Any help would be awesome, assignment is due very soon and no sections of code are helping me on the net.

Code:

function confirmquote()
{
var answer=confirm("Do you want to recieve a quote?");
if (answer==true)
  {
  var emailID=window.prompt("Please enter a VALID email address or type quit to exit");
  }
else
  {
  alert("Quote has been rejected sir, please refreash to start order agian.");
  }
}

}
function CheckEmail() 
	{
		emailID = document.f1.Email.value
		AtPos = emailID.indexOf("@")
		StopPos = emailID.lastIndexOf(".")
		Message = ""

	if (emailID == "") 
	{
	Message = "Not a valid Email address" + "\n"
	}

	if (AtPos == -1 || StopPos == -1) {
	Message = "Not a valid email address"
	}

	if (StopPos < AtPos) {
	Message = "Not a valid email address"
}

if (StopPos - AtPos == 1) {
Message = "Not a valid email address"
}

return Message
}

(ALL IN THE HEADER TAG)
Code:

var worknowplease = confirmquote();
var emailID=checkemail();

(Last few lines of code before [/body])

I have no idea what the validate email is trying to do in the coding, but I'm still very freash on JS.

Thanks you for reading and if you can share any possible solutions to my problems.

Thanks agian.
