I asked this question before but got the sums of money wrong, this is what I meant to ask.

In the game show Deal or no Deal the contestant sometimes has a chance to swap boxes at the end. If there where 2 boxes left and one has £50 in and the other has £250,000 in it would it be advisable for the contestant to swap his box?

Calculus Help

I need some help on math. I have made the sketches already. I need up setting up the integrals, mainly. I can solve the math from there.

Disk and Washer Method Unit

Make a sketch and show integral.

1. Find the area bounded by the curves: http://img135.imageshack.us/img135/3852/number1oi6.png

a. Rotate this area around the x-axis (means find volume of solid formed)

2. Find area bounded by the curves: http://img385.imageshack.us/img385/8542/number2ms5.png

a. Rotate this area about x-axis (means find volume of solid formed)

b. Rotate this area about the y-axis (means find volume of solid formed)

The integrals have limits and u-substitution can be used.

Thank you!

Dear All:

I have another question about Parabolas here are the following examples:

P1(x)=X^3+5x^2-26x-120

P2(x)=X^3+X^2+89X+231

P3 (x)=320-88x-2x^2+X^3

P4 P(x)=(x-2) (x-3) (x+4)

I know that are done differently because this cubed equation the squared I do get bit confused.

I really appreciate all of your help and I will be probably needing more of your help in the near future.

Please if you can break this down to me step by step. Thank you so much!!!
