useful forum hey daniel while you are here how would you do prove that n^5 - 5n^3 + 4n is always divisible by 120 when n is greater than or equal to 3 and prove that there are no integer solutions to the equation 2x + 4y = 5 since both 2 and 4 are even numbers, does that alone prove...

yes also you didnt need to substitute if you think about it, you already had the consecutive pairs n, n+5, and n+7 n being odd, you are adding 1 to make it even, than another 4 if that isn't divisible, the other pair adds another 2, so it must be divisible if the other wasnt.

yea tu it sucks balls (this is phillips)

ah, thankyou! pythagorean theorem. Thanks a lot :)

you would use the radius of the Earth and 35, would you not

sorry, I don't know where to take it from there :o

http://www.etienne.nu/imagepuz/4845.htm How would I go about solving this? I know it involes trigonometry, but I donnot know how to get the proper answer.

ah ok, so the pole is 5kg is it correct in saying the tension in the wire is 276.64 N too?

how exactly would i model the forces acting on the wall? the hypotnuse is not 90degrees, so I am not sure how i would handle that

http://s87050427.onlinehome.us/scan.jpg how would I do this, and how would I solve for tension in the wire? What i did was completely wrong, and I appologize in advance for my horrible horrible, handwriting. Thanks in advance! oh, and a quick response would be greatly appreciated, my exam...
