Help me solve a matrix It seems like it's really easy but idk where to start. It's a 5x5 matrix with the main diagonal being all 2s and the two diagonals on each side of the main diagonal being all 1s. The resultant vector is all 1s.

Physics help A 66kg trampoline artist hits a trampoline with a velocity of 7.5m/s. If the trampoline acts as a spring with constant 6.5*10^4N/m, what is the distance he depresses the trampoline. My reasoning: Calculate KE=1/2mv^2=1856.25J KE=W=Fd F=kx x=d (not sure of this) ==>KE=kx^2 1856.25=(6.5*10^4)*x^2 x=0.17m Says it's wrong. Probably because x=/=d or KE=/=Fd.
Matrices in Linear Algebra If I need to do the dot product of a vector and a matrix, is it commutative? ex. I have a 3 by 3 matrix that has a dot next to a 1 row vector with 3 columns. If it's commutative, I can get an answer but if not I can't.

Do people still play Halo 3? I am about to finally fix my xbox 360 and the only games I have are pretty old. I'm wondering if Halo 3 still has a decent player base or if it has been completely overshadowed by Reach and Halo 4. I'm probably going to get Halo 4 anyway since it's like $20 on ebay.
I have a joke Knock knock.

Idioms you use that you think others do not I use "shelling out" a lot. I.E. "I'm not shelling out $500 for the new XBOX!" I never hear it and it even sounds alien to me when I say it. I always say it though. If you didn't know, to "shell out" means to spend a certain amount of money. I use it when I think something is overpriced or when I don't need to spend a certain amount of money on something.
E. coli in my tap water I drink tap water from my home everyday and there was a notice today saying there was E. Coli found in the town water 4 days ago. Am I going to die? :~(
Guild Wars Factions Is it good? Only $5. Is Guild Wars 2 so far superior that I shouldn't waste my time with Factions?

Should I flash my xbox? I finally got around to fixing the E74 error on my xbox 360 and I ran into another problem. Every game that I put in says "Play DVD." I have absolutely no idea what's wrong with it.
