Booya! Thank you, berkeman!

Homework Statement Ok, so I have a=2bc^3 and b= c/f but I want to get rid of the b's. Homework Equations So I know I do a=2(c/f)c^3 The Attempt at a Solution This is where I get lost (and feel stupid). Does this get simplified to (2c^4)/f? Or, is does it stay the same because...

yes i think so. i copied the question exactly. iRaid- how did you get from d/(d/t1+d/t2)=t1*t2/t1+t2?

i believe so. the question is asking how long will it take to get to baggage claim if the machine is working and you are walking on in.

1. ok, my dad and I are trying to solve this problem, but we're both having difficulty: "When the moving sidewalk at the airport is broken, as it often seems to be, it takes you 50 s to walk from your gate to baggage claim. When it is working and you stand on the moving sidewalk the entire...

thanks flyingpig, you've been a great help!

sorry, i meant 1+1=2. you've been really helpful, and don't let me keep you awake! :)

so then to prove (2), we would have to do n+1, which, in our case, is 0+1=1 and that would give us 1-r^2 / 1-r right?

ooooooh, ok

ok...so when the right side equals the left side... what does that mean?

but what does it mean on the LHS?

does it mean that it's "proven"?

honestly, i don't know

then the right hand side will equal 1. right?

n has to be greater than 0
