Yo, i need help with question 35....littlehelp?

Far, i did 16 pages for a module and thought it was alot, since people in my school only do 3-4 pages of notes for an exam, some of them cbf . =='' Anyways thx guys

k, thx man :)

kk. thx

mhm, should you care about your Yr 11 notes in Yr 12 tho? Especially when you're doing the HSC?

Title says all...is it worth buying notes/essays from others? Or should I make my own notes? I find it hard making notes because their is so much "stuff" that seems important and you just keep putting them on the syllabus dot-points/expanding your notes even more, which is going to be hard to...

Far, thx man :) I get it now

thx but can you explain it more simpler? I'm not used to cross method :(

Bump... How do i factorise these 2? 4x^2 + 17xy + 15y^2 15a^4b - 10a^4b^2 - 20a^3b^3? thx

kk, thx man :)

Meno...which one? this one? k = 4pi^2m/KT^2

Oh w8 yep my bad. A plane flies 1600km in 2 hours and 45 minutes. Calculate it's speed correct to 3 significant figures? S=D/T? = 1600/2.45? right?

But the answer shows k = 4pi^2m/KT^2 ???

ok, what am i doing wrong here? I'm asked to rearrange this to make k the subject? T = 2pi√m/k T^2 = 4pi^2 m/k <--Divide on this by K? T^2/k = 4pi^2 m KT^2 = 4pi^2 m k = 4pi^2m/T <- I got this =='' is this right?

mhm, thx man. And ye Eduard_Khil, that is wrong bro..(i). XD

Thx

Thx

A bit confusing but ye. I got it now, thx :)

Sorry man, can you explain a bit further?

Bump, Ye thx man :) Can you guys help me with this question? y = (3x+5)^6 √x
