Each to his own - I suppose we each have different strengths.uhhh noooooo 2006,2007,2008 i cld get 90% raw mark in this one im hoping for like 65%..

Yes it was, and the limiting sum was 12Didn't r = 0.9?
h = (b-a)/nno its not.
N is the number of sub intervals if there is 6 sub intervals there is 7 function values...
h= b-a/n and n was 6 sorry man u lost 1 mark :\ but thye carry errors so prolly 2/3
yea r was 0.9.... but it increased by 0.9....Didn't r = 0.9?
yeah i think i got 179 months toocant be bothered working out but you had to use neat algebra to get the "n's" together then use logs. i got 179 months. is this right anyone? you obviously need this to do part iv) but it was a massive number from memory in the 100,000 thousands which made me doubt myself but then i got it.
Fuckin rollercoaster. i fukin had it too but didnt finish it. i dont see how that question tests our knowledge. it just reads how good we are at english in interpretation.
lucky i can do it again.
No, it is growing at 0.9yea r was 0.9.... but it increased by 0.9....
but u no how a was 1.2... well if u multply that by 0.9.... thats 1.9.... which is decreasing... but coz its increasing u add the 1 to make it 1.9... and then wen u multply a by 1.9 its 2.28... shows that its growing.,... I hope that makes sense... well thats how i saw it=/ i think thats correct
but it wasn't growing at an increasing rate - it had a limiting sum (i.e. it doesn't keep growing forever). Meaning yes, each year it will grow nine tenths of what it did the yr before...hence you dont add the one.yea r was 0.9.... but it increased by 0.9....

i concur!h = (b-a)/n
= 300/6
=50m. That's all I know.
CORRECT that is how u do itNo, it is growing at 0.9
It grows to 1.2 in the first year.
And then the second year's height is 1.2 + (1.2x0.9)
Etc.
Well, maybe not necessarily that. Limiting sum only works with x < 1, so it had to be 0.9, because it was clearly limiting.
Thus limiting sum = 12.
you can;t be a 100% but my teacher talso estimated an approx of 95-97 and u can check out that harvey dude who got rights to his paper, who in 2007 got bout 102 and his hsc mark was pushed up to 93% massive difference.I really hope you are right, but 95/120 for 2unit, cmon dude thats ridiculous. Anyways how did you find out what the raw cut off was ? Most of the markers dont know that - our teachers do their best to estimate it.
WTF was up with the decay question about radium? I swear there wasn't even enough information to complete the answer! That test was dodgy...
