No.. it's usually 96+/120. However, it get's harder to go up band 6 as your raw mark increases from there.

same thing? if y is your volume then x is your measurement. For e.g. V = pi.r^2.h - for the volume of a cylinder. Now here you'd either get h in terms of r or r in terms of h. Say you get h in terms of r. You're y here is your V while your x is the r. So if you think about graphing the...

if you draw a graph with a stationary point and draw a tangent at the point, it's horizontal so the gradient is zero. that's why you make x'=0 for stationary points. I don't know/can't explain for x''..

importance of ranking lies in your assessment mark. good rank = good assessment mark. And assessment mark is 50%. So if you have bad ranks then you need to absolutely blitz your externals to push your average up, that is, your (assessment mark + hsc mark)/2 = mark for that subject that's used in...

ohhhh... I get it... thank you very much :D thanks for your help everyone :o

No sorry, I mean I don't understand the translating the vector AB bit..

This I don't understand. Sorry, I really suck at vectors..

I hate them.. :( I drew what I have so far, and I know you can prove it's a rhombus but then I don't know what to do next. I think there's a rule I'm missing.. Any help appreciated =]

Lol. I have weird dreams but nothing to do with school. Few nights ago I dreamt that the guys in my class were terrorists and hurt this baby, and I was a journalist and interviewing a witness. Did not like it. Then I had another dream where my mum deleted all my music off my computer and I...

When I dropped Legal, my teacher wouldn't let me LOL. Took me a while to get him to actually sign it but then he kept a grudge against me ever since. Possibly because I was coming first. I was however heaps happy when I finally dropped it.. free periods and a lighter bag! yayyy =]

I was missing school before I had even left :(

I lost 5 kg because of stress :(

does drawing class as "modelling" ?

well, that's pretty philosphical of you Timothy.. care to elaborate oh wise one? :p

I don't think so. I'm a night person, definitely, but I've realised that I study much better when I've had some good rest.

umm.. i don't think it's a parabola.. EDIT: k maybe it is.. i dunno, i don't do general lol

that's better :)

This doesn't answer the question whatsoever. How is does haemoglobin becoming saturated easily have anything to do with it's adaptive advantage?

carbon dioxide can also travel in the plasma by attaching to haemoglobin and creating "carbamino haemoglobin". Hence, haemoglobin also allows for more CO2 to be removed, helps prevent blood being too acidic, a decrease in enzyme activity and etc etc.. also, more oxygen means more cellular...

Yes.. the last word I wrote today was merely lines, dots and circles..
