dh/dt = -k

right?

and 5. b) iv) was 100 days, right
That's what I got...
Honestly though, when I did it, and I saw that the times were exactly the same from 3-2 and 2-1, I doubted whether it was correct... There was no time to re-attempt it lol.

You're pretty awesome on the 4U forum here, so maybe this consensus means we got it correct?
Hope so =]

Yes, exactly what I got. And to the person above me, the result makes sense because h and t are related by a linear function, so the function has a constant gradient throughout, which means equal time intervals result in equal change of height/depth.

That's what I got bro.

Man.. that paper was harder than previous years T_T

Did not get the last 4 marks from Q7 and could not complete various things from other questions.

ARG at the binomial Q6 >_>

Lost at least 15 marks so far.

E4 out of reach?

i think by inspection 100 days is correct, because dh/dt is constant .'. h varies with respect to t at a constant rate, so it makes sense that between two equal intervals its the same

Paper was pretty straightforward, apart from binomial part of q6 which fucked me in the balls hard. Fair paper all in all though.

Q1-4 was fine.
Q5, 6 and 7 not good at all.
I guess i should have dropped extension.
