I reckon I got 50-60.. Oh God
i got y=3.....fml.....y=1 i hope
That's what I got...dh/dt = -k
right?
and 5. b) iv) was 100 days, right
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.dh/dt = -k
right?
and 5. b) iv) was 100 days, right
LOL =/...well i was completely lost...sitting there full trying to figure out how to draw the graph, wasted too much time on thatomg
me too
am i lost or what
-.-
That's what I got bro.dh/dt = -k
right?
and 5. b) iv) was 100 days, right
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 sameThat'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 =]
nah brotherThat'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?
yehh i got that 2! wen i saw dh/dt=-k i thought i got it wrongggYes, exactly what I got.
thats what i got5. a)
iv)
t = pi/3n
??
