Re: HSC Exam Timetable why not? wouldn't it be better to get it out of the way first.

This question might help.... A population in a certain city is growing at a rate proportional to the population itself. After 3 years the population increases by 20%. How long will it take for the population to double?

yep it's the exact question

I havn't really got a specific aim but i just want to achieve what I personally can. If that means getting 95 then it's all good lol :haha:

anyone?

its compulsory in my school but if you don't want to do it you can choose catholic studies (not UAI subject) which is a total joke lol.

The population of a city is P(t) at any one time. The rate of decline in population is proportional to the population P(t), that is, dP(t)/dt=-kP(t). (a) Show that P(t)=P(t0)e^-kt is a solution to the differential equation dP(t)/dt=-kP(t). (b) What percentage decline in population will there be...

you need to change the x-values to u-values because you are now intergrating u-values because you made u=2-x.

lol i think i worded that wrong.....well you know what i mean.

well if you say so....

yeh the highest on BOS will definitely get above 99.95 if not 100! what makes you say that someone like Namu will choke in the hsc?

no worries.

yeh this is what i got... y=sqrt(400+x^2) dy/dx=x/sqrt(100+x^2) dy/dt=dy/dx.dx/dt =40/sqrt(400+40^2).3 (when x=40) =2.68..... is that right?

he means trying to beat the people from your school so you can improve your ranking within the school.
