Lol that's a pity and ye my math teacher marks it really quick, in like 3-4 days haha

ye that's exactly what I said lmao And I expect around 10 or 15 people doing it next yr

cause bio is boring

well I was thinking of starting 4u, phys, chem like reading some textbooks but now yearlies finished I just feel lazy lol

lmaoo found out that I got 99% in maths 3u yearlies, lost a mark cause I wrote an unnecessary incorrect restriction on x lol. Oh well learnt a lesson here, not to write any further unnecessary stuff haha

We did this prac, Its AgNO3 (aq) + NaCl (aq) -->AgCl (s) + NaNO3 (aq) You can decompose this AgCl with light; 2AgCl (s) --> 2Ag (s) + Cl2 (g)

We didn't lmao, we're too slow at the science subjects Only finished like the first 2 focus area in water haha. But good thing I can start yr12 work by myself after the yearlies

Re: HSC 2016 2U Marathon f'(x)=nx^(n-1) f''(x)=n(n-1)x^(n-2) f^n(x)=n!•x^(n-n) =n!

3 weeks no school cos exams lel. Except 2 hours every dew days haha

lel thanks for the links

wut https://www.wolframalpha.com/input/?i=6*10%5E-7*-1.602*10%5E-19 you probably divided it (dividing it gives me your answer) instead of multiplying it to find the force haha

I think you forgot to put a -19 on the calculator haha. I'm getting -9.612*10^-26 N

use the formula E=V/d E=24/0.2 = 120 NC^-1 you can see a quick derivation of that formula if you search it up

I meant I* wasn't talking about the same school lol

we got like 175 m8

Re: MX2 2016 Integration Marathon I= \int \frac{\sqrt{2+x^2}}{x}$ d$x \\ =\int \frac{2+x^2}{x\sqrt{2+x^2}}$ d$x \\ $ let $ u=\sqrt{2+x^2} \Rightarrow $ d$u=\frac{x}{\sqrt{2+x^2}}$ d$x\\\therefore $ d$x=\frac{\sqrt{2+x^2}}{x}\\I=\int \frac{u^2}{u^2-2}$ d$u = \int 1+\frac{2}{u^2-2}$ d$u\\ =...

a=(v-u)/t = (20-15)/4=5/4ms^-2 F=ma =1000*5/4 =1250 N in the direction of it's motion

woah congratulations mate! get that top 5 ranking haha

Part 3: If you sub b into the original equation, it must turn out to be 0 (since b is a root). So b^2-3b-13=0. Now multiply each side by -2, you get -2b^2+6b+26=0. Now subtract 26 from both sides and rearrange the LHS to get 6b-2b^2=-26. So you can see the LHS is exactly what the question wants...
