From here it is simple enough. As k and m must be integers, All factors of 15 until 100: 15, 30, 45, 60, 75, 90 All factors of 27: 27, 54, 81 Hence, the number of possible combinations that satisfy the equations are 6*3 = 18 (i think at least)

Hmmm interesting question. It is important to remember that there are two components that allow a reaction to happen: the kinetics and the thermodynamics. Here we are specifically dealing with the thermodynamics, where two important terms are used to describe the conditions required for a...

Yes I like the above suggestions as a very good general solution and sometimes you might need more. For example, is it you are making a lot of silly mistakes and if so, is it due to time pressure or confusion between multiple options. Think about every step you take in an exam while doing each...

Anyone Toblerone...

Library's collection (online or physical copies) are always the best for this. In my local library they had the yr 11 and 12 in focus textbooks. You should go check there and some closer suburbs. I mean a textbook is a good way to draw boundaries and i think it is important to have.

This is a compound interest question. So use the formula in the form A/P = (1+r)^t, where r = 0.14, A/P = 20. -> Solve this eqn and you should be good.

I agree with what quickoats said. In my eyes, if you want a really fast-paced and high pressure environment come to UNSW by all means. If you prefer a slower and calm environment come to UTS. Personally I feel like UNSW is sort of a mess, but has very good lecturers and students. UTS is not very...

That sounds far more reasonable and is probably close to discovery as well (maybe idk). But like making people live forever is kinda ridiculous.

I think the simplest resources for these are past HSC papers, past trial papers and question banks on thsc (even atar notes is pretty good). Funny how atar notes is just replaced by ********* lol

Bro, you can do this. I was sleeping in yr 11 chem - if you're able to pass your prelims, then you can definitely do this. Chemistry is really hectic but the most important thing is really getting down the concepts of moles and the entirety of last chapters. Quintissential these two - general...

Lmao $80 per hour. I feel like im ripping off the student at any age, at any time with how much ever experience. Like it causes me physical pain to charge more that $40 per hour. I would not even be happy - but that aside, no matter what kinda student you are, when coming fresh outta high school...

Calm down lad. Its like jumping off Everest and trying to survive. You prolly have better things to do. This sounds very obsessive and you should really chill. :p I really wonder what you want to do by living such a long life...

PHYSICS: I personally think that all of mod 4 is completely relevant for yr 12 - especially when dealing with the first part of electromagnetism. In waves, the only thing you might need is standing waves. Mod 1 and 2 - eh, just revise the key concepts but you cannot do yr 12 mechanics super...

I actually don't think you can prove ln(2) being irrational with the exact layout used in ext2 because ln is basically log(e) where e is a transcendental number (i.e. not an integer) so dont worry too much about.

Hey... um its not m abs(B/(B-18k)) = k/m, its ln(abs(B/(B-18k))) = k/m. Sorry for the terrible handwriting

Hmmm a slight modification to the blue underlined statement to account for all log irrationalities would be the following: As 5 and 13 have no common factors (as they are both prime number), there exists no real number where a = b. This is applicable to the 5 10 case if we do the following...

So i remember doing this question and I couldn't figure it out then but I have now. I have put the solution down below. Anything you didn't understand, shoot a reply to this... here goes. Ok so I would even think that many people will get up to this point. But here's the little trick - the...

If you're using this for a scientific investigation - use google scholar (a bit more reliable although I think the above site summarizes the stuff nicely) - although it will be a bit difficult.

Mod 8 is still lacking - so manny errors

I feel like i've heard this before @Hivaclibtibcharkwa. Enlighten her. (i dont have solutions sry)
