Lol ok that explains it

Ohhhhh I think you learn this is integration or something? Because I haven't done that chapter yet. Sorry about that. I just saw it in past papers and thought it was part of calculus or whatever. Thanks everyone, really appreciate it :)

Thanks heaps dude. But why didn't you do this, when you derive the v=e^x, why didn't you do v'=xe^x-1 ? I was taught to do it that way --- helpppppp I have an exam tomorrow :( Thanks in advanceee

How do you derive this? It's done weirdly in the solution. Like especially how do you derive the denominator? Is it xe^x-1 ? thanks

Yeah man defs. It distorts one's way of thinking. Best not to experiment with "artificial energy boosts" during hsc. Stick with water for hydration and lots of fruits and vegetables, without the natural vitamins not boiled out. :)

If you do them in the holidays, then you can't give them to anyone to mark. And who will mark your 10 past papers or however much you do? Should we just assume we're answering the questions correctly?

Thanks sooo much guys <3

What steps do I take to do part ii ? Thanks

Thanks, how do I do the first one?

How do you do these? For the second one, does the discriminant need to equal zero? If so then I get m=4 and m=-8, what is right? thanks

The last question of the listening task was "Compare" and I didn't actually say "similarly" etc, I just wrote about the 2 texts. What is the max mark I could get for that 5 mark question. :(

Dude it's never too early to start. Besides, you'll be at an advantage.

Hmm but in total I have 7 points so 3 above and 4 below is that incorrect? Ok, I wont join the dots.

So do I rule the line of best fit and rule by joining the dots? 2 lines? Like this?

independent variable: mol/L (concentration of electrolyte) dependent variable: change in mass for electrolytic cells.

Hi can you show me what the line of best fit wou;ld look like for this? Do I need to rule it or just rough draw it? Also, ,do I need to join the dots? Cheers

yeah bro I tried that but I didn't get it.

Yeah answer is 11, but I'm getting -9 :(

How do I do this? I tried using logs but it got messy :( thanks.

The answer's probably wrong but the process should be right. I was focused on trying to squish it all on one page lol soz
