If you don't mind me asking, how do you get these resources? Is there some underworld HSC group I don't know about?

no one knows... But if it is, then it's hard for everyone and alignment will compensate

By the pigeonhole principle, you only need to know 3 topics in which finance can be excluded! Applied mathematics baby

Thats reassuring, thanks!

Do you think it's necessary to remember exact, text book definitions for certain terms in business? Or is it better to have a solid understanding and describe the terms in your own words. I understand all the concepts in business but sometimes have trouble wording it.

I got a positive which was weird but didn't have enough time to look back on it. You?

ext1 doesnt have financial maths

Thanks for this

ah, ok. I was more so referring to the entirety of q26. If i hadn't doen extension 1, i would never make the connection to substiute y(t)= 0 for 26b. This is very similar to ext1 projectile motion questions, so yeah

No. The +100 in the equation y(t) accounts for that. But this question is fk'd up for advanced honestly, it's more of an ext1 question

yep, this
