Can you do mock paper 2020

[@samuelbrodie1060]

Hi, great video! For question 6bi, do you need a negative sign in front of the t in the exponent?

[@handy4689]

At 23:00, I used the model V = Ae^-kt and it gave me the same answer for part b(ii). My model is different to yours so I don't know why I still got the right answer, did I do something wrong? I'm a bit confused

[@AITutor]

Nah you're good. If you think about it, you can rewrite e^-kt as (e^k)^-t. But e^k is just a constant (e) to the power of another constant (k), so surely that is just a constant? I could therefore set b = e^k and we'd get the same answer 👌

@@AITutor Ahh that makes sense, thanks. Btw would you be able to privately go over solutions for autumn 2020 papers? (I understand you can't release to public atm)
