1. ## HSC 2017 Predictions Thread [MX1]

Post predictions and discussion about upcoming MX1 exam.

Hopefully no hard binomial like 2013's one which was deadly, and hopefully no ambiguous perms and combs/probabiity. I reckon we'll get a hard circle geo or projectile

Maybe a hard graphing or harder application of calculus.

Agreed, I reckon they'll chuck in a harder application of calculus Q - the ones with rates and volumes, something to do with a cone or cyliner V etc.

Inverse functions and Projectile. Inverse functions something along the lines of SydneyGrammars 2016 final question.
No binomial theorem

Honestly, I really hope there's no induction question similar to the one in Sydney Boys 2017 trial, the solution never came to me yet it was so simple in the end.

r u referring to question 13.d?

I guess so cause that's the only induction q in that paper haha

Yeah its probably that, it had an unusual way of solving to my merit

A formula for the rate of change in a population of a certain species of animal is given by P=200+1600e^-kt. If the population reduces to half after 56 years, find how long it would take to reduce to a quarter of the original population.

Thank you
