make your goal to make 2 people’s day better . Then they have the same goal and 4 people are having a better day because you made an attempt t9 make two people’s day better

tigerian as wise as always thank you my king

this graph is actually so applicable to real life situations. I hope that everyone's grades go up like that

had anyone figured the answer to the last question in the maths adv cssa? or did someone already did and i just couldn't be bothered to read the history of this discussion.

if I remember correctly we had y=x^2 and y=ln(x)+k. I just differentiated both functions and made them equal to one another and solved for x. Because the tangent at A is the same gradient for both curves. With the x co-ord you can sub back into x^2 and you have the (x,y) of point A and it all flows from there. can find k as such. the 2nd part with the integral was simple once you had k.

Sorry I didn't mean it as like 'special needs' I just meant that some people are good at better at english or worse at biology or something

na no coming back from wat u said she deep fried you with that response tho maybe if you get a 99 atar you can get your get back

socialism seen a moment ago hazzrat a moment ago hop off my case

 

[Scryne]

You guys reckon I could still pull off a raw score of 70 in math standard assuming I averaged 50 in internals and got an 80 in the HSC?

fucking moderating at 9:11pm people were doing greater feats at 9:11 bro

differentiation makes sense, I unfortunately didn't think of that. Thank you!

you either see it or you don't, thats the annoying part.

thats what I did as well
@Dzeeshr do you think you got anything wrong

probably not. aside from transcription errors, or misreading questions. Q9 or 10 may have messed up though.

Damn… did this tho but solved for A instead of X what was I thinking (subbed A in too early idek how)

i did that but i kept getting 0.47... instead of 0.04... i spent like 30mins staring at my page trying to figure out where i went wrong and i never found out why
oh well at least i got 2 or 3 marks for it

 

[Kat.crazi]

Our school gave replacement questions for stuff we hadn’t done and I found those harder than a lot of questions on the actual paper bruh

 

[fluffy_unicorns]

I didn’t think of solving with the derivatives i still wrote the intergrals, but couldnt complete solving them ofc bc i didn’t have A or k. Hopefully i’ll still get a mark or two still tho

depends on ur rank, could either get u a 60 internal or 85 internal, all depending on how ur cohort performs

can i cover a whole years worth of biology content in one day

 

[Kat.crazi]

Girl if u can’t I can’t
and I have an exam the day before

 

[alphxreturns]

yes, as the wise man once said
