here is cleaner copy of paper

i added a pdf of the cognito solution into post #290

the cognito also agrees with the starboy/jeff>>=/beyondtutoring answer for mc

another sol: https://www.cognitotuition.com/blog/2024-hsc-physics-exam-paper-exemplar-answers-solutions this one for rest of paper too attached as pdf

well beyondtutoring tiktok agrees with them https://www.tiktok.com/@beyondtutoringau/video/7434387170330234132 i attached a zipped mp4

my confidence is growing for this because i got other answers from another bro which is exactly the same as starboys this from jeff >>=

here is explanation for 15

dunno if rest of starboy's is right though, better check

starboy answer is D also the 2020 q19 answer is C so i don't think the 2024 q15 can be C some bros were sayin they the same so has to be C but they not the same so not C

they look similar but are different

starboy's mcq answer: CBCDACBBBCDBABDACDCC so 17, 19, 20 are all C according to starboy

paper

another way to understand this is the position of the asymptote so for y=lnx asymptote is x=0 translate to left by π and asymptote is x=-π then dilate horizontally by factor 3 and asymptote is x=-3π and the only one with that asymptote is A

it would be D if it were the other way around like this dilate horizontally by factor 3 first, so replace x with x/3, then it is y=ln(x/3) THEN translate left by π, so replace x with x+π and it is y=ln((x+π)/3) i sometimes disagree with mathgpt but in this case it is correct

u are right i put into mathgpt.org and it make solution so A
