Incorrect anyway do doesn't matter

ohh nah like i got the correct answer its just the fraction wasnt simplified to 1/3

 

[hehe43]

Btw mc answers are: DACCBCBADB
However some say 10 was C

 

[WeiWeiMan]

That's incorrect I knew a guy who got 67 and he didn't sr

Damn crazy
No one got 100 last year tho I would’ve thought cutoffs would be lower

 

[rainbowspoon1]

are solutions out yet?

Nah cut-offs would never go that low

LETS GOOOOO

Officially no, if you have certain questions ig just post em

 

[Iceyscreen]

anyone remember what they got for the 2023C45 question

 

[blob063540]

anyone remember what they got for the 2023C45 question

p = 2024 and q = 81

 

[kms1234]

anyone remember what they got for the 2023C45 question

they are multiple answers depending on how you simplified the comb

Can someone please but my conscience at ease, i spent 10 mins on that volume question and am properly about to neck myself

Simplification is not required / mandatory outside of "show" questions. Both one over root 2 and root 2 over 2 would be accepted, for example. I am confident that both + ln(1/3) and - ln3 would be accepted. Not changing 12 / 4 to 3 is careless, and leaving 4 / 12 instead of 1 / 3 isn't good either, but are these really worth a whole mark penalty when the expression is numerically correct? I'd doubt it.

okie cool hopefully the marker is kind, cause i think i did the same thing in 4u lmao

what do guys think a 53/70 will scale too

 

[mmmmmmmmaaaaaaa]

ACTUALLLY CRACKED - thats probably near top of state

What would be the minimum for a state rank?

sr would be min 67-8/70

You gotta add the cylinder

whatttt i did i had curve at 800pi and cylinder at 400pi

 

[Aminza21]

p = 2024 and q = 81

pretty sure q is either 1944 or 80 (not 81 or 1943) coz u gotta add one/ subtract one by the n-1 identity

Maybe you expanded the as instead of as ? This would get the 800pi but miss the log term...

 

[notme123]

no you just take the maximum of the bottom values, you dont add anything to them

 

[Luukas.2]

pretty sure q is either 1944 or 80 (not 81 or 1943) coz u gotta add one/ subtract one by the n-1 identity

​

And so there are two equally-acceptable solutions: p = 2024, q = 81 and p = 2024, q = 1943.

lucid's solutions are attached.

epicmaths also put up his solutions in this post https://community.boredofstudies.or...lution-speedrun-send-help.405894/post-7515199 which was from the youtube

I haven't checked these so some may be wrong.
