faaaaaark i couldn't decide whether to split the integral in two or not i should have gone with my gut

same i got a multi wrong because i didnt trust my gut

What did people do for 5 and 9

mcq?

 

[Fabrizio]

mcq?

Yes

 

[anna.linden]

What did people do for 5 and 9

5: C (confirmed with teacher)
9: B (unconfirmed)

 

[hscisbotshit]

Yes

5 i got c and for 9 i got b

 

[Fabrizio]

5: C (confirmed with teacher)
9: B (unconfirmed)

Same

 

[shashysha]

mcq?

5 was C and 9 B i think

What did people get for q7 in mc?

 

[shashysha]

What did people get for q7 in mc?

its A but i changed it last minute from A

 

[anna.linden]

What did people get for q7 in mc?

if 7 was the slope field i got A but they were really awful slope fields there were no constant solutions or undefined solutions

 

[osnola]

its A but i changed it last minute from A

Okay good I got it right then, B and A just both looked so similiar

 

[thomson2354]

5 was C and 9 B i think

Why wasn't Question 5 D? I was thinking if it had a multiplicity of 2 and it was 4th degree, that it needs 2 more roots (I am so hopeless )

 

[Fabrizio]

its A but i changed it last minute from A

Was that the slope field. If so, A

What did people get for q7 in mc?

It had to be A because it was the only one that had a zero gradient along x=0

The quadratic has no solutions therefore only one root

 

[thomson2354]

The quadratic has no solutions therefore only one root

oh right of course.. jee I should not have lost that mark

 

[ItzZoni]

The quadratic has no solutions therefore only one root

Damn that slipped right through my mind, i should've figured that out

 

[Fabrizio]

i went from a 97% average in 3u (rank 2 internally) to getting potentially a low 70s% in externals, what do we think my final mark will be?

its such bullshit. only reason i got the binomial question was because i did pretty much the same question in the day before otherwise i wouldn't have gotten it. They could of included the hardest questions of content from year 12 ex1 and i would of found it way easier then that question

It depends on your ranking in the exam, but as your hsc mark is more heavily dependent on externals, that'll likely become your assessment mark, but a raw mark of 70 will still scale up to high E3/ Low E4 potentially for your final HSC mark, so I wouldn't stress

Can someone confirm that volumes is 3(pi)root3/16
