what about the min. area

 

[Iceyscreen]

defo harder, god scaling incoming hold your balls

You've made my day, consider my balls held

 

[ilovescottishfolds]

what about the min. area

we didn't have to find the minimum area but just the minimum x value and i got x = 12

I swear I was tripping bc those questions were like straight up harder than all the questions from previous years it was like a combination of all the hardest questions

What did u guys get for the M value for the withdrawal question

It felt like instead of a few B6 oriented questions to separate students from B5, it was the short answer section

 

[Rattlehead15]

What did u guys get for the M value for the withdrawal question

12 dollars or 120 dollars or smth but Im probably not the best source

 

[Cathode_RT]

What did u guys get for the M value for the withdrawal question

187 something? or something around that i forgor
Edit: I cant remember exactly, it ended up working out, so it was definetly 100 something, and I can probably confirm anyone else's answer

 

[Iceyscreen]

what about the min. area

I'm genuinely curious how did everyone do this one, i was so lost, I had a negative area O-o

 

[Iceyscreen]

How about for the geometric sequence, did u guys get r=1/4 and -1/4 and a was in the 3000s?

yuppp i think a was 3072 and -3072 but i can't fully remember

 

[Cathode_RT]

what about the min. area

A = 22u^2?
x = 12

you had to make a formula for the area of the concrete path with x and y. Given you already had found the area of the garden (50) by x and y the area formula was A = Total area - garden area = xy - garden area (cant remember exactly)

 

[Iceyscreen]

Was the trig Q with (θ-60) like -60, something else & 300??

Yeahh i had 0,300,360

 

[lizzygrant2937]

should be fine if I calculated the area as well.. lol

Ah cool thanks, hopefully can snag a working out mark

 

[amy.q18]

what did u guys get for the regression line equation and the justification

 

[Anaya R]

Does anyone have a scan of the exam paper?

 

[Cathode_RT]

what did u guys get for the regression line equation and the justification

y = -10.4x + 236

Justification - You get negative energy output at 23*, so it doesnt work at higher temps
