Exam 2

[some dude]

ok so i copied some of my answers to the "harder" questions. see wat you guys think:
last question for Geometry: height=42m and Volume=438m^3

maximum almonds question: 125g of almonds(x)

walkie talkie? question(graphs): 1.38 hours

half colonies question (matricies): during 5th year

last matrices question: 400 juveniles and 0 adults

[99.96]

I got the same as you for everything. Except geometry cos i dont do it

[Furbob]

dammit, did 120g of almonds... would I get 1/2 marks for that?

[Haras_Etak]

I got everything the same except for the damn walkie talkies. Sorry, but I don't think you'll get any marks for 120gm.

[99.96]

can you even get 1/2 marks in further?

[Haras_Etak]

No, I don't think you get half marks. But the question was out of 2 so if you showed some working out maybe you could get 1 mark?

[Furbob]

woops, it was 2 marks worth I think, I meant getting 1 mark for that out of the 2 not half

sweet although i think i might of got a really silly mistake for the second trig question. might of wrote down 152 instead of 208 degrees   heres hoping i did put 208! other than that i thonk i aced it:)

how did you get h=42? wasn't it just h/18 = 3.5/2?

[davidle_10]

h-18/h=2/3.5 or the other way around h/h-18=3.5/2

How did you get 400 and 0 for the last matrices question? I was positive that it was 0 and 100

You need to do the inverse twice, as 100 Juveniles and 50 Adults is at the end of the 2nd year, 0 Juveniles and 100 Adults is at the end of the first year, we needed to find the initial S₀ state matrix.
