For 29b ii. I put 60, as I thought itll b silly for someone to get 59.8 in a test, so you rekon itll still b marked as correct?
The rest seems to be right

26a) CosC = (A^2 + B^2 - C^2) / 2AB
CosC = (53^2 + 66^2 - 98^2) / (2 * 53 * 66)
C = 110 Degrees
28a) 1/2abSinC (Area of a Triangle)
1/2 * 75 * 60 * Sin71
= 2127m^2
29a) 5W + 20 - 6W + 3 = 15
-W + 23 = 15
-W = -8
W = 8
29b)i) 5.5 (I think)
29b)ii) 62 (Is only correct if 29b)i) is right.)
29e) I can't remember the exact value but I think it was approx. $900,000, and he could pay it off in 14 years.

All right, except this one i believe. I dont think you were suppose to use the Future Value. You'll suppose to use the Present Value to calculate if he was able. In which he wasn't by like $15000 or so.

Yeah I was just reading that while I was marking my own MC. I think I got high 70s. One can hope
Thats good man. Im happy for yaYeah I was just reading that while I was marking my own MC. I think I got high 70s. One can hope

For 29e I calculated the interest per month ($1500 on a $300,000 loan at 0.5% per month) and multiplied it by 120, which is half of 240, as he needs to pay it off in 20 years, then added the $300,000, and divided by 240 to get the monthly amount.
Seems I was way off lol.

hi
and for the e) one i used present value and got that he couldn't pay it off because he was about $14-15000 short but that could be wrong too
:/ yay
hmm i think that this is the z score or something, for this i got 5.2, but it might of been 5.5, i didn't know which one to use so i guessed at the funny symbol one
and for the e) one i used present value and got that he couldn't pay it off because he was about $14-15000 short but that could be wrong too
