1st place

"I got the question right if you consider D to be close to the origin, but strictly speaking the letters should be in alphabetical order around the paralellogram." Yea, there are two cases if the question didn't have the word "respectively"

You clearly have no clue on this IT shit + they probably only spend their free free time fixing this site

I'm the complete opposite. I never have homework...though I don't always do it when I do have homework I spend 2-4hrs studying

Do they? Well it is 2unit..

This question can be done easily if you're good at manipulating stuff. I wonder how many people will say this is 4unit or something.

I dont think I have one

Yea...but I think understanding is more on knowing what's actually going on mathematically

Not really...but that's what I think. I dunno how you guys define "understanding"

Hmmm. I think Trebla > Fitzpatrick because Trebla is most correct. Answers can be wrong you know

ii) 100,000 - 154000(1.1^n -1) =-54000 x 1.1^n + 154000 154000 - 54000 x 1.1^n iii) 11th yr. 1693283.53 iv) 7.25... so 7th? or is it 8. I cbf checking Not sure if I got em correct

This is good but this technique is a bit advanced for 2unit. All he's done was translate the graph down by 1 space and integrated it along the x axis

Drongoski and Trebla got part 1 I'll finish off my part 2 y1 = a Then x1 = +/-2a (sub a back into x^2=4a(y) Normal: y= +/- 1 (x+/-2a) + a Solve simulatenously with x^2 = 4ay You will get +/- 6a Then sub this back in and you'll get y= 9a

Wow. Fitzpatrick also forgot the nomal at the origin. Lol

Happens to my questions all the time

Oh ok. Didn't notice that New question: A finance company has agreed to pay a retired couple a pension of $19200/yr for the next 20 yrs, indexed to inflation that is 3.5% per annum. How much would have the coupe been paid over 20 years? In return, the couple pay an upfront fee which the...

It's a harder 2 unit question Definitely not induction. That teacher who wrote the exam clearly didn't read the question
