You can't entirely say that because what if the exams were more difficult than the HSC standards and the first was indeed 80%. Would this mean the cohort is weak? Ofc not.

87, how do you know the cohort is strong?

Molecular formula of sulfur dioxide is SO2. In 1 mol SO2 there are 1 mol S and 2 moles O atoms. Now 5.45g SO2 = 5.45/64 = 0.085 moles of SO2 Therefore, No. of moles of S = 0.085x1 = 0.085 And No. of moles of oxygen = 0.085x2 = 0.17

Assume this is a table: x 0 0.1 0.2 0.3 0.4 0.5 y^2 (Values when you Sub the x into y squared) V = πh/2(1st + last + 2(middle)) V = 0.05π(arcsec^2(0)+arcsec^2(0.5)+2(arcsec^2(0.1)+arcsec^2(0.2)+arcsec^2(0.3)+arcsec^2(0.4)) This question is broken...

Unless Nadal doesn't get his form back, I can see Djokovic winning the grand slam the way he's been playing.

Do it next year 1st sem, better lecturer in charge. Theres also more resources for sem 1, also I plan to compile resources as well.

Not the school but rather your compatibility with the teacher tbh.

You can't say this because what if the cohort was not as academically smart? It does not always mean the exam was harder if students did not perform as well as the previous year. A simplified way of how scaling works is comparing performances of the different subjects. E.g. We have players...

Re: MX2 2015 Integration Marathon Shouldn't the answer be I = \frac{x^2}{5} (2 \sin \ln x - \cos \ln x) + c

Should be D. We know that GPE = - GMm/r , the greater the distance the higher the GPE as it will approach zero since we take infinite the point where GPE will equal to zero.

Atar is an aggregate of marks, not depending on one subject. Coming first in the state doesn't necessary mean you will get 99.95, evident with the UAC data where the maximum atar for a particular subject is not always 99.95.
