By a ratio of 2 to 1, I declare the matter resolved.

Carrotsticks has made only 2 posts this year, the last one 6 months ago. Don't get your hopes up.

1 out of 3 at best if you use that formula.

For (a), see my response to your same question in the Ext 2 thread.

For a start, this is 2 unit, not 4. 97% of the light gets through the first sheet. 97% of THAT transmitted light gets through the second sheet. So 0.97^2 of the light incident on the first sheet gets through the two sheets. Following this through, if there are n sheets then the fraction of...

I think he would prefer to get serviced by females.

Your HSC is in 2019. Call it 'procrastinating' in two years time. Right now it is called 'enjoying your holidays'.

Alternatively, since the Cartesian equation is given, just sub in the parametric equations and expand.

If their aim is to choose dux based on assessments, then they have chosen the correct dux.

Assuming you've learned the h/3 version of Simpson's rule: h=(2-1)/4 = 1/4 So the x-values used are 1, 1.25, 1.5, 1.75, 2 So the y-values used are 1, 4/5, 2/3, 4/7, 1/2 So the approximate value of the integral is: (1/4)/3 [1 + 1/2 + 4 (4/5 + 4/7) + 2(2/3) ]

Stage 5.3 syllabus: Determine the inverse functions for a variety of functions and recognise their graphs as reflections of the graphs of the functions in the line y=x Describe conditions for a function to have an inverse function Recognise and describe the restrictions that need to be...

You don't need so much combinatorics. If you assign the positions of letters in the word numbers 1 to 7, and you don't care about the order of N and T, the number of ways of choosing the order of those letters is 7C2 = 21. The number of ways of choosing these letters with 5 letters...

I agree that the exam system is not ideal, and creates a production line mentality. That is why they are bringing alternative assessments into the new syllabus.

Re: HSC 2016 MX2 Combinatorics Marathon As an aside, this question won't prove that you have found the minimal solution, merely that the formula works for your method. There is an interesting graph which shows that the method is the optimal solution by noting that the shortest path between...

The equation of the normal is cubic in t. Hence it has up to three real roots (dependent on the value of the point [x,y] you substitute into the normal equation), each root (value of t) corresponding to a point on the parabola.

How does one tell sarcasm in a toneless internet post that is devoid of the kind of language which tips one off to sarcasm?

Actually the vaccines have been proven NOT to cause autism. I think you are reading the same type of article you suggested Drsoccerball was reading. Half a million children were tested in Denmark, and the study found that unvaccinated and vaccinated children were equally likely to acquire...

Found him.
