Read a little interesting statistic. In the last 2 decades the number of enrolments in Business Studies has increased by up almost 40% from 2 decades ago. 1996: 12,522 2006: 16,029 2016: 17,557

Nice so I'm taking it you would pick D?

'All rhombuses are similar' I got this wrong admittedly. My only guess is even if they have the same (proportions ) for the sides, you can get instances where the corresponding angles are different. I've drawn a diagram below: \angle \ ABD $ could be different to $ \angle EFH

This was the 1st question in last years HSC exam (2016) Q1. A red leather lounge was purchased from Lounge Ltd. After only 2 weeks of use, the legs of the couch fell off. What is the law that enforces the warranty in this situation? (A) Corporations Act 2001 (Cth) (B) Fair Trading Act 1997...

Decided to open up a Business Studies Marathon for any current or former HSC students to discuss any content related to this subject. I've done some accounting and finance units before but hardly remember any of it as I did it a long time ago. Thought it would be good to brush up a few...

Hence, why your correct when the question came 'All rectangles are similar'-----> FALSE (in the textbook) Again, before today I would have said TRUE. I do understand now that you have to look at the aspect ratio (long sides v short sides of both shapes)

Interesting little fact from that wikipedia link: "For example, all circles are similar to each other, all squares are similar to each other, and all equilateral triangles are similar to each other. On the other hand, ellipses are not all similar to each other, rectangles are not all similar to...

Now everybody on the forum can have a laugh at me now ! And the answer was True

I came across this question in the Cambridge year 10 maths book and it got me thinking this early morning. This chapter was part of the Geometrical figures and circle geometry. (I haven't looked at the answer yet) Q. Are these statements true or false? " All circles are similar" I think...

What other Circle Geometry programs are there ? Or ones that the NSW curriculum encourage students to use? Geogebra is one. Efofex is one that is used in WA (but I never touched much on that subject in the past), so rarely touched it Are there maybe other ones that are used?

Just a bit of a left field question, do the high schools in NSW teach the students to spend much time on drawing out Circles , in circle geometry? Personally, think it would be a great learning tool in learning Geogebra or the equivalent circle geometry software and enhancing that learning at...

Re: International Baccalaureate Marathon $ Points A,B and C have position vectors A $ \begin{pmatrix} 1\\-19\\5 \end{pmatrix}, B \ \begin{pmatrix} 3.2\\3.6\\2 \end{pmatrix} , C \ \begin{pmatrix} -6\\-15\\7 \end{pmatrix} $ The respective magnitudes: $ |\overrightarrow{AB}|=\sqrt{524.6} ...

Also no disrespect to Allens- I have never heard of them (but based on what I have read I'm not sure if it's a company that I would want to work for-they do seem a tad elitist) but do they have any links with UWA law by any chance? Not sure but I didn't have too many friends at UWA law at my...

I wrote this on the Whirlpool forum and I'll post it here on the BoredofStudies. I have no jealousy or animosity towards people that achieve high ATAR's but the recruitment process factoring into account ATAR is a bit of a joke if you tell me. I must admit I had a fairly average ATAR coming...

Re: International Baccalaureate Marathon I meant vector AB, should have been -2-k.

Re: International Baccalaureate Marathon Not that much. I just went to the gym for about an 1.5 hour, also did a bit of driving and I went out to the library for a bit of fresh air.

Re: International Baccalaureate Marathon Was going through worked example from Cambridge tonight and there was a mistake in the working out for part (c), vector BC should be -2-k. Small mistake but its important that I point it out to all IBers in 2017:

Re: International Baccalaureate Marathon ^^ Building on from what I have said, if the vectors are meeting in opposite directions, I need to reverse one of them so that either they meet together or leaving the same point at the one time.

Re: International Baccalaureate Marathon \overrightarrow{BA}= \begin{pmatrix} -1\\2\\2 \end{pmatrix} cos \ \theta= \frac{\overrightarrow{BA} . \overrightarrow{BC}}{|\overrightarrow{BA}| |\overrightarrow{BC}|}=\frac{1}{\sqrt{14}} \theta =74.5 ^\circ That's the standard 1st year...

Re: International Baccalaureate Marathon I came across this question today Question 3(i): Here was my attempted working out: \overrightarrow{AB}= \begin{pmatrix} 1\\-2\\-2 \end{pmatrix} \ \overrightarrow{AC}= \begin{pmatrix} 4\\0\\-1 \end{pmatrix} \ \overrightarrow{BC}= \begin{pmatrix}...
