Hey, here's a general economics question that should be common sense but I'm just struggling for some reason: If the quantity demanded of Coke increases, price should also increase. But then, would demand then go back down to what it was originally? Or since a new equilibrium was reached, would...

Hi, I'm a first year commerce student, and I was wondering what people do for note-taking, and then studying. The way I'm going now, I'm going to print (or buying pre-printed) lecture slides, and bring these as well as a notebook to lectures. I'll write notes on the lines next to the slides...

Hi, I know the chances of finding someone who does the Bachelor of Arts and Business at UNSW here is quite low since it's a fairly new course, but I was wondering if anyone knew much about it, or knew someone who does it, or does the course themselves. The course is offered by the Arts...

Hi, I'm currently in Year 12 and post-trials, I've been looking around a little more at uni courses. I'd like to go into a Business/Commerce course. Of course, I've tried throughout the year to get as high an ATAR as I can, but realistically, I think the 96.30 for UNSW is probably going to be...

Hi, I've already got an iPhone so I just need a sim-only plan, and want to switch from Optus to Virgin since a few friends are on Virgin and it uses the Optus network anyway I think. I've heard that customer service isn't great, but what you get with the plans is good. Has anyone had...

Hi, Is Sales Revenue necessarily the same as Total Revenue? Thanks.

Hi, I'm stuck on how to integrate 2e^x/2, between 3 and 0, in exact form. Please try to show all the steps. Thanks

Hi, I haven't done exponentials for a while, but I was looking through some of my old work, and saw this: I'd figured out that y''=e^x(x+1)+e^x and then I wrote that that was equal to e^x(x+2) The rest of the question, using this result, was correct. I have no idea how I got the x+2...

Hi, I know that UNSW has a really good rep for their School of Business, so BCom at UNSW has a really good reputation. I also know that Usyd has a good reputation... kind of... (I hear that recently, it's getting by on its existing prestige...), but when I went to their uni open days, I...

Hi, I'm sure this is a very easy question, I just don't know what to do since the highest power after I find the first derivative is 3 (so how do I find what x is basically...?) The question is: For y=3x^4 + 8x^3 - 48x^2 +1, find any stationary points and determine their nature. So I...

Hi, I need a bit of help doing this question about recurring decimals. The question is: Express the following recurring decimals as fractions in their lowest terms. The one I'm having trouble with is 0.43 with the dot above the 3. For other questions, I knew what to do because all the...

Hi, Just wondering what impact outsourcing (specifically outsourcing IT) could affect the HR Cycle? I suppose for Separation it could be the potential domestic jobs that are lost.... but I'm a bit stuck for the 4 stages in the cycle :/ Thanks in advance

Hi, I need some help with this question please :) The focal chord that cuts the parabola x^2 = -6y at (6, -6) cuts the parabola again at point X. Find the co-ordinates of X. I'm clueless! Thanks!

Hi, I'm having trouble with: Find the equation of the locus of a point that moves so it's equidistant from the point (2,0) and the line x=6. Not too sure when I use distance formula for this question, and what to do with the x=6. Thanks!

Hi, The question I'm not sure how to work out is: Find the equation of the parabola with co-ordinates of vertex (0,0), and equation of axis x=0, passing through (-1, 7). The answer is x^2=1/7y I think I'd use the x^2=4ay general equation, but not sure how to work out what a is... Thanks!

Hi, The question I'm stuck on is: Find the equation of the locus of a point so it is equidistant from P(2, -3) and the line y=7. If it was between 2 points, I could've done: distance formula of Point A = distance formula of Point B and solved it from there, but I'm not sure what to do when...

Hi, I need to prove that x^2+2x+y^2-4y-4=0 has the tangent 3x+4y+10=0. How I've done previous questions like this is through simultaneous equations, then finding the discriminant, and if the discriminant=0, that means it's got one root and hence that's the tangent. I just keep going...

Hi, When you differentiate (5x+3)^3, which then equals 3(5x+3)^2, how do you get to 15(5x+3)^2? Is it because you multiply it by the derivative of (5x+3), which is 5? But why do you do that? Because I thought you only did that if there was only 1 function of x... Sorry, this is a really...

Hi, I really do need to study for Calculus a little more... How do I find the derivative of 2 over the square root of x? The answer is negative one over the square root of x^3. Thank you!

Hi, I'm pretty sure this is actually quite a simple question, but I just don't know how to answer it: "A function is defined by f(x)=x^2-4x+5. What are the coordinates of the point on y=f(x) which has a gradient of 2?" Thanks.
