Yes, but I posted it on a thread to get a direct answer...Well?
2. ### Another way of answering the cirle geometry question

I sat my HSC last year but looking at this question would this be valid: let angle QBA = x therfore angle BAP = x (alternate angles in parallel lines...) Similarly, let angle BQP = y therfore angle APQ = y (alternate angles in parallel lines...) Now, angle QTA = x + y ( the...

12. ### General Thoughts: Mathematics Ext 1

looking at 60-61 couldnt get the binomial or parametrics :(

B
14. ### Past paper help please

8 (iii) use the velocity found in part (ii) i.e. v = 7/(t+4)^2 and stick that in v for dv/dt. so you get d/dt [7/(t+4)^2] and do the derivative of that equation.
15. ### Past paper help please

6) b(iii) so it's like finding an asymptote you have to see what it approaches as e^-0.05t approaches infinity so if you start sticking big numbers, 100, 1000, 1000000 etc you'll see it = 0 therefore p = 150 + 300(0) = 150 7) a(ii) need to do sum of the roots so alpha + beta and from part (i)...
16. ### Graphing f(x) and f'(x)

At the point of inflexion you can draw a tangent to that point which is horizontal hence horizontal point of inflexion
17. ### mechanics and harder 3u

yes it actually is possible

You're welcome :)

all you need to do is find the gradient of the line after the point 30000. so you would take the point (30000,1000) and (40000,3000) and do rise over run to get your gradient i.e: the rise is 2000 (3000-1000) and the run 10000 (40000-30000) therefore 2000/10000 = 0.2 or 20cents so c is the answer
