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...

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.
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)...
