The diagram below, not drawn to scale shows part of the curve y = x² + 5 and the line y = 8.2x. The line intersects the
curve at points C and D. Lines AC and BD are parallel to the y-axis.

(a) Determine the coordinates of C and D.
(b) Use integration to calculate the area bounded by the curve and the x-axis between the points C and D.
(c) Calculate the area enclosed by the lines CD, CA, BD and the x-axis.
(d) Hence determine the area of the shaded region.

  (a) P, Q and R are three quantities such that P varies directly as the square of Q and inversely as the square root of R.
  (i) Given that P = 12 when Q = 24 and R = 36, find P when Q = 27 and R = 121.
  (ii) If Q increases by 10% and R decreases by 25%, find the percentage increase in P.
  (b) If Q is inversely proportional to the square root of P and P = 4 when Q = 3.
  Calculate the value of P when Q = 8.
