In 2007, a business had sales of £10 million in a market with a size of £125 million. In 2017 the business's sales were £12.6 million and its market share was 6%. Calculate the percentage growth in the size of the market between 2007 and 2017. (4 marks)

market share 2007 = 10/125 x100 = 8%market size 2017 = 12.6/x x100 = 6% 12.6/x = 0.06 12.6 = 0.06 x (divide by 0.06) = 210 millionmarket size growth = new - old/old 210 (new) - 125 (old)/ 125 (old) x100 = 68%

The curve C has equation y = 3x^4 – 8x^3 – 3 (a) Find (i) dy/dx (ii) d^2y/dx^2 (3 marks) (b) Verify that C has a stationary point when x = 2 (2marks) (c) Determine the nature of this stationary point, giving a reason for your answer. (2)

(a) (i) differentiate C using standard technique: dy/dx = 12x^3 - 24x^2 (ii) to find the second differential differentiate the first derivative (dy/dx): d^2y/dx^2 = 36x^2 - 48x(b) In order to determine if C ...
