- 1Perpendicular Lines and the equation of a tangent3 marks
The point (20, 21) lies on the circle x^2 + y^2 = 841. Work out the gradient of the tangent to the circle at that point.
- 2Conditional Probability3 marks
A bag holds 5 red, 3 blue and 3 green counters. Two are taken without replacement. Given neither is green, what is the probability both are red?
- 3Histograms3 marks
A histogram has two bars: one 10 units wide with frequency density 0.4, one 20 units wide with density 3.5. How many values in total?
- 4Surds3 marks
Simplify sqrt(20) + sqrt(125), giving your answer in the form a sqrt(b).
- 5Completing the Square3 marks
Work out the coordinates of the turning point of y = x^2 - 2x + 7.
