4MA0 Higher June 2017 Paper 3R Q1
1 \(a = 6\qquad b = 2.84\qquad c = \sqrt{5}\)
Work out the value of \(\dfrac{a - b}{c^2}\)
(2)
| Scheme | Marks |
|---|---|
| \(\dfrac{6 - 2.84}{(\sqrt{5})^2}\) or \(\dfrac{6 - 2.84}{5}\) oe | M1 |
| 0.632 | A1 |
| (2) | |
| (2 marks) |
Notes
M1: or for 0.63
NB: Accept 2.23(6…) in place of \(\sqrt{5}\)
A1: for 0.632 or \(\dfrac{79}{125}\)
SC : B1 for an answer of 1.41(31…)
