Let $p = \frac{{\cos x + \sin y}}{{\sqrt {{w^2} - z} }}$ ,

where $x = 36^\circ ,{\text{ }}y = 18^\circ ,{\text{ }}w = 29$ and $z = 21.8$ .

Write your answer to part (b)(ii) in the form $a \times {10^k}$ , where $1 \leqslant a < 10,{\text{ }}k \in \mathbb{Z}$ .

Markscheme / solution

$3.91 \times {10^{ - 2}}$ (A1)(ft)(A1)(ft) (C2)

Note: Answer should be consistent with their answer to part (b)(ii). Award (A1)(ft) for 3.91, and (A1)(ft) for ${10^{ - 2}}$ . Follow through from part (b)(ii).
