6 or answer 4 k
B1 for or − − 10 k 3
6(b)(i)[1]
(–4, –1) [1]
6(b)(ii)[2]
7.21 or 7.211… [2]
M1 for (–6)2 + 42
6(c)(i)[6]
2c – a [1]
c – a [1]
1 5 (a + 8c) final answer [2]
M1 for [ AP =] 4 5 × their(2c – a) = ] 1 5 × – their (2c – a) or [ BP or for a correct vector route using the lines on the diagram 4 5 (– a + c) final answer [2]
M1 for [QP = ] – 4 5 c + 4 5 × their(2c – a) or for a correct vector route
6(c)(ii)[2]
[QP is] parallel [to CB ] QP = 4 5 CB oe [2]
Dep both statements consistent with their (c)(i)(b) and their (c)(i)(d) and both vectors in terms of a and c
