Answer:
The net gain or profit is $600
Step-by-step explanation:
Firstly, we should know the losses of the customer which were:
9 when the customer bought 1 MCS Oct 50
1 when the customer bought back 1 MCS Jul 50
Therefore the total losses were 10.
And the gains were:
4 when the customer sold 1 MCS Jul 50
12 when the customer sold 1 MCS Oct 50
Therefore the total gains were 16.
Therefore (16 - 10)×100 = $600
Therefore the net gain or profit is $600
Answer:
k = 0.5
Step-by-step explanation:
Substitue y = 12, x = 24 into y = kx.
12 = k × 24
24k = 12
k = 12 ÷ 24
k = 0.5 (final answer)

Answer:
n = π/6, π/4, 3π/4, 5π/6
Step-by-step explanation:
sin(3n) − sin n = cos(2n)
Use double and triple angle formulas:
(3 sin n − 4 sin³ n) − sin n = 1 − 2 sin² n
2 sin n − 4 sin³ n = 1 − 2 sin² n
4 sin³ n − 2 sin² n − 2 sin n + 1 = 0
Factor by grouping:
2 sin² n (2 sin n − 1) − (2 sin n − 1) = 0
(2 sin² n − 1) (2 sin n − 1) = 0
Solve:
2 sin² n − 1 = 0
2 sin² n = 1
sin² n = 1/2
sin n = √2/2
n = π/4, 3π/4
2 sin n − 1 = 0
2 sin n = 1
sin n = 1/2
n = π/6, 5π/6
