Answer:
The most straightforward way to obtain the expression for cos(2x) is by using the "cosine of the sum" formula: cos(x + y) = cosx*cosy - sinx*siny. cos(2x) = cos² (x) - (1 - cos²(x)) = 2cos²(x) - 1. = 2cos²(x) - 1.

Answer:
32000 tonnes
Step-by-step explanation:
Given there was a 20% reduction last year from a total of 40000 tonnes .
20% /100% x 40000
