Answer:
2
Step-by-step explanation:
-4x -y + 4
=-4*-1/4 -3 + 4
=1+1
=2
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.
Step-by-step explanation:
306 cause 2448divided by 8
3/6 is the answer
3/6is 0.50 and 2/5 is 0.40
Just divide them
