Answer:
x>5
Step-by-step explanation:
30 < 6x
Divide both sides by 6,
5 < x => x>5
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:
30in I know that because I just did this .this is EASY!
The points have the same x-coordinate, so they lie on a horizontal line. The distance between them is the difference between their y-coordinates.

The distance between the two points is 1.3.
B is because any form of y=Mx +c is proportional
