Pi/3 is equivalent to 60 degrees, as 2pi is equal to 360 degrees. cos(60) in a triangle yields 1/2, and sin(60) yields (3^(1/2))/2. Thus, -pi/3, or -60 degrees would be a fourth quadrant point on the unit circle and these values would be negative as well, at cos(-pi/3)=-1/2 and sin(-pi/3)=-(3^(1/2))/2
Answer:

Step-by-step explanation:
We want to simplify;

We expand the bracket to obtain;

We now group the like terms to obtain;

We now simplify to get;

The correct answer is C
electricity comes from electrons, does morality come from morons? No, you're thinking of mormality. That is true, especially in the US. ... This means that the stupider a group is overall, the less moral they are expected to beon:
Answer:
h < 2
Step-by-step explanation:
Step 1: Distribute
10h + 40 < 60
Step 2: Subtract 40 on both sides
10h < 20
Step 3: Divide both sides by 10
h < 2
