Answer:
the warmest is wilmington
Step-by-step explanation:
it's 0 degrees and the other ones are lower so i mean it's common sense positives are greater than negatives
Answer:
First, let's recall some usefull information:
- cot(x) = 1/tg(x) = cos(x)/sin(x)
- tan(x) = sin(x)/cos(x)
We also know that:
- cos(x - pi/2) = sin(x)
- sin(x - pi/2) = -cos(x)
Now we can use those relationships and get:
cot(x - pi/2) = cos(x - pi/2)/sin(x -pi/2) = sin(x)/-cos(x) = -tan(x)
So we have verified the identity, and explained step by step why the identity is true.
Looks like it should be D since they spent 0.08 on tickets and get 1.92. Then shirts are $55 so we subtract this from the profit.
