The vertex is (3,0).
The 3 inside the abs val bar tells you the x value of the vertex is 3. No number outside the abs value bar is a +0 which is the y value of the vertex.
Now, we know that 90°< θ <180°, that simply means the angle θ is in the II quadrant, where sine is positive and cosine is negative.

7:45 -1 hour=6:45
The concert started at 6:45
7:45+2 hours=9:45
The concert will be over at 9:45
The time outside the theater is
5:30a.m. or 5:30p.m.
It's most likely 5:30p.m. as 5:30a.m. is really early in the morning.
This is an EXPONENT.
To do this all we need to do is multiply the base by itself how many times the power says.
(-6)² = (-6) × (-6) = 36
Recall that any negative number times another negative number is positive so that is why this would be positive.
So, (-6)² = 36
