Answer:
27°
Step-by-step explanation:
The inscribed angle is half the measure of the arc it intercepts.
∠M = 1/2 arc QR = 1/2(54°)
∠M = 27°
Answer:9
Step-by-step explanation:
Use the pythagorean theorem. 
We know both a and c, so it becomes
=
16+b^2=97=
97-16=b^2=
81=b^2=
9=b

Answer:
A
Step-by-step explanation:
The domain is the span of x-values a graph covers.
From the graph, we can see that the graph only covers the x-values less than or equal to 0. Our x-values never cross and go beyond x=0.
Therefore, our domain is all values less than or equal to 0.
As an inequality, this is:

So, our answer is A.
And we're done!
