Right angle is the right answer
This formula solve by discriminant (D=b^2-4ac)
Answer:

Step-by-step explanation:
Given that,
The radius of circle, r = 50 feet
The central angle, 
We need to find the area of the sector of a circle. The formula for the area of sector is given by :

So, the area f the sector of the circle is
.
Yes, (3,-1) is a solution to the graphed system of inequalities.
<h3>What are system of inequalities?</h3>
When mathematical expressions are compared, with non-strict equality, then such mathematical statements are called mathematical inequalties.
A collection of inequalities for which we consider a common solution for all inequalities is called a system of inequalities.
As we can see in the graph that the two lines are interest in the second quadrant at point such as(x, -y).
So, the point will be a solution also because it lies in the shaded region.
Therefore, Yes, (3,-1) is a solution to the graphed system of inequalities.

Answer:
He drove 18,075.48 miles
Step-by-step explanation:
Since he was charged $17 to begin with, we subtract 17 by $211.36 and get 194.63, then we multiply our answer by 93 to get the exact amount of miles he drove. We then get the product of 18,075.48 miles.
