I would say both B and F would be polynomials.
Horizontal line means that y is a constant. This means the line is y = -6.
Answer:
The radius of the circle is 24 inches.
Step-by-step explanation:
Central angle in a sector is 90 degrees
Area of a sector is 
The area of sector is given by the formula as follows :

r is the radius of circle

So, the radius of the circle is 24 inches.
(3,0) and (0,9)
Slope= (9-0)/(0-3)= -3
Line equals Y= -3x+9
The area is 24 square inches. So its dimensions in inches
must be factor-pairs of 24 .
Those are
1 x 24
2 x 12
3 x 8
or
4 x 6 .
