I’m not so sure I fully understand the question. But I would say the rate is 1.
I say this because the line on your graph is a y=mx+b equation.
For every unit it moves over on the X axis it moves the same unit on the Y axis.
I hope this helps.
Answer:
21870 km^2
Step-by-step explanation:
Area of sector=1/2r^2(theta)
Where r=18 km and theta=135
Area of sector=1/2(18)^2(135)
=1/2(324)(135)
=1/2(43740)
=21870 km^2
If you can't see the picture the answer is: (y+4)(y+2).
Hope this helps, and May the Force Be With You!
