Answer:
The first graph represents y<2x-3
For this use some values for x e.g
X= 2 2(2)-3=y=1
So when x is 2 y is 1 so search for the graph that crosses the coordinate (2,1)
Which is graph A
49t^8 is the correct answer
First, find the area of the larger sector (the 360-130=230 degree sector), then add the area of the triangle.
area of the larger sector:(230/360)π*11.1²≈247.17
area of the triangle when two sides and the angle between the two sides are given: (absinФ)/2. In this case, a=11.1, b=11.1, Ф=130
(11.1*11.1*sin130)/2≈47.19
the total area is 247.17+47.19≈294.4
