By looking at the graph, we can see that the shape is a quarter of a circle.
The area of a circle is:
So, this "quarter circle" is:
R is the radius (the diagram shows the radius is 8), so we can now find the area:
The area is 8π.
Answer:
x^2+x
--------
x-1
Step-by-step explanation:
x 1
------ ÷ --------
x-1 x+1
Copy dot flip
x x+ 1
------ * --------
x-1 1
x(x+1)
-------
x-1
x^2+x
--------
x-1
2x+ 1 = 3x - 1 ;
1 + 1 = 3x - 2x ;
2 = x ;
x = 2 ;
Then, y = 2x2 + 1 = 5 ;
