I hate APEX!
A is right since the graph would start at 2 and go towards negative infinity
D is right both graphs approach +2 as thier highest values
        
             
        
        
        
The area of a sector is 339.336 cm²
The area of a sector is defined to be as the region of space bounded by a boundary from the center of the circle.
It can be determined by using the formula:

Given that;
- Radius r = 18 cm
- Angle θ =  120° 
Then. the area of the sector can be calculated as:


A = 339.336 cm²

The distance formula is:  d  =  sqrt( (x2 - x1)2 + (y2 - y1)2 )
 
For this problem, let (-5, -4) be the "first" point, so  x1 = -5  and  y2 = -4
                      and let (-6, 4) be the "second" point, so  x2 = -6  and  y2 = 4.
 
Then:  d  =  sqrt( (-6 - -5)2 + (4 - -4)2 )  =  sqrt( (-1)2 + (8)2 )  =  sqrt( 1 + 64 )  =  sqrt( 65)
 
The distance formula is just the Pythagorean Theorem applied to an x-y graph.
 
You would get the same final answer if you let (-5, -4) be the second point and (-6, 4) be the first point.
