Answer:
1/4th
Step-by-step explanation:
This comes from knowing the unit circle in both radians and degrees. However, you could also calculate it from knowing that 360 degrees is 2 radians. What you'll find is that
 radians. What you'll find is that  radians is 90 degrees, or 1/4th of the circle. This means that an arc measuring
 radians is 90 degrees, or 1/4th of the circle. This means that an arc measuring  radians will be 1/4th of the entire circumference.
 radians will be 1/4th of the entire circumference. 
I hope this helps!
 
        
             
        
        
        
Answer:
D = sqrt[ (2-4)^2 + (7- (-1))^2] = ~8.2
Step-by-step explanation:
D = sqrt[ (Fx-Gx)^2 + (Fy- Gy)^2] 
 
        
             
        
        
        
The (x + 4) tells you that the function is moving 4 units to the left.
the answer would be letter C
