R=6 & s=1/4 
Just plug that in to the equation. 
6+1/4 +14(1/4) 
6.25 +3.5 
9.75 or 39/4
        
                    
             
        
        
        
It's a nonlinear because the x and y values are not increasing at the same ratio each time. This would be an example of a linear function:
x l 1 2 3  4   5   6
y l 3 6 9 12 15 18
As x increases by 1, y increases by a multiple of 3
        
                    
             
        
        
        
Solution:
12 hours = 12 * 60 minutes = 720 minutes
Number of days lose = 
So, 17th May + 120 days = 14th Sep.
 
        
             
        
        
        
Answer: 463.96 mm² or 46.4 cm²
Step-by-step explanation:
Quarters are circular in shape so the surface area of one side will be the area of a circle. 
Area of a circle = π * r²
Radius = Diameter / 2
= 24.3 / 2
= 12.15 mm
Area = 22/7 * 12.15²
= 463.96 mm²
 
        
             
        
        
        
digit #1 - 9 numbers (1-9)
digit #2 = 9 numbers (0-9 minus the first digit)
digit #3 = 8 numbers ( 0-9 minus the first 2 digits)
9*9*8 = 648 combinations
