1/10.
2/5 is equal to 4/10
4/10 divided by .4 is .1
so its 1/10
        
             
        
        
        
Answer: With that assumption, we have a square, whose area is given by the formula Asquare=a2, and two semicircles. The distance D is simply the square's diagonal. The area of each semicircle is given by the formula Asemicircle=π*r2/2. then you will get your answer!
 
        
             
        
        
        
Start at 4 and since it a negative go down one and over one
        
                    
             
        
        
        
F(5) = 1/4(2)^5
f(5) = 1/4 (32)
f(5) = 8
answer
A. 8
