Answer:
    12.94%
Step-by-step explanation:
r = 100(1/2)^(d/5) = 100((1/2)^(1/5))^d ≈ 100(.87055)^d
The daily decrease is 1 - 0.87055 = 0.12944 ≈ 12.94%
 
        
             
        
        
        
Answer:
y= 7x-73
Step-by-step explanation:
the equation form is y=mx+c where m is the slope and c a constant
m= (25-(-10))/14-9 = 35/5 = 7
so y= 7x+c 
replace x and y by 14 and 25 respectively 
25 = 7*14+c 
c= 25-7*14 
c = -73 
so y= 7x-73
