Answer:
1
Step-by-step explanation:
The coefficient is the number in front of the variable.  Since there is not a number written, there is an implied 1
x+4
1x+4
The coefficient is 1
 
        
             
        
        
        
Total points : 46
15% of 40 is 6
40 + 6 = 46
To double check:
46/40 = 1.15 = 115%
        
             
        
        
        
Answer:
Reminder that is this form  a(b)^x  where  a > 0
When   b > 0  but < 1 that is a decay function 
When   b > 1 than its a growth function 
Step-by-step explanation:
So following this you can figure out the answer 
g(x)=0.3(x)      
this is neither since there is no exponent (linear)
H=72(56)^t    
this is growth since b  = 56
A=(43)^t        
this is growth since b  = 43 ("a" is understood as "1")
H=5.9(0.82)^t      
this is decay since b =  0.82
y=0.8(3.6)^t      
this is growth since b = 3.6
f(t)=0.72(15)^t    
this is growth since b  = 14  
 A=49(8)^t      
this is growth since b  = 8
