My understanding it would be letter ( i )  because it is imaginary.  
 
        
             
        
        
        
I think it’s 3 out of 20 or 3/20 hope I could help you
        
                    
             
        
        
        
Answer: A) Exponential Function
Step-by-step explanation:
Hi, an exponential function describes best the total number of rabbits in the colony over time, because the population tends to multiply by a specific rate over time.
An exponential function can be described as a growth function, for example in the form:
A = P (1 + r) t  
Where:  
p = original population  
r = growing rate (decimal form)  
t= years  
A = population after t years  
 
        
             
        
        
        
The second question is the first choice 
        
                    
             
        
        
        
Answer:
<u>The simplest radical form of this mathematical expression is - 3√3</u>
Step-by-step explanation:
1. Let's write in a mathematical expression the information given:
-4 the square root of 12 + the square root of 75
-4 (√12) + √75
-4 (√4 * 3) + (√25 * 3)  (12 = 4 * 3 and 75 = 25 * 3)
-4 (2 √3) + 5 √3 
-8 √3 + 5√3
- 3 √3
The result is- 3 square root of 3.
