Answer:
5<em>i</em>
Step-by-step explanation:
- =  
- =  
- =  * 5 * 5
Rule:  = <em>i</em>
 = <em>i</em>
So you get <em>i  </em>* 5<em> </em>=<em> </em>5<em>i</em>
 
        
             
        
        
        
Answer:
Diverge
Step-by-step explanation:
(a)
1st year: 
2nd year: 
3rd year: 
4th year: 
5th year: 
(b) The sequence is divergent, because if we take the derivative of the function with respect to n year:

This is a positive, meaning the slope of the function is positive. If we take the second derivative using product rule

This is also positive when n > 0. Therefore, the slope is positive and increasing. This means the sequence diverges.

Combine like terms
-6x² + (-x²) = -6x² - x² = -7x²
-7x² + 15x + 4 is your answer
hope this helps
