Answer: f(9) = 20.2 .
_______________________________
Explanation:
_______________________________
f(9) = pe^(r*t) = 9* e^(0.09 * 9) ;
_______________________________
Note: 0.09 *9 = 0.81 .
______________________________
→ f(9) = pe^(r*t) = 9* e^0.81 ) ;
_______________________________
Note: e^(0.81) = 2.24790798668.
f(9) = 9 * 2.24790798668 ;
= 20.2311718801 ;
→ Round to the nearest tenth:
f(9) = 20.2 .
