Step-by-step explanation:
<u>Step 1: Define</u>
x/5 - 1 = 10
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 1 to both sides: x/5 = 11
- Multiply 5 on both sides: x = 55
Answer:
Part 1) The exponential function is 
Part 2) 
Step-by-step explanation:
Part 1) Write an exponential function
we know that
The exponential growth function is given by the formula

where
y is the population
x is the number of years
a is the initial population
r is the rate of change
we have

substitute


Part 2) How much will the population be after 16 years?
For x=16 years
substitute the value of x in the exponential function
