What is f(5) if f(1) = 3.2 and f(x + 1) = (f(

Step-by-step explanation:

The complete question is

What is f(5) if f(1) = 3.2 and f(x + 1) =5/2 (f(x))?

By given,

and

Now, we need to replace one be one until we get , because the given function is a sequence, so

For

Then, for

We repeat the process until we get ,

For

For

Therefore, if  and , then

4400

step-by-step explanation:

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
