A certain culture of the bacterium Rhodobacter sphaeroides initially has 45 bacteria and is observed to double every 5 hours. (a) Find an exponential model n(t)

The exponential model n(t) is

Step-by-step explanation:

Exponential model of population growth:

An exponential model for population growth has the following model:

In which n(0) is the initial value and r is the growth rate, as a decimal.

Observed to double every 5 hours.

This means that

We use this to find 1 + r. So

So

Initially has 45 bacteria

This means that . So

The exponential model n(t) is

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.

but there’s no any figure there!
