Aparticular bacteria population on an athlete's foot doubles every 3 days. determine an expression for the number of bacteria n after t days, given the initial amount is 40 bacteria.

Step-by-step explanation:

The exponential growth formula is:

NOTE: This problem is asking to use N instead of A and T instead of t

Step 1: find the rate  

Step 2: input the rate to find N

Step-by-step explanation:

The growth of bacteria is an exponential function. The equation has the general form

Using the variables N and T, we can rewrite the equation as

We have two conditions:

(1) There are 40 bacteria at T = 0

(2) There are 80 bacteria at T = 3.

Insert these values into the equation.

dunno

step-by-step explanation:

to rewrite a literal equation you may need to divide by a number, or by a variable.
