Step-by-step explanation:
The distance between the San Diego, California, to Bar Harbor, Maine is 3302 miles.
Now, the Garcia family is driving from San Diego, California, to Bar Harbor, Maine. The distance that they have traveled is 2,045 miles in 5 days.

Answer:
There will be 50 bacteria remaining after 28 minutes.
Step-by-step explanation:
The exponential decay equation is
N= Number of bacteria after t minutes.
= Initial number of bacteria when t=0.
r= Rate of decay per minute
t= time is in minute.
The sample begins with 500 bacteria and after 11 minutes there are 200 bacteria.
N=200
= 500
t=11 minutes
r=?
Taking ln both sides
To find the time when there will be 50 bacteria remaining, we plug N=50, = 500 and
in exponential decay equation.
Taking ln both sides
minutes
There will be 50 bacteria remaining after 28 minutes.
