Answer: Hello there!
We know that the culture has 2000 bacteria initially (at t = 0 min), and it doubles when t = 40min, again at t = 80 min, and so on
And the rate of grouth is proportional to the population, then we can obtain an expression of the form:
P(t) = 2000*k(t) where k(t) is the factor that defines the growth of the population:
we know that:
p(0) = 2000*k(0) = 2000
p(40) = 2000*k(40) = 2000*2 = 4000
p(80) = 2000*k(80) = 2000*2*2 = 8000
etc
then we can see that k(t) = 2^(t/40)
where k(0) = 1, k(40) = 2, k(80) = 2*2, etc
then the function that models the population of the culture is:
p(t) = 2000*2^(t/40)
where t is in minutes.
The actual weight of the package is 42 pounds.
Step-by-step explanation:
Given weight of package = 28 pounds
Let,
x be the actual weight.
According to given statement;
The actual weight is multiplied by 2/3
Therefore;
Multiplying both sides by 3/2
The actual weight of the package is 42 pounds.

Answer:
0.004129
Step-by-step explanation:
I'm not sure if you meant this by usual form, if it isn't please let me know and I will redo it for you :)
First,
10^-3 can be simplified to 0.001
Second,
4.129 multiplied by 0.001 is 0.004129.
Hope this helps!!
