Answer:
0.3
Step-by-step explanation:
To find p we require the cube root of 0.027, that is
p³ = 0.027, then
p = =
=
= 0.3
The general equation for exponential growth can be written as:
where r is the growth rate.
Plugging in the given values, we get:
Therefore
giving
![1+r= \sqrt[3]{1.1} =1.0323](https://tex.z-dn.net/?f=1%2Br%3D%20%5Csqrt%5B3%5D%7B1.1%7D%20%3D1.0323)

where r is the growth rate.
Plugging in the given values, we get:
Therefore
giving
The predicted number of bacteria after 17 hours is given by:
