Answer:
it is B
Step-by-step explanation:
because it just is i took the test
Ah , such simple math brings the nostalgia of primary school. Good old days.
1/2 * 5/6 = 1*5 / 2*6 = 5 / 12
The number of cells of strain A follow the linear model
, where
denotes the number of cells of that strain and
is time in hours. Meanwhile, strain B follows
. The time
when both strains have the same number of cells is the intersection of these two lines, or the solution to
You have
so after 5 hours, both strains should have the same number of cells.
In order to solve this exercise, you have to know the limit that defines the constant :
With this limit in mind, we can perform the following variable change:
With this new variable, we have
Substituting these pieces one by one, we have
and this is the limit that defines e.
