Step-by-step explanation:
In the figure below, segment CD is parallel to segment EF, DE is a transversal, then angles DIH and HGI are congruent as alternate interior angles when two parallel lines are cut by a transversal.
Consider triangles DIH and EGH. In these triangles,
as alternate interior angles;
as vertical angles;
because point H bisects segment DE (given).
Thus,
by AAS postulate
ANSWER
Approximately after 15 minutes.
EXPLANATION
The growth rate of the first bacteria is
The growth rate of the first bacteria :
To find the time that, there will be an equal number of bacteria, we equate the two equation;
We solve for t to get,
Or
We discard the negative value.
This implies that,
