Answer:
x < –4 or x ≥ 3
Step-by-step explanation:
8 hours
We have that;
B = number of bacterial cells, B, in a container after t hours
t = time taken in hours
The function is;
B=25x2t
Where B = 400 bacterial cells
400 = 25x2t
t = 400/25x2
t = 8 hours
x=5/4, 3/10
the answer is 1/360.
cross multiplication and u get the answer
