Answer:
8 hours
Step-by-step explanation:
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

Answer:
x = 48
Step-by-step explanation:
log〖 (2x+4)〗=2
Raise each side to the base of 10
10 ^log〖 (2x+4)〗=10^2
The 10 ^log cancels
2x+4 = 100
Subtract 4 from each side
2x+4-4 = 100-4
2x = 96
Divide by 2
2x/2 = 96/2
x =48
