Answer:
354.
Step-by-step explanation:
Exponential growth:
380 = 200e^(k*9) where k is a constant to be found.
e^9k = 380/200 = 19/10
ln e^9k = ln 1.9
9k = ln 1.9
k = ln 1.9 / 9
k = 0.071
After 8 hours:
Number of bacteria =
200*e^(8*0.071)
= 354.

Answer: 7.1
Step-by-step explanation:
Exponential functions: y=ab^x
A = starting value
R= rate ex: 3% = .03
B= 1 + r
Then write your exponential function
