K, so am assuming of th next day
from 7pm to 12 midnight is 5 hours
from 12 midnight so 3am is 3 hours
3+5=8
8 hours total
checked double the amoutn last time
he spent 16 hours last time?
Here are all of the answers for the problems showed...
10- 8.72=8.720
13- 2.573<2.753
16- 2.97, 2.714, 2.09, 2.007
Answer:
5,120 bacterias
Step-by-step explanation:
Given the amount of bacteria after x hours modelled by the equation:
f(x) = 20(2)^x/12
Note that x is in hours not days
To calculate the number of bacteria that will be contained within the culture after 4 days, we will first convert 4days into hours since x is in hours.
24hours = 1day
xhours = 4days
x = 24×4
x = 96hours
Substituting x = 96 into the equation
f(96) = 20(2)^96/12
f(96) = 20(2)^8
f(96) = 20×2^8
f(96) = 20×256
f(96) = 5,120
The number of bacteria that will be contained after 4days is 5,120bacterias
