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

Yes. One input results in one output. the last choice is correct.
every x value will product only one y value.
Answer:
2 1/3
Step-by-step explanation:
She will need 2/3 of 3 1/2:
(2/3)(3 1/2) = (2/3)(3) +(2/3)(1/2) = 2 + 1/3
Amanda will need 2 1/3 cups of milk.
3x^2-18+5=47
3x^2 = 60
x^2 = 20
x = 4.472 , x = - 4.472
