Answer:
325 minutes
Step-by-step explanation:
We can use a ratio to solve
25 minutes x minutes
------------------ = ---------------
1 burger 13 burgers
Using cross products
25*13 = 1x
325 = x
325 minutes

Answer:
C. x² -4x +1
Step-by-step explanation:
The synthetic division is shown below. The quotient corresponds to answer choice C.
First one is 32.2 and the second one is -32.34
This is the concept of exponential growth;
the formula for obtaining the number of bacteria at time t in future is:
f(t)=ae^(kt)
where;
f(t)=population in future
a=initial population
k=constant of proportionality.
suppose the initial population was x, when the population doubles it will be 2x at a future time t.
k=0.027
thus substituting the above in our formula we get:
2x=xe^(0.027t)
solving for t we get:
2=e^(0.027t)
introducing the log function we get:
ln2=0.027t
thus;
t=(ln2)/0.027
=25.67
therefore;
t=25.67 hours
