Answer:
decrease by 35%
Step-by-step explanation:
0.65 is only 65% of a whole number, so it decreases the original number by 35%

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
Answer:
k=95
i don't really know how to explain it! Just try matching the questions up yourself :)
multiply -.4*95 to see if the result is -38
I'm 99.99999999999% percent sure it is right
