Answer:
Step-by-step explanation:
A = P (1 + i)³
A = final amount
P = principal
i = interest
3 = 3 years
A = $600 (1 + 0.08)³
A = $600 (1.26)
A = $756
Answer:
a=8b
Step-by-step explanation:
To do this we just need to isolate a
so we can multiply the equation by b
then we will get
a=8b
Answer:
3 strain would still alive after 48 hours
Step-by-step explanation:
Initial population of virus = 40000 grams
A certain virus is dying off at a rate of 18% per hour.
We are supposed to find how much of the strain would still be alive after 48 hours
Formula : 
=Initial population
N(t)= Population after t hours
r = rate of decrease = 18% = 0.18
t = time = 48 hours
So,the strain would still be alive after 48 hours=
Hence 3 strain would still alive after 48 hours
I’m pretty sure it’s Number 3. Hope I’m Right.
