Answer:
a). 8100 bacteria
b). 519 bacteria
c). Infinite
Step-by-step explanation:
Population growth of a bacteria is given by the exponential function,
f(x) = 
Where f(x) = Population after time 't'
= Initial population
r = Growth rate
t = Duration after t hours
If "100 bacteria gets tripled every hour"
300 = 
3 = 1 + 
r = 100×(3 - 1)
r = 200
So the function is, f(x) = 
a). Population after 4 hours,
f(4) = 
= 8100 bacteria
b). Population after 90 minutes Or 1.5 hours
f(1.5) = 
= 519.61
≈ 519 bacteria
c). Population after 72 hours,
f(72) = 
= Infinite
Answer:
-2
Step-by-step explanation:
When you divide negative 6 by 3, it stays a negative. So, it's like dividing 6 by three then putting a negative sign on it.
Thank you for posting your question here. <span>The first and fourth quadrants will be used. Since x is time you only need positive x values. Since y is temperature you'll need both positive and negative numbers on the y-axis. I hope it helps. </span>
A) 1 and 2
That is the correct answer
