The bacteria in a certain culture triples every 7.7 hours. the culture has 6,500 bacteria at the start. how many bacteria will the culture contain after 4 hours?

11505 bacteria

Step-by-step explanation:

Given :

The bacteria in a certain culture triples every 7.7 hours. The culture has 6,500 bacteria at the start .

As per the  exponential growth , we have

Here ,

is starting number of bacteria

R is rate at which number of bacteria increases

T is time elapsed

P is one period of rate

On putting these values in formula , we get

So, the culture will contain 11505 bacteria after four hours .

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

i believe the answer is d.

hope it you! : d
