Use the formula p=ie^kt. a bacterial culture has an initial population of 1 . if its population declines to 3000 in 8 hours , what will it be at the end of 10 hours?

27

Step-by-step explanation:

Using the formula P =Ie^kt.

If bacterial culture has an initial population of 10,000, the equation becomes,

10,000 = Ie^k(0)... 1 where t = 0

10000 = I

If its population declines to 3000 in 8 hours, P = 3000 and t = 8hours

This gives;

3000 = Ie^8k... 2

From equation 2, we take natural logarithm of both sides to have;

ln3000 = I lne^8k

ln3000 = 8Ik

k = ln3000/8I

k = ln3000/8(10000) since I is 10000

k = ln3000/80000

k = 8/80000

k = 0.0001

At the end of 10hours, the population will become;

Since P = Ie^kt

I = 10000 k = 0.0001 and t = 10

P = 10000e^(0.0001×10)

P = 10000e^0.001

P = 10000×0.0027

P = 27

The population of the bacteria will have reduced to about 27population after 10hours

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
