Abiologist is researching a newly-discovered species of bacteria. he puts 200 bacteria into what he has determined to be a favorable growth medium. nine hours later, he measures 380 bacteria. assuming exponential growth, find the growth equation and use it to determine the number of bacteria after eight hours.

note: once you find the equation, round a and b to the nearest hundredth to determine the solution.

358

351

344

360

354.

Step-by-step explanation:

Exponential growth:

380 = 200e^(k*9)     where k is a constant to be found.

e^9k = 380/200 = 19/10

ln e^9k = ln 1.9

9k = ln 1.9

k = ln 1.9 / 9

k = 0.071

After 8 hours:

Number of bacteria =

200*e^(8*0.071)

= 354.

answer: i could not see part the question so ill explain how to get the answer

step-by-step explanation: for instance the distance she travele d is 10 and she traveled the same amout each mile so do 10 divided by how many miles she drove each time and you ge your answer.
