9. a biologist is researching a newly-discovered species of bacteria. at time t = 0 hours, he puts seventy-five bacteria into what he has determined to be a favorable growth medium. four hours later, he measures 325 bacteria. assuming exponential growth, what is the growth constant "k" for the bacteria? (round k to two decimal places.)

Step-by-step explanation:

A biologist is researching a newly-discovered species of bacteria.

at time t=0 hours, he puts one hundred bacteria into what he has determined to

be a favorable growth medium.

Six hours later, he measures 450 bacteria.

Find an exponential equation that approximates the information.

:

find k, the growth factor

100*(2^(6/k)) = 450

Divide both sides by 100

2^(6/k) = 4.5

use logs here

log(2^(6/k)) = log(4.5)

:

log(2) = log(4.5)

=  

= 2.17

k =  

k = 2.765 is the growth factor

:

A = Ao*2^(t/2.765), the exponential equation

where

Ao = initial amt

A = amt after t hrs

the most boring thing ever written

step-by-step explanation:

i am writing something. yes, i plan to make it the most boring thing ever written. i go to the store. a car is parked. many cars are parked or moving. some are blue. some are tan. they have windows. in the store, there are items for sale. these include such things as soap, detergent, magazines, and lettuce. you can enhance your life with these products. soap can be used for bathing, be it in a bathtub or in a shower. apply the soap to your body and rinse. detergent is used to wash clothes. place your dirty clothes into a washing machine and add some detergent as directed on the box. select the appropriate settings on your washing machine and you should be ready to begin. magazines are stapled reading material made with glossy paper, and they cover a wide variety of topics, ranging from news and politics to business and stock market information. some magazines are concerned with more recreational topics, like sports card collecting or different kinds of hairstyles. lettuce is a vegetable.
