Item 10 a bacterial culture quadruples in size every hour. you begin observing the number of bacteria 3 hours after the culture is prepared. the amount y of bacteria x hours after the culture is prepared is represented by y=192(4x−3). when will there be 200,000 bacteria? round your answer to the nearest hundredth. there will be 200,000 bacteria about hours after the culture is prepared.

There will be 200 000 bacteria after 8 hours

Step-by-step explanation:

The crop quadruples every hour.

x represents the number of hours that pass after preparing the crop

y represents the number of bacteria after x hours.

The equation for y in function of x  3 hours after observing the crop is:

We want to know after how long there will be 200 000 bacteria.

Then we make y = 200 000 and clear x.
