A petri dish contains 8 bacteria. Each hour, the number of bacteria doubles. After how many hours will there be 400 bacteria? Round to the nearest tenth of an hour.

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i

multiply then divide

step-by-step explanation:

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
