Question

SOMEONE PLEASE HELP!!

Answer 1

Bacteria are the most common example of exponential growth. Research and find a bacterium that grows each hour exponentially and determine how much it
grows per hour.
a.Suppose you start with one single bacterium. Make a table of values showingthe number of bacteria that will be present after each hour for the first sixhours. Then determine how many bacteria will be present once 24 hourshave passed.
b.Explain why this table represents exponential growth.
c.Using this example, explain why any number raised to a power of zero isequal to one.
d.Write a rule for this table.
e.Suppose you started with 100 bacteria, but they still grew by the samegrowth factor. How would your rule change? Explain your answer

Answer 2

@bieber896 All of these questions are really easy to complete. But I'm not finding a bacteria that grows at an exponential rate for you. You have to do something yourself

Answer 3

Use Bing, Google or some other search to find that bacteria.

Answer 4

i cant find a bacteria i need help!

Answer 5

Can you paste a link or website as to what you are searching to find it so we can better understand what you need help with :P?

Answer 6

@EliLightE No, the math section is correct. It is about exponential growth. It's like a mix of math and science

Answer 7

@Needhelpstudying it doesn't matter if you think that the questions are easy. You have to take into consideration that this person asking the question is not you. Maybe he/she doesn't know how to find a bacteria that grows at an exponential rate. You don't know. Our job here is to help others. Not judge whether something is easy or not. Be kind and help or don't say anything at all next time.

Answer 8

do you still need help @Bieber896 ?

Answer 9

@RhondaSommer I agree, it was not my place to say it was easy. However, everyone is entitled to an opinion, so long as it is not offensive. Also, we can guide him through the problems, but we don't and should have to find the information and statistics for him first.

@crabbyoldgamer and I both told @Bieber896 how to find the information.

Answer 10

-_- sorry for raging at you

Answer 11

@RhondaSommer yes i do and thanks for having my back haha

Answer 12

@RhondaSommer No problem :)

@Bieber896 What exactly have you tried searching?

Answer 13

back; do you have a selected bacteria?

Answer 14

@bieber896 You have to do something urself. Find the bacteria, and I'll help you with all the questions

Answer 15

@Needhelpstudying sounds good :)

Answer 16

I tried searching for a bacteria that grows each hour exponentially but no luck

Answer 17

eColi?

Answer 18

There'd be no right or wrong answer if you were to choose a certain bacteria as a sample: "Bacteria are the most common example of exponential growth. Research and find a bacterium that grows each hour exponentially and determine how much it
grows per hour." You could invent your own equation for exponential growth of the bacteria population. Letting n = the number of bact. present, write \[n=Ne^t\]

Answer 19

where N is the population of bacteria at time zero.

More often than not, you'll see the form\[n=Ne ^{kt}\]

Answer 20

where k is the "growth constant."

You could choose an arbitrary value for k. The larger k is, the faster the bacteria multiply.

Answer 21

@Needhelpstudying okay well i think I'm going to chose eColi since its been studied on for a long time

Answer 22

@Bieber896 Alright, thats fine.

Answer 23

@Needhelpstudying here's the link that I'm looking at http://brominej12.imascientist.org.uk/2012/06/18/how-fast-does-bacteria-grow/

Answer 24

so in an hour, an ecoli cell will replicate into 8 cells

Answer 25

Alright, that's a good resource. It states that an e.Coli cell splits into half every 20 minutes. Alright, so N is the population at time 0.

Therefore, using @mathmale 's equation, N would be 1.

Answer 26

@Bieber896 Hold on, I might be wrong. Give me about 5 minutes

Answer 27

okay

Answer 28

@Bieber896 Bro, I'm really sorry but I have to leave. I'll try to get back soon, but I can't promise anything. Try tagging some other people like @triciaal and @mathmale

Answer 29

Bye

Answer 30

im a girl but okay see ya let me know when you get back

Answer 31

@triciaal do you think you can help?

Answer 32

@Ghostgate are you good in algebra?

Answer 33

what is it you are trying to do?

Answer 34

@Bieber896 Yes, for the most part I am, some areas I may have to review in order to understand it better, why do you have Algebra problems? I'll try to help you the best I can.

Answer 35

i just made a table let me insert it

Answer 36

you using this
e.Coli cell splits into half every 20 minutes

Answer 37

i would not phrase it as "splits in to half" what is weird
maybe "the population doubles ever 20 minutes" would be better

Answer 38

You messed up, it would have been "the population doubles *every* 20 minutes".

Answer 39

if that is the case, then the base of your exponential function could be 2, (since it doubles)
