Question

♥ Help Please! ♥

1. Henrietta did an experiment. She started out with 800 bacteria cells. She found that the growth rate of the bacteria cells was 3.2%. Sketch the graph that represents the situation. Label the y-intercept and the point that represents the projected bacteria population 35 h from the time Henrietta started the experiment.

♥ Thank You! ♥

Answer 2

what is the question? I only see info

Answer 3

"Sketch the graph that represents the situation."

Answer 4

I remember seeing a similar question in peeranswer 🤔

Answer 5

Information is insufficient or incomplete. A growth rate of "3.2%" doesn't mean anything. We need a time period. Hours? Minutes? Days?

Answer 6

That there is all it gave me

Answer 7

@3mar

Answer 8

Could you give me 3 min, please?

Answer 9

Sure

Answer 10

Ouuu, you're green now!!!
Congratz! ♥

Answer 11

I am so Sorry for being late for you, sister!

and thanks very much for your concern!
Praise for Allah that I am green now!

Answer 12

No problem

Answer 13

Well, if we ASSUME it mean "3.2% per hour", then we can proceed.

Answer 14

For such problem, you would deal with exponential growth or decay!
are you familiar with it?

Answer 15

"She started out with 800 bacteria cells"
that means: at the beginning of the experiment (t=0) the number of bacteria cells was 800
P=800 at t=0

"She found that the growth rate of the bacteria cells was 3.2%."
that means:
after on hour: bacteria cells numbers increased by (0.032*800)=25.6
then it became = 800+25.6=825.6

and so on!

So you can represent that growth by the function:

\[\Huge P=a*b^t\]
where a=800
and t=1+0.032

Answer 16

@sissyedgar
Did you get the idea?

Try it!

Put t=0, then t=1, ....
what you got!?

Answer 17

So sorry.
I was in class!

Answer 18

No problem at all!
I hope you did well in that class!

Answer 19

I am with you if you faced any difficulties!
Let me know where you are back!

Answer 20

Ok, I'm back.
I ended up having back to back classes and worked on this problem a smidge with my teacher.
We found the equation but I still have to graph it

Answer 21

\[\Huge {P=\color{DeepPink }a*\color{HotPink }b^t}\]
\[\Huge {P=\color{DeepPink }{800}*\color{HotPink }{1.032}^t}\]
and t in hours, and P is bacteria cells number.

Try to graph it using this cool and interesting graphing calculator!

If you still need help, I am at your service!

Answer 22

We figured it out but thank you very much..
Though we found the equation to be.......
p=800e^(3.2%*35)

Answer 23

Nice.
Happy to know that.

Any Help... Any Time...

Answer 24

I think it is just like that!
