student	so sorry here.	6,857	172	[]
volunteer	Um, little bit lower.	6,857	173	[]
student	Right here.	6,857	174	[]
volunteer	Yeah	6,857	175	[]
student	All right	6,857	176	[]
student	I do, oh.	6,857	177	[]
student	OK. So, 1234 saving.	6,857	178	[]
student	So I go 3 and they go up 7.	6,857	179	[]
student	Look	6,857	180	[]
volunteer	Yeah, and you go up 7, but remember to do it from Y equals -1, not from when Y equals 0 on because you, you see the blue line? Like, that's where the reflection is over. So you start from that line when you count.	6,857	181	[]
student	Oh, OK, I appreciate.	6,857	182	[]
volunteer	Mm. Just, yeah, keep that in mind.	6,857	183	[]
student	Why, 2, sorry.	6,857	184	[]
volunteer	Mm	6,857	185	[]
volunteer	Yeah	6,857	186	[]
student	I'm a little songs. All righty. Mm.	6,857	187	[]
student	I'm going to one.	6,857	188	[]
student	Uh	6,857	189	[]
student	so it can be 6	6,857	190	[]
volunteer	Yes.	6,857	191	[]
student	Um, so.	6,857	192	[]
student	It's right here	6,857	193	[]
volunteer	Mm	6,857	194	[]
volunteer	Yeah	6,857	195	[]
student	Appreciate it. 2345, let's see.	6,857	196	[]
student	So here for this for last night.	6,857	197	[]
volunteer	Wait, hold on, let	6,857	198	[]
volunteer	me verify	6,857	199	[]
student	Yeah	6,857	200	[]
volunteer	Wait a minute. Oh, yeah, yeah, that's right.	6,857	201	[]
student	All right, so I do a thing with mouth real quick. But I think I understand it now too.	6,857	202	[]
student	So appreciate it too.	6,857	203	[]
volunteer	Um	6,857	204	[]
volunteer	I'm happy to help	6,857	205	[]
volunteer	Oh, you too. Thank you.	6,857	206	[]
volunteer	Bye.	6,857	207	[]
student	hi	7,278	0	[]
volunteer	hello!	7,278	1	[]
volunteer	What do you need help with today?	7,278	2	[]
student	I need help with this question	7,278	3	[]
volunteer	Okay! Give me a minute to read the question	7,278	4	[]
student	ok	7,278	5	[]
volunteer	I can't see the full question. Could you move the screen a little to the right?	7,278	6	[]
volunteer	thank you!	7,278	7	[]
volunteer	First, do you know the formula for continuous exponential decay?	7,278	8	[]
student	Yes	7,278	9	[]
volunteer	In the formula, you will plug a as the initial population which is a	7,278	10	[]
volunteer	and t = time taken which is 12 minutes	7,278	11	[]
volunteer	question a is just asking you to write the formula	7,278	12	[]
volunteer	For question b, you need to find r	7,278	13	[]
student	ok	7,278	14	[]
student	53	7,278	15	[]
volunteer	Did you get 53 for r?	7,278	16	[]
student	yes	7,278	17	[]
volunteer	r is not 53.	7,278	18	[]
volunteer	First you have to plug in your numbers in the formula, a=400, y=140, t=12 minutes in the formula y=ae^rt	7,278	19	[]
volunteer	did you plug in your values?	7,278	20	[]
student	yes	7,278	21	[]
volunteer	can you show me your equation?	7,278	22	[]
volunteer	Do you need help building your equation Maya?	7,278	23	[ { "pii_type": "PERSON", "surrogate": "Maya", "start": 40, "end": 44 } ]
student	yes	7,278	24	[]
volunteer	Okay. For y, we will substitute the value 140. Can you write y equal 140?	7,278	25	[]
volunteer	We do the same with a =400, and t = 12. Don't focus on question b yet. We are trying to find r	7,278	26	[]
volunteer	Great job Maya! That's the first step	7,278	27	[ { "pii_type": "PERSON", "surrogate": "Maya", "start": 10, "end": 14 } ]
volunteer	The next step is to divide both sides by 400. Can you do that for me?	7,278	28	[]
volunteer	Great! So what will our equation look like now?	7,278	29	[]
volunteer	Let's write it on the graph	7,278	30	[]
volunteer	So we can have more space!	7,278	31	[]
volunteer	This is what our equation looks like now. Can you see it on your screen Maya?	7,278	32	[ { "pii_type": "PERSON", "surrogate": "Maya", "start": 72, "end": 76 } ]
student	yes	7,278	33	[]
volunteer	good! You can reqrite 140/400 as 7/20	7,278	34	[]
volunteer	rewrite*	7,278	35	[]
volunteer	Now we take the natural log on both sides.	7,278	36	[]
volunteer	Did you do that Maya?	7,278	37	[ { "pii_type": "PERSON", "surrogate": "Maya", "start": 16, "end": 20 } ]
student	yes	7,278	38	[]
volunteer	So do you know what the equation will look like now?	7,278	39	[]
student	no	7,278	40	[]
volunteer	That's totally fine!	7,278	41	[]
volunteer	Once we take the natural log on both sides the equation will look like this	7,278	42	[]
volunteer	Did you get that?	7,278	43	[]
student	yes	7,278	44	[]
volunteer	What would you do next?	7,278	45	[]
volunteer	If you are not sure that is fine! Just let me know	7,278	46	[]
student	not sure	7,278	47	[]
volunteer	Thats okay!	7,278	48	[]
volunteer	Since we are finding r, we need r by itself.	7,278	49	[]
volunteer	So we divide both sides by 12 to get r by itself	7,278	50	[]
volunteer	We found r! Great job!	7,278	51	[]
volunteer	So now we have all the values we need for question b	7,278	52	[]
volunteer	we need a=400 and r=(ln(7/20))/12	7,278	53	[]
volunteer	Question be asks us how many bacteria there are 23 minutes after the beginning of the study. So we would substitute t with 23.	7,278	54	[]
volunteer	Do you know how to write the equation?	7,278	55	[]
student	no	7,278	56	[]
volunteer	thats okay.	7,278	57	[]
volunteer	I will write the new equation in pink.	7,278	58	[]
student	ok	7,278	59	[]
volunteer	this is what our new equation will look like	7,278	60	[]
volunteer	then we simplify our esponent	7,278	61	[]
volunteer	exponent*	7,278	62	[]
volunteer	You can rewrite this as	7,278	63	[]
