Bibs helping Bean not drop out

OpenStudy (anonymous):

@bibby

OpenStudy (bibby):

OpenStudy (anonymous):

Okay, this is gonna take awhile. You prepared?

OpenStudy (bibby):

anything for you

OpenStudy (anonymous):

Describe how the graph of y = 2log3(x – 4) + 2 compares to the parent graph. Discuss any changes in the asymptotes, domain, and range.

OpenStudy (bibby):

honestly,. no idea give me a bit

OpenStudy (anonymous):

Yep. Me neither, take your time. That's the hardest one.

OpenStudy (anonymous):

Wanna skip that one for now?

OpenStudy (bibby):

yes please, I can't really graph logarithmic equations

OpenStudy (anonymous):

Solve the equation. log(x + 7) – logx = 3

OpenStudy (bibby):

this looks n ice

OpenStudy (anonymous):

It's fine. obviously neither can i.-.

OpenStudy (anonymous):

I just need to know what the parent function is for that one. I get stumped there, then I can graph it on a calc.

OpenStudy (anonymous):

But yeah, this one for now Solve the equation. log(x + 7) – logx = 3

OpenStudy (bibby):

log(x + 7) – logx = 3 \(log(\frac{x+7}{x})=3\)

OpenStudy (bibby):

I guess you can then do 10^3=x+7/x

OpenStudy (anonymous):

So wait..

OpenStudy (anonymous):

1000=x+7/x

OpenStudy (bibby):

yeah, I'm honestly not positive that's right let's see

OpenStudy (anonymous):

wouldn't the x's cancel out?

OpenStudy (bibby):

do you guys use log to mean base 10 or base e also no, i don't think

OpenStudy (anonymous):

both.-. but if not specified then 10

OpenStudy (bibby):

because wolfram says x= 7/e^3-1 which is weird

OpenStudy (anonymous):

want the choice options

OpenStudy (bibby):

yeah

OpenStudy (anonymous):

3.5 142.7 0.0070 0.0707

OpenStudy (anonymous):

HAHA I DID THE LAST ONE ALL ON MY OWN

OpenStudy (bibby):

I'll write it out

OpenStudy (anonymous):

And okay :D I'm so proud of myself. I could fail and not care because i did the last one. ANYWAY

OpenStudy (bibby):

\(\huge \frac{x+7}{x}=1000\) 1000x=x+7 999x=7 x=7/999=0.00700700...

OpenStudy (bibby):

I meant C

OpenStudy (anonymous):

wait but how did you get 99+? Just subtracting the 1x? And then okay. I see it nvm

OpenStudy (bibby):

yeah

OpenStudy (anonymous):

Write the expression as a single logarithm. 5logby + 6logbx (1 point)

OpenStudy (anonymous):

Uhh hang on I'll write the equation.

OpenStudy (bibby):

i think I get it

OpenStudy (anonymous):

\[5\log_{b}y +6\log_{b}x \]

OpenStudy (bibby):

\(log_ba^n=nlog_ba\)

OpenStudy (anonymous):

5nlogba?

OpenStudy (anonymous):

it's starting to sound like we're talking clingon

OpenStudy (bibby):

talk dirty to me in klingon please 5logby + 6logbx = logby^5 + logbx^6 they have common base \(log_b(y^5x^6)\)

OpenStudy (anonymous):

So would that be my final answer? Dx DaneHchugh

OpenStudy (bibby):

what does that mean yes

OpenStudy (anonymous):

"If you want"

OpenStudy (bibby):

oh, nothing hotter than consensual relations

OpenStudy (anonymous):

XD omg.

OpenStudy (bibby):

<3

OpenStudy (anonymous):

<3 one moment

OpenStudy (anonymous):

leghlaHbe'bogh Hol 'oHbe' sexy

OpenStudy (bibby):

uh brb translator

OpenStudy (anonymous):

USE THE BING ONE

OpenStudy (anonymous):

omfg it comes out so wrong! I said the language is not sexy, and if you flip it around it says "a blind man, and language is not sexy.

OpenStudy (bibby):

I am a blind man you could make klingon work bbygurl

OpenStudy (anonymous):

WELL ITS N?OT

OpenStudy (bibby):

:( don't yell at me

OpenStudy (anonymous):

.-. I'm kidding

OpenStudy (bibby):

me too

OpenStudy (anonymous):

Okok this is getting hard again hang on

OpenStudy (bibby):

hehehehe

OpenStudy (anonymous):

HANG ON LOL GET IT

OpenStudy (bibby):

i dont

OpenStudy (anonymous):

I'm getting frustrated hang on.

OpenStudy (bibby):

you better get used to that if we become item

OpenStudy (anonymous):

XD shut up bibs

OpenStudy (bibby):

:X

OpenStudy (anonymous):

The half-life of a certain radioactive material is 68 hours. An initial amount of the material has a mass of 641 kg. Write an exponential function that models the decay of this material. Find how much radioactive material remains after 4 hours. Round your answer to the nearest thousandth. (1 point)

OpenStudy (bibby):

\(y=a(1-r)^x\) \(y=641(1-r)^{68}\) a=initial amount r-rate x-time

OpenStudy (bibby):

I'm not sure what r would be

OpenStudy (anonymous):

Eh, I got that much right. I'll do my final tomorow

OpenStudy (bibby):

let's do more stuff wehile we're here

OpenStudy (anonymous):

More math?

OpenStudy (bibby):

I was hoping hot internet sex while I pretend to be a cute young lifeguard boy that noticed you in summer camp but math is good too

OpenStudy (anonymous):

._. lifeguards are almost all shallow

OpenStudy (bibby):

did I dig up old wounds

OpenStudy (anonymous):

No I can't swim

OpenStudy (anonymous):

Just jealous of those who can

OpenStudy (anonymous):

Lets take an intermission of math for a second though because my head hurts

OpenStudy (bibby):

ok, we'll talk about everything that isn't math

OpenStudy (anonymous):

like i have three dogs

OpenStudy (bibby):

I have 3-3 dogs

OpenStudy (anonymous):

0?

OpenStudy (anonymous):

WHY

OpenStudy (bibby):

idk, my parents aren't pet people I want to get a cat

OpenStudy (anonymous):

I want to be a vet

OpenStudy (bibby):

give me horse tranquilizer

OpenStudy (anonymous):

Deal

OpenStudy (bibby):

what do I offer you

OpenStudy (anonymous):

This tutoring stuff

OpenStudy (bibby):

I do that out of the goodness of my heart also this is the only female interaction i get

OpenStudy (anonymous):

Well, i'm here. BIbs can i ask you somethin?

OpenStudy (bibby):

anything you don't have to ask permission

OpenStudy (anonymous):

Is that you in your picture?

OpenStudy (bibby):

yes

OpenStudy (anonymous):

Yeeet you say you're a girl cx

OpenStudy (bibby):

the 2 aren't mutually exclusive

OpenStudy (anonymous):

Don't riddle me.

OpenStudy (bibby):

I'm just a bored old man that wants to crossdress but doesn't because he lives with his parents
