<span>for that, what you need is a calculator... like say a TI(texas instruments) 83 or 83plus or higher, will do regressions, if you have an android device like a phone or tablet, you can also get an app from the play store "Andie's graph", is a TI calculator emulator, it works just like the calculator itself, you'd only need the ROM
</span><span>that said, you can also use some online calculators for that.
</span>
<span>I could give you a direct link to one, but this site has issues with links, if you do a quick search in google for "keisan exponential regression calculator", it should be the first link, is from the Casio site.
</span>
<span>you could do regressions in a spreadsheet as well.... you could check online for an "addin" or "extension", if you use MS Excel, pretty sure there are some addins for regressions.
</span>
if I recall correctly, Excel does regressions natively, but the addins are just frontends, is all, just some added interfacing.
anyhow, if you have an Android device Andie Graph works peachy, I have an 83plus, 84, 86 in it, they all work just like my old TI83plus.
there's also an app in the play store called Graph89, is an emulator for a TI89, the same you need a tiny little file, and texas instruments provides them, have also, works peachy too.
Answer:
443 jelly boys
Step-by-step explanation:
the raius is 3.5, then square it is 12.25, multiplied by pie, 12.25*3.14159=38.4844775, then times 11.5 is 442.57149125, aproximately 443.
3-4(-2-4J)=118-11
3+8+16J=107
11+16J=107
16J=96
J=6
140m divided by 7 days
20m a day
20 divided by 17
1.8
about 4 days you would need to fill the tank
17% gets turned into .17, so we can multiply. You have to multiply because he earns 17% of tips.
17% of 200 is 34
200×.17=34
So he earns $34 in tips
