This thread is dedicated to the discussion on what makes a good blueberry muffin.


Oh yeah, and if you have any homework/school questions feel free to post them here

Call me retarded, but I don't understand what it means when somebody says something like "it changed by a factor of 4"

and this whole physics lab is pretty much that

For example, one question is "If a moving cart makes a sticky/inelastic collision with a stationary cart of equal mass, by what factor will the cart's velocity change?"

Although my teacher gave the class this formula to "help find the factor, if you can't do it mentally"

MiVi + MtVt = MiVi + MtVt' ('=prime) (i=incident, t=target)

For pretty much all of them I ended up with Vt' = .16

Now I know that 1/6 is .167,

but I don't understand how I translate that to "by what factor"

Okay.. uhmmm... I'll type this as best I can. My way of typing exponents is ^#.

6 + 3^2(4)
----------- = y
7-1

I don't even know what this is supposed to be, it just says "solve". Do you solve the problems using the Order of Operations and replace 'y' with your answer/fraction or..

I'd like to know wtf this is and how to solve it and other nice things.

[user472884]

yep.


6 + 3^2(4)
----------- = y
7-1

(assuming that the exponent is multiplied by 4)

6 + 3^8
----------- = y
7-1

6 + 6561
----------- = y
6

6567
----------- = y
6

(simplified)

2189
----- = y
2

Me thinks, at least

but with my track record so far this semester I could be totally off

[Azhiri]

Your guess is... actually probably a lot more accurate than mine so I'll take your word for it.

THANK YOU <3

wait

no

hold on

The exponent is.. the.. the three is supposed to be squared. You know, 3 with a little bitty 2 by it. 3 squared, 3 x 3

NNNNNNNNOOOOOOOOOOOOOOOOOOOOOO-

Edit:

oh, it's three squared times four?

lemme see hmnyah

6 + 3^2(4)
----------- = y
7-1

(assuming that the exponent is multiplied by 4)

6 + 9(4)
----------- = y
6


6 + (36)
----------- = y
6


42
----- = y
6

42
----- = y
6

Y=7

That seems more reasonable.

[Azhiri]

Yes.

Edit:

OKIES

thanks f'real this time <3

Now, answer my question.

Or else you will have exactly five Ninjas stalking you relentlessly until you cease to live.
