because pi is pi.

how do you graph (x-16)^2=(1/2)(y-8)?? Obviously this is a parabola and the vertex is (16,8) but where do I go from there?? What is the focus etc? How do I know what the rest of the points are on the graph? 

This is of the form

\((x-h)^2=4a(y-k)\\ h=16,k=8,a=1/8\\ (x-16)^2=4*\frac{1}{8}(y-8)\\ Vertex\;\;(16,8)\\ focal\; length =\frac{1}{8} \text { so focus is }(16,8.125)\\ Latus\;r****m\;is\; 4a=0.5\; units \;long\;\\\ \text{so the ends of the latus r****m are }(16-0.25,8.125)\;\;and\;\;(16+0.25,8.125)\\ \text{i.e. two more points on the graph are }(15.75,8.125)\;\;and\;\;(16.25,8.125)\\ \)

Here is the graph :)

Any questions?  Just ask. :)

N= ‎kg ⋅ m ⋅ s^-2

\(70000  ‎kg ⋅ m ⋅ s^{-2}m^{-2} \times 132\;µɛ\; \times 24.66/56.5mm \times 3.14/2\\ 70000  ‎kg ⋅ s^{-2}m^{-1} \times 132\;µɛ\; \times \frac{24.66}{56.5mm} \times \frac{3.14}{2}\\ \frac{70000  ‎kg }{ s^{2}m} \times 132\;µɛ\; \times \frac{24.66}{0.0565m} \times 1.57\\ \frac{70000*1.57 *24.66*132\;µɛ\ ‎kg }{ 0.0565s^{2}m^2} \\ \frac{6331640496\;µɛ\ ‎kg }{ s^{2}m^2} \\ 6331640496\;µɛ\; ‎kg \;s^{-2}m^{-2}\\ 6331640496 ‎Nm^{-3}\;µɛ\;\\ 6.331640496\times 10^9 ‎Nm^{-3}\;µɛ\;\\ \text{I do not know what }\;µɛ\; \text{ symbol means but you probably do. }\)

Go consult the Steam forums, they will be able to give you better answers. 

Idk why are you asking that kind of question on a site meant for maths questions?

Im gunna agree with SomeoneSomewhere because that would just be plain bs if 0 had a value.

how you doin

You can't divide by zero, it has no value.

2, if you by 1/5 mean one fifth. 

Though upper and lower case, I suspect that probably the two v's are intended to be the same, in which case, separating the variables,

\(\displaystyle \frac{dv}{dt}=9.8-2v\),

\(\displaystyle \frac{dv}{9.8-2v}=dt\),

\(\displaystyle \int\frac{1}{9.8-2v}dv=\int dt\),

etc..

Alternatively, you could write the equation as

\(\displaystyle \frac{dv}{dt}+2v=9.8\)

and use the integrating factor technique,

(multiply throughout by exp(2t)).

Tiggsy.

Here is another magic number puzzle :)

1, 4, 8, 9, 75 and  100              Magic number is   273

Answers here:

"if a^9b^5-a^5b^9=505440 what is the value of a^2b?"

How about:

.

WOW

Heureka has found 10 more.   I am VERY impressed!

So that is 11 answers altogether !    

I doubt anyone can better that :)

Heureka, maybe you would like to post another puzzle for us ?

1, 4, 8, 9, 75 and  100              Magic number is   273

\(\begin{array}{|rcll|} \hline 273 &=& 100+\dfrac{8+9\cdot(1+75)}{4} \\\\ 273 &=& 75 + \dfrac{100\cdot (9-1) - 8 }{4} \\\\ 273 &=& 75 + \dfrac{1+8\cdot 100 -9 }{4} \\\\ 273 &=& 75 + 9\cdot \left ( \dfrac{100-8 }{4} - 1\right ) \\\\ 273 &=& 1+8\cdot ( 100-75+9) \\\\ 273 &=& 1+8+4\cdot (75-9) \\\\ 273 &=& 9 + 4\cdot(75-8-1) \\\\ 273 &=& 75 +\dfrac{8\cdot (100-1)}{4} \\\\ 273 &=& 1+ 8\cdot( 9 +\dfrac{100}{4}) \\\\ 273 &=& 4\cdot 75 \cdot \left( 1-\dfrac{9}{100} \right) \\\\ \hline \end{array}\)

5 stars for your bruised brain  HSC.    

Just a little trivia :)

You know, where I live  HSC stands for Higher School Certificate which is a bit silly becasue there is no other school certificate :)

That is excellent guest :)

I did it exactly the same way.

I will now uncover my answer which may help people understand my thought processes.   

Number 5 doesn't even ADD UP!!!!! Sorry, friend!

I don't know if you will accept this:

[100 + 75] + 89 =237!
