500x100= 50,000 and 500x500=250,000 Here are both off the answers!

In the subject box it is "500x100" then you put "five hundred x five hundred" which one is it? 

Omigosh i put it in the calculator and it said infinity!

No it isn't Isabella.

it is an enormous number :)

Hi! The answer is 1.0632092060812032074677973016087e+1407. just round. Hope this helped!

$$\int\;lnx\;dx=x(lnx-1)+c$$

Sin2(280°+2Π) x Log(Cos85°) + tanΠ2 - √567

Is this your question?  If it is you can put it straight onto the home page calculator.

$$Sin^2(280+2\pi) \times log(Cos85) + tan2\pi - \sqrt{567}$$

Did you want it be discussed.  

For starters 

$$Sin^2(280+2\pi) =sin^2(280)$$ 

This is because the sine curve has a period of 2pi.  After that it just repeats.

$$tan(2\pi)=0$$

$$\begin{array}{rll}
gradient&=&\frac{rise}{run}\\\\
&=&\frac{y_2-y_1}{x_2-x_1}\\\\
&=&\frac{-5-4}{1-\;-4}\\\\
&=&\frac{-9}{5}\\\\



\end{array}$$

Hi all,

Our great answerers today were Captain123, geno3141, Jazzcat92, mathhelpneeded, CPhill, Heureka, Kitty<3, saseflower, Alex4life, Hugekase.  A big thank you to each of you :)

Interest Posts:

1)  Mathhelpneeded messaged this to me.  

"Happy7 and CPhill are incredible!  I want you to add this in your wrap."

Thanks Mathhelpneeded.  It makes our day when people show their appreciation.  Happy7 and CPhill will be chuffed (very pleased).    

I think that one of the most positive things about this site is that it allows a little culture exchange.

I find other people's cultures very interesting to learn about and the interaction also helps make people of the world a little more understanding and tolerant of each other.  

CPhill expressed these same sentiments today when he bought my attention to this post.

It is strange wording but I think this is what is meant 

Are you sure that was x-5 perhaps it should have been x=5     

$$\\f(x)=x^2+3\\\\
f(x-5)=(x-5)^2+3=x^2-10x+25+3=x^2-10x+28\\\\
f(10)=10^2+3=100+3=103$$

There is a calc on the home page - why don't you find out :)

You say that it is false  

$$\\8x(2x+\frac{5y}{4x})\\\\
=8x*2x+8x*\frac{5y}{4x}\\\\
=16x^2+10y\\\\$$

We are not here to do all you homework for you Angelica  

please use the calc on the home page 

please use the calc on the home page.

I=Prt

120=1000*r*2

120=2000*r

120/2000=r

r=12/200=6/100

r=6%

Inverse trig functions (also called arc trig)  are used to find ANGLES   

You are missing a bracket so I will add one on the end.  :)

sqrt(3^0-(-2^3)

$$\\\sqrt{3^0-(-2^3)}\\
=\sqrt{1-(-1*2^3)}\\
=\sqrt{1-(-1*8)}\\
=\sqrt{1-(-8)}\\
=\sqrt{9}\\
=3$$

That is a really good way to do it mathhelpneeded  

That is excellent advice anon :)

You are missing a zero just on the last line Heureka :)
