Hi Melody,

i have installed Latex on my Computer. The setup include a TexStudio.

See picture:

all free-software.

Then i have snapped it as image into web2.0calc.

I do it all directly on my hard drive.

Here i think we have a minimal latex.

That sounds right to me EP.

Oh

What is black and white and goes round and round?

A penguin in the washing machine! 

Ok ok it is not my fault.  I am looking after a 4 year old and I get ALL the good jokes  LOL

1+1+1+1+1+1+1+1+1+1+1x0+1

= 10+0+1

=11

{.0950(.70)}/{1-.0950(.70)}

Just use normal round brackets

(.0950(.70))/(1-.0950(.70)) = 0.0712372790573112

For what values of a does the system of equations of linear equations
in the variables x and y have infinitely many solutions?
\(\begin{array}{|rcll|} \hline ay &=& -\frac{3}{4}x \\ 4x-5y &=& 0 \\ \hline \end{array} \)

\(\begin{array}{|rcll|} \hline ay &=& -\frac{3}{4}x \quad &| \quad + \frac{3}{4}x \\ \frac{3}{4}x + ay &=& 0 \quad &| \quad \cdot \frac{16}{3} \\ 4x + \frac{16}{3}ay &=& 0 \\ \hline \end{array}\)

infinitely many solutions, if  \(\frac{16}{3}a = -5\)

\(\begin{array}{|rcll|} \hline \frac{16}{3}a &=& -5 \quad &| \quad \cdot \frac{3}{16} \\ a &=& -5\cdot \frac{3}{16} \\ a &=& -\frac{15}{16} \\ \hline \end{array}\)

Thanks very much Heureka,

But

This does not work in this forum though does it?  I cannot make it work :/ I asume the polynom package is not included. :(

Do you do it all directly on your hard drive or do you go to somewhere else on the net to do LaTex like this ?

what is 0.4 recurring as a fraction

\(\begin{array}{|rcll|} \hline 10\cdot 0.\bar{4} &=& 4.\bar{4} \\ 1\cdot 0.\bar{4} &=& 0.\bar{4} \\\\ 10\cdot 0.\bar{4} - 1\cdot 0.\bar{4} &=& 4.\bar{4}-0.\bar{4} \\ 9\cdot 0.\bar{4} &=& 4 \\ 0.\bar{4} &=& \frac{4}{9} \\ \mathbf{ 0.4\ recurring } &\mathbf{=}& \mathbf{ \frac{4}{9} }\\ \hline \end{array} \)

11 17 23 29 find, in terms of n, an expression for the nth term of this arithmatic sequence

\(\begin{array}{|rcll|} \hline a_1 = 11+0\cdot 6 &=& 11 \\ a_2 = 11+1\cdot 6 &=& 17 \\ a_3 = 11+2\cdot 6 &=& 23 \\ a_4 = 11+3\cdot 6 &=& 29 \\ \dots \\ a_n = 11+(n-1)\cdot 6 &=& 5+6n \\ \hline \end{array} \)

What is the Fibonacci Sequence?

A 1.2 kg block is hung from a vertical spring, causing the spring to stretch by 2.4 cm How much further will the spring stretch if a 0.60 kg block is added to the 1.2 kg block?

\(1.2:2.4=(1.2+0.6):(2.4+x)\)

\(1.2\times2.4+1.2x=2.4\times1.8\)

\(1.2x=2.4\times1.8-1.2\times2.4\)

\(\large x=\frac{(2.4\times1.8-1.2\times2.4)cm\times kg}{1.2kg}\)

\(x = 1.2 cm\) 

\(The \ spring \ expands \ by \ a \ further \ 1.2cm.\)

I assume you mean  →  0.44.......

If so....we have      44/99 =  4/9

We take the distance between the center of the sphere and the point and subtract the radius of the sphere......

The sphere's  radius   = 6  and its center is (1, -2, 0)

So we have

√ [ (1 - 4)^2  + ( -2 - 0)^2 + (0 - 5)^2]  -  6   =  √ 38  -  6  ≈  0.1644 units

Basketball is full of a bunch of whiney babies! lmo.

arcsin or type sin^-1

What is the mean? 0.91 0.91 0.91 0.91 0.54 0.68 0.93 0.91 0.68

\(\begin{array}{|rcll|} \hline && \frac{0.91+ 0.91+ 0.91+ 0.91+ 0.54+ 0.68+ 0.93+ 0.91+ 0.68}{9} \\ &=& \frac{5\cdot 0.91 +2\cdot 0.68+ 0.54+ 0.93 }{9} \\ &=& \frac{7.38}{9} \\ &=& 0.82 \\ \hline \end{array}\)

If you want the hypotenuse....  √ [ (leg 1)^2 + (leg 2)^2 ]

If you want a leg  .....   √ [ ( hypotenuse)^2 - (leg)^2 ]

-4x+y=4

2x+2y=13

\(\begin{array}{|lrcll|} \hline (1) & -4x+y &=& 4 \\ & y = 4+4x \\ (2) & 2x+2y &=& 13 \\ & 2x+2[4+4x]&=& 13 \\ & 2x+8+8x &=& 13 \\ & 10x+8&=& 13 \\ & 10x&=& 13 -8 \\ & 10x&=& 5 \\ & x&=& \frac{5}{10} \\ & x&=& \frac12 \\ & \mathbf{x} & \mathbf{=} & \mathbf{0.5} \\\\ & y &=& 4+4x \\ & y &=& 4+4\cdot {\frac12} \\ & y &=& 4+2 \\ & \mathbf{y} & \mathbf{=} & \mathbf{6} \\ \hline \end{array}\)

I thought it was funny too. Sorry to hear of your illness. Some other time, perhaps?

Oh my goodness! That's hilarious! l have no explanation at all. l'm not feeling well at the moment...

hi Melody,

typesetting polynom division can easy be done with the polynom package:

I studied him and his followers thoroughly. A great sin in that cult was to urinate toward the sun.  I have an idea of why that was a sin, but I’d like your opinion.
