You can't get killed by math.  It may hurt your brain a little bit (aka a lot), but you won't die from math.

What's x?  If you tell me what x is, then I would be able to help you out, because I am studying that right now.

yes but if you created the system and you own it how can they prove you wrong since you created the system?

It's just like a claim in a debate.  You're right until someone can prove you wrong.

ugh yeah but such a weird word i almost always forget it thanks though

Remember  SOHCAHTOA

Sin is Opposite/Hypotenuse

Cos is Adjacent /Hypotenuse

Tan is Opposite/Adjacent 

B∪C is the set of all the items in B and C put together. {b, c, d, e, f}

A∩(B∪C) is the set of items that are common to A and to B∪C.  In this case that is {b, d}

B` is everything in the universal set that is not in B, namely {a, c}

B`∩C is the set of items common to B` and C, namely {c}

(B`∩C)` is everything in the universal set not in B`∩C.  So {a, b, d, e, f}

(B`∩C)`-A is the set of items left when you take those in A away from (B`∩C)`, so you are left with  {e, f}

$${\mathtt{2}}{\mathtt{\,\small\textbf+\,}}{\mathtt{x}} = {\mathtt{4}} \Rightarrow {\mathtt{x}} = {\mathtt{2}}$$

well just like anything else if you invented something new who can really prove you wrong.

if i understood this question right when i set it up it should be 36

the surface area would be pie times ratio times the original slant height plus pie times ratio squared 2 if you do that you should find the answer hope this helped

9x3 is one

fine alan was right ugh fine the great alan is right im sorry

Oh don’t worry about it, zegroes. A few more of these and you can join the Goldenleaf club. it is a great honor!

I’m trying to petition Admin to give a special golden leaf icon for that club. My last publicly posted petition was deleted, without ceremony nor comment. Pity. I thought it was a great idea. Unique talent should be recognized!

To find za/2 from 0.58*0.42*(za/2 /0.04)² = 718 first divide both sides by 0.58*0.42

(za/2 /0.04)² = 718/(0.58*0.42)

Take the square root of both sides

za/2/0.04 = ±√(718/(0.58*0.42))

Multiply both sides by 0.04

za/2 = ±0.04*√(718/(0.58*0.42))

$${\mathtt{0.04}}{\mathtt{\,\times\,}}{\sqrt{{\frac{{\mathtt{718}}}{\left({\mathtt{0.58}}{\mathtt{\,\times\,}}{\mathtt{0.42}}\right)}}}} = {\mathtt{2.171\: \!618\: \!693\: \!604\: \!038}}$$

So za/2 ≈ ±2.1716

you cant because math will only help you in life not hurt you.....ok maybe a little but once you get through it then yes definintly helps!

OK

So

27 =

9 * 3 =

3 * 3 * 3 =

3³

And that's it ......

Hope that helps

8x-3y=1

-2x-3y=11

OK...let's just subtract the second equation from the first.

We have

10x = -10

 So, x = -1     and to find y, we can substitute the "-1" for x in either of the two equations.

Using the first one, we have

8(-1)  - 3y   = 1

-8 -3y = 1

-3y = 9

y = -3

So, the solution is (-1,-3)

You should check that this is correct by substituting these values into the second equation.

So we have

10 = y(5)^2

10 = y(25)

0 = 25y - 10

0 = 5(y -2)

FOIL (First, Outer, Inner, Last)

x*x

x*-2

4*x

4*-2

x^2

-2x

4x

-8

The answer is x^2+2x-8

ugh fine the great alan is right im sorry....

zegroes said: well i tried giving him the easiest way i suppose......

Yes, but unfortunately you forgot part of the equation.  If you put x = 6 in the left-hand side you get 6(6+6) which is 6*12, which is not 36. The equation isn't one which factors nicely!  

Good try, but always check your answer by plugging it back into the original equation!

These are known as parametric equations.  Choose a range of values for t, calculate the corresponding values of x and y and plot y vs. x.  The graph below was calculated from 10000 values of t from 0 to 100 in steps of 0.01.

well i tried giving him the easiest way i suppose......

You can use the calculator here to solve this:

$${\mathtt{x}}{\mathtt{\,\times\,}}\left({\mathtt{x}}{\mathtt{\,\small\textbf+\,}}{\mathtt{6}}\right) = {\mathtt{36}} \Rightarrow \left\{ \begin{array}{l}{\mathtt{x}} = {\mathtt{\,-\,}}{\mathtt{3}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{5}}}}{\mathtt{\,-\,}}{\mathtt{3}}\\
{\mathtt{x}} = {\mathtt{3}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{5}}}}{\mathtt{\,-\,}}{\mathtt{3}}\\
\end{array} \right\} \Rightarrow \left\{ \begin{array}{l}{\mathtt{x}} = -{\mathtt{9.708\: \!203\: \!932\: \!499\: \!369\: \!1}}\\
{\mathtt{x}} = {\mathtt{3.708\: \!203\: \!932\: \!499\: \!369\: \!1}}\\
\end{array} \right\}$$

Note there are two solutions.

millimeters are a length and you can't have a length in a capacity(litres). You probably meant millilitres and there are 1000 millilitres in a litres. If you don't think thats right google it!
