what are alternate ways to write the equation "x^2 / y^3"? thanks

Well another way is to write it like this: (x^2) x ( 1/y^3)

2215.9842057198873456

What is that sposed to mean?

arccsc(-2)?

=-Pi/6=-.523598.......etc.

Okau what is it?

What is 16000=4*pi*r3, what is r?

4 X 3.14159265358....X r X3 This is assuming you meant r3?

Then 16000/above answer(37.699.......)

Then r=424.413.....etc. But if you meant to write r^3, then that's a different calculation!. Then you would have 4 x pi x r^3=16000

Then 16000/(4xPi xr^3)=1,273.239...etc,

Or r^3=1,273.239  Then you take the logs of both sides

3 x log r=log 1,273,239

3 x log r=3.104910.....etc., =3.104910/3=1.034970.....etc.

So r=1.034970. Now remember this is a "Log" of r, so we must raise 10 to this power=10.838520....etc.

So r=10.838520

A chair marked at $300 was sold for $250.what percent discount was given?

Just divide 250/300=.8333333.....etc.

Then subtract it from 1, thus:

1 - .83333333=.1666666...... Then multiply by 100 to give you percentage discount=16.67%

Sam purchased a ball for $48 and sold it for $56. What was his profit percentage?

Well, just divide the selling price by the purchase price as follows:

56/48=1.1666666.......etc.

Then subtract 1 & multiply by 100

1.16666666-1=.166666666 x 100=16.67%

Alg 1 Help ?

For graphing question, you should go to computing engines such as WolframAlpha here:

what is the square root of pi?

Since Pi is irrational and goes on forever, you can't really take its square root.

However, for most purposes you can have as many digits of Pi as you want and then take the square root of that many digits. For example here is Pi to about 40 digits. 

For example here is pi to about 40 digits: 3.141592653589793238462643383279502884197. Now you can take the square root of

these 40 digits and you get:1.772453850905516027298167483341145182798

Ok Mr smart butt.

How many knights can you put on there without them attacking another one another?

That should be worth 2 cookies. hahaha

is 57 a prime number?

The short answer is No! Why? Because if you add the 2 numbers together you get 5+7=12

Since 12 is divisible by 3 then the whole number is divisible by 3. 57/3=19

the mortal of this Math Question:

VIDEO GAMES ARE NOT A WASTE OF TIME YOU FOOLS!

video games are both benificial and joyful ways to understand the world

without video games, the world will not only be boring, but also it would be misunderstood

video games give people, even scientists, a better way to understand the world

if only video games were invented in the 1600s, the Scientific Revolution would be a lot more better to comba the Cathoilic Church

so the next time I hear someone or see someone wearing an anti-video game clothes, im gonna punch them straight in the face, even if the sentence is death, but they cant shut me down, cuz this forums, and the school, and the world, would be so empty without me

I notice a new trend here

now this is a job for me!

this is exactly the same concept Clash of Clans is when it coes to training armies

a certain troop always takes up certain housing space

a king takes up 4 tiles in this game of Chess (which no offense, but i find it boring)

theres 8 tiles on one side of the chess board

its a square board

so:

$${\mathtt{8}}{\mathtt{\,\times\,}}{\mathtt{8}} = {\mathtt{64}}$$

a king, if placement starts in the corner, takes up 4 spaces, instead of the usual in the middle 9 spaces

so, we divide

$${\frac{{\mathtt{64}}}{{\mathtt{4}}}} = {\mathtt{16}}$$

in a game of chess, you can place 16 kings on a chess board without blood spreeing in your board

8(66+2/3)

=8*66+8*2/3

=528+16/3

=528+5+1/3

=533 and 1/3

check

$$\left({\mathtt{66}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{2}}}{{\mathtt{3}}}}\right){\mathtt{\,\times\,}}{\mathtt{8}} = {\frac{{\mathtt{1\,600}}}{{\mathtt{3}}}} = {\mathtt{533.333\: \!333\: \!333\: \!333\: \!333\: \!3}}$$

-3[(5-6)^2+6]^2

=-3*[(-1)^2+6]^2

=-3*[1+6]^2

=-3*[7]^2

=-3*49

= -147

It is not What is tan inverse multiplied by (10/5)

It is  tan inverse of (10/5)

this can be written as 

$$tan^{-1}(2)\qquad or \qquad atan(2)$$

The brackets are not always necessary :)

Remember that 1.5 = 3/2.....so we have

(4/9)^3/2  = [(4/9)^1/2]³ =  [√(4/9)]³   = (2/3)³ = 8/27

Why don't you join up?  You are asking some good questions today :)

$$\\\left(\frac{4}{9}\right)^{1.5}\\\\
=\left(\frac{4}{9}\right)^{3/2}\\\\
=\left(\left(\frac{4}{9}\right)^{1/2}\right)^3\\\\
=\left(\frac{\sqrt4}{\sqrt9}\right)^3\\\\
=\left(\frac{2}{3}\right)^3\\\\
=\frac{2^3}{3^3}\\\\
=\frac{8}{27}\\\\$$

I think you want to know this :

tan^-1 (10/5)  =  about 63.43°

{Note....we aren't  "multiplying" the tangent inverse by 10/5, we're just finding the angle that has a tangent value of 10/5.......don't get confused, here }

Chris, the minus on the second one is NOT inside the bracket :/

Oh I see the confusion.

The heading and the question are different.

I did the question in the body of the post and CPhill did the question in the heading.
