Ok but thanks!

Yes i suppose so but I would not call it a formula.    

Like CPhill said NO

It can have 5 "directions" which means a maximum of 4 turning points.

Directions is my word, it is not a proper technical word.

Ok thank you.

formula for these questions:

$${\frac{{\mathtt{a}}}{{\mathtt{b}}}}{\mathtt{\,\times\,}}{\mathtt{100}} = {\mathtt{c}}$$%

You put e^2 into the calculator on the home page.

$${\frac{{\mathtt{25}}}{{\mathtt{40}}}}{\mathtt{\,\times\,}}{\mathtt{100}} = {\frac{{\mathtt{125}}}{{\mathtt{2}}}} = {\mathtt{62.5}}$$     and add the percent sign yourself afterwards.

Why hello! I am struggling doing my homework! But thank you for asking!

(7+ 1/4) *(9+ 1/4)

now you can do it on the web2 calc on the home page.

Thanks! 

What is the LHS?

hi Flabujah,

I am very well thank you.

This is a little equation that you are being asked to rearrange.

$$ax=b\\$$

You want the x out the front by itself.   SO you have to get rid of the  $$a$$

You can do this by dividing the LHS by $$a$$   but the equation must stay balanced.

Whatever you do to one side you must also do to the other side.

so this is what happens

$$\\ax=b\\\\
\dfrac{\not{a} x}{\not{a}}=\dfrac{b}{a}\\\\
x=\dfrac{b}{a}\\\\$$

$${\frac{{\mathtt{25}}}{{\mathtt{40}}}}{\mathtt{\,\times\,}}{\mathtt{100}}\% = {\frac{{\mathtt{5}}}{{\mathtt{8}}}} = {\mathtt{0.625}}$$

i am confused. I will only write the fraction. Ahh! So every time that I find the percent of something, I always have to use the following method.

$${\frac{{\mathtt{a}}}{{\mathtt{b}}}}{\mathtt{\,\times\,}}{\mathtt{100}}\%$$

Do I use that method above?

Thanks! Later on, I will post something about factorials

DS...those "exclamation marks" are called "factorials"....in simple terms, n!  = the product of the first "n" positive integers......for example:

3!  = the product of the first three positive integers = 3x 2 x 1  = 6

4! = the product of the first four positive integeers = 4 x 3 x 2 x 1  = 24

......etc......

This is a very important idea in statistics and probability. It's used to "count" things.... (sets, arrangements of objects, etc.)

Hope that helps  !!!

you start by saying what fraction of 40 is 25

and the answer is 25/40

now to change it into a percentage you multiply by 100 and add a % sign

25/40*100%    

Oh. I now get it. Even on the first post, I wrote out 8! Interesting...

No....the maximum number of turning points in a polynomial of "n" degrees = n-1

To see, this......consider a polynomial of "n" degees that has "n" real roots. The relative "maximums" and "minimums" of this polynomial (i.e., the "turning points") will occur "between" these roots and none will occur on either side of the bounds on these roots.  And the maxiumum number of extrema "between"  the "n" roots  = n-1 ...... !!!

Therefore, a 5th degree polynomial has, at max, 4 turning points

What are the exclamation marks used for???

14/3+25/6=28/6+25/6=53/6  NOT 53/3

You're on fire, Melody!

You are the chose one...

Use asin

asin(0.3456)

5 x 2^2 + 20 x 2^2 - 20xy

5*4+20*4-20xy

=100-20xy

It is an imaginary number called i
