okay Zegroes, fair enough.

Who do ya think (i usually press all the buttons until i get lucky its a hit or miss kinda thing)plus melody your the only one who answered it

All but one of the above (including yourself) are top answerers.  Who are you referring to Zegroes?

For a top answerer that answer was not very vague.....

How about a mac?

Mac's usually don't have a right click button .

Yes Zegroes.

I have a samsung S4Active phone and I don't know how to do hardly anything on it.

My method is to press button furiously and sometimes if I am very lucky something just works.  

This method is much more miss than hit.     lol.

Thanks Bertie, that does make sense. 

It was the last part I was most puzzled about though.

I guess I'll have to consider that part poorly defined.

Well well well i cant help you in general i dont think anyone can.....

for some reason when i copied and pasted the site, it would have a totally different link when you clicked on it...i guess cause the link was a site that needed a login?

Hi Everyone,

Great answers today were provided by CPhill, Heureka, Rosala, Alan, Bertie, Problem, admin, NinjaDevo, Zegroes,Kitty<3 and  Geele.  Thank you all.

Geele has only just become a member.  Welcome to web2.0calc forum.  We hope that you learn a lot and enjoy yourself here.  

Not much excitement today.  Some one tried to abuse the site by posting 14 'assignment' questions but members soon ignored them,  which seemed to be accepted as the correct response.  

It came to my attention today that some people do not know how to copy and paste web addresses so I prepared this.  The address is stored in the sticky thread called "information pages worth keeping or developing."  Maybe one of you can do a better job.  Mine is only good for windows operating systems.  Actually I just this instant received a pop up from Zegroes.  I think he was asking how to do it on a phone - but I could have got it wrong!

What if your on your phone or on your ps4.I hope you can understand the last one melody lol

Yes you are right Rosala, the pictures cannot be resized.  Maybe Andre will look at this sometime in the future.

trigonometry (noun), trigonometric (adjective): the first part of the word is from Greektrigon "triangle".

The second part of trigonometry is from Greek metron "a measure."

The Indo-European root is probably me- "to measure."

Trigonometry is literally the measuring (of angles and sides) of triangles. 

If you want a little more then look here.

All is rectified.  

Together we have managed to get Problem 8 extra points so now he is on +3 instead of -5

My negatives have all gone as well.   This is a very good outcome.  

Thank you.

I think it is fair to assume that the initial investment was 1 unit of money.

A=P(1+i)ⁿ

1.1296=1(1+i)¹⁹

1.1296^(1/19)=1+i

i=1.1296^(1/19)-1

$${{\mathtt{1.129\: \!6}}}^{\left({\frac{{\mathtt{1}}}{{\mathtt{19}}}}\right)}{\mathtt{\,-\,}}{\mathtt{1}} = {\mathtt{0.006\: \!434\: \!485\: \!969\: \!525\: \!8}}$$

monthly interest rate is approximately 0.643 %

When you say, the new car costs $22,500, is it inclusive of sales tax or before sales tax? If it is inclusive of sales tax, then:

(22,500 x  0.08) / 1.08 = 1,666.67 just multiply the 22,500 by 8% and then divide 108% and then you get the amount of sales tax included in the cost.

But if the cost of the care is before the sales tax, which means the 22,500 is only net amount with sales tax then, 

22,500 x 0.08 = 1,800

I'm assuming you want to find an angle with the same value as -cos(300)

cos(300) = 1/2   ....so ...-cos(300) = -1/2

So, you're looking for an angle with a cosine value of -1/2

This occurs at 120 degrees and at 240 degrees

The general answers would be

120 + n360   and   240 + n360          where n is an integer

Sorry

I am not able well enough in English

heureka

Rearranging 5x -10y =1, we have  10y = 5x -1....dividing by 10 on both sides, we get

y = (5/10)x - 1/10

Since we want to write an euation of a line perpendicular to this one, the slope of our line has the negative reciprocal slope of  (5/10) = -(10/5) = -2

So, using point - slope form, we have

y - (-2/7) = -2(x - 1/2)

y + 2/7 = -2x +1         subtract 2/7 from both sides

y = -2x + 5/7             I actually like this form because I can see the slope and y intercept right away, but putting it into Ax + By = C form, we have   (by multiplying both sides by 7)

7y = -14x + 5        

14x + 7y = 5

And there you go.......

$$\frac{4x}{5}+\frac{x}{3}-x\\\\
=\frac{12x}{15}+\frac{5x}{15}-\frac{15x}{15}\\\\
=\frac{2x}{15}$$

Hi Alan,

thank you.

Please proof your equation.

Many Greetings

Yes, it is an actual calculation. However, it is crude.

I will post an explanation and clarification in the next 12 hours.

If the daily balance of my account is $100 and the monthly interest is 90%, then what will my account balance be at in 10 years, starting at $7500

Okay, now I am looking properly.

I don't understand.  Is there $100 in the account at the beginning of $7500 ?

Could you please explain what those 2 amounts are?

Thank you.

90% interest per month WOW I want my money in THAT account.  

Then again,  you know what they say; If it seems to good to be true than it probably is too good to be true.

My money is staying under the bed.  And, in 10 years, if my house hasn't burnt down and I have not been robbed I will have $100.

(don't worry I will look at giving you a proper answer.)
