The other answers are wrong.

It's 5.6 X 10^-5

nobody sould have to do math, am i right?

If you know angle, A, say, and the side opposite A, call it a; together with side b, and you want to know angle B (opposite side b), then use the sine rule:  sin(B)/b = sin(A)/a

Once you have found sin(B) from this you can find angle B by using sin^-1.

10⁴ and 10^-3 respectively.

[6000(1+.05/2)^6]^2

[6000*(1+.025)^6]^2

[6000*(1.025)^6]^2

[6000* 1.1596934]^2

[6,958.16050]^2=48,415,997.67287 And that's your answer.

2 (l (h+w)+hw)
(assuming depth l, height h, and width w)

That's the area of a rectangular dolid.

You could try WolframAlpha.  For example:

In our "reference material" sticky topic there are a number of references to online statistics calculators.

You should be able to find something helpful there I think.  :/

This should help  :)

twice a number plus 4 equals 6 what is the number?

OK, Let us say we have a number x?

So, 2*x + 4=6, we move 4 to the right hand side & change the sign from + to - and we have

2x=6 - 4=2x=2 we divide both sides by 2,

x=2/2=1, So your number would be 1.

The answer is 10^26. OK?

xy = 12 «» (4 +y) y = 12 <= y” +4y – 12 = 0 xy = <= (y – 6)

These are logs to the base 10, so log 15 = 1.176

Is 'a' a function or a constant?

Hi :)

make 3 circles

that is not allowed here

The cosine of any angle must lie between +1 and -1, so it cannot equal 19.4.

Just multiply 25 by 1.95.
