omg rock lee from naruto....XD

Lol no it's a study website

6sinθ−7=0    this has no solution........6 is as large as the first term can be....so

6 - 7  can never equal 0

14 = [ 2(h + 3) ] / 5      multiply both sides by 5

70 = 2 (h + 3)    divide both sides by 2

35   = h + 3      subtract 3  from both sides

32  =  h

All of them!

\(sin\left(cos^{-1}\left(\frac{x^2}{4-x^2}\right)\right)\)

We are looking for the sin of an angle (theta) with a cosine of   x^2 / ( 4 - x^2).....so we have...

sin (theta)   =  √ [ 1 - cos^2 (theta) ] =  [ 1 - [ (x^2)/(4-x^2)]^2 ] =  √ [x^4 - 8x^2 + 16 - x^4] / (4 - x^2)   =

√ {16 - 8x^2) / (4- x^2)    =  √ [ 4 (4 - 2x^2) ] / (4 - x^2)   =  2√(4 - 2x^2) / (4 - x^2)

Am I reading it right?

sin(cos^(-1)(x^2/(4 - x^2)))

Solve for x:
sqrt(1 - x^4/(4 - x^2)^2) = 0

Square both sides:
1 - x^4/(4 - x^2)^2 = 0

Bring 1 - x^4/(4 - x^2)^2 together using the common denominator (x^2 - 4)^2:
-(8 (x^2 - 2))/(x^2 - 4)^2 = 0

Divide both sides by -8:
(x^2 - 2)/(x^2 - 4)^2 = 0

Multiply both sides by (x^2 - 4)^2:
x^2 - 2 = 0

Add 2 to both sides:
x^2 = 2

Take the square root of both sides:
Answer: |x = sqrt(2)         or          x = -sqrt(2)

the correct answer is 77.25

L = (  1 + 1/3) W   = (4/3)W

And the  area   = L * W    ....so....

4800 =  4(/3)W * W

4800 = (4/3)W^2     multiply both sides by (3/4)

3600 = W^2     take the positive square root

60 in = W       and   L   =  (4/3)* 60   =   80 in

\(Tangent = \frac{Opposite}{Adjacent}\)

Since we already have the opposite, we need to solve for the adjacent.

Pythagoras: \(a^2 + b^2 = c^2\)

In this case: \(Opposite^2+Adjacent^2=Hypotenuse^2\)

Solve for adjacent:

                   \(Adjacent^2=Hypotenuse^2-Opposite^2\)

                   \(Adjacent = \sqrt{Hypotenuse^2-Opposite^2}\)

So, going back to the first equation (for tangent), we can plug in this for adjacent.

                   \(Tangent=\frac{Opposite}{\sqrt{Hypotenuse^2-Opposite^2}}\)

There we go! Use this equation ↑↑↑ to find tangent.

-6/11-(-1/4)

\(\large -\frac{6}{11-(-\frac{1}{4})}=-\frac{6}{11\frac{1}{4}}=-\frac{6}{\frac{45}{4}}=-6\times{\frac{4}{45}}=-\frac{8}{15}\)

Tan = Opposite side / Adjacent side

Expand the following:
(k + 1) (k - 5)

(k + 1) (k - 5) = (k) (k) + (k) (-5) + (1) (k) + (1) (-5):
k k + k - 5 k - 5

k k = k^2:
k^2 + k - 5 k - 5

k - 5 k = -4 k:
Answer: k^2 - 4k - 5

Sum =F x (1 - R^N) / (1 - R), where F=First term, R=Common ratio, N=Number of terms.

nth. term =F x R^(N - 1), where F, R and N are the same as above.
