Answer:

x = 9

Step-by-step explanation:

Given

3x - $\frac{1}{5}$ - $\frac{2}{9}$ x = $\frac{124}{5}$ ( add $\frac{1}{5}$ to both sides

3x - $\frac{2}{9}$ x = $\frac{124}{5}$ + $\frac{1}{5}$ = $\frac{125}{5}$ = 25 ← combine x- terms on left side

$\frac{25}{9}$ x = 25 ( multiply both sides by 9 )

25x = 225 ( divide both sides by 25 )

x = 9

Prove that sinxtanx=1/cosx - cosx

maks197457 [2]

Answer:

See below

Step-by-step explanation:

We want to prove that

$\sin(x)\tan(x) = \dfrac{1}{\cos(x)} - \cos(x), \forall x \in\mathbb{R}$

Taking the RHS, note

$\dfrac{1}{\cos(x)} - \cos(x) = \dfrac{1}{\cos(x)} - \dfrac{\cos(x) \cos(x)}{\cos(x)} = \dfrac{1-\cos^2(x)}{\cos(x)}$

Remember that

$\sin^2(x) + \cos^2(x) =1 \implies 1- \cos^2(x) =\sin^2(x)$

Therefore,

$\dfrac{1-\cos^2(x)}{\cos(x)} = \dfrac{\sin^2(x)}{\cos(x)} = \dfrac{\sin(x)\sin(x)}{\cos(x)}$

Once

$\dfrac{\sin(x)}{\cos(x)} = \tan(x)$

Then,

$\dfrac{\sin(x)\sin(x)}{\cos(x)} = \sin(x)\tan(x)$

Hence, it is proved

Convert 8.132132132 ... to a rational expression in the form of a over b , where b ≠ 0. (4 points)

Butoxors [25]

8 would become the whole number, since there are 3 repeating numbers you would put those over 999.

So you would get 8 and 132/999
