Simplify please and show steps:<br><br> Sec (x) tan (x) csc (x) cot (x) sin (x) cos (x)

Airida [17]

Answer:

<h2>The answer is 1</h2>

Step-by-step explanation:

First of all transform the expression using trigonometric identities

That's

$\sec(x) = \frac{1}{ \cos(x) }$

$\csc(x ) = \frac{1}{ \sin(x) }$

$\cot(x) = \frac{1}{ \tan(x) }$

So we have

$\frac{1}{ \cos(x) } \times \tan(x) \times \frac{1}{ \sin(x) } \times \frac{1}{ \tan(x) } \times \sin(x) \times \cos(x)$

Reduce the expression with tan x

We have

$\frac{1}{ \cos(x) } \times \cos(x) \times \frac{1}{ \sin(x) } \times \sin(x)$

Reduce the expression with cos x

That's

$1 \times \frac{1}{ \sin(x) } \times \sin(x)$

Reduce the expression with sin x

We have

$1 \times 1$

We have the final answer as

Hope this helps you

m_a_m_a [10]

Equation of a line is given by y = mx + b; where m is the slope and b is the y-intercept.
In the given equation, y = -13x + 56k; b = -10
56k = -10
k = -10/56 = -5/28

Please help 50 points!<br> Simplify the expressed

LenKa [72]

Answer:

Step-by-step explanation:

$\frac{x^{2} -x-12}{x+4} * \frac{2x^{2}-32 }{x^{2} -8x+16}$ rewrite as multiplication

$\frac{x^{2} +3x-4x-12}{x+4} * \frac{2(x^{2}-16) }{x^{2} -8x+16}$ look to factor

$\frac{x(x+3)-4(x+3)}{x+4} * \frac{2(x-4)(x+4) }{(x-4)^{2}}$ , difference of 2 squares and perfect square

$\frac{(x+3)(x-4)}{x+4} * \frac{2(x-4)(x+4) }{(x-4)^{2}}$ , finish factoring and simplify
