Answer:

Step-by-step explanation:

\frac{ \sin(x) \csc(x) }{ \cot(x) }

cot(x)

sin(x)csc(x)

Rewrite csc(x) in terms of sin

\frac{ \sin(x) \frac{1}{ \sin(x) } }{ \cot(x) }

cot(x)

sin(x)

sin(x)

1

Multiply the numerator. Notice that the factors in the numerator are reciprocal so they will factor out to 1.

\frac{1}{ \cot(x) }

cot(x)

1

Notice that cotangent and tan are reciprocal so

\tan(x) = \tan(x)tan(x)=tan(x)

Step-by-step explanation:

\frac{ \sin(x) \csc(x)  }{ \cot(x) }

Rewrite csc(x) in terms of sin

\frac{ \sin(x) \frac{1}{ \sin(x) }  }{ \cot(x) }

Multiply the numerator. Notice that the factors in the numerator are reciprocal so they will factor out to 1.

\frac{1}{ \cot(x) }

Notice that cotangent and tan are reciprocal so

\tan(x)  =  \tan(x)

BRAINLIEST<br>through: (-3,5) parallel to y=-2x-3
umka2103 [35]

Answer:

Parallel Lines have the SAME SLOPE

We first Find the Slope of the line  

y = 2 x + 3

The Slope Intercept Form of the equation of a given line is:

y = m x + c

where  m  is the Slope of that line, and  c  is the Y intercept. For this line, the Slope is  2  So the Slope of the line PARALLEL to  

y = 2 x + 3

will also be  2 . And we are given that it passes through the point  

( − 3 , 4 )  

With this, we can use the Point Slope form to find the equation of the line.  

The Point-Slope form of the Equation of a Straight Line is:

( y − k ) = m ⋅ ( x − h )  m  is the Slope of the Line  

( h , k )  are the co-ordinates of any point on that Line.  

Here, we have been given the coordinates  

( h , k )  of 1 point on that line as  ( − 3 , 4 )  

And the Slope  m  is  2

Substituting the values of  h , k and m  in the Point-Slope form, we get

( y − 4 ) = ( 2) ⋅ ( x − ( − 3 ) )

The above will be the Equation of the Line in Point-Slope form.

If we need it in the Slope Intercept Form, we need to follow these steps:

Modifying the equation, we get:

( y − 4 ) = 2 ⋅ ( x + 3 )  

y − 4 = 2 x + 6

y = 2 x + 6 + 4  

We get the equation of the line as :

y = 2 x + 10

Hello,

I suppose you want the 4 numbers.

Let's call the numbers 2n,2n+2,2n+4,2n+6
2n+2n+2+2n+4+2n+6[=8n+12=15*4\\&#10;8n+12=60\\&#10;8n=48\\&#10;n=6\\\\&#10;2n=12\\&#10;2n+2=14\\&#10;2n+4=16\\&#10;2n+6=18\\&#10;
