Answer:

A.\,\orange{ \bold{ \frac{x - 3}{3x + 1} }}

Step-by-step explanation:

\frac{x + 2}{ {x}^{2} + 5x + 6 }  \div  \frac{3x + 1}{ {x}^{2}  - 9}  \\  \\  = \frac{x + 2}{ {x}^{2} + 3x  + 2x+ 6 }  \div  \frac{3x + 1}{ {x}^{2}  -  {(3)}^{2} }  \\  \\  = \frac{\cancel{x + 2}}{ \cancel{{({x}+ 3)}} \cancel{(x+ 2) }}   \times   \frac{\cancel{( {x}  +   3)}( {x} -  {3)}}{3x + 1}  \\  \\  =  \purple{ \bold{ \frac{x - 3}{3x + 1} }}

Verifying Trig Functions
anzhelika [568]

Answer:

The answer to your question is below

Step-by-step explanation:

                csc α - cot α = \frac{sin \alpha }{1 + cos \alpha }

Work with the left part

                \frac{1}{sin\alpha } - \frac{cos \alpha }{sin \alpha}

Simplify

                \frac{1 - cos\alpha }{sin\alpha }

Multiply by the reciprocal

 \frac{1 - cos\alpha }{sin \alpha } x \frac{1 + cos\alpha }{1 + cos\alpha }                                  

Simplify

\frac{1 - cos^{2}\alpha}{sin\alpha (1 + cos\alpha)}

Remember that

                 sin²α = 1 -cos²α

Substitute the previous equation

\frac{sin^{2}\alpha }{sin\alpha(1 + cos\alpha ) }

Simplify

\frac{sin\alpha}{1 + cos \alpha}      

The identity i proved.

Can u plz help me look at the photo<br><br> PLZ NO LINKS
djyliett [7]

Answer:

0.07

Step-by-step explanation:

The hundredths place is the place between the tenths and thousandths place. For example, the digit in the tenths place in 0.073 is 7.

To round to the nearest hundredth, we look to the digit right of the hundredth digit, 7. We notice that the digit in the thousandths place is 3. When rounding, if a number is 4 or less, we change that digit to a 0, along with the digits beyond it. If a number is 5 or more, we bump up the digit to the next number. Since 3 is less than 4, we change 0.073 to 0.07.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
