Combine as indicated by the signs. 4/ y^2-9 + 5/y+3
natka813 [3]
\frac{4}{y^{2}-9 } + \frac{5}{y+3} = \frac{4}{(y-3)(y+3) } + \frac{5}{y+3}= \frac{4}{(y-3)(y+3) } + \frac{5(y-3)}{(y-3)(y+3)}=
\\ \\=\frac{4}{(y-3)(y+3) } + \frac{5y-15}{(y-3)(y+3)}= \frac{5y-11}{(y-3)(y+3)}=\frac{5y-11}{y^{2}-9}

Annual insurance is 1,000 face value.
satela [25.4K]

Answer:

The correct answer is A.

Step-by-step explanation:

  • Premium for Company A :

face value = 1.86 , charges are 20% more for smokers

⇒ Charges = 20% of 250000 = $50000

Total charge = Charge × face value

                     = 50000 × 1.86 = $93000

  • Premium for Company B :

face value = 1.86 , charges are 18% more for smokers

⇒ Charges = 18% of 250000 = $45000

Total charge = Charge × face value

                     = 45000 × 1.86 = $83700

  • Premium for Company C :

face value = 2.07 , charges are 25% more for smokers

⇒ Charges = 25% of 250000 = $62500

Total charge = Charge × face value

                     = 62500 × 2.07 = $129375

  • Premium for Company D :

face value = 2.25 , charges are 15% more for smokers

⇒ Charges = 15% of 250000 = $37500

Total charge = Charge × face value

                     = 37500 × 2.25 = $84375

Hence, The option A. is correct that is Aaron is paying the smallest premium possible with company B

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.
