Answer:

Step-by-step explanation:

Coupon A

Unit price of fresh buns = \frac{\text{Total price}}{\text{Number of buns in a pack}}

                                        = \frac{3.24}{12}

Unit Price = $0.27 per bun

Coupon B

Units price of fresh buns = \frac{4.5}{18}

Unit Price = $0.25 per bun

Coupon with the better buy is Coupon B.

Coupon C

Unit price of hamburger meat = \frac{\text{Price}}{\text{Quantity}}

                                                  = \frac{5.44}{16}

                                                  = $0.34 per hamburger

Coupon D

Unit price = \frac{9.6}{24}

                = $0.40 per hamburger

Coupon with better buy is Coupon C.

What is the value of cos θ given that (-2, 9) is a point on the terminal side of θ?
liq [111]

Answer:

a)  cosθ  = \frac{-2\sqrt{85} }{85}

Step-by-step explanation:

<u><em> Step(i):</em></u>-

Given point ( x , y ) = ( - 2 , 3 )

We know that the polar co-ordinates

  x = r cos θ and y = r sinθ

where   r = \sqrt{x^{2} +y^{2} }  

            r = \sqrt{(-2)^{2} +(9)^{2} } = \sqrt{4+81} = \sqrt{85}

<u><em>Step(ii)</em></u>:-

           x = r cos θ

          cosθ   = \frac{x}{r}

      cosθ  = \frac{-2}{\sqrt{85} } = \frac{-2}{\sqrt{85} } X \frac{\sqrt{85} }{\sqrt{85} }

       cosθ  = \frac{-2\sqrt{85} }{85}
