fgiga [73]

Part A:

Given that a bag contains 10 white golf balls and 6 striped golf balls, the ratio of white to striped golf balls is 10 : 6 = 5 : 3.

Given that a golfer wants to add 122 golf balls to the bag, the of balls each he should add is given by:

$5\left( \frac{122}{5+3} \right) \ : \ 3\left( \frac{122}{5+3} \right)=5\left( \frac{122}{8} \right) \ : \ 3\left( \frac{122}{8} \right) \\ \\ =5(15.25) \ : \ 3(15.25)=76.25 \ : \ 45.75 \\ \\ \approx76:46$

Therefore, the golfer shold add 76 white golf balls and 46 striped golf balls.

Part B.

You did not indicate the scale factor.

Assuming the scale factor is given by D(o, k) where k can be any number, then the cordinate of the coordinates of the image of the quadrilateral VWXY are given by:

V'(6k, 2k), W(-2k, 4k), X(-3k, -2k), Y(3k,-5k)

That is you multiply the scale factor to the coordinates of the preimage to get the coordinates of the image.

The annual revenue of Amazon.com rose from approximately $10.7 billion in 2006 to $34.2 billion in 2010. Use this information to

Sati [7]

1) Linear model

R(t) = y = at + b

Where t is the year - 2000 (year since 2000)

For year 2006, t = 6; for year 2010, t = 10

Then:

1) 10.7 = a*6 + b
2) 34.2 = a*10 + b

Subtract (1) from (2)

34.2 - 10.7 = 10a -6a

23.5 = 4a

a = 23.5/4 = 5.875

Now from (1) 10.7 = 6a + b => b = 10.7 - 6a = 10.7 - 6*5.875 = - 24.55

Then the resulting model is R(t) = 5.875a - 24.55

2) Exponential model

R(t) = A[B]^t

(1) 10.7 = A[B]^6
(2) 34.2 = A[B]^10

Divide (2) by (1)

[34.2/10.7] = [B]^10 / [B]^6

3.1963 = [B]^4 => B = 1.3371

Now, from (1) 10.7 = A [1.3371]^6 => A = 10.7 / [1.337]^6 = 1.8725

Then, the model is R(t) = 1.8725{1.3371]^t
