Answer:
The correct answer is <u>$10,629</u>
Step-by-step explanation:
Here is how I got it!
First, you will have to borrow the 20,000 from the word problem.
Next, multiply <u>20,000 with 0.81 with the power of 3</u>
<u /><u />
The 3 is the number of years, n is the nearest $ answer.

First, do
(Wow, that's a crazy number!)
--
With 0.531441, multiply it with 20,000
10,628.82 is technically (in money) $10,628.82 (with .82 being eighty-two cents).
--
Finally, it states to answer to the <u>nearest</u> $.
Just round up the .82 to 1 dollar which will just add one more dollar to 10,628
⇒
Add you $ symbol
With the result being: $10,629
It’s the letter c

A] The most likely value of the correlation function for the data is -0.04, this i because the relationship between the two variables time and velocity do not how a strong linear relationship between them.
Part B:
The value of the slope between times 10 min and 20 min will be:
slope, m=(y-y1)/(x-x1)
thus taking points (10,0.2) and (20,0.8)
slope,m=(0.8-0.2)/(20-10)=0.6/10=0.06 miles/ min²
c] The relationship will be described as causation/ causality because time is partly responsible for the velocity of the toy and velocity is partly dependent on time.
