Answer:

<h3>Car A</h3>
  • Initial price = $30000
  • Initial depreciation = 20%
  • Further yearly depreciation = $2000

<u>The equation to reflect the above:</u>

  • A(t) = 30000 - 0.2*30000 - 2000t ⇒
  • A(t) = 24000 - 2000t
<h3>Car B</h3>
  • Initial price = $25000
  • Initial depreciation = 10%
  • Further yearly depreciation = $1500

<u>The equation to reflect the above:</u>

  • B(t) = 25000 - 0.1*25000 - 1500t ⇒
  • B(t) = 22500 - 1500t

29 If we round to 1 significant figure, sound travels at a speed of approximately 0.3 kilometers per second, while light travels
MrRissso [65]

Answer:

3 x 10^-1 km per second.

Step-by-step explanation:

A scientific notation includes c x 10^n. c is a number between 1-9, and n is the nth power of 10.

If we move the decimal in 0.3 to the right by 1 place, we can get "c", which will be 3. Since we have moved the decimal to the right, each place moved right counts as -1 for n.

So, the answer is 3 x 10^-1 km per second.
