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

Answer:
1.91/9
Step-by-step explanation:
x=0.212121212........ .........1 equation
10x=2.12121212......... ........2 equation
1 equation - 2 equation
9x=1.91
x=1.91/9
therefore 0.212121.....=1.91/9
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.
