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:
2 x 7 x 3²
Step-by-step explanation:
When finding primes, you use the method I attatched as a picture. Start with the large number at the top, slowly dividing it by factors of it.
The picture shows that the primes 126 is a product of is:
2, 7, 3, 3
Or:
2 x 7 x 3 x 3
This can be simplified into:
2 x 7 x 3²
Hope this helps!
Answer:
x = (y+w)/k
Step-by-step explanation:
xk-w=y
Add w to each side
xk-w+w=y+w
xk = y+w
Divide each side by k
xk/k = (y+w)/k
x = (y+w)/k
Ok, find change then divide by years elapsed
change=310-280 million=30 million
number of years elapsed=10
30mil/10=3mil
3million per year was the population growth rate
