Answer:
5
Step-by-step explanation:
The values of BMW after 2 years and 4 years according to the EXPONENTIAL FUNCTION are $33,462 and $20,358.28
Using the parameters given, we define an decreasing exponential function :
![A = A_{0} (1 - r)^{t}](https://tex.z-dn.net/?f=A%20%3D%20A_%7B0%7D%20%281%20-%20r%29%5E%7Bt%7D)
Where,
= initial amount ; r = Rate ; t = time ; A = final amount
Value after 2 years :
t = 2
A = 55000(1 - 0.22)²
A = 55000(0.78)²
A = $33,462
Value after 4 years :
t = 4
A = 55000(1 - 0.22)^4
A = 55000(0.78)^4
A = $20,358.28
Therefore, the value of BMW after 2 years and 4 years $33,462 and $20,358.28 respectively.

Answer:
![x > 16](https://tex.z-dn.net/?f=x%20%3E%2016)
Step-by-step explanation:
![- \frac{3}{8} x -20+2x>6](https://tex.z-dn.net/?f=%20-%20%5Cfrac%7B3%7D%7B8%7D%20x%20-20%2B2x%3E6)
Add 20 to both sides:
![- \frac{3}{8} x + 2x > 26](https://tex.z-dn.net/?f=%20-%20%20%5Cfrac%7B3%7D%7B8%7D%20x%20%2B%202x%20%3E%2026)
Multiply 8 on both sides:
![- 3x + 16x > 208](https://tex.z-dn.net/?f=%20-%203x%20%2B%2016x%20%3E%20208)
![13x > 208](https://tex.z-dn.net/?f=13x%20%3E%20208)
Divide by 13 on both sides:
![x > 16](https://tex.z-dn.net/?f=x%20%3E%2016)
