Answer:
Step-by-step explanation:
- Initial value = $500000
- Depreciation rate = 5.41% each year
- Target value = 1/2*$500000 = $250000
- Number of years = x
Depreciation can be expressed as function:
- d(x) = 500000*((100 - 5.41)/100)^x
- d(x) = 500000*0.9459^x
Having the final value of $250000, we can find x:
- 250000 = 500000*0.9459^x
- 0.5 = 0.9459^x
- log 0.5 = x log 0.9459
- x = log 0.5 / log 0.9459
- x = 12.46 ≈ 13 years rounded
8/x -5/x=4
multiple x on both side
8-5=4x
3=4x
x=3/4
2120 acres* (13/100)= 275.6 acres.
275.6 acres of pine trees still remains today~
Answer:
3x+5=3x+5
they are both the same line
