Answer:
V (t) = 28,900 - 4,335t
The function clearly represent a decay
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Value of the car = $ 28,900
Annual depreciation = 15% = 0.15
2. Identify the function for the value of the car. Does the function represent growth or decay?
Let y represent the value of the car after t years of utilization, let p the price of the car and d, the annual depreciation, therefore:
V (t) = p - (d * t * p)
Replacing with the values we know:
V (t) = 28,900 - (0.15 * t * 28.900)
V (t) = 28,900 - (0.15 * t * 28.900)
V (t) = 28,900 - 4,335t
The function clearly represent a decay.
The function for the value of the car is [tex]v(t)=28900(0.85)^t[/tex], where [tex]t[/tex] is the time in years. It is a decay function.
It is given that,
- The initial value of the car is $28900
- Decreasing rate is 15% per year.
Explanation:
The value of car after [tex]t[/tex] years is:
[tex]v(t)=a(1-r)^t[/tex]
Where, [tex]a[/tex] is the initial value and [tex]r[/tex] is the decay rate.
The value of car is:
[tex]v(t)=28900(1-0.15)^t[/tex]
[tex]v(t)=28900(0.85)^t[/tex]
Thus, the required function is [tex]v(t)=28900(0.85)^t[/tex] and it is a decay function because growth factor 0.85 is less than 1.
