Respuesta :
Using an exponential function, it is found that the number 131.5 represents the initial value of the plane, in thousands of dollars.
Exponential function:
A decaying exponential function is modeled by:
[tex]A(t) = A(0)(1 - r)^t[/tex]
In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem, the function for the value of the airplane after t years is given by:
[tex]A(t) = 131.5(0.8)^t[/tex]
Hence A(0) = 131.5, which means that the number 131.5 represents the initial value of the plane, in thousands of dollars.
