The first condition is for the perimeter of the equation so:
Now the secon condition is that the sum of two sides should be:
so the negative option and 0 don't make sence dor a distance, then we try with the value of b=0.5
So in the first equation will be:
So the condition:
this is false, so the solution is
The exponential equation that models this situation is:
.
A decaying exponential function is modeled by:
In which:
For this problem, the parameters are:
A(0) = 18000, r = 0.15.
Hence the equation for the value of the car over the next 5 years is:
.
