Using an exponential function, it is found that it takes 5.42 years for the car to halve in value.
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem, the car depreciates 12% a year in value, hence r = 0.12 and the equation is given by:
.
It halves in value at t years, for which A(t) = 0.5A(0), hence:
t = 5.42.
It takes 5.42 years for the car to halve in value.

Answer:
The First Table
Step-by-step explanation:
The y-values increase inconsistently, while the other tables are constant.
Answer: A = 112km^2
Explanation:
A = L x W
A = 14km x 8km
A = 112km^2
The value of x would be 24 because all the sides added up must equal 72
Answer:
or
Step-by-step explanation:
The given quadratic function is
To find the roots, we set f(x)=0 to get:
The solution is given by:
where a=8, b=-16, c=-15
We substitute to get:
We simplify to get:
