A van is purchased new for $29,200 . a. Write a linear function of the form y = m t + b to represent the value y of the vehicle t years after purchase. Assume that the vehicle is depreciated by $2920 per year. b. Suppose that the vehicle is depreciated so that it holds only 80 % of its value from the previous year. Write an exponential function of the form y = V 0 b t , where V 0 is the initial value and t is the number of years after purchase. c. To the nearest dollar, determine the value of the vehicle after 5 yr and after 10 yr using the linear model. d. To the nearest dollar, determine the value of the vehicle after 5 yr and after 10 yr using the exponential model.

Solution Summary: The author explains the linear function of the form y=mt+b and the exponential function.
a. Write a linear function of the form
y
=
m
t
+
b
to represent the value y of the vehicle t years after purchase. Assume that the vehicle is depreciated by
$2920
per year.
b. Suppose that the vehicle is depreciated so that it holds only
80
%
of its value from the previous year. Write an exponential function of the form
y
=
V
0
b
t
,
where
V
0
is the initial value and t is the number of years after purchase.
c. To the nearest dollar, determine the value of the vehicle after 5 yr and after 10 yr using the linear model.
d. To the nearest dollar, determine the value of the vehicle after 5 yr and after 10 yr using the exponential model.

2. A Delta airplane and an SouthWest airplane take off from an airport
at the same time. The bearing from the airport to the Delta plane is
23° and the bearing to the SouthWest plane is 152°. Two hours later
the Delta plane is 1,103 miles from the airport and the SouthWest
plane is 1,156 miles from the airport. What is the distance between the
two planes? What is the bearing from the Delta plane to the SouthWest
plane? What is the bearing to the Delta plane from the SouthWest
plane?
