Question 125465: From 1990 to 1993, the number of truck registrations (in millions) in the united states can be approximated by the model R=0.29t^2+45 where t is the number of years since 1990. During which year were approximately 46.16 million trucks registered. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! From 1990 to 1993, the number of truck registrations (in millions) in the united states can be approximated by the model R=0.29t^2+45 where t is the number of years since 1990. During which year were approximately 46.16 million trucks registered.
--------------------
46.16 = 0.29t^2+45
0.29t^2 = 1.16
t^2 = 4
Positive solution:
t = 2 years.
