Problema Solution
The retail space in shopping centers in the united states from 1990 to 2003 can be modeled by S=-0.076t^3+1.053t^2+110.937t+4423 where S is the amount of retail space (in millions of square feet) and t is the number of years since 1990. Graph the model. How much retail space will there be 2011?
Answer provided by our tutors
In 2011, t = 21
S(21) = -0.076(21)^3+1.053(21)^2+110.937(21)+4423 = 6513.2
So there will be 6513.2 retail space
