Question 1184500: in 1998, the sports league introduced a salary cap that limits the amount of money spent on players’ salary. the quadratic model y=0.2313x^2+2.600x+35.17 approximates this cap in millions of dollars for the years 1998-2012, where x=0 represents 1998, x=1 represents 1999, and so on. complete parts a and b.
a) approximate the sports league salary cap in 2008.
b) according to the model, in what year did the salary cap reach 95 million dollars?

y=0.2313x^2+2.600x+35.17
x=10 in 2008
so y=23.13+26+35.17=$84.31 million.
-
95=0.2313x^2+2.600x+35.17
or y 0.2313x^2+2.600x-59.83
y=(1/0.4626)(-2.600+sqrt(6.76+55.354)); sqrt term=7.88
y=11.42 years
this would be 2010.
