Question

the cumlative number of car accidents from 2000 to 2010 can be modeled by the quadratic expression, C= 25x^2+600x+775-, where x=1 corresponds to 2000, x=2 corresponds to 2001, and so on until x=11 corresponds to 2010. Find the number of cumulative car accidents in 2003

Answer 1

In the year 2003, x =4.
\[C(4) = 25*4^{2} + 600*4 + 775 = 3575.\]
The cumulative number of deaths in 2003 was 3,575 deaths.
