Births and Deaths From 2008 to 2012, the total numbers of births B (in thousands) and deaths D (in thousands) in the United States can be approximated by the models B ( t ) = 4.917 t 3 − 124.71 t 2 + 925.9 t + 2308 and D ( t ) = − 7.083 t 3 − 222.64 t 2 + 2281.8 t + 10 , 104 where t represents the year, with t = 8 corresponding to 2008. Find B ( t ) − D ( t ) and interpret this function. ( Source: U.S. National Center for Health Statistics )

Question 2
Let F be a solenoidal vector field, suppose V × F = (-8xy + 12z², −9x² + 4y² + 9z², 6y²), and let
(P,Q,R) = V²F(.725, —.283, 1.73). Then the value of sin(2P) + sin(3Q) + sin(4R) is
