The number of bachelor's degrees conferred has been increasing steadily in recent decades. The rate of change of the number of bachelor's degrees (in thousands) can be approximated by the following function where t is the number of years since 1970. B'(t) = 0.0651t- 1.116t + 14.55 Complete parts a. and b. below. a. Find B(t), given that about 865,200 degrees were conferred in 1970 (t=0).
