O is the origin.
ABCDEF is a regular hexagon and O is the midpoint of AD.

Vector OA = a
Vector OC = c

Find, in terms of a and c, in their simplest form . . .
a) . . . vector BE.
b) . . . vector DB.
c) . . . the position vector of E.

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.
