- Business The vector u=1225,2445 gives the numbers of hours worked by employees of a temporary work agency at two pay levels. The vector v=12.20,8.50 gives the hourly wage (in dollars) paid at each level, respectively. (a) Find the dot product uv and interpret the result in the context of the problem.
