- 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. (b) Identify the vector operation used to increase wages by 2arrow_forwardError Analysis Describe the error in finding the component form of the vector u that has initial point 3,4 and terminal point 6,1. The components are u1=36=9and u2=41=5. So,u=9,5.arrow_forwardWriting How could you describe vector subtraction geometrically? What is the relationship between vector subtraction and the basic vector operations of addition and scalar multiplication?arrow_forward
