samâs auto shop services and repairs a particular brand of foreign automobile. sam uses oil filters throughout the year. the shop operates fifty-two weeks per year and weekly demand is 150 filters. sam estimates that it costs $20 to place an order and his annual holding cost rate is $3 per oil filter. currently, sam orders in quantities of 650 filters. calculate the total annual costs associated with samâs current ordering policy
total annual costs = $

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α. part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i. e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
