Two scuba diving instructors charge money for each hour of work, plus a one-time fee for private lessons. Instructor Tommy charges according to this graph:

Instructor Bobby charges according to this table:
a) How much does Tommy cost for each hour of work, and what is his one-time fee? Show or explain your reasoning.

b) How much does Bobby cost for each hour of work, and what is his one-time fee? Show or explain your reasoning.

c) Can Tommy and Bobby every charge the same total for the same amount of time? Explain and show your reasoning.

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 bsuppose 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 cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
