A. determine the number of different license plates that can be created using the following format. assume that a license plate consists of seven alphanumeric characters using numbers (0–9) and capital letters (a–z). find how many unique license plates can be printed using any of the 36 alphanumeric characters without duplication in each of the seven alphanumeric characters, i. e., no alphanumeric character appears more than once in any license plate. (this question is not related to your state’s license plates in the initial 3 parts above).

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 > ?
