Two companies company a and company b offer the same starting salary of $20,000 per year. company a gives a raise of $1000 each year. company b gives a raise of 4% each year.

a) write rules a and b in the nth year at companies a and b respectively.

b) for each company find the sum of wages earned during the first 20 years of employment

c) using the graphing calculator to find after how many years the total amount earned a company b is greater that the total amount of earned at company a?

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 > ?
