Select the correct answer from each drop-down menu. John is preparing to retire, and he knows he'll receive a pension from his
company. The pension will pay John $25,000 per year
for 20 years. A lump-sum payment of $500,000 today is also an option for John, and the account John would use for that money
would pay interest of 3% per year, compounded annually.
Since the present value of all the yearly pension payments is
John should choose the
option for his pension.

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 > ?
