The monthly profit for a small company that makes long-sleeve t-shirts depends on the price per shirt. if the price is too high,
sales will drop. if the price is too low, the revenue brought in may not cover the cost to produce the shirts. after months of data
collection, the sales team determines that the monthly profit is approximated by f(p) = -50p + 1800p - 16,000, where p is the
price per shirt and f(p) is the monthly profit based on that price.
(a) find the price that generates the maximum profit.
(b) find the maximum profit.
(c) find the price(s) that would enable the company to break even. if there is more than one price, use the "and" button.
solve all 3 parts.

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 > ?
