Locate the lowest and highest points on your graph. what is the amplitude? there are 365 days in a year. explain this value's relationship to the graph. what is the vertical shift of the graph? what is the phase shift of the graph? write a sinusoidal function that models the number of daylight hours for the year in this city. using your equation, estimate the number of daylight hours in this city on the 220th day of the year. based on your graph, does this answer seem reasonable? explain any discrepancy that might

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 > ?
