Thomas measured the amount of rain that fell during a particularly rainy day in Louisiana. He measured the rain every hour over the course of a few hours. Rain is usually measured in millimeters by meteorologists, so Thomas decided that he would use the same unit of measurement. After his final measurement, the total amount of rain that fell was 50 mm. Part A. Create a function that Thomas can use to represent the total amount of rain that fell, A, as a function of time in hours, h. Part B. Use function notation to represent the following statements: (i) Five hours after Thomas began measuring the rain, the amount of rain was 4 centimeters. (ii) The amount of rain collected 150 minutes after he started measuring was the same amount as his measurement after 180 minutes.

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 > ?
