A cyclist is riding from the city to the country. She rides 20 miles each hour. At the
beginning of the 1st hour, she is 10 miles
away from the city center. At the beginning of
the 2nd hour, she is 30 miles away from the
city center. Write an explicit formula to show
her distance from the city at any given hour.
Then use the formula to find her distance at
the beginning of the 5th hour.

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 bsuppose 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 cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
