4. Writing to Explain A marching band practices 5 h for every 30 min they perform. What fraction of their playing time is spent performing? Draw a picture
to solve. Explain how to use your picture to find how many hours the band
performs if they play 22 hours. Solve the problem as part of your explanation.
HINT: YOU CAN DOUBLE THE TIME SPENT ON EACH ACTIVITY TO SOLVE.

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 > ?
