Mrs. chandler, the p. e. teacher, is pairing off students to race against each other. latrell can run 4 yards per second, and christopher can run 6 yards per second. mrs. chandler decides to give latrell a head start of 10 yards since he runs more slowly. once the students start running, christopher will quickly catch up to latrell. how far will christopher have to run? graph your answer

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 > ?

What is the approximate value of the correlation coefficient for the given graph? a. 1 b. 5 c. 3 d. -1
