4. An amusement park developed a program for local fifth grade students to study the
relationship between angles and forces and motion of roller coasters.
. The park created the program to serve up to 4,050 students.
. The park has confirmed 185 students from 14 schools will attend the program.
How many more students can be invited to participate in the program?
A 1,460
B 1,560
C 2,460
D 2,590

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 > ?
