From 1958 to 2018, the number of students S (in thousands) enrolled in United States public schools can be modeled by the function below where x is the number of years since 1958. \large S\left(x\right)=1.84x^3-201x^2+1910 x+69,800

1. Graph the function. Label axes and provide a title.
2. Identify any turning points on the domain 0 < x < 60. What real-life meaning do these points have?
3. What is the range of the function for the domain 0 < x < 60? What real-life meaning do these points have?

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 > ?
