Give a formula F ( x , y ) = M(x, y) i + N(x, y) j for the vector field in a plane that has the properties that F = 0 at (0, 0) and that at any other point (a, b). F is tangent to circle x 2 + y 2 = a 2 + b 2 and points in the clockwise direction with magnitude | F | = a 2 + b 2 .

Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
A school counselor is conducting a research study to examine whether there is a relationship between the number of times teenagers report vaping per week and their academic performance, measured by GPA. The counselor collects data from a sample of high school students. Write the null and alternative hypotheses for this study. Clearly state your hypotheses in terms of the correlation between vaping frequency and academic performance.
