The surface of a pedestrian bridge forms a parabola. Let the surface at one side of the bridge be represented by (6,0) and the surface at the other side be represented by (14,0). The center of the bridge is 2 feet higher than each side and can
be represented by a vertex of (10,2). Write a function in vertex form that models the surface of the bridge.

17. a researcher measures three variables, x, y, and z for each individual in a sample of n = 20. the pearson correlations for this sample are rxy = 0.6, rxz = 0.4, and ryz = 0.7. a. find the partial correlation between x and y, holding z constant. b. find the partial correlation between x and z, holding y constant. (hint: simply switch the labels for the variables y and z to correspond with the labels in the equation.) gravetter, frederick j. statistics for the behavioral sciences (p. 526). cengage learning. kindle edition.
