Recall that the height of an object t seconds after it begins moving when gravity is the only force acting on the object is given by
h(t)=−16t2+v0t+h0,
where h(t) is given in feet, v0 is the initial velocity of the object in ft/sec, and h0
is the initial height of the object in feet.
if a ball is thrown directly upward from the top of a building with an initial velocity of 60
feet per second, and an initial height of 75 feet. what is the maximum height attained by the ball?
your answer is feet.

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.
