Determine the ratio of the directed line segment AB when partitioned by point P. (Hint: A is the initial point) A B The ratio is [ Select ] : [ Select ]

Use the cross product to find the area of the triangle with the vertices P = (3, 3,7), Q = (5,6, 5), and R = (3,7,9) in the figure R (Use symbolic notation and fractions where needed.) A =

Let s be a person's annual salary (in thousands of dollars) after she has worked for t years at a company. Some pairs of values of t and s are shown in the table below. t (years) 0 1 3 6 s (thousands of dollars) 54 57 63 72 a) Create a scattergram of the data. b) Draw in a linear model on the same grid. c) Use your graph to estimate when the person's salary will be $66 thousand. (Show your work on the graph.) d) What is the s-intercept of the model? Interpret it in terms of this application.

Match these values of r with the accompanying scatterplots: 0.465, - 0.465, - 0.797, 1, and 0.797. Click the icon to view the scatterplots. Match the values of r to the scatterplots.
