The tide is the regular rising or falling of the ocean’s surface. This is due in large part to the gravitational forces of the moon. The following table represents water level of the tide off the coast of Kings Point, N. Y., for a 24 hour period, February 9th through February 10th of 2009. Hour Measurement in feet above the average low tide 0 -0.98 2 5.83 4 7.78 6 7.34 8 2.33 10 -0.47 12 -0.21 14 5.32 16 8.83 18 8.31 20 3.80 22 -0.28 24 0.53 Plot the data points given in the table using hour as the independent variable. Does this data indicate that a sine regression may be appropriate in this case? Explain. a. Yes, in the scatterplot the wavelike behavior is apparent although not precise. b. Yes, the scatterplot shows an increase over time. c. No, there is no correlation between the points. d. No, the scatterplot depicts a hyperbole.

Part a what is the area of triangle i? show your calculation. part b triangles i and ii are congruent (of the same size and shape). what is the total area of triangles i and ii? show your calculation. part c what is the area of rectangle i? show your calculation. part d what is the area of rectangle ii? show your calculation. part e rectangles i and iii have the same size and shape. what is the total area of rectangles i and iii? show your calculation. part f what is the total area of all the rectangles? show your calculation. part g what areas do you need to know to find the surface area of the prism? part h what is the surface area of the prism? show your calculation. part i read this statement: “if you multiply the area of one rectangle in the figure by 3, you’ll get the total area of the rectangles.” is this statement true or false? why? part j read this statement: “if you multiply the area of one triangle in the figure by 2, you’ll get the total area of the triangles.” is this statement true or false? why?
