MATH133 Unit 1 Individual Project A1) The following graph shows the depreciation for the corporate airplane from 2006 to 2009. The plane was purchased new in 2006; therefore x = 0 represents the year 2006. X axis (horizontal) = years starting from 0 = 2006 and increasing by 0.5 years Y axis (vertical) = price in $ amounts from 24000 to 240000 a) List the coordinates of two points on the graph in (x y) form. The numbers on the horizontal axis are 0.5 1.0 1.5 2.0 2.5 3.0 and 3.5. (___ ___)(___ ___)b) Find the slope (rate of depreciation) of this line:c) Find the linear equation of this line in slope-intercept form.d) If the rate of depreciation continues at the present rate what will be the plane s value in the year 2019? Show how to use the linear equation from part c) to obtain your answer.2) Suppose that the width of a rectangle is 5 inches shorter than the length and that the perimeter of the rectangle is 80 inches. The formula for the perimeter of a rectangle is P=2L+2W. a) Set up an equation for the perimeter involving only L the length of the rectangle.b) Solve this linear equation algebraically to find the length of the rectangle. Find the width as well. 3) A marketing group developing online ad space is offering two payment options: Option 1: $225 set up fee plus $10/inch of the ad Option 2: No set up fee but $25/inch of the ad Let x = inches of the proposed ad for example x = 2 for a column ad that is 2 inches long. a) Write a mathematical model representing the total ad cost C in terms of x for the following: Option 1: C=_________________ Option 2: C=_________________b) How many inches of ad space would need to be purchased for option 1 to be less than option 2? Set up an inequality and show your work algebraically using the information in part a).4) Graph the equations on separate graphs by completing the tables and plotting the points. You may use Excel or another web-based graphing utility. a) Complete the table using the given values of x and the equation y = -3x + 7. b) Graph the equation here by plotting the points from your table.For help oncreating your graph in Excel and inserting graphs into a Word Doc please see thetutorial in the Assignment List.
