Micheal Redkin and Math Basics :: essays research papers

In ordering to make water a represent such as the one Ms. Redkin aims to aim the depreciation of her lease place, first it must be determined which vocalism of the information attached is the dependant variable and which is the independent variable. In this oddball the independent variable is time (in geezerhood), and the dependent the think of of the mansion. Next create a interpret with the given data, the independent variables on the x-axis and the dependent on the y.Graph and label the given data as points (4 yrs, $64000) and (7 yrs, $52000), allow the graph to represent the phratrys value from when it was new to 10 courses after its purchase. Graph a line from these two points, now you may follow the line to find the approximate value of the house at certain years of depreciation. In order to find the value of the rental house after ten years, follow the line previously graphed to 10 on the x-axis. The y value you should receive should be 40,000, and if you wer e searching for the value of the house when it was new, the graph shows $80,000 at 0 years. Anformer(a) example of how this graph may be used is in finding which year the house reaches a certain value. In order to find out which year the houses value becomes 55,000 follow the graphed until you come upon the value of 55,000. The x value associated with the value 55,000 is 5 years, so the answer is the rental house volition depreciate in value to 55,000 at 5 years.The slope of the line will be required to find many other answers to questions you may have concerning the house and its depreciation. To determine the slope of the line,use the given points of (4,64000) and (7,52000) in the equation (y2-y1)/(x2-x1), that is determine the change in y divided up by the change in x which is the slope. (52000-64000)/(7-4) is the specific equation we will enquire for this line, the solution, -4000 is the slope of the line once simplified. One way to use the slope is to formulate an equation which will relate the value of the house to the number of years depreciated. Let V stick out for the value, and t stand for the number of years it has been depreciated. To complete this equation we will also need to know the y intercept so we may use the
