1. Create a surface plot of F(x,y)=sin({(x/4)2+(y/9)2}) for 8x8 and 8y8. Use 0.5 as increment, i.e. x=8,7.5,7.7,7.5,8 2. Create an Excel table containing the data shown below: (a) Sort the data from smallest to largest. (b) Plot the sorted discrete data (use X-Y Scatter chart type). (c) Draw a 3rd order polynomial trendline though the data, and show the trendline equation on the graph. (d) Using the trendline equation estimate how many cars someone who has been working for 8 weeks can be expected to inspect? (Note they can only inspect whole cars, no fractions. So use ROUNDO function for final answer.) 3. Create an Excel table containing the data shown below (use copy and paste to Excel) (a) Convert the distance from inch to meter (use CONVERTO function) (b) Plot the discrete data set Air Velocity (m/s) vs. Distance (m) (note distance is in meters and is plotted on the horizontal axis of a X Y Scatter chart). (c) Draw an exponential trendline through the data set, and show the trendline equation on the graph
