19. A growing field of inquiry that both holds great promise and poses great risk for humans is nanotechnology, the construction of extremely small machines. Over the past couple of decades, the size that a working gear can be made has consistently gotten smaller. The table shows milestones along this path Years from 1967 0 7 16 25 31 37 Minimum gear size [mm] 0.8 0.4 0.2 0.090.007 2E-04 8E-06 a. Create a proper plot of the gear size (ordinate) versus the number of years from 1967 assuming the data are experimental b. Use polyfit to determine the exponential relationship for the data set and graph the resulting trendline along with the experimental data
