Linear Algebra
To fit data to an exponential model like y = AeKt, we first use a logarithm to linearize it: . n y n A k t Since A is a constant, so is ln A, and we can write this generically as ln y = co + cit. The table below shows the years different planes were first produced, along with how many displays (gauges, screens, etc.) were present in the cockpit. Year Introduced, y (Year after 1900)...

4. Consider the following data. 16 74 900 29810 (a) Suppose you would like to fit a model of the form yCes (C and k are constants) to this data. Transform the model in such a way that you can use linear least squares to determine C and k. (b) For this data set, use the following equations to find a best fit line. and (e) Use your calculation from part b) to find the model y - Cek for...
