Linear Algebra Question
25. Suppose you are looking at data which is supposed to fit an exponential equation, i.e. a model of the form y= Cekz where C and k are constants. Suppose your data points are (2, 5), (3,8) and (4, 17). Use least-squares to find (decimal approximations to) the values of C and k which best fit this model How to proceed: First, take the natural log of both sides of the model to obtain what is called...

1. Suppose you are stranded on a desert island and do not have access to a computer, calculator, cell phone, or even a slide rule! Suppose that you find an old treasure map with the following table: n 1 2 3 4 5 6 7 8 9 10 ln n 0.00 0.69 1.10 1.39 1.61 1.79 1.95 2.08 2.20 2.30 where ln is taken to mean the natural log. Using only this table, compute the following: (a) ln 20 (b)...
