Define a main program and a function program 2. Main program a. define the vectors x, y, and the vector for the initial guess for a. Use your engineering judgment to come up with an appropriate initial guess vector for {a}. It should be fairly obvious what "ballpark" initial guesses should be for a1 and a3, but a2 is not so obvious. b. determine the coefficients using fminsearch c. output the coefficients as follows The initial temperature of the water is: #.41 The room temperature is: #.43 The calculated constant k is: #.###12 d. generate a plot showing the original data points as symbols and a solid line for the equation room kt T

This problem has been solved! see the answeran evil king has a cellar containing n bottles of expensive wine, and his guards have just caught a spy trying to poison the king’s wine. fortunately, the guards caught the spy after he succeeded in poisoning only one bottle. unfortunately, they don’t know which one. to make matters worse, the poison the spy used was very deadly; just one drop diluted even a billion to one will still kill someone. even so, the poison works slowly; it takes a full month for the person to die. design a scheme that allows the evil king to determine exactly which one of his wine bottles was poisoned in just one month’s time while expending at most o(logn) of his taste testers.you are not allowed to use n testers, one for each bottle, and see which one tester dies after 30 days.(no pseudocode needed. just answer in words, how many testers you use, how you use them and why you correctly identify the poisoned bottle in 30 days)
