If so, find a potential function. F = (2y,2x+z2,2yz) Select the correct choice below and fill in the answer box to complete your choice as needed. A. The function is conservative on its domain and has a potential function phi(x,y) = (2xy + C). B. The function is not conservative on its domain. A farmer with expected utility preferences with () = can experience a Bountiful or a Dry year with probabilities %80 and %20, and with $100 and $25 worth of crops, respectively.(a) Calculate the expected value and expected utility of the "lottery" the farmer is facing. What is the certainty equivalent and risk premium of this lottery for the farmer?(b) The farmers risk-neutral friend offers him the following "insurance" scheme:"Give me $B if the year is bountiful and I will compensate you with $D if the year is dry"What should the numbers B and D be so that the friend would be willing to offer such a scheme and the farmer would want to accept it? (Just write down the conditions, that is, the mathematical inequalities that B and D should satisfy; dont try to solve these equations !)(c) For which set of (B,D) values: (i) (19,96) or (ii) (36,56) or (iii) (19,75) the friend would offer and the farmer would accept the scheme?

A 550 N physics student stands on a bathroom scale in an 850 kg (including the student) elevator that is supported by a cable. As the elevator starts moving, the scale reads 450 N. Find the acceleration (magnitude and direction) of the elevator, What is the acceleration is the scale reads 670 N? (c) If the scale reads zero, should the student worry?
