QUESTION 10 Take the derivative of: U(c1,c2) = 0.5*In(c1) + 0.9*In(c2). Then evaluate the partial derivative w.r.t. c1 at c1=5, c2=2. Note: Enter your answer as a decimal with at least 2 digits after the decimal point. QUESTION 11 Take the derivative of: U(c1,c2) = 0.5*In(c1) + 6*In(c2). Then evaluate the partial derivative w.r.t. c2 at c1=5, c2=2. Note: Enter your answer as a decimal with at least 2 digits after the decimal point
