Question
Wheat production in a given year, W, depends on the average temperature T and the annual rainfall R. Scientists estimate that the average temperature is increasing at a rate of 0.25oC/year, and rainfall is decreasing at a rate of 0.6 cm/year. They also estimate that at currrent production levels, ?W?T=?5 and ?W?R = 4. Estimate the current rate of change of wheat production dWdt

Scientific estimate that the average temperature at a rate of 0.25 Degree C/ year, and rainfall is decreasing at a rate of 0.6 cm/year. They also estimate that at current production levels, W/ T = -5 and W/ R = 4. Estimate the current rate of change of wheat production dw/dt. dw/dt =
Explanation / Answer
it will be {(-5)*0.25+4(0.6)}=1.15
