For the exponential decay function =y300(0.9)x What is the initial amount of the quantity modeled by this function What is the decay rate for the function (also known as the relative change)? Write as a percentage. .
A check-processing center uses exponential smoothing to forecast the number of incoming checks each month. The number of checks received in June was 40 million, while the forecast was 42 million. A smoothing constant of 0.15 is used. a) Using exponential smoothing and given a, the forecast for the month of July = million checks received (round your response to one decimal place). b) If the check-processing center received 46 million checks in the month of July, then using exponential smoothing and given a, the forecast for the month of August = million checks received (round your response to one decimal place). c) Exponential smoothing may not be an appropriate method to use for the check-processing center because: A. the check-processing center should observe an increasing trend in its processing requirements. B. the check-processing center should observe a cyclical trend in its processing requirements. C. the check-processing center's forecast is very hard to make as its processing…
