If the forecasted demand for the week of August 31 is 345 and alpha ​= 0.20​, using exponential​ smoothing, develop the forecast for each of the weeks with the known demand and the forecast for the week of October 12 ​(round your responses to two decimal​ places).

the answer to the expression is 83

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

b. b < 1 might be the correct answer
