Given an actual demand of 64, a previous forecast of 59, and an of .3, what would the forecast for the next period be using simp
BartSMP [9]

Answer: 60.5

Step-by-step explanation:

The forecast for the next period using the simple exponential smoothing method is given by:

D\times \alpha+F(1-\alpha) , where D= actual demand for the recent period, \alpha= smoothing factor, F= forecast for the recent period .

Given: D= 64, \alpha=0.34 , F= 59

The forecast for the next period  = 64\times0.3+59(1-0.3)

\\\\= 64\times0.3+59\times0.7\\\\=19.2+41.3\\\\=60.5

Hence, the forecast for the next period = 60.5

wel

Answer:

Ok so your answer should be m = 0

Step-by-step explanation:

the explanation is to Rewrite the equation as  − 10 +7 m = − 10 .− 10 + 7 m = − 10

Move all terms not containing  m

to the right side of the equation.

7 m = 0

 Divide each term by  7

and simplify.

m = 0

Suppose a lake has a surface area of about 748 acres and an average depth of about 18 feet. About how many cubic feet are in the
zloy xaker [14]

Answer: There are 13464 cubic feet in the lake.

Step-by-step explanation:

Since we have given that

Surface area of lake = 748 acres

Average depth of lake = 18 feet

So, Volume of lake would be

Surface area of lake × Average depth

=748\times 18\\\\=13464

Hence, there are 13464 cubic feet in the lake.

Write [2(cos15*+isin15*)]^3 in standard form a+bi
Marysya12 [62]
Hello : 
by moivre theorem : 
[2(cos15*+isin15*)]^3 = 2^3(cos(3×45*)+isin(3×45*))
                                   =8 (cos45*+isin45*)
                                   = 8 ( √2/2 +i √2/2)
                                   = 4√2 + 4√2 i ..... ( <span>in standard form a+bi)
</span>a = b = 4√2
