Answer:
A=168 ft²
Step-by-step explanation:
18×8=144
0.5*8*6=24
24+144=168
Answer:
Step-by-step explanation:
The formula to calculate the forecast could be determine by using the exponential smoothing method :
![Ft = F(t-1) + \alpha [A(t-1) - F(t-1)]](https://tex.z-dn.net/?f=Ft%20%3D%20F%28t-1%29%20%2B%20%20%5Calpha%20%5BA%28t-1%29%20-%20F%28t-1%29%5D)
Where ,Ft is the Forecast for period t
F(t-1) is the Forecast for the period previous to t
A(t-1) is the Actual demand for the period previous to t
= Smoothing constant
To get the forecast for may and june the above formula with 
and april forecast of 500 will be used
For march
For April
For May
So forecast for May = 536.25
Answer:
The second and third line are wrong
Step-by-step explanation:
(4x³ +4x²-8x) -(8x²-16x+4)
= 4x³ +4x²-8x - 8x²+ 16x -4
= 4x³ +4x²- 8x²-8x+ 16x -4
= 4x³ -4x²+ 8x -4
In the second line:
it has to be +16x because - times - is +
it is like -1*(8x²-16x+4)
In the third line:
you can only add or subtract the xs with the same exponentation, so
4x²- 8x² and -8x+ 16x
4x²- 8x²= -4x² not +12x²
Slope = change in y / change in x
= (15 - 9) / (7 - 5)
= 6 / 2
= 3
It would be > cause it is a smaller fraction which makes the decimal a bigger number
Hope it helps
