How do I solve this, pretty urgent please.

Andreas93 [3]

Answer:

1

Step-by-step explanation:

<u>Substitute:</u>

$x^{0.5} = y$

<u>Then the expression becomes:</u>

$(\dfrac{1+y^3}{1-y+y^2}-y) \dfrac{1-y^2}{1-y} -y=\\$
$(\dfrac{(1+y)(1-y+y^2)}{1-y+y^2}-y) \dfrac{(1-y)(1+y)}{1-y} -y=$
$(1+y-y)(1+y)-y=$
$1(1+y)-y=$
$1+y-y=$
1

The result is 1 regardless the value of x other than 1.

Given an actual demand of 59, a previous forecast of 64, and an alpha of .3, what would the forecast for the next period be usin

marshall27 [118]

Answer:

62.5

Step-by-step explanation:

Data provided in the question:

Actual demand = 59

Previous forecast = 64

Alpha = 0.3

Now,

The forecast for the next period be using simple exponential smoothing will be given as

= [ Alpha × Actual demand ] + [ (1 - Alpha) × Previous forecast ]

= 0.3 × 59 + [ ( 1 - 0.3 ) × 64 ]

= 17.7 + 44.8

= 62.5

We know that In right angle triangle c^2 = a^2 + b^2.
19^2 = 3^2 + b^2
b = (361 - 9)^1/2 = 18.761663039294
Now for angles
sin(A) = a/c = 3/19
A = sin{-1}(3/19) = 9.0847202873911
A = 9.0847202873911
sin(B) = b/c = 18.761663039294 / 19
B = sin{-1}(18.761663039294 / 19) = 80.915279712614
B = 80.915279712614
