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
The dot product of the two vectors will be given as follows:
v*w=(-7i+4j)*(-6i+5j)
=(-7*(-6))i+(4*5)j
=-42i+20j
Hence the answer is:
v*w=(-42i+20j)
Answer:
Angle 1 is = 54° ( vertically opposite angles)
Angle 2 is = Angle 1 (corresponding angles are equal)
therefore Angle 2 = 54°
B) Rotterdam. Because sea level is 0 and Rotterdam is the only one below sea level
