Answer:
Angle between the two vectors is 20.7718°.
Step-by-step explanation:
The given two vectors are x = (1,2,3,4) and y = (4,2,4,5)
Now the dot product between two vector is defined as
x.y = ║x║║y║cosθ
Now, x.y( dot product of x and y) = 1×4 + 2×2 + 3×4 + 4×5 = 40
║x║=
= 
║y║=
'
Thus, we get
40 =
×
×Cos θ
Thus, Cos θ = 
Cos θ = 0.935
θ = 
θ = 20.7718°
Answer:
5.0 6.0 7.0 7.5 8.0 9.0 10.0
arranging the following
5.0 , 6.0 , 7.0 , 7.5 , 8.0 , 9.0, 10.0
7.5 is the median..
It will be 12 be you divide 1/8 then 1/4 then add 8+4=12
Answer:
700mm
Step-by-step explanation:
1 metre = 100 centimetres
1 centimetre = 10 millimeters
1 metre = 100 centimetres = 1000 millimeters
0.7 metre = 70 centimetres = 700 millimeters
