Answer:
The answer to this question can be defined as follows:
a)
cosine: 0.707
correlation: 0
Euclidean: 3.16
b)
cosine: 1
correlation: 1
Euclidean: 0
Jaccard: 1
c)

d)
cosine: -0.333
correlation: -0.3333
Jaccard: 0.5
e)
cosine: -0.7075
correlation: 0.2132
Step-by-step explanation:
a) cosine:
[tex]x \times y( 0 \times 2+ 0 \times 2 +1 \times 2+1 \times 2) = 4\\\\ x= \sqrt{2} = 1.414\\\\y= \sqrt(16)=4\\\\\cos (x\times y) = \frac{x\times y}{x\times y}\\\\\cos (x\times y) = \frac{4}{1.414\times 4}\\\\= 0.707[/tex]
correlation:
[tex]\ corr(x,y) =[\frac{covariance (x,y)}{standec(x) \times standdev(y)}]\\X \ mean = 0.5\\Y \ mean = 2\\covariance (x,y) = 0\\standdev(x) = 0.5774\\standdev(y) = 0\\corr(x,y) = 0[/tex]
Euclidean:
[tex]d(x,y) = \sqrt((0-2)^2+(0-2)^2+(1-2)^2+(1-2)^2)\\d(x,y) = 4+4+1+1\\d(x,y)= \sqrt(10)\\d(x,y)= 3.16\\[/tex]
by applying above formula we get all the values.

What is the value of h?
40°
h = 20
h = 35
n = 55
h = 70
Answer:
55
Step-by-step explanation:
All triangles have a sum of 180°
180 - 40 = 140
Since the triangle is an isosceles triangle, then you are going to divide 140 by 2 because the base angles of an isosceles triangle are congruent.
140 / 2 = 70
Now that we know that the measurement of the two base angles is 70, we can find h.
2h represents the exterior angles. Exterior angles are always supplementary to the interior angles. So, we can simply subtract 70 from 180.
180 - 70 = 110
Now, we can divide 110 by 2 to find h.
110 / 2 = 55
So, h equals 55. So, the answer is the third option.

What is the perimeter of rectangle JKLM with vertices J(-1,3),K(2,3),L(2,-5), and M(-1,-5)
Answer:
And we can find the distance between JK like this:
[tex] d_{JK} =\sqrt{(3-3)^2 +(2+1)^2}= 3[/tex]
And we can do something similar for KL and we got:
[tex] d_{KL} =\sqrt{(-5-3)^2 +(2-2)^2}= 8[/tex]
And we can do something similar for LM and we got:
[tex] d_{LM} =\sqrt{(-5+5)^2 +(-1-2)^2}= 3[/tex]
And we can do something similar for MJ and we got:
[tex] d_{MJ} =\sqrt{(-5-3)^2 +(-1+1)^2}= 8[/tex]
And the perimeter would be:
[tex] P = d_{JK} + d_{KL} +d_{LM} +d_{MJ} = 3+8+3+8 =22[/tex]
Step-by-step explanation:
For this case we can use the formula for the euclidean distance given by:
[tex] d = \sqrt{(y_2 -y_1)^2 +(x_2 -x_1)^2}[/tex]
And we can find the distance between JK like this:
[tex] d_{JK} =\sqrt{(3-3)^2 +(2+1)^2}= 3[/tex]
And we can do something similar for KL and we got:
[tex] d_{KL} =\sqrt{(-5-3)^2 +(2-2)^2}= 8[/tex]
And we can do something similar for LM and we got:
[tex] d_{LM} =\sqrt{(-5+5)^2 +(-1-2)^2}= 3[/tex]
And we can do something similar for MJ and we got:
[tex] d_{MJ} =\sqrt{(-5-3)^2 +(-1+1)^2}= 8[/tex]
And the perimeter would be:
[tex] P = d_{JK} + d_{KL} +d_{LM} +d_{MJ} = 3+8+3+8 =22[/tex]
The perimeter of the rectangle with the given vertices is: 22 units.
Recall:
Perimeter of a rectangle = 2(length x width)Distance between two vertices is calculated using: [tex]d = \sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}[/tex]Thus, find the length (JK) and width (KL) of the rectangle.
Width of rectangle = distance between J(-1,3) and K(2,3):
Substitute[tex]JK = \sqrt{(3 - 3)^2 + (2 - (-1))^2} \\\\JK = \sqrt{(0)^2 + (3)^2} \\\\JK = \sqrt{9} \\\\JK = 3[/tex]
Length of rectangle = distance between K(2,3) and L(2,-5)
Substitute[tex]KL = \sqrt{(-5 - 3)^2 + (2 - 2)^2} \\\\KL = \sqrt{(-8)^2 + (0)^2} \\\\KL = \sqrt{64} \\\\KL = 8[/tex]
Perimeter of the rectangle = 2(length x width)
SubstitutePerimeter of the rectangle = 2(8 + 3)
Perimeter = 2(11)

What' the mean 3,2,2,12 6,5,14,4
Answer: 6
Explanation: The mean of a data set is the sum of the numbers in the data set divided by however many numbers are in the data set.
So, let's begin by adding the numbers.
So we have 3 + 2 + 2 + 12 + 6 + 5 + 14 + 4 which is 48.
Now we divide 48 by the number of numbers in the set which is 8.
48 ÷ 8 is 6.
So the mean of the given data set is 6.

Suppose A is an m × n matrix in which m> n. Suppose also that the rank of A equals n Show that A is one to one. Hint: If not, there exists a vector x such that Ax = 0, and this implies at least one column of A is a linear combination of the others. Show this would require the rank to be less than n.
Step-by-step explanation:
If T:Rn→Rm is a linear transformation and if A is the standard matrix of T, then the following are equivalent:
1. T is one-to-one.
2. T(x) = 0 has only the trivial solution x=0.
3. If A is the standard matrix of T, then the columns of A are linearly independent.
Here, A is a mxn matrix where m ≥ n and the rank of A equals n. It implies that the columns of A are linearly independent, for, otherwise, the rank of A would be less than n. Hence the linear transformation represented by A is one-to-one.

24 cm
0 27 cm
Answer:
A on e2020
Step-by-step explanation:
The solution is, The length of line segment AB is 3.4cm.
What is Line segment?Line segment is the part of line which have two endpoint and bounded by two distinct end points and it contain every point on the line which is between its endpoint.
here, we have,
The area of octagon is given as 2a^2(1+sqrt{2})
Where a is the side of octagaon.
All sides of octagon are same.
now, we get,
As, 2a^2(1+sqrt{2}) = 54cm
so, we have,
Then, a^2 = 54/2(1+sqrt{2})
a^2 = 54/4.828
a^2 = 11.19
a = 3.4 cm
Hence, The solution is, The length of line segment AB is 3.4cm.

Answer:
4) c = 38
5) x = 50
Step-by-step explanation:
4) The marked angles are a "linear pair", meaning their total is 180°:
3c° +(2c -10)° = 180°
5c = 190 . . . . . . . divide by °, add 10, collect terms
c = 38 . . . . . . . . . divide by 5
__
5) The interior angle at C brings the total of the marked angle and the interior angle to 360°
330° + (interior angle) = 360°
(interior angle) = 30° . . . . . . . . . subtract 330°
The interior angles of the triangle total 180°, so we have ...
x° +2x° +30° = 180°
3x = 150 . . . . . . . . . . . . . divide by °, subtract 30
x = 50 . . . . . . . . . divide by 3
