Why are (1,2) and(2,1) not equal ordered pair?
Answers
Answer:
The pairs ( 1 , 2 ) and ( 2 , 1 ) are not equal because their respective elements are not equal.
Step-by-step explanation:
The pair of elements which are in specific order is called an ordered pair. The pair ( 1 , 2 ) is not same as the pair ( 2 , 1 ). In the pair ( 1 , 2 ) 1 is in the first position and 2 is in the second position. In the pair ( 2 , 1 ), 2 is in the first position and 1 is in the second position.
Two ordered pairs ( a , b ) and (c , d ) are said to be equal if a = c and b = d. We write ( a , b ) = ( c , d ).

Use the i formation major of 1..... look at picture
Answers
Explanation:
You basically plug in x = 20, which is the same as saying "replace x with 20". Then you perform arithmetic to simplify each expression. Both simplify to 90, so angle 1 and angle 2 are the same measure. These angles are alternate interior angles, so we'll use the converse alternate interior angle theorem to conclude the lines are parallel.
Note: the alternate interior angle theorem says that if we have parallel lines, then the alternate interior angles are congruent. So the converse goes in reverse of this.

the key features for this situation.
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given the expression :
Chiang is filling a 50 ft3 container with water at a rate of 0.5 ft3/min. Interpret
50 ft^3 represents the volume of the container which is a product of its length, width and height. The rate is said to be 0.5ft^3 /min. The stated rate represents the volume of the container which Chiang fills each minute. The rate could be obtained by taking the proportion of the entire volume of the container and the time it takes Chiang to fill it.
Here, it will be :
Rate = ( volume of container (ft^3) / time taken (minutes))
Hence 0.5ft^3/min means on average Chiang's fills a volume of 0.5ft^3 of the container each minute.
Suppose you invested $1500 in the stock market 2 years ago. During the first year, the value of the stock increased by 16%. During the second year, the value of the stock decreased by 16%. How much money is your investment worth at the end of the two-year period? (Note: The answer to this question is not $1500.)
Answers
Answer:
$1,461.60
Step-by-step explanation:
Value of the stock in the first year if value increased by 16% = 1500 x (1.16) = $1740
1.16 = 100% + 16% = 116%
Value of the stock in the second year if value decreased by 16% = $1740 x 0.84 = $1,461.60
0.84 = 100% - 16% = 84%

Answer:
a. Yes
b. Yes
c. Yes

Step-by-step explanation:
a. Yes, n(x) is a polynomial of one single term (also called monomial) because it contains variables raised to positive integers.
b. Yes, m(x) is a polynomial of also one single term (also called monomial) because it contains variables raised to positive integers.
c. The quotient of n(x) / m(x) can be reduced to a polynomial of one single term as follows:
[tex]\frac{n(x)}{m(x)} =\frac{6\,x^5\,y^7}{2\,x^3\,y} =3\,x^2\,y^6[/tex]
which as can be seen, also contains variables raised to positive integers.
d. The degree of the polynomial resultant is the addition of the powers of all variables present (x and y) which results in: 2 + 6 = 8
Therefore the degree of this polynomial is 8.

Which numbers produce an irrational number when added to 5/8
Answers
Answer:
Irrational numbers
Step-by-step explanation:
Any irrational number plus a rational number like (5/8) creates another irrational number.
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
An irrational number is a number that cannot turn into a fraction.
If you add an irrational number to a rational number, the sum is an irrational number because since the number cannot be ended and/or written into a fraction.
Irrational numbers are: Pi and infinity. Pi doesn't ever end, and all the digits (after 0) are different (it's a formula). Infinity has no end, so you cannot write infinity as a fraction.
Pi plus 5/8 is an irrational number.
Infinity plus 5/8 is also an irrational number.

[tex] \because x : (x + 5000) = 4 :5[/tex]
[tex] \therefore \frac{x}{(x + 5000)} = \frac {4}{5}[/tex]

The vertices A, B, C of a triangle are (2,1),(5,2),and (3,4) respectively . Find the coordinate of the circumcentre and also the radius of the circum-circle of the triangle
Answers
Answer:
Circumcenter = (4,0)
Circumcircle = √5
Step-by-step explanation:
The circumcentre is the point of intersection of the perpendicular bisectors of a triangle. The vertices of the triangle are equidistant to the circumcentre.
Let us assume the coordinate of the circumcentre is at O(x, y). Therefore the distance between the cirmcumcenter and the vertices are:
[tex]AO=\sqrt{(x-2)^2+(y-1)^2} =\sqrt{x^2-4x+4+(y^2-2y+1)}\\=\sqrt{x^2+y^2-4x-2y+5} \\\\BO=\sqrt{(x-5)^2+(y-2)^2} =\sqrt{x^2-10x+25+(y^2-4y+4)}\\=\sqrt{x^2+y^2-10x-4y+29} \\\\CO=\sqrt{(x-3)^2+(y-4)^2} \\=\sqrt{x^2-9x+9+(y^2-8y+16)}=\sqrt{x^2+y^2-9x-8y+25} \\[/tex]
AO = BO, therefore
√(x² + y²-4x-2y+5) = √(x² + y² - 10x - 4y + 29)
x² + y²-4x-2y+5 = x² + y² - 10x - 4y + 29
6x + 2y = 24 (1)
BO = CO
√(x² + y² - 10x - 4y + 29) = √(x² + y² - 9x - 8y + 25)
x² + y² - 10x - 4y + 29 = x² + y² - 9x - 8y + 25
-x + 4y = -4 (2)
Multiply equation 2 by 6 and add to equation 1:
26y = 0
y=0
Put y = 0 in -x + 4y = -4
-x + 4(0) = -4
x = 4
The cicumcenter is at (4, 0)
The radius of the circumcircle = AO = BO = CO. Therefore:
[tex]Radius=AO=\sqrt{(4-2)^2+(0-1)^2} =\sqrt{4+1}=\sqrt{5}[/tex]

Members of a community center have decided to paint a large circular mural in the middle of the parking lot. The radius of the mural is to be 11 yards. Before they begin painting the mural, they use a rope to form the outline. How many yards of rope will they need?
Answers
Answer:
69.124 yards of ropeStep-by-step explanation:
This problem bothers on the mensuration of flat shapes, circles.
given that the members of the community used rope as outline for the circular shape mural.
we can tell that the perimeter of the mural is same as the perimeter of the rope.
Hence the length of rope used is same as the perimeter of the circular mural.
we know that the perimeter of a circle is given as
[tex]C=2\pi r\\\\[/tex]
substituting radius r= 11 yards
we have

Mr Ondonez gives his students 34 quizzes over 17 weeks. They are given the same number of quiz per week. To calculate the number of quiz given per week, we have to divide the total number of quiz given by the total number of weeks. Therefore:
Number of quiz per week = Total number of quiz / Total number of weeks

Both the Galapagos Islands and the island of Naura are on the equator, but the Galapagos Islands are at 90.30°W whereas the island of Naura is at 166.56°E. How far is it from the Galapagos Islands to Naura traveling over the Pacific ocean along the equator, correct to the nearest km?
Answers
Answer:
11521 km
Step-by-step explanation:
The computation is given below:
But prior to reaching the final solution first the following calculations need to be computed
Angle between the Galapagos and Nauru is
= 90.30° + 166.56°
= 256.86°
As we know that the total of angles is 360 degrees
Now the major arc and the minor arc is
= 360° - 256.86°
= 103.14°
So, the angles between galapagos islands is
= 180° - 90.30°
= 89.70°
And, angles between the naura island is
= 180° - 166.56°
= 13.44°
Now the sum of this two island is
= 89.70° + 13.44°
= 103.14°
Therefore The length is
[tex]= \frac{\pi r}{180^{\circ}} \times \theta \\\\ = \frac{6,400 \pi}{180^{\circ}} \times 103.14^{\circ}[/tex]
= 11521 km
1. Which range of numbers is most appropriate for the y-axis scale and interval on a graph given the
Range: 10 - 35; Interval 10
Range: 0-35; Interval: 5
Range: 0 - 30; Interval 5
Range: 10 - 30; Interval: 5
Answers
Answer:
Option B.
Step-by-step explanation:
We need to find the range of numbers is most appropriate for the y-axis scale and interval on a graph for given table.
From the given table it is clear that the minimum value of y is 10 and the maximum value of y is 34.
It means 10 and 34 must be included in the Range.
In option C and D 34 in not included in the range, so these options are incorrect.
In option A, 10 is the minimum value of range and interval of 10 is not possible for the range 10-35, because it contains only multiple of 10 on the y-axis. So, this option is incorrect.
In option B, both 10 and 34 are included and interval of 5 is possible for range 0-35.
Therefore, the correct option is B.
