Step-by-step explanation:

This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts.

Horse = x = 1 head and 4 feet

Chicken =y = 1 head and 2 feet

Horse + chicken = x + y = 43 ( total heads)

Horse = 43 - y

4x + 2y = 122

4(43-y) + 2y = 122

Simplify:

172-4y + 2y = 122

Combine like terms

172-2y = 122

Subtract 172 from both sides

-2y = -50

Divide both sides by-2

Y = 25

X + y = 43

X + 25 = 43

X = 18

There are 18 horses and 25 chickens.

The area of glass used to make the window is 3200 sq. cm.

A kite is a member of quadrilateral which has two diagonals. The area of a kite can be determined by;

area of a kite = (length of diagonal 1 * length of diagonal 2) / 2

Therefore to determine the square meter of glass used to make the window in the given question, we have;

length of diagonal 1 = 40 + 40

                                 = 80 cm

length of diagonal 2 = 35 + 45

                                  = 80 cm

area of the window = (80*80)/2

                                 = 6400/2

area of the window = 3200 sq. cm.

Therefore, 3200 sq. m. of glass was used to make the window.

An equation that could be used to determine M, the unknown side length of the logo is X = (36/5) x M

Let's assume that the unknown side length of the logo is 'M'. The logo is a rectangle, and the area of a rectangle is given by multiplying its length and width. Since we know the length of the logo is 7(1)/(5) feet, we can write the equation:

A = L x W

where A is the area of the logo, L is the length of the logo, and W is the width of the logo.

Substituting the given values, we get:

A = (7(1)/(5)) x M

or

A = (36/5) x M

Now, we know that the area of the logo is exactly the maximum area allowed by the building owner. Let's assume this maximum area is 'X'. So, we can write another equation:

A = X

Combining both equations, we get:

X = (36/5) x M

This is the required equation that could be used to determine the unknown side length 'M' of the logo if we know the maximum area allowed by the building owner 'X'.

The lengths of the two legs of the right triangle are 58 and 839, in increasing order.

We have,

The formula given is incorrect.

The correct formula for Pythagorean triples with a given integer z is:

(z² - 1², 2z, z² + 1²)

Using this formula, we can find the two legs of the right triangle with hypotenuse 29 as follows:

z² + 1² = 29²

z² + 1 = 29²

z² = 29² - 1

z² = 840

z = √840

z = 28.98

Since z must be an integer, we can try integer values close to 28.98 to find one that works.

Trying z = 29,

a = z² - 1² = 840 - 1 = 839

b = 2z = 58

c = z² + 1² = 840 + 1 = 841

Therefore,

The lengths of the two legs of the right triangle are 58 and 839, in increasing order.

a) The elimination matrices used were E1, E2, and E3.

b) Three times the first row from the third row, using the elimination.

(a) To put matrix A into upper triangular form, we can use elimination matrices to eliminate the entries below the diagonal.

First, we can add the first row to the second and third rows, using the elimination matrix

E1 = |1 0 0|

       |1 1 0|

       |1 0 1|

E1A = | -1 -1 -1 1

          0 -2 0 0

          0 0 -2 0

          1 -1 -1 0

          1 -1 -1 -1

          1 -1 -1 -1

          1 -1 -1 -1

          1 -1 -1 -1|

Next, we can add the second row to the third row, using the elimination matrix

E2 = |1 0 0|

       |0 1 0|

       |0 1 1|

E2(E1A) = | -1 -1 -1 1

               0 -2 0 0

               0 0 -2 0

                1 -1 -1 0

             0 -2 -2 -1

               1 -1 -1 -1

               1 -1 -1 -1

               1 -1 -1 -1|

Finally, we can add the fourth row to the fifth, sixth, seventh, and eighth rows, using the elimination matrix

E3 = |1 0 0 0 0 0 0 0|

       |0 1 0 0 0 0 0 0|

       |0 0 1 0 0 0 0 0|

       |0 1 0 1 0 0 0 0|

       |0 0 0 0 1 0 0 0|

       |0 0 0 0 0 1 0 0|

       |0 0 0 0 0 0 1 0|

       |0 0 0 0 0 0 0 1|

E3(E2E1A) = | -1 -1 -1 1

                    0 -2 0 0

                    0 0 -2 0

                     1 0 -2 1

                  0 -2 -2 -1

                 0 -2 -2 -2

                 0 -2 -2 -2

                 0 -2 -2 -2|

Therefore, the upper triangular form of A is:

| -1 -1 -1 1

0 -2 0 0

0 0 -2 0

0 0 0 -2

0 0 0 0

0 0 0 0

0 0 0 0

0 0 0 0|

The elimination matrices used were E1, E2, and E3.

(b) To put matrix B into upper triangular form, we can use elimination matrices to eliminate the entries below the diagonal.

First, we can subtract twice the first row from the second row, using the elimination matrix

E1 = |1 0 0|

      |-2 1 0|

      |0 0 1|

E1B = | 1 0 1

Answer:

B (1, -3)

Step-by-step explanation:

Step 1:  Use the midpoint formula to find the coordinates of the endpoint:

Normally, we find the midpoint of a segment using the midpoint formula, which is given by:

M = (x1 + x2) / 2, (y1 + y2) / 2, where

Since we're solving for the coordinates of an endpoint, we can allow (-5, 7) to be our (x1, y1) point and plug in (-2, 2) for M to find (x2, y2), the coordinates of the endpoint B:

x-coordinate of B:

x-coordinate of midpoint = (x1 + x2) / 2

(-2 = (-5 + x2) / 2) * 2

(-4 = -5 + x2) + 5

1 = x2

Thus, the x-coordinate of the endpoint B is 1.

y-coordinate of B:

y-coordinate of midpoint = (y1 + y2) / 2

(2 = (7 + x2) / 2) * 2

(4 = 7 + x2) -7

-3 = y2

Thus, the y-coordinate of the endpoint B is -3.

Thus, the coordinates of the endpoint B are (1, -3).

What is Logical Error/Fallacies?

Common thinking flaws called fallacies will impeach the logic of your argument. Fallacies can be irrelevant or invalid arguments, and they are frequently recognised since they don't have any supporting data.

Basic Logic - knowing the study of current reasoning is basic logic.

Logic pertains to all subjects, since people can reason about anything they can think about politics, the art , Literature, business, the sciences and every day problems are all subject open to reasoning.

Few times ago , I was in a political party rally. I observed that one think clever politician knows very well how to manipulate public opinion , contestant addressing and promising about that is not in even going to possible but many of them endorse strong convictions , that whatever he told is going to be true , people don't even think for reason with the  promises that he did.
