10. For the system of linear equation: (2x₁ + 3x₂ + x3 = -1 3x₁ + 3x₂ + x3 = 1 (2x₁ + 4x₂ + x3 = -2 a. find the coefficient matrix A and the augmented matrix [AL b. use Gauss Jordan method to find the inverse of the coefficie c. find the solution set of 'he system using Matrix inverse Me-
a. Coefficient matrix A:
A = [[2, 3, 1],
[3, 3, 1],
[2, 4, 1]]
Augmented matrix [AL]:
[A|b] = [[2, 3, 1, -1],
[3, 3, 1, 1],
[2, 4, 1, -2]]
b. The resulting matrix will be [I|A^(-1)], where A^(-1) is the inverse of the coefficient matrix A.
c. The resulting vector [x1, x2, x3] represents the solution set of the system of linear equations.
a. The coefficient matrix A and the augmented matrix [A|b] for the given system of linear equations are as follows:
Coefficient matrix A:
A = [[2, 3, 1],
[3, 3, 1],
[2, 4, 1]]
Augmented matrix [AL]:
[A|b] = [[2, 3, 1, -1],
[3, 3, 1, 1],
[2, 4, 1, -2]]
b. To find the inverse of the coefficient matrix A using the Gauss-Jordan method, we perform elementary row operations until A is transformed into an identity matrix [tex][I|A^{(-1)][/tex].
Gauss-Jordan elimination steps:
Step 1: Perform row operations to convert the first column of A to [1, 0, 0]:
R1' = R1/2
R2' = R2 - (3/2)R1
R3' = R3 - R1
Step 2: Perform row operations to convert the second column of A to [0, 1, 0]:
R2'' = R2''/3
R1'' = R1'' - (3/2)R2''
R3'' = R3'' - (3/2)R2''
Step 3: Perform row operations to convert the third column of A to [0, 0, 1]:
R3''' = R3'''/2
R1''' = R1''' - R3'''
R2''' = R2''' - R3'''
The resulting matrix will be[tex][I|A^{(-1)][/tex], where [tex]A^{(-1)[/tex] is the inverse of the coefficient matrix A.
c. Once we have the inverse matrix A^(-1), we can find the solution set of the system of linear equations by multiplying A^(-1) with the augmented matrix [A|b]:
[A|b] [tex]\times[/tex] [tex]A^{(-1)[/tex] = [x1, x2, x3]
The resulting vector [x1, x2, x3] represents the solution set of the system of linear equations.
Note: To provide the numerical values for the inverse matrix [tex]A^{(-1)[/tex] and the solution set, the calculations need to be performed manually using the given coefficients of the equations.

45,000 mL=
I really need this answer just one more Time lol
Answer:
45,000 mL (Milliliters) = 45 L (Liters)
Explanation:
The word milliliters is made up of two words, "milli" and "liter"
"Milli" means a thousand, chiefly denoting a factor of one thousandth.
That means one milliliter is one thousandth of a liter

Pls help ASAP. Pls and thx.
Answer:
(assuming the. values are the shaded areas)
area = x^2 + 2x +2
perimeter = 4x + 8
Step-by-step explanation:
you have all the side except the side of the 2 squares at the top.
The squares are 1 unit on each side because the area of the 2 slender rectangles on each side is x.
So the area is x^2 + x + x + 1 + 1
The perimeter is 1+x+1+1+1+x+1+1+1+x+1+x
(starting from the lower left side and walking around the perimeter clockwise)
(1\6-1)(3-2/5)-(1/3-1/2)
Answer:
2 1/3 (simplified)
Step-by-step explanation:
(1/6 - 1) = -5/6
(1 = 6/6)
(3 - 2/5) = 2 3/5
[3= 18 (3 * 6)]
(1/3 - 1/2) = -1/6
(you can change both of the denominators to 6 by multiplying them both by 3 / 2
So the equation now is
(-5/6)(2 3/5) - (-1/6)
-5/6 * 2 3/5 = 2 1/6 (simplified)
2 1/6 - -1/6 = 2 1/3 (simplified)

the force keeping the moon in its orbit round the earth is inversely proportional to the square of the distance from the earth.if F =6×10^5KN and R =8×10^8.find the equation connecting Fand R.
9514 1404 393
Answer:
F = 3.84×10^23/R²
Step-by-step explanation:
No units are given for distance, so we cannot give a constant of proportionality that has suitable units.
The general form for inverse square variation is ...
F = k/R²
Then the value of k can be found from ...
k = F·R² = (6×10^5)(8×10^8)^2 = 3.84×10^23
The formula relating the given F and R is ...
F = 3.84×10^23/R²

find the least common multiple of 16,30,36 no links or file
9514 1404 393
Answer:
720
Step-by-step explanation:
The LCM of these numbers will have every factor that is part of these numbers.
16 = 2^4
30 = 2 × 3 × 5
36 = 2^2 × 3^2
So, the LCM will have factors of 2^4, 3^2, and 5:
LCM(16, 30, 36) = 2^4 × 3^2 × 5 = 720
720 = 16×45 = 30×24 = 36×20
The least common multiple is 720.
