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.

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-​

Answers

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.

(1\6-1)(3-2/5)-(1/3-1/2)

Answers

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.​

Answers

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

The squares are 1 unit on each side because the area of the 2 slender rectangles on each side is x.

There are three tellers, and the bank opens when all three are ready. No customers can enter the bank before it is open. Throughout the day, customers will visit the bank to either make a withdraw or make a deposit. If there is a free teller, a customer entering the bank can go to that teller to be served. Otherwise, the customer must wait in line to be called. The customer will tell the teller what transition to make. The teller must then go into the safe, for which only two tellers are allowed in side at any one time. Additionally, if the customer wants to make a withdraw the teller must get permission from the bank manager. Only one teller at a time can interact with the manager. Once the transaction is complete the customer leaves the bank, and the teller calls the next in line. Once all 100 customers have been served, and have left the bank, the bank closes.
