Substitute the given values into the formula, and solve for the unknown variable.
Alla [95]

Answer:

h=\frac{1}{6}

Step-by-step explanation:

Given:

A=\frac{1}{2h} (B+b)\\

A=21, B=2, b=5 ,h= ?

We have to find the value of  'h'

So, putting the given values in the equation to find the value of 'h'.

          A=\frac{1}{2h} (B+b)

Implementing the given values in the given equations:

         

                              21=\frac{1}{2h}(2+5)\\\\ 21=\frac{1}{2h} (7)\\\\\frac{1}{2h}=\frac{21}{7}\\\\  \frac{1}{2h}=3 \\\\h=\frac{1}{6}

So, the value of 'h' is

                       h=\frac{1}{6}

Suppose matrix B is the inverse of matrix A. Use your knowledge of inverses and matrix multiplication to answer the following: A
neonofarm [45]

AB will be an Identity matrix.

<h3>What is an identity matrix?</h3>
  • A square matrix with 1s on the main diagonal and 0s everywhere else is an identity matrix.
  • The identity matrices 22 and 33, for example, are presented below.
  • These are known as identity matrices because they produce the identity matrix when multiplied by a compatible matrix.
  • If the answer to a matrix multiplication problem is an identity matrix, then each of the two matrices is an inverse matrix of the other.
  • When the matrix is multiplied by the original matrix, the result is the identity matrix.

As it is given in the description itself, if the answer to a matrix multiplication problem is an identity matrix, then each of the two matrices is an inverse matrix of the other.

Therefore, AB will be an Identity matrix.
