Given A-<br> 2 2<br> 1 3<br> what is A-¹?

The inverse of matrix A = $\left[\begin{array}{cc}2&2&1&3\\\end{array}\right]$ is $A^{-1} = \frac{1}{4}$ $\left|\begin{array}{cc}3&-2&-1&2\\\end{array}\right|$

The given matrix is A = $\left[\begin{array}{cc}2&2&1&3\\\end{array}\right]$

The inverse of a matrix is given by

$A^{-1} = \frac{1}{|A|} adjA$ ...(1)

Now, determinant of matrix A is

|A| = $\left|\begin{array}{cc}2&2&1&3\\\end{array}\right|$

= (3)(2) - (2)(1)

= 6 - 2

= 4

Now, adjoint A will be

$A_{11}$ = 3

$A_{12}$ = -1

$A_{21}$ = -2

$A_{22}$ = 2

AdjA = $\left|\begin{array}{cc}3&-2&-1&2\\\end{array}\right|$

Now, substituting the values of |A| and AdjA in equation (1), we get

$A^{-1} = \frac{1}{4}$ $\left|\begin{array}{cc}3&-2&-1&2\\\end{array}\right|$

Therefore, $A^{-1} = \frac{1}{4}$ $\left|\begin{array}{cc}3&-2&-1&2\\\end{array}\right|$

Please someone help me !! :(

Answer: 27 times bigger.

Step-by-step explanation:

You need to use the following formula to find the volume of a Square pyramid:

$V=\frac{1}{3}s^2h$

Where "s" is the edge of a side of the square base and "h" is the height of the pyramid.

Knowing that:

$s_A=12\ in\\\\h_A=8\ in\\\\\\s_B=36\ in\\\\h_B=24\ in$

You can find the volume of the Pyramid A and the volume of the Pyramid B:

$V_A=\frac{1}{3}(12\ in)^2(8\ in)\\\\V_A=384\ in^3\\\\\\V_B=\frac{1}{3}(36\ in)^2(24\ in)\\\\V_B=10,368\ in^3$

Finally divide the volume of the Pyramid B and the volume of the Pyramid A, in order to find how many times bigger than the Pyramid A is the Pyramid B.

You get:

$\frac{10,368\ in^3}{384\ in^3}=27$
