Find a 2 × 2 matrix b ≠ o and b ≠ i2 such that ab = ba, where a = 1 7 0 1 . b =

riadik2000 [5.3K]

If $\mathbf A$ is invertible, then we can simply choose $\mathbf B=\mathbf A^{-1}$ because for any invertible matrix $\mathbf X$ by definition we must have $\mathbf{XX}^{-1}=\mathbf X^{-1}\mathbf X=\mathbf I$ .

We have $\det\mathbf A\neq0$ , as

$\det\mathbf A=\begin{vmatrix}1&7\\0&1\end{vmatrix}=1\times1-0\times7=1$

which means $\mathbf A$ is non-singular and has an inverse. The inverse itself would be

$\mathbf A^{-1}=\dfrac1{\det\mathbf A}\begin{bmatrix}1&0\\-7&1\end{bmatrix}^\top=\begin{bmatrix}1&-7\\0&1\end{bmatrix}$

I Need The Answer Plz!!! Geometry Is Hard!!!

Scorpion4ik [409]

Answer:

B. 10

Step-by-step explanation:

First, we need to recognize that the two triangles are similar (the triangle with a leg value of 21 and the triangle with a leg value of 4 and hypotenuse x)

Let's first label the leg of the second triangle as y.

Then, we can set up this equation

$\frac{21}{y} =\frac{y}{4}$

Cross multiplying gives us

84=y^2

So, y=sqrt(84) or 2 sqrt(21).

Now, using the pythagorean theorem, we get

4^2+2sqrt(21)^2=x^2

100=x^2

x=10
