Let the matrix below act on C². Find the eigenvalues and a basis for each eigenspace in C².

forsale [732]

Hello, let's note A the matrix, we need to find $\lambda$ such that A $\lambda$ = $\lambda$ I, where I is the identity matrix, so the determinant is 0, giving us the characteristic equation as

$\left|\begin{array}{cc}1-\lambda&3\\-3&1-\lambda\end{array}\right|\\\\=(1-\lambda)^2+9\\\\=\lambda^2-2\lambda+10\\\\=0$

We just need to solve this equation using the discriminant.

$\Delta=b^2-4ac=2^2-40=-36=(6i)^2$

And then the eigenvalues are.

$\lambda_1=\dfrac{2-6i}{2}=\boxed{1-3i}\\\\\lambda_2=\boxed{1+3i}$

To find the basis, we have to solve the system of equations.

$A\lambda_1-\lambda_1 I=\left[\begin{array}{cc}3i&3\\-3&3i\end{array}\right] \\\\=3\left[\begin{array}{cc}i&1\\-1&i\end{array}\right] \\\\\text{For a vector (a,b), we need to find a and b such that.}\\\\\begin{cases}ai+b=0\\-a+bi=0\end{cases}\\\\\text{(1,-i) is a base of this space, as i-i=0 and -1-}i^2\text{=-1+1=0.}$

$A\lambda_2-\lambda_2 I=\left[\begin{array}{cc}-3i&3\\-3&-3i\end{array}\right] \\\\=3\left[\begin{array}{cc}-i&1\\-1&-i\end{array}\right]\\\\\text{For a vector (a,b), we need to find a and b such that.}\\\\\begin{cases}-ai+b=0\\-a-bi=0\end{cases}\\\\\text{(1,i) is a base of this space as -i+i=0 and -1-i*i=0.}$

Thank you

Ken paid $12 for tow magazines. The cost of each magazine was a multiple of $3. What are the possible prices of the magazines?

Finger [1]

THE MULTIPLE OF 3 ARE: 3 , 6 , 9 ,12
The 1st magazine costs either 3 or 6 or 9 , 12
The 2nd magazine costs <span>3 or 6 or 9 , 12
The value 12 is to be discarded , then are the sum of tall possibilities to get 12:

</span>mag 1st mag 2nd    total
------------ ------------ --------
3 9    12
6 6    12
9 3    12
