Consider the given matrix. 1 −1 0 5 1 4 0 1 1 Find the eigenvalues. (Enter your answers as a comma-separated list.) λ = Find the

fomenos

Answer:

Step-by-step explanation:

We have to diagonalize the matrix

$\left[\begin{array}{ccc}1&-1&0\\5&1&4\\0&1&1\end{array}\right]$

we have to solve the expression

$|A-\lambda I|=0$

Thus, by applying the determinant we obtain the polynomial

$(1-\lambda )^3+5-4=0\\(1-\lambda )^3+1=0\\$

$-\lambda^3+3\lambda^2-4\lambda+2$

$\lambda_1=1\\\lambda_2=1-i\\\lambda_3=1+i\\$

and the eigenvector will be

$v_1=(-4,0,5)\\v_2=(-1,-i,-1)\\v_3=(-1,i,1)$

Slope of -5 2). (3,9)

podryga [215]

Answer:

The slope of the given two points is $m=\frac{7}{8}$

Step-by-step explanation:

Given two points are (-5,2) and (3,9)

To find the slope with these two points

Let $(x_{1},y_{1})$ and $(x_{2},y_{2})$ be the given points

By using Slope Formula:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$m=\frac{9-2}{3-(-5)}$

$m=\frac{9-2}{3+5}$ ( subtracting and adding the corresponding terms)

$m=\frac{7}{8}$

Therefore slope is $m=\frac{7}{8}$

The slope of the given two points is $m=\frac{7}{8}$
