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)

HOPE THIS HELPS!!

Find the total lateral area of the following
maxonik [38]

Answer:

15π cm²

Step-by-step explanation:

The total lateral area of a cone

= πr√h² + r²

= √h² + r² = l

h = Height = 4cm

r = radius = 3cm

Hence:

= π × 3 √4² + 3²

= 3π × √16 + 9

= 3π × √25

= 3π × 5

= 15π cm²
