2 answers:

4 0

56/97 is already in its simplest form.
24/42 can be reduced to 4/7 by dividing the original fraction by 6/6

I hope this helps :)

Expression of "Eight less than half the sum of 4 and k” into symbol

jolli1 [7]

Answer:

$\frac{4+k}{2} -8$

Step-by-step explanation:

We're going to have to work backwards.

The sum of 4 and k is $4+k$ .

Half is simply that divided by 2.

$\frac{4+k}{2}$

Now, we'll subtract 8 from it.

$\frac{4+k}{2} -8$

Bam!

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!!
