Which matrix is the product of a 3 × 3 identity matrix and the scalar 3?
Ludmilka [50]

Answer:

\left[\begin{array}{ccc}3&0&0\\0&3&0\\0&0&3\end{array}\right]

Step-by-step explanation:

In order to find out the resulting matrix, we will have to multiply the identity matric and the scalar 3:

The 3x3 identity matrix is:

\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right]

Multiplying with scalar 3:

3\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right]

The scalar will be multiplied by each element of the matrix.

Multiplying zeros with scalar 3 will give us zero. So the resulting matrix will be:

\left[\begin{array}{ccc}3*1&0&0\\0&3*1&0\\0&0&3*1\end{array}\right] = \left[\begin{array}{ccc}3&0&0\\0&3&0\\0&0&3\end{array}\right]

So the resultant matrix will be a scalar matrix with 3 at diagonal positions..

The axis of symmetry for this parabola<br><br> Y equals -5xsquared plus 10x-14
seraphim [82]

Answer:

X=1

Step-by-step explanation:

Solve for the vertex of the parabola: (v)

The axis of symmetry for a parabola will always be x=v.

Graphing the function shows the vertex at (1,-9) so the line denoting the axis of symmetry will be x=1.
