Answer:

\begin{bmatrix}-2\\0 \end{bmatrix}

Step-by-step explanation:

We have the product, 2\times \begin{bmatrix}-1\\0 \end{bmatrix}.

It is known that,

'When we multiply a scalar with a matrix, the scalar is multiplied by each element of the matrix'.

So, we get,

2\times \begin{bmatrix}-1\\0 \end{bmatrix}.

⇒ \begin{bmatrix}-1\times 2\\0\times 2 \end{bmatrix}

⇒ \begin{bmatrix}-2\\0 \end{bmatrix}

So, the resulting product is \begin{bmatrix}-2\\0 \end{bmatrix}.

Answer:

\left[\begin{array}{ccc}-2\\0\\\end{array}\right]

Step-by-step explanation:

We have to find the product of a scalar and 2×2 matrix.

By finding the product of a scalar and a matrix ,we have to multiply the scalar by each entry of the matrix.

2.\left[\begin{array}{ccc}1\\4&\end{array}\right]

\left[\begin{array}{ccc}2.(-1)\\2.0\\\end{array}\right]

\left[\begin{array}{ccc}-2\\0\\\end{array}\right] which is the product of a scalar and a matrix.

Use a benchmark fraction to compare 7 10 ths and 5 12 ths. Explain how you found the answer
elixir [45]
<span>Benchmark fractions are created when we make two different fractions have the same numerator or denominator. In thisi case, we will produce the same denominator. The LCM of 10 and 12 is 60. So the fractions become 42/60 and 25/60. Since the fraction with the larger numerator has a larger value when the denominators are the same, 7/10 is larger than 5/12.</span>
