Answer:

<h2>D and A are equal</h2>

Step-by-step explanation:

Two matrices A and B are said to be equal if both matrices have the same number of rows and columns. Given the following matrices

A = -2\left[\begin{array}{ccc}-6&4\\3&7\\12&10\end{array}\right] \\multiplying\ the \ matrix\ through\ by\ -2\ will\ give\\A = \left[\begin{array}{ccc}12&-8\\-6&-14\\-24&-20\end{array}\right] \\\\\\B =3 \left[\begin{array}{ccc}-2&2&8\\8&5&6\end{array}\right] \\B = \left[\begin{array}{ccc}-6&6&24\\24&15&18\end{array}\right] \\\\\\D = \left[\begin{array}{ccc}12&-8\\-6&-14\\-24&-20\end{array}\right]

From the above matrices, it can be seen that matrix A and C both has 3 rows and 2 columns each which matrix b has 2 rows and 3 columns.

Based on the conclusion, it can be seen that matrices A and D are equal since they have the same number of rows and columns

What is the value of R
frutty [35]

Answer:

2.45 × 10^{6}

Step-by-step explanation:

using the rules of exponents

• \frac{a^{m} }{a^{n} } = a^{(m-n)}

• (a^m)^{n} = a^{mn}

evaluating the numerator

(3.8 × 10^{5})² = 3.8² × (10^5)^{2} = 14.44 × 10^{10}

R = \frac{14.44.10^{10} }{5.9.10^{4} }

  = \frac{14.44}{5.9} × \frac{10^{10} }{10^{4} }

  = 2.45 × 10^{6} ← to 2 dec. places

According to the Rational Root Theorem, which function has the same set of potential rational roots as the function g(x) = 3x5 –
nadya68 [22]

Option A, The option that has the same potential roots according to the rational root theorem is 3x5 – 2x4 – 9x3 + x2 – 12.

<h3>How to solve for the roots</h3>

We have p, this is the factors of the number 12.

The factors are ±(1, 2, 3, 4, 6, 12)

We have factors of q = 3

= ±(1, 3)

The rational roots are the roots that have the same factors that are contained in the question.

Hence the answer is A.
