Consider a refrigerator that consumes 320 W of elec- tric power when it is running. If the refrigerator runs only one quarter of
irinina [24]

Answer: The refrigerator cost in this month is $4.5 approximately.

Step-by-step explanation:

Since we have given that

Amount of watt of electric power = 320 W

Number of days = 30

Unit cost of electricity = $0.13/Kwh

Hold factor = \dfrac{1}{4}

Number of hours in a month = 24

So, the refrigerator cost in this month would be

0.13\times 0.32\times \dfrac{1}{4}\times 30\times 24\\\\=\$7.488

Hence, the refrigerator cost in this month is $4.5 approximately.

The resulting matrix of the row operation is given as follows:

R = \left[\begin{array}{ccc}7&4.5&-6\\-6&-3&12\end{array}\right]

<h3>How to find the resulting matrix?</h3>

We apply the row operation on the original matrix, given as follows:

A = \left[\begin{array}{ccc}4&3&0\\-6&-3&12\end{array}\right]

The operation is given by:

R_1 = R_1 - 0.5R_2

That is, applying to each element, we have that:

  • 4 - 0.5(-6) = 7.
  • 3 - 0.5(-3) = 4.5.
  • 0 - 0.5(12) = -6.

Hence the resulting matrix is:

R = \left[\begin{array}{ccc}7&4.5&-6\\-6&-3&12\end{array}\right]
