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.

PLEASE HELP! We can translate ()=2|−2|−5 to the right 3 units and up 5 units to create (). Write the equation for function g.
alisha [4.7K]

Answer:

g(x)=2\,|x-5|

Step-by-step explanation:

Recall that a horizontal translation (shift) in 3 units to the right involves directly subtracting 3 from the variable x (horizontal axis variable) , and that moving the function up 5 units involves adding to the whole function 5 units. That is:

g(x)=2\,|x-3-2|- 5+ 5\\g(x)=2\,|x-5|+0\\g(x)=2\,|x-5|
