Given polynomial is,

x - 1 + 2x³ - 3x⁴ + 5x⁵

2.1) Number of terms in the given polynomial = 5

2.2) Degree of polynomial = Highest exponent of polynomial = 5

2.3) Constant term of the given polynomial = 1

2.4) Polynomial in descending order,

5x⁵ - 3x⁴ + 2x³ + x - 1

2.5) Value of polynomial at x = -1

5(-1)⁵ - 3(-1)⁴ + 2(-1)³ + (-1) - 1 = -5 - 3 - 2 - 1 - 1

= -12

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.
