If a household appliance has a wattage of 7,043 and is in use for 9 hours, how much CO2 was produced? Round to 1 decimal.
Answers
Answer: = 62.8 pounds of CO₂
Step-by-step explanation:
1 kilowatt per hour produces 0.99 pounds of C02.
The total wattage in hours used was;
= 7,043 * 9 hours
= 63,387 watts
In kilowatts;
= 63,387/1000
= 63.387 kilowatts
CO2 produced;
= 63.387 * 0.99
= 62.75313
= 62.8 pounds of CO2

The blanks will have values 2, 3, and 1 respectively.
What is zero of a function?
Zero of a function is defined as the roots of the function for which the value of the function will be 0 at those points.
If p is the zero of the function f(x)=0 then f(p)=0.
We have,
f(x) = (x-1)² (x+3)³ (x+1)
Now,
The zero is located at x=1 and has a multiplicity of 2.
Because the number of times a given factor appears in the factored form of the equation of a polynomial is called the multiplicity.
So,
Now,
The zero is located at x = - 3 and has a multiplicity of 3.
And,
The graph of the function will touch, but not cross, the x - axis at the x - value of 1.

What is the degree of the simplest polynomial function with zeros at the square root of 3, 4i, and -2.
Answers
Answer:
Degree of polynomial → 4
Step-by-step explanation:
Conjugate roots theorem states that if a polynomial has a root (a + ib), then (a - ib) will be the other root.
In this question it has been given that a polynomial function has the zeros (roots) as x = [tex]\sqrt{3}[/tex], 4i and -2.
Therefore, the given polynomial will have four roots, [tex]\sqrt{3}[/tex], 4i, -4i and -2.
Function will be f(x) = (x - [tex]\sqrt{3}[/tex])(x + 4i)(x - 4i)(x + 2)
Degree of the polynomial → 4
