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

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
