Answer:
-6i
Step-by-step explanation:
Complex roots always come in pairs, and those pairs are made up of a positive and a negative version. If 6i is a root, then its negative value, -6i, is also a root.
If you want to know the reasoning, it's along these lines: to even get a complex/imaginary root, we take the square root of a negative value. When you take the square root of any value, your answer is always "plus or minus" whatever the value is. The same thing holds for complex roots. In this case, the polynomial function likely factored to f(x) = (x+8)(x-1)(x^2+36). To solve that equation, you set every factor equal to zero and solve for the x's.
x + 8 = 0
x = -8
x - 1 = 0
x = 1
x^2 + 36 = 0
x^2 = -36 ... take the square root of both sides to get x alone
x = √-36 ... square root of an imaginary number produces the usual square root and an "i"
x = ±6i
1. To the question whether it is a good idea to design a drink can from a solid nonmetal, the answer is <u>No, because nonmetals lack luster</u>.
<h3>The Luster in Nonmetal</h3>
Non-metals do not have luster because they cannot reflect light from their surface with their dull appearances. Diamond and iodine are two exceptions to lustrous non-metals.
2. The reason it is not a good idea designing a drink can from a solid nonmetal is <u>No, because nonmetals are brittle.</u> Generally, solid nonmetals are known to be <u>dull and brittle</u>. They can easily break into pieces.
Thus, non-metals are <u>not ductile or malleable</u>.

Answer:
10/3
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
The question states that Car A after two hours is at 95. We can represent this as (2, 95). We know the slope is 40, which means we can find the y intercept of Car A using point slope form: y = 40(x - 2) + 95. y = 40x + 15. This means that Car B is 5 miles east of car a, as the Y intercept of Car B is 5 greater.
Ahhhh simoooooooooooooooooon weeeeeeee
