For any polynomial with a complex root, the imaginary part of the complex root always has positive and negaive component. Since one of the roots of this polynomial is 6i, then -6i must also be a root of the function.

Aaron used links to create a chain 28.9 cm long.Each link is 1.7 cm long.How many links are in the chain?
dusya [7]
You are given the length of the chain equal to 28.9cm. For each link, the length is 1.7cm long. You are required to find how many links are there in the chain. You just divide 28.9 cm by 1.7 cm to get the answer. The solution is,  
<span>
Number of links = chain length/link  length</span>
Number of links = (28.9cm)/(1.7cm)
<span>Number of links = chain length/link  length</span>
Number of links = 17  
<span><u><span>There are 17 links in a 28.9cm chain length.</span></u><u /></span>

If AB = BC = CA, what is m1?
Alborosie

Answer:

60°

Step-by-step explanation:

All the side lengths of the triangle have the same measurement. This makes it an equilateral triangle. By the definition of an equilateral triangle, all the angles are congruent, therefore all their measurements are the same. There are 3 total angles in a triangle, and the total sum of the angel measurements of a triangle is 180. Divide 180 with 3:

180/3 = 60

60° is your answer.

Write the ratio in the lowest terms. 20 ft to 12 ft
jenyasd209 [6]

Answer:

5 ft : 3 ft

Step-by-step explanation:

Ratios are always fractions so we can turn this to a fraction; \frac{20}{12}

Then to reduce to it's lowest terms divide by a number that can divide both of them. Lets divide by 2 since it can divide the two numbers

\frac{10}{6}

We can still divide by 2 since it can divide both numbers = \frac{5}{3}

Since no number can divide both of them at the same time the answer is \frac{5}{3} OR 5 ft : 3 ft
