If a polynomial function f(x) has roots -8, 1, and 6i, what must also be a root of f(x)?
Naddik [55]

Answer:

it must also have the root : - 6i

Step-by-step explanation:

If a polynomial is expressed with real coefficients (which must be the case if it is a function f(x) in the Real coordinate system), then if it has a complex root "a+bi", it must also have for root the conjugate of that complex root.

This is because in order to render a polynomial with Real coefficients, the binomial factor  (x - (a+bi)) originated using the complex root would be able to eliminate the imaginary unit, only when multiplied by the binomial factor generated by its conjugate: (x - (a-bi)). This is shown below:

(x-(a+bi))*(x-(a-bi))=\\(x-a-bi)*(x-a+bi)=\\([x-a]-bi)*([x-a]+bi)=\\(x-a)^2-(bi)^2=\\(x-a)^2-b^2(-1)=\\(x-a)^2+b^2

where the imaginary unit has disappeared, making the expression real.

So in our case, a+bi is -6i (real part a=0, and imaginary part b=-6)

Then, the conjugate of this root would be: +6i, giving us the other complex root that also may be present in the real polynomial we are dealing with.

RSB [31]

Answer:

Number of people lived in Texas =  2,242,200

Step-by-step explanation:

Given:

People per square mile = 3,737

Area of Texas = 600 square mile

Find:

Number of people lived in Texas

Computation:

Number of people lived in Texas = People per square mile x Area of Texas

Number of people lived in Texas = 3,737 x 600

Number of people lived in Texas =  2,242,200

What is the surface area of the cube with the given edge length, s?
patriot [66]
A cube has 6 sides.
 first calculate the area of 1 side  and then multiply it by 6
 

the area for one side = S^2 ( or SxS)

15^2 = 15 x 15  = 225 square inches 

now multiply that by 6:
225 x 6 = 1350 square inches total

the answer is B.
