Mandarinka [93]3 years ago

Answer:

x²-(i-3)x- 3i

Step-by-step explanation:

What is a third-degree polynomial function P(x) with rational coefficients so that P(x) = 0 has roots −3 and i?

Given the toots of the polynomial to be -3 and i, the factors of the polynomial will be (x+3) and (x-i)

Taking the product

P(x) = (x+3)(x-i)

P(x) = x²-xi+3x-3i

P(x) = x²-(i-3)x- 3i

Hence the required polynomial is

x²-(i-3)x- 3i

Write a word problem about equal groups<br><br><br> and act it out to solve.
lina2011 [118]

Answer:

One scientist was working two molecules:

BF_{3}, SO_{3}

And verified that geometrically speaking, those are trigonal planar molecules made up of an equilateral triangle. He designed both molecules and classified them as Plane dihedral Groups. Was he correct? Why?

Step-by-step explanation:

Yes He was right. Place one atom in the centroid of the equilateral triangle (S or B), and each atom in each vertex(O or F).

We can apply geometric transformations (plane) rotations: R0, R2π/3, R4π/3

(And spatial ones, as R1, R2, R3 180º rotation over each median.)

Composite functions show that this is not an Abelian Group:

R_{1}\circ\:R_{2}=R_{\frac{2\pi}{3}}\\R_{2}\circ\:R_{1}=R_{\frac{4\pi}{3}}\\

Sveta_85 [38]

Answer:

The equations y=10x+250 and y=20x represent the situation.

Step-by-step explanation:

Given that:

Cost to rent the park = $250

Cost per person for t-shirt and snack = $10

Cost of participation = $20

y = cost

x = number of people

Cost for the organization;

y = 10x + 250

Amount generated from people's participation

y = 20x

Hence,

The equations y=10x+250 and y=20x represent the situation.
