Find a polynomial function f in standard form with zeros 3i, -2, 1

Mathematics
1 answer:
yanalaym [24]3 years ago
3 0
The first thing to remember is that when you have a zero of 3i, you will also have a zero of -3i. This is because of the way imaginary solutions are created (taking the square root of a negative number). When you take the sqrt you get TWO answers.
The factors for these zeros are (x - 3i)(x+3i)(x+2)(x-1)
When you multiply the factors, the polynomial will be:
x^4 + x^3 + 7x^2 + 9x - 18

Given: Quadrilateral PQRS is a rectangle. Prove: PR = QS
lord [1]

Answer:

Given: Quadrilateral P QR S  is a rectangle.

To prove :PR= Q S

Construction : Join PR and Q S.

Proof: In Rectangle PQRS, and

→ taking two triangles PSR and Δ QRS

  1. PS = Q R

  2.  ∠ PS R  = ∠ Q RS  [Each being 90°]

  3. S R is common.

→ ΔP SR ≅  Δ Q RS → [Side-Angle-Side Congruency]

∴ PR =Q S [ corresponding part of congruent triangles ]

Hence proved.

B = 54°, b=15, c=<br> c = ? (Round answers to<br> the nearest hundredth.)
zaharov [31]

Answer:

18.54

Step-by-step explanation:

sine is opposite/hypotenuse, and you have opposite (b=15), so use that

sin(54) = 15/c

c = 15/sin54

then use calculator

c = 18.54
