Form a polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3
polet [3.4K]

The polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3 is x^3-3x^2-x+3=0

Step-by-step explanation:

We need to find a polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3.

If -1, 1 and 3 are real zeros, it can be written as:

x= -1, x= 1, and x = 3

or x+1=0, x-1=0 and x-3=0

Finding polynomial by multiply these factors:

(x+1)(x-1)(x-3)=0\\(x+1)(x(x-3)-1(x-3))=0\\(x+1)(x^2-3x-x+3)=0\\(x+1)(x^2-4x+3)=0\\x(x^2-4x+3)+1(x^2-4x+3)=0\\x^3-4x^2+3x+x^2-4x+3=0\\Combining\,\,like\,\,terms:\\x^3-4x^2+x^2+3x-4x+3=0\\x^3-3x^2-x+3=0

So, The polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3 is x^3-3x^2-x+3=0

A circle with circumference 6 has an arc with a 20º central angle.
Ray Of Light [21]

Answer:

length of an arc =1 /3 unit or 0.3unit

Step-by-step explanation:

to calculate the length of an arc, having it in mind that the arc is a portion of the circumference of a circle.

circumference of a circle = 6unit

Ф = 20°

recall,

the formulae for finding the length of an arc

= 2πr(Ф/360)

assuming that r is the radius of the circle

so, the circumference of a circle is given to be = 2πr

6 = 2πr

r = (6/2π)

length of an arc = 2πr(Ф/360)

remember that r = (6/2π)

length of an arc = 2π(6/2π) [20°/360°]

length of an arc =  6 × 20°/360°

length of an arc = 120°/360°

length of an arc = 1/3unit

Please help<br> Solve for x.
Olegator [25]
Sum of interior angles = (n-2) × 180<span> = (5-2) x 180 = 3 x 180 = 540

so
x + 90 + 107 + 144 + 138 = 540
x + 479 = 540
x = 540 - 479
x = 61</span>
