Which of the following is a polynomial function in factored form with zeros at –6, –2, and 3?

f(x) = (x – 6)(x – 2)(x + 3)

f(x) = x3 – 5x2 – 12x + 36

f(x) = x3 + 5x2 – 12x – 36

f(x) = (x + 6)(x + 2)(x – 3)

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
