Halla el eje de simetría y el vértice de la parábola de cada función cuadrática. Luego grafica la función cuadrátic con todas sus partes identificadas: eje de simetría, vértice y si es punto máximo o mínimo
1.f(x) = x2 + 2x + 3
2. f(x) = -3x2 + 6x + 5

step-by-step explanation:

15.36 per mile

but forgot to round

i am pretty sure

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
