Dada la función f(x)=1+6Sen(2x+π/3) . Halle: Período, amplitud y desfase (1.5 puntos) Dominio y rango de la función (1.5 puntos)
Liula [17]

Dada una ecuación de la forma

<h3>y = A sin(B(x + C)) + D</h3>

Tenemos que:

  • la amplitud es A
  • el periodo es 2π/B
  • el desfase es C (a la izquierda es positivo)
  • el desplazamiento vertical es D

Sabemos que:

f(x)=1+6Sen(2x+π/3)

Y podemos reescribirla como:

f(x)=6Sen(2(x+π/6))+1

Siendo:

  • A = 6 → Amplitud
  • T = 2π/B = 2π/2 = π → Período
  • C = π/6 → Desfase
  • El dominio de un a función trigonométrica es todo el conjunto de los números reales (x ∈ R ).

La imagen de una función trigonométrica de esta forma es:

y ∈ [-A+D,A+D]

y ∈ [-6+1, 6+1]

y ∈ [-5,7]

A ball is drawn randomly from a jar that contains 7 red balls, 5 white balls, and 4 yellow ball. Find the probability of the giv
Furkat [3]

Missing Part:

a. A red ball is drawn

b. A white ball is drawn

Answer:

a. P(Red) = 0.4375

b. P(White) = 0.3125

Step-by-step explanation:

Given

Red = 7

White = 5

Yellow = 4

First, we need to calculate the total

Total = Red + White + Yellow

Total = 7+5+4

Total = 16

Solving (a): Probability of Red.

This is calculated by dividing number of red balls by the total

So:

P(Red) = \frac{Red}{Total}

P(Red) = \frac{7}{16}

P(Red) = 0.4375

Solving (a): Probability of White.

This is calculated by dividing number of white balls by the total

So:

P(White) = \frac{White}{Total}

P(White) = \frac{5}{16}

P(White) = 0.3125
