\frac{8}{2z}=\frac{15}{60}\ \ \ \ \ |cross\ multiply\\\\2z\cdot15=8\cdot60\\\\30z=480\ \ \ \ |divide\ both\ sides\ by\ 30\\\\\boxed{z=16}

Evaluate the limit, if it exists. (if an answer does not exist, enter dne.) lim h→0 (5 + h)−1 − 5−1 h
34kurt
\displaystyle\lim_{h\to0}\frac{(5+h)^{-1}-5^{-1}}h=\lim_{h\to0}\frac{\frac5{5(5+h)}-\frac{5+h}{5(5+h)}}h
\displaystyle=-\lim_{h\to0}\frac h{5(5+h)h}
\displaystyle=-\lim_{h\to0}\frac1{5(5+h)}=-\frac1{25}

Alternatively, recall that if f(x)=\dfrac1x, then f'(x)=-\dfrac1{x^2}, and so

f'(5)=\displaystyle\lim_{x\to5}\frac{\frac1x-\frac15}{x-5}

Take h=x-5, so that x=h+5, and we have the original limit. So the limit is equivalent to the value of f'(5), i.e.

f'(5)=-\dfrac1{5^2}=-\dfrac1{25}

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]
