What is the domain of f(x) = (1/3)^x ?
olya-2409 [2.1K]

Answer:

B

Step-by-step explanation:

There isn't any number that x can't be. Start with a graph to show how this could be so.

It is easy to see that x > 0 gives a line that goes very near the x axis. It is not quite so easy to see that it never touches the x axis. But if you recreate the graph in  Desmos, you will see that is true if you spread the x's out.

It is not quite so easy to see that when x<0 the graph tips upward very quickly but again if you move the values of the axis around you will see there is no value that x cannot be.

Maria necesita un par de zapatos de tacon para un evento de gala y ya vio tres pares que le gustaron mucho cada uno cuesta $500,
Art [367]

Answer:

Mária debe trabajar mínimo 9 horas si quisiera tener la cantidad para pagar cualquiera de los pares de zapatos.

Step-by-step explanation:

Tenemos que calcular la cantidad de horas que tiene que trabajar María para alcanzar la cantidad de dinero necesaria para comprar alguno de los pares. La cantidad de dinero que Mária gana por trabajar x horas es 50.50*x. La cantidad total de dinero que tiene María está dada por 200+50.50*x (se le suma la cantidad que tiene ahorrada). Luego, basta con que esta cantidad sea mayor o igual al precio de cada par de zapatos.

Para hacerlo de manera más general, considerando unos zapatos que cuestan y, tenemos la siguiente inecuación

200+50.5x \geq y

Restando 200 a ambos lados y dividiendo por 50.5 obtenemos que

x \geq \frac{y-200}{50.5}

Basta reemplazar y por el valor de cada par de zapatos, para obtener su x correspondiente.

Si y = 500, entonces x \geq 5.94. Es decir, debe trabajar mínimo 6 horas.

Si y = 580 entoncesx \geq 7.52. Es decir, debe trabajar mínimo 8 horas

si y = 620 entoncesx\geq 8.31. Es decir, debe trabajar mínimo 9 horas.

Es decir que si quisiera tener la cantidad para pagar cualquiera de los pares, debe trabajar mínimo 9 horas.

WHOEVER ANSWERS CORRECTLY AND FAST GETS BRAINLIEST!!!!!!!!!!!!!!!!!!!!
hammer [34]

Answer:

r = 32,546.69 * 1.03^t

Step-by-step explanation:

33,523.09/32,546.69 = 1.03

34,528.78/33,523.09 = 1.03

35,564.65/34,528.78 = 1.03

The common ratio between values is 1.03.

The initial value is 32,546.69

The is exponential growth with initial value 32,546.69 and a growth factor of 1.03.

Equation:

y = a(1 + i)^t

r = 32,546.69 * 1.03^t
