Answer:

All Real numbers

Step-by-step explanation:

c(x)= x-3

d(x) = x+3

dc(x)= (x-3)(x+3)

(a+b)(a-b)=(a^2-b^2)

dc(x) = (x^2-9)

x^2-9 is defined for all values of x , And hence the domain of cd(x) will be set of all Real Numbers

La función y = 20000 + 1500x relaciona el valor total a pagar por un servicio de fletes y la distancia recorrida, en kilómetros,
suter [353]

Answer:

Los resultados están debajo.

Step-by-step explanation:

Dada la siguiente información:

y = 20.000 + 1.500x

Siendo:

y= costo total

x= kilometros recorridos

<u>Entonces, si recorrio 20km:</u>

y= 20.000 + 1.500*20

y= $50.000

<u>Ahora, si pago $140.000, cuantos km recorrio:</u>

140.000= 20.000 + 1.500*x

120.000/1.500= x

x= 80km

Find the volume of a scented candle that is in the shape of a cylinder with a diameter of 16 centimeters and a height of 20 cent
Kaylis [27]

Answer:

4021.2 cm³

Step-by-step explanation:

you start by getting the radius, the radius is half the diameter which in this case half of 16 is 8 so 8 is your radius and you already know the height which is 20, now that we have the radius and the height we can start

the formula for finding the volume of a cylinder is πr² · h

so are formula would be π8² · 20 which turns into π64 · 20 which then turns into 1280π or 4021.238...

which you then said we need to round the nearest tenth so 4021.238 to the nearest tenth is 4021.2 cm³
