Answer:

d) all notebooks would fall at the same time

Step-by-step explanation:

One thing you learn in Physics class is that acceleration due to gravity is the same for all objects: their change in speed as a function of time is not dependent upon their weight.

For similar objects (notebooks) falling from desk-top height, the effect of air resistance is probably negligible, and is unlikely to be measurable in a casual experiment of the sort described here.

_____

If you assume heavier objects fall faster, then answer selections b and c both would have to be correct. If you assume there is only one correct answer, it must be d.

Rocío trabaja en una peluquería, le pagan $50 por corte realizado, adicionalmente recibe $25 al día. Si el día miércoles recibió

skad [1K]

Usando conceptos de funciones lineales, se encuentra que hizo 5 cortes.

----------------

Una funcion lineale tiene el seguiente formato:

$y(x) = ax + b$

En que:

a eres lá inclinacion, o sea, lo que es pago por cada corte.
b eres el intercepto, o sea, lo pagamiento fixo por día.

----------------

Pagan $50 por corte realizado, o sea, $a = 50$ .
$25 fixo al día, o sea, $b = 25$

Entonces, la funcion de su recibimiento y, como funcion de su numero de cortes x, es da por:

$y(x) = 25 + 50x$

----------------

Recibió $275, o sea, $y(x) = 275$

Entonces, el numero de cortes es:

$y(x) = 25 + 50x$

$25 + 50x = 275$

$50x = 250$

$x = \frac{250}{50}$

$x = 5$

Realizó 5 cortes.

Subtract the 9.45 from the total cost then divide by 9 to get the cost per ball

If f(x) = (x+1)^-1 and g(x) = x-2, what is the domain of f(x) divided by g(x)

Setler [38]

F(x)=(x+1)^-1

f(x)=1/(x+1) so

f(x)/g(x) is

1/[(x+1)(x-2)]

Since division by zero approaches infinity, it is not a real value, and is said to be undefined. Division by zero is "not allowed", which just really means that it does not have a real value. So in this case x cannot equal -1 or 2 so the domain is:

All real numbers except -1 or 2...which can be expressed as:

(-oo,-1),(-1,2),(2,+oo)
