kramer
There is one cake
It is divided among x family members, so each gets:
1/x
The father took 1/5 which is 4 times greater than each one's piece. So:
1/5 = 4(1/x)
1/5 = 4/x
x = 20

Why?

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

How long will it take for an object to fall from 15m?
Solnce55 [7]

The time taken by the object to fall from 15 m on the Mercury which has a gravity of 3.7 m/s² is 10.54 seconds.

<h3>What is kinematics?</h3>

It is the study of the motion of a body without considering mass. And the reason behind them is neglected.

The object is on Mercury and starts falling from rest.

As it is on Mercury there is no air resistance to account for.

Gravity on Mercury is 3.7 m/s².

Then the time taken by the object to fall from 15 m will be given as

\rm t = \sqrt{2gh}\\\\t = \sqrt{2\times 3.7\times 15}\\\\t = 10.5356 \approx 10.54  \ seconds

More about the kinematics link is given below.
