Answer:

C.

Step-by-step explanation:

Hi there!

At first glance, this question may look tricky, but don’t overthink it!

The question states that he has more than 20 coins.

Answer A states that he has exactly 20 coins, which can’t be right because he has more than that!

Answer B states he has less than 20 coins, which isn’t right either.

Answer D is his actual amount of coins plus 20, which can’t be applied here

Answer C states that he has more than 20 coins, so that’s your answer!

I hope this helps! :)

Create your own real-world example of a relation that is a function. Domain: The set of Range: The set of
ivanzaharov [21]

Answer:

C(t)=5000 -10t

Step-by-step explanation:

There are many examples in the real world of relationships that are functions.

For example, imagine a tank full of water with a capacity of 5000 liters, this tank has a small hole, by which 10 liters of water are lost every hour.

If we call C the amount of water in the tank as a function of time, then we can write the following equation for C:

C(t)=C_{0}-at\\

Where:

C (t): Amount of water in the tank as a function of time

C_{0}: Initial amount of water in the tank at time t = 0

a: amount of water lost per hour

t: time in hours

Then the equation is:

C(t)=5000 -10t

The graph of C (t) is a line of negative slope. This relation is a function since for each value of t there is a single value of C.

Its domain is the set of all positive real numbers t between [0,500]

Because the time count starts at t = 0 when the tank is full and ends at t = 500 when empty

Its Range is the set of all positive real numbers C between [0,5000] Because the amount of water in the tank can never be less than zero or greater than 5000Litres
