Answer:
48 mililiters.
Step-by-step explanation:
We can find the rate of change using the given table.
The formula of the rate of change is
Where we are gonna use points (3.5, 14) and (4.5, 18). Replacing these coordinates we have
Therefore, the average rate of change is 4 mililiters per hour.
Now, to find the function, we need to use the rate, a pair and the point-slope formula
Therefore, the function which models this table, using the proper variables, is
At last, we need to find the amount of water leaked after 12 hours.
Therefore, after 12 hours it leaks 48 mililiters of water.
