a family swimming pool holds 60m2 of water. the function below gives the cubic
meters of water in the pool, taking into account water lost to evaporation over x
days. how much water does the pool have after 7 days?
f(0) = 60 - 0.187

58.74 cubic meters

Step-by-step explanation:

The function is actually  

Here x is the number of days and the corresponding value of "f(x)" would be the water REMAINING after x days.

Since, we want to figure out how much water (from 60 m^3) is remaining after 7 days, we simply have to plug in x = 7 into the function. Whatever number we get, is the AMOUNT OF WATER REMAINING AFTER 7 DAYS.

So,

Thus, the amount of water remaining in the pool after 7 days is 58.74 cubic meters

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
