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

i believe the answer is letter c) 8

step-by-step explanation:

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
