Aland scalpers mows lawns for at least 3 hours but not more than 6 hours the landscaper can mow 44,000 ft per hour the function f(t)=44,000 represents the number of sq feet the landscaper can mow in t hours what is the practical range of the function

The practical range of the function is all real numbers from 132,000 to 264,000, inclusive

Step-by-step explanation:

The range of a function is the complete set of all f(t).

f(t) = 44,000t

which represent the number of sq feet the landscaper can mow in t hours

t must be at least 3 hours  but not more than 6. Mathematically:

3 ≤ t ≤ 6

These correspond to the following function values:

f(3) = 44,000*3 = 132,000 ft²

f(6) = 44,000*6 = 264,000 ft²

Then:

132,000 ≤ f(t) ≤ 264,000

The fourth one:  Gavin has one and thirteen fourteenths buckets of water. Daven has one and three fourteenths buckets of water. Together they have three and two fourteenths buckets of water.

Step-by-step explanation:

Gavin = 1 13/14

Daven = 1 3/14

1 13/14 + 1 3/14 = 2  16/14

2 16/14 = 3 2/14 = three and two fourteenths
