The amount of garbage, g, produced by a city with population p is given by g=f(p). g is measured in tons per week, and p is measured in thousands of people. the town of tola has a population of 40,000 and produces 13 tons of garbage each week. express this information in terms of the function f. explain the meaning of the statement f(5)=2.

f(40) = 13

f(5) = 2 means that a city with a population of 5000 produces 2 tons of garbage per week.

Explanation:

Hi there!

The amount of garbage per week is 13 tons. Then, G = 13 tons per week.

The population of Tola is 40000 or 40 thousands (p = 40). Then, in terms of the function f:

f(40) = 13

f(5) = 2

f(p) = G

p = population measured in thousands = 5 = 5000 people

G = tons of garbage produced per week = 2  

The expression means that a city with a population of 5000 produces 2 tons garbage per week.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
