Bill earns $12 per hour and works at most 40 hours per week. identify the independent and dependent quantity in the situation, and find reasonable domain and range values.

a. amount of money earned; hours worked; 0 to 40; $0 to $480

b. hours worked; amount of money earned; $0 to $480; 0 to 40

c. hours worked; amount of money earned; 0 to 40; $0 to $480

d. amount of money earned; hours worked; $0 to $480; 0 to 40

hours worked(independent); amount of money earned(dependent); 0 to 40(domain); $0 to $480(range)

Step-by-step explanation:

Bill earns $12 per hour and works at most 40 hours per week.

Independent quantity : number of hours worked  every week

Dependent quantity : amount of money earned ,because this amount Bill earns, depends on how much he works.

He does not work more than 40 hours per weak. Means his maximum earnings is dollars(not more than this)

Domain lies between 0 and 40 hours

Range lies between $0 and 480$

So, answer will be :

C - hours worked(independent); amount of money earned(dependent); 0 to 40(domain); $0 to $480(range)

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
