Select the scenario that correctly represents the given graph.
oa. the charges of a package delivery service change with the weight of a package.
b. the value of a car decreases at a rate of 20% every year.
oc. the vertical distance of a roller coaster from the ground changes with respect to its horizontal distance from the beginning of
the ride
d. the height of an arrow, shot at an upward angle, increases before falling to the ground.

C. The vertical distance of a roller coaster from the ground changes with respect to its horizontal distance from the beginning of the ride.

Step-by-step explanation:

See how the graph is in a "U" shape? That tells us that it first decreases and then goes back up at some point.

The way you would find this answer is to go through each scenario (A, B, C, and D) and think about which thing would make sense to go down and then up.

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
