Aria walked down a trail into a valley. v(d) models aria's vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail. what does the statement v(3)< 3 mean?

When Aria had walked 3km along the trail, her vertical distance from the top of the valley was less than 3 km

Step-by-step explanation:

Remember that V(d) denotes Aria's vertical distance from the top of the valley V after she has walked d kilometers along the trail.

This means that V(3) is Aria's vertical distance from the top of the valley after she has walked 3km.

Therefore, V(3)<3 means that Aria's vertical distance from the top of the valley after she has walked 3km, is less than 3km

In other words, the statement means that when Aria had walked 3km along the trail, her vertical distance from the top of the valley was less than 3km

It means Aria's vertical distance from the top of the valley after walking 3 km along the trail is less than 3 km.

Step-by-step explanation:

Since, Here d represents distance along the trail.

And, V(d) represents the vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail.

If the distance along the trial is 3 km.

That is, d = 3

Then the vertical distance she walked from the top of the valley = V(3)

But According to the question,

V(3) < 3

Her vertical distance from the top of the valley after walking 3 km along the trail is less than 3 km.

In other words, For going 3 km along the trail her vertical distance from the top of the valley is less than 3.

The important thing to notice here is that angle FHG is equal to angle JHK due to vertical angles.  That means we have two angles and a side that are equal to each other.

So the two triangles are congruent due to Angle Side Angle.

The answer is C.
