Erica walked down a trail into a valley.V(d) models Erica's vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail.What does the statement V(2)=T mean?Choose 1 answer:(A) Erica's vertical distance from the top of the valley was the same after she had walked 2 km and after she had walked T kilometers.(B) After she had walked 2 km along the trail, Erica's vertical distance from the top of the valley was equal to T kilometers.(C) After she had walked T kilometers along the trail, Erica's vertical distance from the top of the valley was equal to 2 km
Q. Erica walked down a trail into a valley.V(d) models Erica's vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail.What does the statement V(2)=T mean?Choose 1 answer:(A) Erica's vertical distance from the top of the valley was the same after she had walked 2 km and after she had walked T kilometers.(B) After she had walked 2 km along the trail, Erica's vertical distance from the top of the valley was equal to T kilometers.(C) After she had walked T kilometers along the trail, Erica's vertical distance from the top of the valley was equal to 2 km
Function V(d): Understand the function V(d).The function V(d) represents Erica's vertical distance from the top of the valley after walking d kilometers along the trail. We need to interpret what V(2)=T means in this context.
Interpret V(2)=T: Interpret V(2)=T.The statement V(2)=T means that when Erica has walked 2 kilometers along the trail, her vertical distance from the top of the valley is T kilometers. This is a direct application of the function V(d) where d is replaced by 2.
Eliminate incorrect choices: Eliminate incorrect choices based on the interpretation.(A) This choice suggests that Erica's vertical distance is the same after walking 2 kilometers and T kilometers, which is not what V(2)=T implies.(B) This choice correctly interprets that after walking 2 kilometers, Erica's vertical distance from the top is T kilometers.(C) This choice incorrectly suggests that after walking T kilometers, Erica's vertical distance is 2 kilometers, which is not stated by V(2)=T.
