Erica walked down a trail into a valley.

v(d)v(d)v, left parenthesis, d, right parenthesis models erica's vertical distance from the top of the valley (in kilometers) after walking ddd kilometers along the trail.

what does the statement v(2)=tv(2)=tv, left parenthesis, 2, right parenthesis, equals, t mean?

Erica's vertical distance from the top of the valley (in kilometers) after walking 2 kilometers along the trail is T.

Step-by-step explanation:

It is given that V(d) models Erica's vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail.

We need to find the meaning of V(2)=T.

On comparing V(d) and V(2), we get d=2.

Since V(d) models Erica's vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail, therefore V(2) models Erica's vertical distance from the top of the valley (in kilometers) after walking 2 kilometers along the trail.

It means Erica's vertical distance from the top of the valley (in kilometers) after walking 2 kilometers along the trail is T.

i not know

step-by-step explanation:

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
