A group of volunteers is spending a week cleaning up the trails in the Hudson highlands on day 2 the volunteers begin at the point on the trail were they ended the day before. the graph shows their elevation, in feet, as a function of the number of hours they work to clean the trails.

Complete question:

A group of volunteers is spending a week cleaning up the trails in the Hudson highlands on day 2 the volunteers begin at the point on the trail were they ended the day before.the graph shows their elevation,in feet,as a function of the number of hours they work to clean the trails.

Elevation (ft)

800

O1 2 3 4 5 6 7 8

Time (h)

a. What does the ordered pair (1, 1000) on the graph represent?

b. The graph begins at 720 on the y-axis. What does this value represent? Is this

the rate of change or the initial value?

c. By how many feet does the elevation increase for one hour of work? What does

this value represent, rate of change or initial value?

d. What is the equation that represents this function?

Solution:

a. We were at 1000 ft. in elevation b in 1 hour. This meaning reflects that they began at an elevation of 720 ft.

That's the original interest.

c. The elevation increases by 280 per hour. Um, ft. That's the pace of transition.

d.  280x = y

the statement that best explains why the tenth amendment reserves some rights and powers to states is that the framers believed in the principle of federalism. this principle says that some powers are in the hands of a centralized national government, while others are reserved for the governments of several states.
