Time (t)Elevation (e)Rory is staying in a cabin on a hill 300 feet above sealevel. She walks down the hill to the water's edge. Theequation of her average change in elevation over timeis e = 300 - 10t, where t is the time in minutes sinceshe left the cabin, and e is her elevation with regard tosea level. Which values are viable points, and what aretheir values in the table relating t and e?-2a=ab =<<



Answer :

The function for the elevation or height of Rory is given by :

[tex]e=300-10t[/tex]

You just need to substitute the values of t to the function of elevation to get the height or elevation above the sea level.

When t = -2

e = 300 - 10(-2)

e = 300 + 20

e = 320

So a = 320

But since there is no negative time, t = -2 is not viable

When t = 3.5

e = 300 - 10(3.5)

e = 300 - 35

e = 265

So b = 265

When t = 30

e = 300 - 10(30)

e = 300 - 300

e = 0

So c = 0
