Rory is staying in a cabin on a hill 300 feet above sea level. She walks down the hill to the water’s edge. The equation of her average change in elevation over time is e = 300 – 10t, where t is the time in minutes since she left the cabin, and e is her elevation with regard to sea level. Which values are viable points, and what are their values in the table relating t and e?
Accepted Solution
A:
Answer and Step-by-step explanation:
As per the given situation we have following equation
e = 300 - 10t
The elevation and the time can not be in the minus
= t ≥ 0
and
e ≥ 0
As per the provided equation, beginning at the time which is
t = 0
while
elevation which represents e = 300
whereas at the top,
when elevation = 0
So time will be
t = 30 minutes
Therefore, The viable points will be
(0 , 30) and (300 , 0)
