Answer:
The best estimate for the solution is the ordered pair
Step-by-step explanation:
we have
------> equation A
------> equation B
we know that
using a graphing tool, the solution of the system of equations is the intersection point both graphs
The intersection point is
therefore
The best estimate for the solution is the ordered pair
Notice that the height of the pine cone when it hits the ground is zero. So, to find the tame it takes for the pine cone to hit the ground, we just need to replace the height, 
, with 0 in the function, and solve for time 
:
Since time cannot be negative, the solution is
seconds.
Since 1.5 second is significantly less than 2 seconds, we can conclude that <span>2 seconds is not a reasonable answer to this model.</span>
