The solution that can be eliminated is (a) the solution –0.2 s can be eliminated because time cannot be a negative value.
The equation is given as:
h(t)) = -16t^2 + 40t + 7
From the question
When h(t) = 0, the values of t are
t = -0.2 and t = 2.7
The t in the function h(t) represents time
As a general rule, time cannot be negative.
This means that the solution t = -0.2 can be eliminated
Hence, the solution that can be eliminated is (a) the solution –0.2 s can be eliminated because time cannot be a negative value.
