Re-arrange the terms from greatest degree to smallest degree.

We can solve it by applying quadratic formula,

Here a = –16, b = 48, c = 288




Now, write find two t's using plus and minus operation.


t = –3 (or) t = 6
We cannot write time is negative. so neglect t = –3.
Therefore t = 6.
Hence 6 sec can take penny to strike the ground.

Answer:
≈ 8.07 mg
Step-by-step explanation:
Given
f(x) = 12
Substitute x = 1 into f(x) , that is
f(2) = 12(0.82)² = 12 ×0.6724 ≈ 8.07 mg
The roots of the parabola is where the x-intercepts are so the answer is x=-1 and x= 5
