Answer:
Please check the explanation.
Step-by-step explanation:
Given the polynomial function
Let us determine the factors by solving
Using the zero factor principle:
if 
Thus, (x+2) (x+4) and (x-4) are the factors of the polynomial function.
Therefore,
YES
And (x-2) (x+6) are not the factors of the polynomial function.
Therefore,
YES
$0.42 I think that is the answer
Answer:
Step-by-step explanation:
The equation for this free fall problem is
where h(t) is the height of the pebble from the ground at any time t. If we are looking for the time it takes the pebble to hit the ground, knowing that at ground level the height is 0, we set the quadratic equal to 0 and solve for t:
and
and
so
t = -8, 8
Since time will never be negative,
t = 8 seconds
