Thet contradict each other, that's why both of them are incorrect.
<span>Suppose that a polynomial has four roots: s, t, u, and v. If the polynomial were evaluated at any of these values, it would have to be zero. Therefore, the polynomial can be written in this form.
p(x)(x - s)(x - t)(x - u)(x - v), where p(x) is some non-zero polynomial
This polynomial has a degree of at least 4. It therefore cannot be cubic.
Now prove Kelsey correct. We have already proved that there can be no more than three roots. To prove that a cubic polynomial with three roots is possible, all we have to do is offer a single example of that. This one will do.
(x - 1)(x - 2)(x - 3)
This is a cubic polynomial with three roots, and four or more roots are not possible for a cubic polynomial. Kelsey is correct.
Incidentally, if this is a roller coaster we are discussing, then a cubic polynomial is not such a good idea, either for a vertical curve or a horizontal curve. I hope this helps</span><span>

Answer:
The answer is would be 1.2 or 1.22
Answer:
10.55%
Step-by-step explanation:
Given:
Initial weight of the new born baby = 3,874 grams
final weight of the baby = 3,465 grams
Now,
the current percentage of the weight loss will be calculated as:
Weight loss percentage = 
%
on substituting the respective values, we get
Weight loss percentage = 
%
or
Weight loss percentage = 10.55%
