Answer:
not sure about the answer, but its asking why does the umbrella sale fluctuate when there is more rain or less rain. divide the numbers vertical to each other then look at the month with the mist compared to the least
I think it is 18.5 because a complete revolution is 360 so you divide 360/45 and you get 8 so then you divide 148/8 and you get 18.5.
1 / (1/6) = x / (2/3)...1 drop to 1/6 dash = x drops to 2/3 dash
cross multiply
(1/6)(x) = (1)(2/3)
1/6x = 2/3
x = 2/3 * 6
x = 12/3 = 4 drops <==
Answer:
y = -x + 1
Step-by-step explanation:
y - y1 = m (x - x1)
y-2 = -1 (x - (-1))
y -2 = -x-1
y = - x -1 + 2
y = -x + 1
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>
