Answer:
y = -40x+2600
Step-by-step explanation:
Writing the values as coordinate (m, s)
If after flying for 11 seconds, he is 2160 meters from her, the required coordinate is (11, 2160)
Then at 19 seconds he is 1840 meters, the required coordinate is (19, 1840)
Get the slope;
m = 2160-1840/11-19
m = 320/-8
m = -40
Substitute m = -40 and (11, 2160) into the equations;
y-y0 = m(x-x0)
y -2160 = -40(x-11)
y - 2160 = -40x+440
y = -40x+440 + 2160
y = -40x+2600
Hence the requires equation is y = -40x+2600

Answer:
Options A-C-F
Step-by-step explanation:
we know that
<em>The circumference of a circle is equal to</em>
or
where
D is the diameter and r is the radius
therefore
or
The number pi is the ratio circumference - diameter or is the ratio circumference - 2 times radius
<em>The area of the circle is equal to</em>
therefore
The number pi is the ratio Area - radius squared
Of course there is no way for them to be both correct, since they contradict each other.
Here is how to prove Ray incorrect. 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.
