Answer:

Their atomic theory of the elements  

Step-by-step explanation:

The ancient Greeks believed that  all matter consisted of four elements — earth, air, fire, and water

Everything on Earth consisted of these elements in different combinations.

Robert Boyle is best known for his famous Law — p₁V₁ = p₂V₂.

However, he was also an excellent chemist who did many experiments.

He found it was impossible to combine the four Greek elements into any substance.

Boyle found he could decompose many substances into simpler substances, but none of them was a Greek element.  

He therefore rejected the Greek theory.

Almost 150 years before Dalton's atomic theory, Boyle proposed a new definition of an element:  

An element is any substance that cannot be broken into a simpler substance.

Help! Algebra!!!
balandron [24]
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:

125.6m^2

Step-by-step explanation:

Let R be the greater radius and r be the smaller radius

Area of the sidewalk = R^2 - r^2 - This can be the expression

= 3.14

=(R^2-r^2)

=(11^2-9^2)

=(121-81)

= 40

= 3.14 x 40
