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.

Which figure is the image produced by applying the composition T 0,3 o R0,90 to figure R?
Lyrx [107]

We are given original image R.

It is being translated by (0,3) first and then rotated by a positive angle 90 degrees.

Translation by (0,3) represents (x,y) --> (x, y+3) rule.

Positive 90 degree rotation represents, counterclockwise rotation.

The rule for counterclockwise rotation is (x,y) --> (-y,x).

Therefore, final rule for would be

(x,y) --> ( -y,x+3 )

Let us take a coordinate of R on y-axis as (0,-4).

Now if we apply rule (x,y) --> ( -y,x+3 ) we get

(0,-4)  --> (-(-4), 0+3) = (4,3).

Let us check the figure with coordinate (4,3).

We can clearly see that Figure H has transformed coordinate (4,3).

<h3>Therefore, correct option is first option A. figure H.</h3>
