Answer:

-Why is Democritus important with regard to atomic theory? Democritus developed his atomic philosophy as a middle ground between two opposing Greek theories about reality and the illusion of change. He argued that matter was subdivided into indivisible and immutable particles that created the appearance of change when they joined and separated from others.

-Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. 

-What subatomic particle did JJ Thomson discover? He discovered the electron in 1897.

-In 1913, Neils Bohr proposed a new atomic model known as the Bohr's model, which is patterned after the solar system.

- List the principles of Bohr's model:

a. An electron moves around the nucleus in a circular orbit.

b. An electron's angular momentum in the orbit is quantisized.

c. The change in an electron's energy as it makes a quantum jump from one orbit to another is always accompanied by the emission or absorption of a photon.

- In 1926, Erwin Schrödinger used mathematical equations to describe the likelihood of finding an electron in a certain position. This model is known as the Rutherford Model of an atom.

-In 1932, James Chadwick discovered the neutron.

-Since 1932, the atomic theory has been further enhanced by the concepts that protons and neutrons are made of even smaller units called quarks. The quarks themselves are in turn made of vibrating strings of energy.

-Everything in the universe (except energy) is made up of matter.

-Therefore everything in the universe is made up of atoms.

-An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons and electrons.

The protons and the neutrons make up the centre called the nucleus.

The electrons fly around above the nucleus in a small cloud.

The electrons carry a negative charge and the protons carry a positive charge.

In a normal (neutral) atom the number of protons is the same number of electrons.

Hi!

2^3 ( 2 to the third power or 2 cubed is just 2x2x2) is 8

Let me know if you need anymore help!

Step-by-step explanation:

Using PEMDAS, we need to evaluate what 2^3 equals.

\( {2}^{3} = 2 \times 2 \times 2 = 8\)

Your expression is:

\(9 + (16 - 8) \div 2\)

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

$4500

$4500

$4500

This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:

x^2-2y=3 - (x-2y=3) => x^2-x=0

Then we can factor the resulting equation and find the values of x:

x^2-x=0 => x(x-1)=0 => x=0 or x=1

Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:

x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1

Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:

x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1

Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Answer:

Company B, since 40 > 25 and 40 > 35

Step-by-step explanation:

Company A:

With each window more, price increases by 25

Company B:

15, 55, 95, 135, 175

With each window, the price increases by 40

Company C:

y = 35x + 25

x = number of windows

If x increases by 1, the price increases by 35, therefore, this is the increase per window

Answer:

3/32

Step-by-step explanation:

One approach to doing this probelm is to evaluate all three functions F, G and H at x = 2:

F(2) = 2(2) - 1 = 3

G(2) = 3(2) + 2 = 8

H(2) = (2)^2 = 4

                                                           3/8

Then (F/G)(2) = (3/8), and (F/G/H) = -------- = 3/32

Answer: 5400

Step-by-step explanation: image attached

Answer:

5400

Step-by-step explanation:

we need to calculate the area of big box (prism).

volume = 4 1/2 X 5 X 3 3/4

= 84.375 in³.

volume of small cube = 1/4 X 1/4 X 1/4

= 0.015625 in³.

now we need to find how many of the small ones go into the big one.

84.375/0.015625

= 5400.

Answer:

108

Step-by-step explanation:

a = pi(r^2) is the same as a = 3(6^2).

6 x 6 = 36

36 x 3 = 108

So the answer is 108 cm squared.
