Sabastian Company has 10,000 shares of $100 par, 2% cumulative preferred stock and 50,000 shares of $50 par common stock. The following amounts were distributed as dividends: Year Amount Year 1 $10,000 Year 2 30,000 Year 3 45,000 Determine the dividends per share for preferred and common stock for each year. If required, round your answers to two decimal places. If your answer is zero, please enter "0".

Answers

The  dividends per share for preferred and common stock for each year is year 1 $20,000, $10,000; year 2 $30,000, $0 year 3 $30,000, $15,000.

How to determine the Preferred and common stock?

Year 1

Preference Shares = Number of shares × Par value ×%

Preference Shares = 10,000 ×100 × 2%

Preference Shares = $20,000

Common Shareholders:

Common Shareholders = $20,000 - $10,000

Common Shareholders = $10,000

Year 2

Preference Shares = $30,000

Common Shareholders = $0

Year 3

Preference Shares = $20,000 + ($20,000 - $10,000)

Preference Shares = $20,000 + $10,000

Preference Shares = $30,000

Common Shareholders:

Common Shareholders = $45,000 - $30,000

Common Shareholders = $15,000

Therefore year 1 has the amount of $20,000 as preferred stock and $10,000 as common stock.

The midpoint of AB is (2,7) and point A is located at (5,-3).
What are the coordinates of point B?

Answers

The coordinates of point B =(5,10)

what is coordinates?

Coordinates are a set of values which helps to show the exact position of a point in the coordinates plane.

step - by - step  explanation

5-2 = 3

2-3= -1 = the x coordinate of B

-7-3= -10

-7-10 = -13 = the y coordinate of B

(-1, -13) is the point B

A is 3 to the right of the midpoint ,so B is 5 to the left to the midpoint

A is 10 up from the midpoint so B is 10 down from the midpoint.

so the coordinates of point B is (5,10)

ASAP FREE PONTS! HELP! The linear model represents the height, f(x), of a water balloon thrown off the roof of a building over time, x, measured in seconds. Use the constraints of the real-world situation to predict the height of the water balloon at 15 seconds. Use complete sentences to support your answer.

Answers

The height of the water balloon at 15 seconds based on the potential rupturing effect of the balloon's initial gravitational potential energy on the membrane of the balloon upon impact with the ground and that addition forces are not added, is at the ground level or zero feet.

What is gravitational potential energy?

Gravitational potential energy is the energy possessed by a body by virtue of its elevation above ground level.

The points on the path of the water balloon thrown from the building's roof are;

(0, 4), (2, 7), (7, 5), (6, 4), (9, 1), (9.5, 0)

The location of the water balloon, 9.5 seconds after it is thrown off the roof is therefore at the point, h(9.5) = 0 feet, which can be taken as the ground level or base of the building.

According to Newton's third law of motion, which is a physics or natural law, and which states that all bodies remain at rest or continue perpetually in a straight line unless acted upon by a force.

Given that no additional force is specified after the water balloon is thrown from the building, and that a water balloon can be treated as a large drop of water, where the elastic balloon membrane, represents the surface tension holding the large droplet together, we have that the energy of impact of collision of the balloon when it lands, which is obtained from the initial gravitational potential energy of the water balloon, can potentially rupture the membrane, such that the water is spilled and remains on the floor, well after 9.5 seconds, such that at 15 seconds, the height of the balloon remains at ground level.

The surface area of a prism of heigh H and base of sides a, b, and c is:

The given expressions are 8(t+8) and 8t+8.

What is an equivalent expression?

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

Now, 8(t+8)

Using distributive property a(b+c)=ab+ac, simplify 8(t+8)

That is, 8t+64

Take common factor in 8t+8 is 4(2t+2) and 8t+8=4t+8+4t

The vertices of a figure are F(1, 2), G(3,5),and H(3, 2). Rotate the figure 180° about the origin. Find the coordinates of the image.

Answers

The coordinates of the vertices after the image is rotated about origin will be -

F(1, 2) → F'(-1, -2)

G(3, 5) → G'(-3, -5)

H(3, 2) → H'(-3, -2)

What is rotation of figure?

A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction.

Given are the vertices of a figure as → F(1, 2), G(3,5) and H(3, 2).

Since, it is not given in which direction the figure is rotated, we will consider it to be rotated in anti - clockwise direction about the origin. When we rotate a coordinate point by 180 degrees in counterclockwise direction about the origin, then the point A(x ,y) becomes A'(-x ,-y).

The new coordinates will be -

F(1, 2) → F'(-1, -2)

G(3, 5) → G'(-3, -5)

H(3, 2) → H'(-3, -2)

Therefore, the coordinates of the vertices after the image is rotated about origin will be -

F(1, 2) → F'(-1, -2)

G(3, 5) → G'(-3, -5)

H(3, 2) → H'(-3, -2)
