The board of directors of streamlined airlines has declared a dividend of $4,300,000. the company has 400,000 shares of preferred stock that pay $0.70 per share and 2,750,000 shares of common stock. after finding the amount of dividends due the preferred shareholders, calculate the dividend per share of common stock. (round your answer to the nearest cent if necessary)
The dividend per share of common stock is $1.46.
What is the dividend per share of common stock?The first step is to determine the total value of the dividends that was paid to the preferred stock holders.
Total value = 400,000 x $0.70 = $280,000
The total value of the common stock dividends = $4,300,000 - $280,000 = $4,020,000
Dividend per share = 4,020,000 / 2,750,000 = $1.46

Answer: A translation left 3 units and up 6 units
In order to find the translation of a shape in the graph.
Take particular one point from the original shape: (0, 2)
Take particular one point from the translated shape: (-3, 8)
Let the translation be (x, y)
Original + Translation = Translated Image
(0, 2) + (x, y) = (-3, 8)(x, y) = (-3, 8) - (0, 2)(x, y) = (-3, 6)This implies the shape has been translated 3 units left and 6 units up.

The value of x will be equal to 2.477.
What is a logarithm?The logarithm is the inverse function of exponentiation in mathematics. That is, the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised in order to obtain that number x.
The given expression will be solved as follows;-
[tex]5^{x-2}= 8[/tex]
Taking Log on both sides.
[tex]Log_e 5^{x-2}=Log_e8[/tex]
(x-2) Log5 = Log 8
( x-2) = Log8 / Log 5
(x - 2) = Log 8 - Log 5
(x - 2 ) = Log 3
x-2 = 0.477
x = 2.477

8 Lizzie started a new business that had a profit of $31,124 at the end of the first year. Her
financial advisor estimates her profit will increase by 6% a year. Assuming her advisor is
correct, determine her total profit, to the nearest cent, for the first ten years.
Using an exponential function, it is found that her total profit for the first ten years is of $422,426.72.
What is an exponential function?An increasing exponential function is modeled by:
[tex]A(t) = A(0)(1 + r)^t[/tex]
In which:
A(0) is the initial value.r is the growth rate, as a decimal.In this problem, we have that the initial value and the growth rate are given as follows:
A(0) = 31124, r = 0.06.
Hence the profit function is given by:
[tex]P(t) = 31124(1.06)^t[/tex]
Then, the total profit over the first 10 years is given by:
[tex]\int_{0}^{10} P(t) dt[/tex]
[tex]\int_{0}^{10} 31124(1.06)^t dt[/tex]
[tex]\frac{31124}{\ln{1.06}} \times (1.06)^t|_{t = 0}^{t = 10} = 422,426.72[/tex]
Thus, her total profit for the first ten years is of $422,426.72.

For a science project, billy observed a chipmunk and a squirrel stashing acorns in trees. the chipmunk hid 3 acorns in each tree. the squirrel hid 4 acorns in each tree. they each hid the same number of acorns, although the squirrel needed 2 fewer trees. you are going to investigate the number of acorns that each animal hid.
The number of acorns that each animal hid is 48
What is an Equation ?An equation is formed when two algebraic expressions are equated by an equal sign.
It is asked to calculate the number of acorns that each animal hid.
Total number of acorns hid = number of acorns hid per tree * number of trees
Let T be the number of trees chipmunk used
For chipmunk: = 3*T
For squirrel: = 4*(T-4)
As both the animals hid same number of acorns.
3T = 4(T-4)
3T = 4T - 16
16 = T
Therefore the chipmunk hid 16 * 3 = 48 acorns
and the squirrel hid 4(16-4) = 48 acorns.

A ball is thrown into the air with an upward velocity of 36 ft/s. Its height h in feet after t seconds is given by the function h = −16t2 + 36t + 10. In how many seconds does the ball reach its maximum height? Round to the nearest hundredth if necessary. What is the ball’s maximum height?
The ball's maximum height is 30.25 feet.
What is quadratic equation?A quadratic equation in math is a second-degree equation of the form ax² + bx + c = 0. Here a, b, are the coefficients, c is the constant term, and x is the variable.

How long does it take for the ball to hit the ground?
Here we need to solve the equation:
h(t) = 0 = -16t² + 40t + 4
This represents that the ball hits the ground.
So we just need to solve that quadratic equation, using the general formula we get:
[tex]t = \frac{-40 \pm \sqrt{(40)^2 - 4*4*(-16)} }{2*-16} \\\\t = \frac{-40 \pm 43.1 }{-32}[/tex]
