A piece of equipment costs $30,000, and is expected to generate $8,500 of annual cash revenues and $1,500 of annual cash expenses. The disposal value at the end of the estimated 10-year life is $3,000. Ignoring income taxes, the payback period is:.
Answer:
C. 4.29 years
Explanation:
The computation of the payback period is shown below:
Payback period = Initial investment of the equipment ÷ Cash flows
where,
Initial investment = $30,000
And, the cash flows is
= $8,500 - $1,500
= $7,000
So the payback period is
= $30,000 ÷ $7,000
= 4.29 years
By dividing the initial investment by the cash flows we can get the payback period and the same is applied above.

Which correctly lists the three features shown in the photo? folds, strike-slip faults, and anticlines anticlines, synclines, and folds synclines, normal faults, and strike-slip faults normal faults, folds, and anticlines.
Anthe answer is A
Explanation:
The correct list of the three features shown in the photo are folds, strike-slip faults, and anticlines. The correct option is A.
What are folds?On a geological timescale, modern folds are those that first appeared in the Tertiary Period (between 65 million and 2.5 million years ago). Geological formations known as faults are the result of internal forces that are inclined or vertical (top-down).
The transcurrent fault, which is also known as a horizontal fault, develops when there is movement in the horizontal plane between two blocks.
It is more prevalent in regions where two tectonic plates converge since these zones also experience horizontal movement. When two or more of the tectonic plates of Earth are forced together, fold mountains are formed.
Therefore, the correct option is A, folds, strike-slip faults, and anticlines.

The fifth term of a geometric sequence is 781. 25. Each term of the sequence is of the value of the following term. Which recursive formula represents the situation?.
Answer: an = 5an-1
Explanation: Given fifth term of a geometric sequence is 781.25.
a5 = 781
Also, each previous term is 1/5 of the value of the current term.
Therefore, common ratio would be 5.
But we just need to find the recursive formula .
Recursive formula of a geometric sequence is given by
Plugging value of r in above formula, we get
Therefore, recursive formula would be represents the situation.
The recursive formula that represents the situation is: [tex]t_n = a^{(3/4)} * 781.25^{(1/4)} * n^{(1/4)}[/tex].
What is recursive formula?A recursive formula is one that defines any term in a sequence in terms of the term(s) before it.
Let the first term of the geometric sequence be 'a' and the common ratio be 'r'.
We are given that the fifth term is 781.25, so we can write:
a * [tex]r^4[/tex] = 781.25
We also know that each term is the value of the following term, so we can write the recursive formula:
t_n = r * t_(n-1)
Where t_n is the nth term of the sequence and t_(n-1) is the previous term.
To express the recursive formula in terms of 'a' and 'r', we can use the formula for the nth term of a geometric sequence:
[tex]t_n = a * r^{(n-1)[/tex]
Substituting the recursive formula, we get:
[tex]r * t_{(n-1)} = a * r^{(n-1)[/tex]
Dividing both sides by r^(n-1), we get:
[tex]t_{(n-1)} = a * r^{(n-2)[/tex]
So the recursive formula in terms of 'a' and 'r' is:
t_n = r * t_(n-1)
[tex]= r * (a * r^{(n-2)})\\\\= a * r^{(n-1)[/tex]
Now we can substitute the value of the fifth term (781.25) to solve for 'a' and 'r':
a * [tex]r^4[/tex] = 781.25
Dividing both sides by a, we get:
[tex]r^4[/tex]= 781.25/a
Taking the fourth root of both sides, we get:
r = [tex](781.25/a)^{(1/4)[/tex]
Substituting this value of 'r' into the recursive formula, we get:
[tex]t_n = a * ((781.25/a)^{(1/4)}){^(n-1)}\\\\= a^{(3/4)} * 781.25^{(1/4)} * n^{(1/4)}[/tex]
Therefore, the recursive formula that represents the situation is:
t_n = a^(3/4) * 781.25^(1/4) * n^(1/4)

A mixture of iron, salt, and sand can be separated using a magnet, water, a filter, and a hot plate. This separation _____.
Answer:
i think mixture
Explanation:
sorry if it wrong(tried my best)
Answer:
This is an example of a mixture that can be separated with simple separation techniques based on the physical properties of the mixtures. Magnetism, and filtration and evaporation
Iron is a magnetic material, but salt and sand are not, therefore, the iron can be separated from the mixture with the use of a magnet.
Salt and sand are mixable. Salt is soluble in water, but sand is not. Therefore by adding the sand and salt to water, the salt will dissolve,in the water(solvent) to form a salt solution. But the sand can be separated out of the solution by filtration with the filter paper inserted into a funnel which allows the salt solution to pass through while restricting the sand.
The sand would be removed by the filter paper, while the solution passes through.
The salt solution and some sand residues are placed in an evaporating dish and heated at low temperatures. The water from the solution evaporates, leaving the salt behind.
A rock is projected from the edge of the top of a building with an initial velocity of 12. 2 m/s at an angle of 63° above the horizontal. The rock strikes the ground a horizontal distance of 25 m from the base of the building. Assume that the ground is level and that the side of the building is vertical. What is the time?.
The rock travels a horizontal distance x after time t of
x = (12.2 m/s) cos(63°) t
If it hits the ground 25 m away from where it was thrown, then for some time t we have
25 m = (12.2 m/s) cos(63°) t
Solve for t :
t = (25 m) / ((12.2 m/s) cos(63°))
t ≈ 4.5 s

Fecundity is the biological capacity of an organism to conceive a child - in conjunction with another organism. For this to occur it is necessary that the man and the woman be fertile, that is, they have fertility. A person's fertility is measured by the number of ovules / seeds that can be fertilized. After fertilization, the fetus grows in the gestational process and becomes a baby.
The correct word from the list that best fits the definition of the biological capability to bear children is fecundity. The correct option is E.
What is childbearing?Women can theoretically become pregnant and give birth from puberty, when they begin having periods, to menopause, when they cease having them. The reproductive years of the average woman last from 12 to 51 years.
The biological ability of one organism to conceive a child in collaboration with another creature is known as fecundity. Both the man and the woman must be fertile, or have fertility, for this to happen.
The quantity of ovules or seeds that can be fertilized is used to determine a person's fertility. The fetus develops during the gestational period after conception to become a baby.
Therefore, the correct option is E. Fecundity.

Two football players are running toward each other. One football player has a mass of 105 kg and is running at 8. 6 m/s. The other player has a mass of 90 kg and is running at -9. 0 m/s. What is the momentum of the system after the football players collide? 93 kg · m/s 1,713 kg · m/s. 810 kg · m/s. 903 kg · m/s.
The correct answer is P = 1740 kg · m/s, we got this answer by applying the momentum expression which is P = Δ(mv), based on the fact that the mass is not constant
Given data
Mass of Player one = 105kg
Mass of Player two = 93Kg
The Velocity of Player one = 8.6m/s
The Velocity of Player two = -9.0m/s (the negative sign indicates the opposite direction to player one)
Applying Newton’s Second Law in Terms of Momentum because the mass is not constant
When Newton’s second law is expressed in terms of momentum, it can be used for solving problems where mass varies,
We also want to assume that the players stuck together after the collision
An inelastic collision, in contrast to an elastic collision, is a collision in which kinetic energy is not conserved due to the action of internal friction.
