Answer:
Step-by-step explanation:
By choosing the LIFO method for inventory, the following items would be decreased (compared to what would have happened if they chose to use FIFO):
Net income
Taxes payable
Total assets
Owner's equity
This is because the LIFO method results in higher cost of goods sold and lower ending inventory, which in turn decreases net income and taxes payable. Lower ending inventory also decreases total assets and owner's equity.
The items that would be decreased by the choice of LIFO (compared to what would have happened if they chose to use FIFO) are Ending inventory and Net profit
What is the unitary method?
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
We are given that;
Inventory costs in 2012 were rising
Now,
LIFO stands for last-in, first-out, and FIFO stands for first-in, first-out. These are two ways of assigning costs to the units of inventory that you sell. FIFO assumes that you sell the oldest units first, while LIFO assumes that you sell the newest units first1.
The choice of LIFO or FIFO has implications on a company’s financial statements as this decision impacts the value of inventory, cost of goods sold, and net profit2. If inventory costs are rising during a period, then LIFO will result in a lower value of ending inventory, a higher cost of goods sold, and a lower net profit compared to FIFO1.
Therefore, by unitary method the answer will be Ending inventory and Net profit

A bank requires that the Dotkoms pay their homeowner's insurance, property taxes, and
mortgage in one monthly payment to the bank. If their monthly mortgage payment is $1,711.22,
their semi-annual property tax bill is $3,239, and their annual homeowner's insurance bill is
$980, how much do they pay the bank each month?
Answer: $2,162.06
Step-by-step explanation:
To calculate the total monthly payment to the bank, we need to add up the monthly mortgage payment, the monthly portion of the semi-annual property tax bill, and the monthly portion of the annual homeowner's insurance bill.
First, we need to find the monthly portion of the semi-annual property tax bill. To do this, we divide the semi-annual property tax bill by 6 (since there are 6 months in half a year):
Monthly property tax payment = Semi-annual property tax bill / 6
Monthly property tax payment = $3,239 / 6
Monthly property tax payment = $539.83
Next, we need to find the monthly portion of the annual homeowner's insurance bill. To do this, we divide the annual homeowner's insurance bill by 12 (since there are 12 months in a year):
Monthly homeowner's insurance payment = Annual homeowner's insurance bill / 12
Monthly homeowner's insurance payment = $980 / 12
Monthly homeowner's insurance payment = $81.67
Now we can add up the monthly mortgage payment, the monthly property tax payment, and the monthly homeowner's insurance payment to find the total monthly payment to the bank:
Total monthly payment = Monthly mortgage payment + Monthly property tax payment + Monthly homeowner's insurance payment
Total monthly payment = $1,711.22 + $539.83 + $81.67
Total monthly payment = $2,332.72
Therefore, the Dotkoms pay the bank $2,332.72 each month.
Answer:
Step-by-step explanation:
Using proportions, it is found that they pay the bank $2332.72 each month.
What is a proportion?
A proportion is a fraction of a total amount.
Using proportions, it is found that they pay the bank $2332.72 each month.
What is a proportion?
A proportion is a fraction of a total amount.
Their payments are given by:
Monthly mortgage of $1,711.22.
Semi-annual property tax bill is $3,239, that is, it is paid every 6 months, hence 3239/6 = $539.83.

(t)=S(t)(1−S(t))
iv.
S ′
(t)=−S(−t)
The derivative of S(t)= 1+e −t is S'(t) = S(t)(1 - S(t)). So, the correct answer is (iii).
To find S'(t), we can use the chain rule:
S'(t) = (d/dt) [1 + e^(-t/2)]^-2 * d/dt [1 + e^(-t/2)]
Using the chain rule again for the second derivative:
d/dt [1 + e^(-t/2)] = (-1/2)e^(-t/2)
d/dt [1 + e^(-t/2)]^-2 = -2(1 + e^(-t/2))^-3 * (-1/2)e^(-t/2) = (1/2) e^(-t/2) / (1 + e^(-t/2))^3
Substituting into the expression for S'(t), we have:
S'(t) = [(1/2) e^(-t/2) / (1 + e^(-t/2))^3] * [1 - (1/2)e^(-t/2)]
S'(t) = (1/2) e^(-t/2) / (1 + e^(-t/2))^3 * [2 - e^(-t/2)]
S'(t) = e^(-t/2) / (1 + e^(-t/2))^3 * [2 - e^(-t/2)]
Taking the derivative of S(t), we have:
S'(t) = e^(-t/2) / (1 + e^(-t/2))^2
Comparing this to the given choices, we can see that:
S'(t) = S(t) is not true, since S(t) = 1 + e^(-t/2) and S'(t) is a different function.
S'(t) = (S(t))^2 is not true, since (S(t))^2 = (1 + e^(-t/2))^2 is a different function from S'(t).
S'(t) = S(t)(1 - S(t)) is true, since we can substitute S(t) and S'(t) from above and simplify:
S'(t) = e^(-t/2) / (1 + e^(-t/2))^3 * [2 - e^(-t/2)]
S(t)(1 - S(t)) = [1 + e^(-t/2)] * [1 - (1 + e^(-t/2))] = e^(-t/2) / (1 + e^(-t/2))
Therefore, S'(t) = S(t)(1 - S(t)) is true.
S'(t) = -S(-t) is not true, since S(-t) = 1 + e^(t/2) and -S(-t) is a different function from S'(t).
So the correct choice is (iii): S'(t) = S(t)(1 - S(t)).

2 cities are 210 miles apart. If the distance on the map is 3 1/4 inches, find the scale of the map
The scale of the map = 682.5.
How would you define distance in one sentence?We kept a safe distance and followed them. She perceives a separation between her and her brother that wasn't there before. Although they were previously close friends, there was now a great deal of gap between them.
We must calculate the ratio of the distance shown on the map to the real distance between the cities in order to ascertain the scale of the map.
We are aware that there are 210 miles separating the two cities. Let x represent the precise location of this distance on the map. From that, we may establish the ratio:
Actual distance / Map Distance = 210 / x
The distance on the map is indicated as 3 1/4 inches, which is also known as 13/4 inches. When we enter this into the percentage, we obtain:
Actual distance divided by (13/4) = 210 / x
We can cross-multiply and simplify to find x's value:
Actual distance: 682.5 = x * 210 x = 3.25 when 210 * (13/4) Equals x.
Consequently, 3.25 inches on the map represent the actual distance between the cities. We can write: To determine the map's scale:
Actual distance divided by 1 inch on the chart equals 210 miles.
When we replace the values we discovered earlier, we obtain:
1 / 210 = 3.25 / scale
If we solve for the scale, we obtain:
scale = 682.5.

if y is given and you need to find third derivative of y (given as y'''), what are the steps: explain what one needs to do and say it in your words.
The steps for finding out the third derivative of y (given as y''') are explained and given below.
To find the third derivative of y (y'''), you would need to differentiate the function y three times with respect to the independent variable. Here are the steps:
Start by differentiating y once to get the first derivative, y'.
Differentiate y' again to get the second derivative, y''.
Finally, differentiate y'' to get the third derivative, y'''.
You can use the chain rule, product rule, quotient rule, and other differentiation rules as needed to find each derivative.
Here's an example of finding the third derivative of y for the function y = x^4 + 2x^3 - 5x:
y' = 4x^3 + 6x^2 - 5
y'' = 12x^2 + 12x
y''' = 24x + 12

Using the two points you have plotted, draw the parabola. It should look like a downward-facing curve opening at the vertex (0, 7).
What is parabola?
A parabola is a symmetrical, U-shaped curve that is formed by the graph of a quadratic function.
Assuming you meant [tex]f(x) = -x^2 + 7[/tex], here's how you can graph the parabola using the parabola tool:
Find the vertex
The vertex of the parabola is located at the point (-b/2a, f(-b/2a)), where a is the coefficient of the [tex]x^2[/tex] term and b is the coefficient of the x term. In this case, a = -1 and b = 0, so the vertex is located at the point (0, 7).
Plot the vertex
Using the parabola tool, plot the vertex at the point (0, 7).
Plot a second point
To plot a second point, you can choose any x value and find the corresponding y value using the quadratic function. For example, if you choose x = 2, then [tex]f(2) = -2^2 + 7 = 3[/tex]. So the second point is located at (2, 3).

There are two coins. One of them is a biased coin such that P (head): P (tail) is 1 : 3 and the other coin is a fair coin. A coin is selected at random and tossed once. If the coin showed head, then find the probability that it is a biased coin.
Answer:
Step-by-step explanation:
Let B be the event that the selected coin is biased, and F be the event that the selected coin is fair. Let H be the event that the coin toss shows a head.
We want to find P(B|H), the probability that the selected coin is biased given that the coin toss shows a head. By Bayes' theorem, we have:
P(B|H) = P(H|B) * P(B) / P(H)
We know that P(H|B) = 1/4 (since the biased coin has a probability of 1/4 of showing a head), and that P(B) = 1/2 (since there are two coins, one of which is biased).
To find P(H), we can use the law of total probability:
P(H) = P(H|B) * P(B) + P(H|F) * P(F)
P(H) = (1/4) * (1/2) + (1/2) * (1/2)
P(H) = 3/8
Putting it all together:
P(B|H) = P(H|B) * P(B) / P(H)
P(B|H) = (1/4) * (1/2) / (3/8)
P(B|H) = 1/3
Therefore, the probability that the selected coin is biased given that the coin toss shows a head is 1/3.

What is the scale of the map?A scale in a map is a relation that tells us how many units each unit in the map represents. In this case, we know that the distance between two points A and B on the map is 5 inches, while the actual distance between these two places is 250 miles.
Then we start with the relation:
5 inches = 250 miles.
But to get the scale of the map we need to see how many miles one inch represents in the map, then we can divide both sides of the equation by 5 to geT:
5 in = 250 mi

B. if the number of pupils taken the examination is 46, find the value of x
If we round up, we get x = 12, which means that 12 students took history and 36 students took mathematics.
What is venn diagram?A Venn diagram is a graphical representation of sets, often used to show relationships between different sets of data. It consists of one or more circles, where each circle represents a set. The circles are usually overlapping to show the relationships between the sets. The region where the circles overlap represents the elements that belong to both sets. The non-overlapping parts of each circle represent the elements that belong to only one of the sets.
Here,
A. To illustrate the data on a Venn diagram, we need to draw two overlapping circles, one for history and one for mathematics. We can label the regions as follows:
The region where the circles overlap represents the students who took both history and mathematics.
The region outside both circles represents the students who did not take either history or mathematics.
The region within the history circle but outside the mathematics circle represents the students who took history but not mathematics.
The region within the mathematics circle but outside the history circle represents the students who took mathematics but not history.
In this diagram, let's assume that x students took history and 3x students took mathematics. Then the total number of students who took the examination is x + 3x = 4x. We can label the regions on the diagram accordingly:
The region where the circles overlap represents the students who took both history and mathematics. Since there are 3x students who took mathematics, and all of them are included in the overlap region, the number of students who took both is 3x.
The region outside both circles represents the students who did not take either history or mathematics. Since there are 46 students in total, and 4x of them took the examination, the number of students who did not take either is 46 - 4x.
The region within the history circle but outside the mathematics circle represents the students who took history but not mathematics. Since x students took history, and 3x took mathematics, the number of students who took history but not mathematics is x - 3x = -2x. However, since we cannot have a negative number of students, we can assume that this region is empty.
The region within the mathematics circle but outside the history circle represents the students who took mathematics but not history. Since there are 3x students who took mathematics, and some of them also took history, the number of students who took mathematics but not history is 3x - 3x = 0. Therefore, this region is also empty.
B. We know that the total number of students who took the examination is 46. Therefore, we have:
x + 3x = 46
4x = 46
x = 11.5
However, since x represents the number of students who took history, it must be a whole number. Therefore, we can round x up or down to the nearest whole number. If we round down, we get x = 11, which means that 11 students took history and 33 students took mathematics.

Decide if the function is an exponential growth function or exponential decay function, and describe its end behavior using
limits.
Y=(1/6) ^-x
Answer:
The given function is an exponential growth function, not an exponential decay function because as the exponent x increases, the value of y also increases instead of decreasing.
To describe its end behavior using limits, we need to find the limit of the function as x approaches infinity and as x approaches negative infinity.
As x approaches infinity, the exponent -x approaches negative infinity, and the base (1/6) is raised to increasingly larger negative powers, causing the function to approach zero. So, the limit as x approaches infinity is 0.
As x approaches negative infinity, the exponent -x approaches infinity, and the base (1/6) is raised to increasingly larger positive powers, causing the function to approach infinity. So, the limit as x approaches negative infinity is infinity.
Therefore, the end behavior of the function is that it approaches zero as x approaches infinity and approaches infinity as x approaches negative infinity.

Divide 240g in the ratio 5 4 3
Step-by-step explanation:
240g divided in ratios.
divide 240g in the ratio 5:4:3
To divide 240g in the ratio 5:4:3, we need to determine the amount of each part of the ratio.
First, we need to find the total number of parts in the ratio, which is 5 + 4 + 3 = 12.
Next, we divide the total amount (240g) by the total number of parts (12) to find the value of one part:
240g ÷ 12 = 20g
Therefore, one part of the ratio is equal to 20g.
To find the amount of each part of the ratio, we can multiply the value of one part by the corresponding number in the ratio.
The amounts are:
5 parts: 5 × 20g = 100g
4 parts: 4 × 20g = 80g
3 parts: 3 × 20g = 60g
Therefore, to divide 240g in the ratio 5:4:3, we need 100g, 80g, and 60g for each part of the ratio, respectively.
Answer
100g , 80g , 60g
Step-by-step explanation:
Ratio:Ratio = 5 : 4 : 3
Let the unit share be 'x'.
So, three shares are 5x, 4x and 3x.
Total weight = 240 g
Total shares = 5x + 4x + 3x = 12x
Sum of all the shares equal to the total weight.
12x = 240g
x = 240 ÷ 12 = 20
The value of unit share is 20 g. From this we can find the weight of each share.
5x = 5 * 20 = 100g
4x = 4 * 20 = 80 g
3x = 3 * 20 = 60 g

The open circle at 3 indicates that 3 is not included in the solution set. This inequality can be read as "X is less than 5" or "X is strictly less than 5."
What is expression?In mathematics, an expression is a combination of numbers, symbols, and operators that represents a value. Expressions can be as simple as a single number or variable, or they can be complex combinations of mathematical operations. For example, 2 + 3 is a simple expression that represents the value 5, while (2 + 3) x 4 - 1 is a more complex expression that represents the value 19. Expressions can be evaluated or simplified using the rules of arithmetic and algebra.
Here,
1. Simplify:
3(4x-2)+ 7X (2-1) + 4 (6+4)+(-8)
Multiplying inside the parentheses first:
12x - 6 + 7x + 4 + 40 - 8
Combining like terms:
19x + 30
Final answer: 19x + 30
2. Graph:
3 > X
This is a simple inequality in one variable (X). To graph it on a number line, we first draw a dot at 3 (since the inequality is strict), and then shade all values less than 3:
<=========o---
The open circle at 3 indicates that 3 is not included in the solution set.
3. Write the inequality:
X < 5
This is a simple inequality in one variable (X). The inequality sign is "less than," and the number on the right-hand side is 5. This inequality can be read as "X is less than 5" or "X is strictly less than 5."
4. Solve for x:
3x - 7 = 42
Adding 7 to both sides to isolate the variable:
3x = 49
Dividing both sides by 3 to solve for x:
x = 16.33 (rounded to two decimal places)
Final answer: x = 16.3
5. Find 32% of $542.50:
To find 32% of $542.50, we can use the formula:
percent * amount = part
where "percent" is the percentage expressed as a decimal, "amount" is the whole amount, and "part" is the result we're looking for.In this case, we have:
0.32 * $542.50 = part
Multiplying:
$173.60 = part
Final answer: $173.60

Solve for the short leg of the 30-60-90 triangle.
Answer:
2
Step-by-step explanation:
The basic 30-60-90 triangle ratio is:
Side opposite the 30° angle: x
Side opposite the 60° angle: x√3
Side opposite the 90° angle: 2x
Here, the side opposite the 90° angle is 4.
This means that 2x = 4 and, thus, x = 2.
Since b is the side opposite the 30° angle, b = x, so it is 2.

Suppose the current cost of gasoline is $2.93 per gallon. Find the current price index number, using the 1975 price of 56.7 cents as the reference value.
Answer:
Step-by-step explanation:
To find the current price index number using the 1975 price of 56.7 cents as the reference value, we can use the formula:
Price Index = (Current Price / Base Price) x 100
Where "Current Price" is the current cost of gasoline, and "Base Price" is the 1975 price of 56.7 cents.
Substituting the values given in the problem, we get:
Price Index = ($2.93 / $0.567) x 100
Price Index = 516.899
Therefore, the current price index number, using the 1975 price of 56.7 cents as the reference value, is 516.899.
