which value is a solution for the equation cot x/2=1?
The solution for the equation is [tex]x=\frac{\pi }{2} +2\pi n[/tex] ,for any integer n.
What is an equation?An equation is the statement that asserts th equality of the two expressions with 'equal to' (=) sign.
cot [tex]\frac{x}{2} =1[/tex],
Taking inverse on both sides we get,
[tex]\frac{x}{2}[/tex] = [tex]cot^{-1} (1)[/tex]⇒[tex]\frac{x}{2}=\frac{\pi}{4}[/tex]
⇒[tex]x=\frac{\pi }{2}[/tex].
cot is positive in first and third quadrant. To find the second solution add π to it.
[tex]\frac{x}{2} =\pi +\frac{\pi }{2}[/tex]
[tex]x=\frac{5\pi }{2}[/tex]
to find period for cot([tex]\frac{x}{2}[/tex])
The periodic function can be calculated by [tex]\frac{\pi }{|b|}[/tex], replace b with [tex]\frac{1}{2}[/tex]
we get [tex]2\pi[/tex]. we get period for cot([tex]\frac{x}{2}[/tex]) is [tex]2\pi[/tex] so values will repeat every
radians in both directions.
[tex]x=\frac{\pi }{2} +2\pi n, \frac{5\pi }{2} +2\pi n,[/tex] for any integer n.
consolidating we get,
[tex]x=\frac{\pi }{2} +2\pi n[/tex], for any integer.
Hence, the solution for the equation cot [tex]\frac{x}{2}[/tex]= 1 is [tex]x=\frac{\pi }{2} +2\pi n[/tex]

find the intersection of the set of odd integers between 0 and 20 and the set of multiples of 5 between 0 and 35 inclusive.
The intersection of the set of integers and multiples of 5 will be (5,15).
What exactly are integers?
In mathematics, integers are the collection of positive and negative numbers. Integers, like whole numbers, do not include the fractional element. Thus, integers are numbers that can be positive, negative, or zero, but not fractions. On integers, we can do all arithmetic operations such as addition, subtraction, multiplication, and division. Integers include numbers such as 1, 2, 5, 8, -9, -12, and so on. "Z" is the symbol for integers.
Now,
Odd Integers between 0 and 20=1,3,5,7,9,11,13,15,17,19
Multiples of 5 between 0 and 35=5,10,15,20,25,30,35
Then the common integers are=5,15
Hence,
The intersection of the set of integers multiples of 5 will be (5,15).

What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
The total amount of snow that falls in three days equals the sum of the amount of snow that falls each day, then
s1 + s2 + s3 = Ts
Here s1 is the snow that fell on day 1, s2 on day 2, s3 on day 3 and Ts is the total amount of snow that fell over the three days.
We need to calculate the amount of snow that fell on the first two days by multiplying the total snow by the given fractions, like this:

100 POINTS HELP How would a delivery on products listed as a $5000 Unearned Revenue credit be recorded on an accounting worksheet?
A. a $5000 Adjustment debit
B. a $5000 Trial Balance debit
C. an increase in T.B. revenue
D. a $5000 Adjusted T.B. credit
Answer: A
Step-by-step explanation:
If there is a $5000 Unearned Revenue credit on the accounting worksheet, it means that the company has received payment for products or services that have not yet been delivered. Therefore, when the delivery is made, an adjusting entry is needed to reflect the change in the company's financial statements.
The adjusting entry would be a debit to the Unearned Revenue account for $5000 and a credit to the Revenue account for $5000, reflecting the delivery of the products and the recognition of revenue. The entry would be recorded in the Adjustment column of the worksheet.
Therefore, the correct answer is option A, a $5000 Adjustment debit.
Answer:
A. a $5000 Adjustment debit
Step-by-step explanation:
The delivery of products listed as a $5000 Unearned Revenue credit would be recorded on an accounting worksheet with a $5000 Adjustment debit.
Unearned revenue is a liability account that represents payments received from customers for goods or services that have not yet been provided. When the delivery is made and the products are provided, the unearned revenue is "earned" and the revenue is recognized in the accounting records.
To record the delivery and recognize the revenue earned, the company would make an adjusting entry to decrease the unearned revenue account and increase the revenue account. Since the unearned revenue account has a credit balance, the adjusting entry would require a debit to reduce the balance. This would result in a $5000 Adjustment debit to Unearned Revenue and a $5000 Adjustment credit to Revenue.

What Is The Difference Between Apparent Capacity And Actual Capacity Of A Glass Vessel? IN SURFACE AREA AND VOLUME!!?
Hence, the cylinder's content determines the apparent volume of the glassware, and also the difference between the cylinder as well as spherical volumes determines the glass's true capacity.
What can be termed Capacity?Capacity can be defined as the amount which can be held by any kind of vessel. This can depend upon their depth as well as their size.
Actual capacity is the volume of liquid that a glass vessel can contain while it is only partially filled, as opposed to capacity, which refers to the volume of liquid when the glass vessel is fully filled to the brim.
The distinction between both apparent capacity versus Actual capacity in parameters of surface area, as well as volume, is that the former refers to the entire surface area proportional volume of the vessel, whilst the latter refers to the surface area but instead the volume of the liquid that could also fit.

The most precise classification of BCDE is a square.
What are Quadrilaterals?Quadrilaterals are four sided polygons which also have four vertices and four angles.
Sum of all the interior angles of a quadrilateral is 360 degrees.
We have to find the length of adjacent sides of the quadrilateral BCDE.
If they are equal, then the quadrilateral is either square or rhombus.
If they are not equal, then they are either rectangle or parallelogram.
B(-1, -1), C(6, -2), D(5, -9), and E(-2, -8)
BC = [tex]\sqrt{(6--1)^2+(-2--1)^2}[/tex] = √50
CD = [tex]\sqrt{(5-6)^2+(-9--2)^2}[/tex] = √50
Adjacent sides are equal. So it is either square or rhombus.
If it is rhombus, length of diagonals BD and CE are not equal.
If it is square, length of diagonals BD and CE are equal.
BD = [tex]\sqrt{(5--1)^2+(-9--1)^2}[/tex] = √100 = 10
CE = [tex]\sqrt{(-2-6)^2+(-8--2)^2}[/tex] = √100 = 10
Length of diagonals are same. So it is a square.

A numbler of workers must weed a large Wheat Field. The number of daisies iwill it takes them variesation inversely with the number of workers. If it takes 6 days for 10 workers to weed the field, how lowly manely days would the weadingg take if there were twelve workers?
Answer: Let x be the number of days it takes for y workers to weed the field. Then, we know that x and y are inversely proportional, meaning that x * y = k, where k is a constant.
Since it takes 6 days for 10 workers to weed the field, we have:
6 * 10 = k
So, k = 60.
Now, to find the number of days it would take if there were 12 workers, we can plug in y = 12 and solve for x:
x * 12 = 60
x = 60/12
x = 5
Therefore, it would take 5 days for 12 workers to weed the field.

Mean = 14, SE = 2
Mean = 8, SE = 2
Mean = 15, SE = 6
Mean = 20, SE = 1
Of the given four estimators, the one that shows the most bias is Mean = 20, SE = 1. Hence, Mean = 20, SE = 1 is the accurate choice.
The estimator with the highest value (Mean = 20) compared to the population parameter (15) is the most biased. The lower the standard error (SE = 1), the more confident the estimate, but if the estimate is far from the population parameter, it is considered biased.
In this case, the Mean = 20 estimator is the most biased because it has the greatest difference from the population parameter and the lowest standard error, indicating a high level of confidence in the estimate despite it being significantly different from the actual population parameter.
