Just need to put zero instead of y and solve the equation for find the value of x :
0 = 2 Cot ( x/4 )
Cot ( x/4 ) = 0
Cot ( x/4 ) = Cot ( π / 2 )
x / 4 = π / 2
x = 4 × π / 2
x = 2π
Thus the correct option is C .

Step-by-step explanation:
Notice that the dividend has tree terms with , , c
Now, to divided our dividend by the monomial (single term) , the easiest thing to do is divide each term of the dividend by the monomial:
÷ =
After performing the division we get that now and
We can conclude that the correct answer is a = 2y and b = –3
Factor to write an equivalent expression.(What is the Greatest Common Factor?).
−9x+15y
Answer:
GCF is 3
Step-by-step explanation:
Given the expression -9x + 15y
First, we need to find ther individual factors
-9x = -3 *3 * x
15y = 3 * 5 * y
Since 3 is common to both factors
−9x+15y = 3(-3x+5y)
Hence the GCF is 3
what does sides of equal length mean
Answer:
equilateral
Step-by-step explanation:
A shape is equilateral if all the sides are the same length. In geometry class, people learn about many shapes, such as triangles and squares. A square is equilateral, because all of its sides are the same length. ... The word equal should help you remember what equilateral means.
Answer:
An isosceles triangle has 2 sides of equal length . The dashes on the lines show they are equal in length. The angles at the base of the equal sides are equal.An equailateral triangle has 3 sides of equal length.

What is the volume of a sphere with a radius of 31.6 cm, rounded to the nearest tenth of a cubic centimeter?
Answer:
The answer is 132175.2 cubic centimeters or 1.3 times 10^5 cubic centimeters in scientific notation.
Step-by-step explanation:
To solve for the volume of the sphere, start by using the formula for the volume of a sphere, which is V= [tex]\frac{4}{3}[/tex][tex]\pi[/tex][tex]r^{3}[/tex].
Next, plug in the information given from the question into the formula. The formula will then look like V= [tex]\frac{4}{3}[/tex]([tex]\pi[/tex])([tex]31.6^{3}[/tex]).
Then, simplify and solve for the answer. The final answer is 132175.2 cubic centimeters or 1.3 times 10^5 cubic centimeters in scientific notation.

Helpppppp!!!!!!!!!!!!!
============================================================
Explanation:
As the diagram shows, we have a triangular face with a base of b = 18 and height of h = 13. The area of this triangular face is:
A = 0.5*b*h
A = 0.5*18*13
A = 117 square cm or cm^2
This represents the area of one face, but there are 4 identical copies of this triangular face assuming this tetrahedron is a regular polyhedron. So we have a total surface area of 4*117 = 468 cm^2 which points us to choice B

Assume that a sample is used to estimate a population proportion p. Find the 99.9% confidence interval for a sample of size 247 with 85% successes. Enter your answer as a tri-linear inequality using decimals (not percents) accurate to three decimal places
Answer: [tex]0.791\leq p\leq0.909[/tex]
Step-by-step explanation:
The confidence interval for the population proportion is given by:-
[tex]\hat{p}\pm z^*\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}[/tex], where [tex]\hat{p}[/tex]= sample proportion, n =sample space , z* = critical z-value.
As per given, we have
[tex]n = 247[/tex]
[tex]\hat{p}=0.85[/tex]
Critical value for 99.9% confidence = 2.576
The required confidence interval will be:
[tex]0.85-2.576\sqrt{\frac{0.85\times0.15}{247}}\leq p\leq 0.85+2.576\sqrt{\frac{0.85\times0.15}{247}}\\\\\Rightarrow\ 0.85-(0.058526)\leq p \leq0.85+(0.058526)\\\\\Rightarrow\ 0.791474\leq p\leq0.908526\approx0.791\leq p\leq0.909[/tex]
The required confidence interval: [tex]0.791\leq p\leq0.909[/tex]

A random sample of 18 adults, chosen from the 1500 adults in the town, took a survey asking their opinion on a recent property tax change. 25% of those who responded said they were in favor of the change. The company running the survey wants to construct a confidence interval estimating the proportion of all adults in the town who support the change. Which of the conditions for inference have been satisfied?
Answer: Random condition
10% condition
Step-by-step explanation:
The conditions for inference that have been satisfied will be:
• Random condition: This has been satisfied since a random sample of 18 adults were taken from 1500 adults.
• 10% condition: Since 25% of those who responded said they were in favor of the change, then the 10% condition is satisfied.
