A circle has a circumference of 6. It has a lenth of 1/3. What is the central angle of the arc?

Can you please answer my homework, its about sets.

Katyanochek1 [597]

The value of the set (A∪C)'∩B is {9 , 12} .

A subfield of mathematical logic called set theory examines sets, which are essentially collections of objects.

Set theory is a discipline of mathematics that largely addresses problems that are pertinent to mathematics as a whole, despite the fact that any kind of object can be constructed into a set.
Set theory is founded on a simple binary relationship between an object o and a set A.
It is written as o A if o is a part (or member) of A. Members of a set are enumerated with commas to denote separation when describing them, or a property of those parts is enclosed in braces.
Sets can be associated by the membership relation since they are objects.

The given sets are:

U ={1,2,3,4,5,6,7,8,9,10,11,12,13}

A = {3,7,11,13}

B = {3,6,9,12,13}

C = {2,3,5,6,7,8}

Now B' = {1,2,4,5,7,8,10,11}

b) B'∩C = {2,5,7,8,}

c) A∪C = {2,3,5,6,7,8,11,13}

(A∪C)' = {1,4,9,10,12}

(A∪C)'∩B = {9 , 12}

Hence the value of the set (A∪C)'∩B is {9 , 12} .

Osvaldo’s teacher asked him to write an equivalent equation for length, l, in terms of perimeter, p, and width, w. He wrote:

Andrej [43]

Answer:

step 2

Step-by-step explanation:

Given

p = 2l + 2w ( subtract 2w from both sides )

p - 2w = 2l ← correct step 1

Now, divide both sides by the multiplier 2

$\frac{p-2w}{2}$ = l

Solve the given equation. (Enter your answers as a comma-separated list. Let k be any integer. Round terms to two decimal places

Ghella [55]

Answer:

That is the solutions are:

$\frac{\pi}{3}+2\pi \cdot k$ , $\frac{5\pi}{3}+2\pi \cdot k$

Step-by-step explanation:

The period of $\cos(x)$ or $\sin(x)$ is $2\pi$ .

Let's look at the first rotation to see when $\cos(\theta)=\frac{1}{2}$ happens.

This happens at $\frac{\pi}{3}$ and also at $\frac{5\pi}{3}$ . (Notice I just looked at the x-coordinates because that is what cosine is. Sine is the y-coordinate.)
