Answer:

Figure 3 shows the shaded area for (C\cup B)\cap A'.

Step-by-step explanation:

It is given that A, B and C are three different sets. U is the universal set.

We need to find the shaded area for (C\cup B)\cap A'.

Here,

\cup = Union

\cap = Intersection

Now,

(C\cup B) means either C or B.              .... (1)

A'=U-A means all part U except A.           .... (2)

The shaded region for both conditions is shown below.

(C\cup B)\cap A' is intersection of (1) and (2).

So, the final shaded reason is shown in figure 3.

Answer:

In mathematics, the intersection A ∩ B of two sets A and B is the set that contains all elements of A that also belong to B (or equivalently, all elements of B that also belong to A), but no other elements. For explanation of the symbols used in this article, refer to the table of mathematical symbols.

We just saw how to join two sets using "Union" (and the symbol ∪). There is also "Intersection" which means "has to be in both". Think "where do they overlap?". The Intersection symbol is an upside down "U" like this: ∩

<h2>Please mark me as brainlyist</h2>

it is this because it says to shade b and c so i did that but also it says to shade u and it says u is n and n is a so you shade b c and a

Answer:

25.047 or roughly 25.

Step-by-step explanation:

I solved it wrong the first time then i double check with wolframalpha and got the correct number.

We know that the area of the tile is 18 \sqrt{3} and it makes a triangle, we also know the base and height. In this case the base is 2\sqrt{3}^{x/12} and the height is also given which is \sqrt{3}^{\frac{x}{6} }.

Area of triangle = \frac{bh}{2},

substituting we will end up with  18 \sqrt{3}  =( 2\sqrt{3}^{x/12}  *  \sqrt{3}^{\frac{x}{6} }) / 2

Here is the tricky part \sqrt{x} = x^{\frac{1}{2} }, i totally forgot about that lol.

Simplifying: we will get  18 \sqrt{3} = 3^{\frac{x}{8} }

Now, in order to find the x, we will need to take the log of both sides.

log18\sqrt{3}  = \frac{x}{8} log3

Solving for x we end up getting:

8\frac{log18\sqrt{3} }{log3} = x

where x = 25.047.

To be honest I deserve a nobel prize not a brainliest lol.

Good question bro, take it easy.

Find the value of y, given that m_ KLM = 137º.
Musya8 [376]

Answer:

y ≈ 5.63

Step-by-step explanation:

m∠KLN and m∠NLM have to add up to m∠KLM

m∠KLN = 47°

m∠NLM = 16y°

m∠KLM = 137°

47 + 16y = 137

16y = 90

y = 45/8

y = 5.625

y ≈ 5.63
