If two sets are same let a and bthen we can say a= b
according to definition of intersection it is function that contains common enements from both setsas a=b so all elemnts are commonso a= a n bor b = a n b
in union the function has all elements of both sets and in set no element repeats so 
a u b = aor a u b = b
as a u b  = a or b and a n b = a or b so we can conclude here that
a u b = a n b as a = b // defined above

2. The cone has a radius of 30 mm and slant height of 34 mm. What is the height h for this cone?​
Flura [38]

Answer:

h = 16

Step-by-step explanation:

By applying the Pythagorean Theorem, the slant height is given by the formula:

\sqrt{r^2+h^2}

34 = \sqrt{30^2 + h^2}

34^2 = 30^2 + h^2

1156 = 900 + h^2

256 = h^2

h = \sqrt{256}

h = 16

I am once again asking the mathematical geniuses of the world to solve a rather simple problem that my small brain can't compreh
Nitella [24]
Ooh ok these are fun. So these triangles are similar, meaning they are in proportion. In triangle LMN, line LM is 21. To find the corresponding line on the other triangle, we need to find the corresponding letters in the names. Because L and M are the first two letters, we need to use the first two letter s in the other name, so FG. Line FG is 9, so our first proportion is 9/21

The sum of two numbers is 30 and their difference is 6
Studentka2010 [4]

I'm going to assume that you are trying to find the two numbers. Based on the information in the problem, we can create the following equations (where a and b are the two numbers):

a + b = 30

a - b = 6


We have a systems of equations. In this case, it would be easier to use elimination by adding vertically. This produces the result:

2a = 36

a = 18


To find b, substitute the value for a into one of the earlier equations:

18 + b = 30

b = 12


The two numbers are 12 and 18.
