Let X and Y be the following sets:

MA_775_DIABLO [31]

Given:

Let X and Y be two sets.

The two sets are given by $X=\{5,10,15\}$ and $Y=\{3,6,9,12,15\}$

We need to determine the value of the set $X \cup Y$

Value of the set $X \cup Y$ :

The value of the set $X \cup Y$ is the set that contains all the elements that are at least in one of the two sets.

Hence, the union of the set $X \cup Y$ is given by

$X \cup Y=\{5,10,15\} \cup \{3,6,9,12,15\}$

$X \cup Y=\{5,10,15,3,6,9,12\}$

Arranging in ascending order, we get;

$X \cup Y=\{3,5,6,9,10,12,15\}$

Thus, the union of the sets X and Y is $X \cup Y=\{3,5,6,9,10,12,15\}$

Please help me on this

Gre4nikov [31]

Answer: option a.

Step-by-step explanation:

Given the expression $\sqrt{8^{17}}$ , you need to remember:

The Product of powers property:

$a^m*a^n=a^{(m+n)}$

The Power of a power property:

$(a^m)^n=a^{mn}$

And:

$\sqrt[n]{a^n}=a$

Therefore, as the index of the radical is 2, you can rewrite $8^{17}$ as:

$8^{17}=8^{16}*8$

Rewrite this and simplify. Then:

$=\sqrt{8^{17}}$

$=\sqrt{8^{16}*8}=\sqrt{8^{16}}\sqrt{8}=\sqrt{(8^{8})^2}\sqrt{8}=8^8\sqrt{8}$

This matches with the option a.

The triangles are similar. What is the value of x?

Mashcka [7]

Answer:

x=4

Step-by-step explanation:

First of all, the sides of the smaller triangle are multiplied by 5 to make it bigger. So, multiply 4 by 5 which gives you 20. So, 20= 3x+8.

Now that we have our equation, we need to isolate the variable.

Subtract 8 from both sides.

20= 3x+8

- 8 -8

Divide both sides by 3.

12= 3x

3 3

x= 4
