First of all, what is an integer?

Integers are numbers such as -7, -4, 0, 5, 16... etc...

This means that even integers are numbers such as:

-4, -2, 0, 2, 4, 6, 8, 10... etc...

Which means that:

AUB={..., -4, -2, 0, 2, 4, 5, 6, 7, 8, 10, 12, 14, ...}

This is because:

The union "<span>U</span>" of two sets must contain all the numbers from both sets, providing they aren't duplicated.

Hello!

To solve this we use the equation sin60 = (s/2) / (d/2)

s is a side of the triangle
d is the diameter

sin60 = s/d

\sqrt{3/4} =s/d

d=s/ \sqrt{3/4}

d = s \sqrt{4/3}

d = 2s/ \sqrt{3}

put 6 in for s

d=12/ \sqrt{3}

d =  \sqrt{48}

d = 6.9

The answer is C) 6.9

Hope this helps!

Graphing Form for Linear Equations in 2 variables.
NeX [460]
X-intercept: y = 0
y-intercept: x = 0

3x + 4y = 0

x-intercept: subtitute y = 0
3x + 4 · 0 = 0
3x = 0
x = 0 → (0; 0)

y-intercept: subtitute x = 0
3 · 0 + 4y = 0
4y = 0
y = 0 → (0; 0)
