If A = {x | x is an even integer}, B = {5, 6, 7, 8}, list the elements of the set A U B

ahrayia [7]

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.

Select the polynomial that is a perfect square trinomial. 36x2 − 4x 16 16x2 − 8x 36 25x2 9x 4 4x2 20x 25.

Naya [18.7K]

The polynomial a,b,c,are not perfect square polynomial and the polynomial d is perfect square polynomial.

The given polynomial is

$a) 36x^2-4x+16$

What is the form of perfect square polynomial?

$(ax+b)^2$

we solve this method by using perfect square method

add and subtract 1/9

$36x^2-4x+16+\frac{1}{9}-\frac{1}{9}$

factor 36

$\frac{143}{9}+36(x^2-\frac{x}{9}+\frac{1}{324} )$

Now complete the square

$\frac{143}{9}+36(x^2-\frac{1}{18})^2$

Therefore this is not perfect square trinomial.

Similarly for

$b) 16x^2-8x+36$

Complete square is,

$16(x-\frac{1}{4})^2+35$

This polynomial is also not perfect square trinomial.

$c) 25x^2+9x+4\\$

complete square is,

$25(x+\frac{9}{50})^2+\frac{319}{100}$

This polynomial is not perfect square trinomial.

$d)4x^2+20x+25\\$

complete square is,

$(2x+5)^2$

This polynomial is perfect square trinomial.

Therefore,

The polynomial a,b,c,are not perfect square polynomial and the polynomial d is perfect square polynomial.

The center of a circle is at (0, 0), and the radius of the circle is 3(sqrt)2

Assoli18 [71]

Answer:

B

Step-by-step explanation:

The equation of a circle is denoted by: $(x-h)^2+(y-k)^2=r^2$ , where (h, k) is the center and r is the radius.

Here, we see that the center is (0, 0), so h = 0 and k = 0. Also, the radius is $3\sqrt{2}$ , so r = $3\sqrt{2}$ and $r^2=(3\sqrt{2})^2=9*2=18$ .

Then we can write our equation:

$(x-0)^2+(y-0)^2=18$

$x^2+y^2=18$

The answer is B.

Hope this helps!
