Answer:

g = 12

Step-by-step explanation:

You recognize that 144 is 12², so you check to see if the x-coefficient is 2·12. It is. The quadratic is a square:

(g -12)² = 0

The only solution is the one that makes the squared term equal to zero:

g -12 = 0

g = 12

_____

The square of a binomial is ...

(a +b)² = a² +2ab +b²

Here, we have a=x, b=-12.

What is the approximate volume of the sphere? Use 3.14 to approximate pi and round your answer to the nearest hundredth if neces

OLga [1]

Answer: $523.33\ mm^3$

Step-by-step explanation:

We know that the volume of sphere is given by :-

$\text{Volume}=\frac{4}{3}\pi r^3$ , where r is the radius of sphere.

Given: The length of the dotted line extending from middle point of sphere to edge must be the radius of the sphere.

Now, radius of the sphere = 5 mm

The volume of the given sphere will be :-

$\text{Volume}=\frac{4}{3}\pi (5)^3\\\\\Rightarrow\ \text{Volume}=\frac{4}{3}(3.14)(125)\\\\\Rightarrow\ \text{Volume}=523.3333\approx523.33\ mm^3$

Quadrilateral ABCD?<br>

Mashutka [201]

The given quadrilateral is a kite.

Given: Point A (2, 4), B (-2, -5), C (7, -1) and D (7, 4)

Firstly, we find the distance between AD and DC

AD = $\sqrt{(7 - 2)^{2} + (4 - 4)^{2} }$

⇒ AD = $\sqrt{5^{2} }$

⇒ AD = 5

DC = $\sqrt{(7 - 7)^{2} + (4 - (-1))^{2} }$

⇒ DC = $\sqrt{5^{2} }$

⇒ DC = 5

Hence, AD = DC = 5

Now, find the distance between AB and BC

AB = $\sqrt{(-2 - 2)^{2} + (-5 - 4)^{2} }$

⇒ AB = $\sqrt{(-4)^{2} + (-9)^{2} }$

⇒ AB = $\sqrt{16 + 81}$

⇒ AB = $\sqrt{97}$

BC = $\sqrt{(7 - (-2))^{2} + (-1 - (-5))^{2} }$

⇒ BC = $\sqrt{9^{2} + 4^{2} }$

⇒ BC = $\sqrt{81 + 16}$

⇒ BC = $\sqrt{97}$

Hence, AB = BC = √97

In the given quadrilateral, the two pair is of equal length and these sides are adjacent to each other.

Hence, it follows the property of kite.
