Answer:

OPTION B

Step-by-step explanation:

It represents the product of two irrational numbers and is equivalent to an irrational number.

Given: $ \sqrt{3} \times \sqrt{2} $.

These two numbers are irrational numbers.

Irrational numbers are those whose decimal representations either do not form a pattern or are non - terminating.

$ \sqrt{2} = 1.414 \hdots $

$ \sqrt{3} = 1.732\hdots $

They are irrational numbers.

Product of $ \sqrt{3} \times \sqrt{2} $ = $ \sqrt{6} $.

This is again an irrational number. So, OPTION B is the answer.

Answer:

<h2>Option B is the right answer.</h2>

Step-by-step explanation:

\sqrt{3} , \sqrt{2} are two irrational numbers, that is, they can not be shown as the fraction of two integers.

\sqrt{3} \times\sqrt{2} = \sqrt{6}

\sqrt{6} is also a irrational number, since it also can not be represented as the fraction of integers.

Hence, the given expression represent the product of two irrational number and is equivalent to an irrational number.

Solve x^2+11X&lt;-8 Urgent please help!!!!!
Tamiku [17]
Add 121/4 to each side:
x²+11x+121/4 < 121/4-8
x²+11x+121/4 < 89/4
(x+11/2)² < √89/2 ⇒ -√89/2 < x+11/2 < √89/2
-11/2-√89/2 < x < -11/2+√89/2

Pat needs to determine the height of a tree before cutting it down to be sure that it will not fall on a nearby fence. The angle
dem82 [27]

Answer:

229.23 feet.

Step-by-step explanation:

The pictorial representation of the problem is attached herewith.

Our goal is to determine the height, h of the tree in the right triangle given.

In Triangle BOH

Tan 60^0=\dfrac{h}{x}\\h=xTan 60^0

Similarly, In Triangle BOL

Tan 50^0=\dfrac{h}{x+60}\\h=(x+60)Tan 50^0

Equating the Value of h

xTan 60^0=(x+60)Tan 50^0\\xTan 60^0=xTan 50^0+60Tan 50^0\\xTan 60^0-xTan 50^0=60Tan 50^0\\x(Tan 60^0-Tan 50^0)=60Tan 50^0\\x=\dfrac{60Tan 50^0}{Tan 60^0-Tan 50^0} ft

Since we have found the value of x, we can now determine the height, h of the tree.

h=\left(\dfrac{60Tan 50^0}{Tan 60^0-Tan 50^0}\right)\cdotTan 60^0\\h=229.23 feet

The height of the tree is 229.23 feet.
