Which values are solutions to the inequality square root of x is less than 8? A. 55 B. 8 C. -8 D. 4 E. 65 F. -64
Dima020 [189]

9514 1404 393

Answer:

  A.  55

  B. 8

Step-by-step explanation:

We want ...

  √x < 8

  x < 8² . . . . . square both sides

  x < 64

In order for the inequality to make any sense, we must also have ...

  0 ≤ x

So, the solution space is ...

  0 ≤ x < 64

Only answer choices A (55) and B (8) are in that range.

\tt{ Hey \: there , \: Mr.Panda \: ! } ;)

♨\large{ \tt{ E \: X \: P \: L \: A \: N \: A \: T \: I\: O \: N}}:

⤻ Before solving the given question , you should know the answer of these questions :

✺How do you find the hypotenuse , perpendicular and base when the angle ( \theta \: , \alpha  \:  ,\beta ) is given ?

⇾ The longest side , which is the opposite side of right angle is the hypotenuse ( h ). There are two other sides , the opposite and the adjacent. The naming of these sides depends upon which angle is involved. The opposite is the side opposite the angle involved and it is called the perpendicular ( p ) . The adjacent us the side next to the angle involved ( buy not the hypotenuse ) and it is called the base ( b ).

☄ \large{ \tt{REMEMBER}} :

  • \bf{ \sin \theta =  \frac{opposite}{hypotenuse}  =  \frac{perpendicular}{hypotenuse}  }

  • \bf{ \cos\theta =  \frac{adjacent}{hypotenuse}  =  \frac{base}{hypotenuse}  }

  • \bf{ \tan \theta =  \frac{opposite}{adjacent}  =  \frac{perpendicular}{base}  }

In the above cases , \theta is taken as the angle of reference.

♪ Our Q/A part ends up here! Let's start solving the question :

❈ \large{ \tt{GIVEN}} :

  • Perpendicular ( p ) = ? , Hypotenuse ( h ) = 18 & base ( b ) = 16

✧ \large{ \tt{TO \: FIND} : }

  • Value of tan \theta

✎ \large{ \tt{SOLUTION}} :

Firstly , Finding the value of perpendicular ( p ) using Pythagoras theorem :

❃ \boxed{ \sf{ {h}^{2}  =  {p}^{2}  +  {b}^{2} }} [ Pythagoras theorem ]

\large{ ⇢ \sf{p}^{2}  +  {b}^{2}  =  {h}^{2} }

\large{⇢ \sf{ {p}^{2}  =  {h}^{2}  -  {b}^{2} }}

\large{ ⇢\sf{ {p}^{2}  =  {18}^{2}  -  {16}^{2} }}

\large{⇢ \sf{ {p}^{2}  = 324  - 256}}

\large{⇢ \sf{ {p}^{2}  = 68}}

\large{⇢ \sf{p =  \sqrt{68}}}

\large{ ⇢\sf{p =  \boxed{ \tt{2 \sqrt{17}}} }}

Okey, We found out the perpendicular i.e \tt{2 \sqrt{17}} . Now , We know :

❊ \large{ \sf{ \tan \theta} =  \frac{perpendicular}{base} }

\large {\tt{↬ \: tan \theta =  \frac{2 \sqrt{17} }{16}}}

\large{ \tt{ ↬ tan  \theta =  \frac{ \cancel{2} \:  \sqrt{17} }{ \cancel{16} \:  \: 8} }}

\large{ \tt{ ↬ \boxed{ \tt{tan \theta =  \frac{ \sqrt{17} }{8}}}}}

⟿ \boxed{ \boxed{ \tt{OUR\: FINAL \: ANSWER : \boxed{ \underline{ \bf{ \frac{ \sqrt{17} }{8}}}}}}}

۵ Yay! We're done!

♕ \large\tt{RULE \: OF \:SUCCESS }:

  • Never lose hope & keep on working ! ✔

ツ Hope I helped!

☃ Have a wonderful day / evening! ☼
