Answer» Solve the given equation :- $\sf Q) \: 3x + 8 = 5x + 2$ Putting the CONSTANTS and the variables on different sides by transposing, $\sf\Rightarrow3x - 5x = 2 - 8$ On simplifying, $\sf \Rightarrow- 2x = - 6$ Transposing -2 from LHS to RHS, changing it's SIGN, $\sf \Rightarrow x = \dfrac{ - 6}{ - 2}$ Dividing -6 by -2, $\sf \Rightarrow x = 3.$ Therefore, the value of x = 3. ----------------------------------------------------------- Verification :- To check our answer, let's PUT 3 (The value of x) in the place of x and see whether LHS = RHS. Let's proceed! LHS $\sf\Rightarrow3 \times 3 + 8$ Applying the BODMAS rule and multiplying 3 by 3 first, $\sf\Rightarrow9 + 8$ On adding the NUMBERS, $\sf\Rightarrow17.$ RHS $\sf\Rightarrow5 \times 3 + 2$ Applying the BODMAS rule and multiplying 5 by 3 first, $\sf\Rightarrow15 + 2$ On adding the numbers, $\sf\Rightarrow17.$ Since LHS = RHS, Hence verified!

3.

3x+8=5x+2Solve the given equation.

Answer»

Solve the given equation :-

$\sf Q) \: 3x + 8 = 5x + 2$

Putting the CONSTANTS and the variables on different sides by transposing,

$\sf\Rightarrow3x - 5x = 2 - 8$

On simplifying,

$\sf \Rightarrow- 2x = - 6$

Transposing -2 from LHS to RHS, changing it's SIGN,

$\sf \Rightarrow x = \dfrac{ - 6}{ - 2}$

Dividing -6 by -2,

$\sf \Rightarrow x = 3.$

Therefore, the value of x = 3.

-----------------------------------------------------------

Verification :-

To check our answer, let's PUT 3 (The value of x) in the place of x and see whether LHS = RHS.

Let's proceed!

LHS

$\sf\Rightarrow3 \times 3 + 8$

Applying the BODMAS rule and multiplying 3 by 3 first,

$\sf\Rightarrow9 + 8$

On adding the NUMBERS,

$\sf\Rightarrow17.$

RHS

$\sf\Rightarrow5 \times 3 + 2$

Applying the BODMAS rule and multiplying 5 by 3 first,

$\sf\Rightarrow15 + 2$

On adding the numbers,

$\sf\Rightarrow17.$

Since LHS = RHS,

Hence verified!

8.	Show that tan 3x tan 2x tan x = tan 3x – tan 2x – tan x.
Answer» To Prove tan 3X tan 2x tan X = tan 3x – tan 2 x – tan x. Solution: To prove: tan 3x tan 2x tan x = tan 3x – tan 2 x – tan x We know that 3x can be written as 2x+x Hence, tan 3x = tan (2x+x) By using the trigonometric identity, the above expression is written as:Tan 3x = (tan 2x + tanx)/(1-tan 2x tanx) Now, cross MULTIPLY above expression, we get Tan 3x – tan 3x tan 2x tan x = tan 2x + tan x Simplify the above equation, we get tan 3x tan 2x tan x = tan 3x – tan 2x – tan x Hence, tan 3x tan 2x tan x = tan 3x – tan 2x – tan x is proved.

8.

Show that tan 3x tan 2x tan x = tan 3x – tan 2x – tan x.

Answer»

To Prove

tan 3X tan 2x tan X = tan 3x – tan 2 x – tan x.

Solution:

To prove: tan 3x tan 2x tan x = tan 3x – tan 2 x – tan x

We know that 3x can be written as 2x+x

Hence, tan 3x = tan (2x+x)

By using the trigonometric identity, the above expression is written as:Tan 3x = (tan 2x + tanx)/(1-tan 2x tanx)

Now, cross MULTIPLY above expression, we get

Tan 3x – tan 3x tan 2x tan x = tan 2x + tan x

Simplify the above equation, we get

tan 3x tan 2x tan x = tan 3x – tan 2x – tan x

Hence, tan 3x tan 2x tan x = tan 3x – tan 2x – tan x is proved.

18.

Show that 2 sin2β + 4 cos (α + β) sin α sin β + cos 2 (α + β) = cos 2α.

Answer»

LHS = 2 SIN2 β + 4 cos (α + β) sin α sin β + cos 2(α + β)

= 2 sin2 β + 4 (cos α cos β – sin α sin β) sin α sin β + (cos 2α cos 2β – sin 2α sin 2β)

= 2 sin2 β + 4 sin α cos α sin β cos β – 4 sin2 α sin2 β + cos 2α cos 2β – sin 2α sin 2β

= 2 sin2 β + sin 2α sin 2β – 4 sin2 α sin2 β + cos 2α cos 2β – sin2α sin2β

= (1 – cos 2β) – (2 sin2 α) (2 sin2 β) + cos 2α cos 2β

= (1 – cos 2β) – (1 – cos 2α) (1 – cos 2β) + cos 2α cos 2β

Answer» Answer: Step-by-step explanation: Given: Distance between the two MEN = 800 m , v = 340 m/s , distance between the two men from the hillock is same. Solution: The time taken (t) for the direct sound to be HEARD by the other man = d / v = 800/340 seconds t = 40/17 seconds Now, since the other man hears the echo 3s after the direct sound is heard , Therefore; total time taken(T) to hear the echo = ( t + 3 ) s = 40/17 + 3 T = 92/17 seconds Now; T = 92/17 s , d (dist. of the two men from the hillock) = ? , v = 340m/s Therefore; distance of the two men from the hillock( = distance of one man from the hillock) = vT/2 = (340 × 92/17 × 1/2) m = 920m (Ans) MARK me as the brainiest please

Two men 960m apart stand at the same distance from a vertical hillock. One of them fires the shot and other hears the echo 2 sec after hearing the direct sound. find the distance of the men from the hillock assuming the velocity of sound as 320m/s.

Answer»

Answer:

Step-by-step explanation:

Given: Distance between the two MEN = 800 m , v = 340 m/s , distance between the two men from the hillock is same.

Solution:

The time taken (t) for the direct sound to be HEARD by the other man = d / v

= 800/340 seconds

t = 40/17 seconds

Now, since the other man hears the echo 3s after the direct sound is heard ,

Therefore; total time taken(T) to hear the echo = ( t + 3 ) s

= 40/17 + 3

T = 92/17 seconds

Now;

T = 92/17 s , d (dist. of the two men from the hillock) = ? , v = 340m/s

Therefore;

distance of the two men from the hillock( = distance of one man from the hillock) = vT/2

= (340 × 92/17 × 1/2) m

= 920m (Ans)

36.	A wheel makes 360 revolutions in one minute. Through how many radians does it turn in one second?
Answer» ANSWER: $Number of revolutions made by the wheel in 1 second=36060=6 revolutions. As we know in one complete revolution, the wheel turns at an angle of 2π radian. Hence, in 6 complete revolutions, it will turn an angle of 6×2π radian, i.e. 12π radian. Thus, in one second, the wheel turns at an angle of 12π radian.$
