6.	If 0 < θ < π/8
Answer» Step-by-step explanation: GIVEN:- 0 < θ < π/8 To PROVE:- $\rm\sqrt{2 + \sqrt{2 + \sqrt{2 + 2cos4 \theta} } } = 2cos \theta/2$ Formula Used:- 1 + cosθ = 2 cos² θ/2 Proof:- $\rm <klux>LHS</klux> = \sqrt{2 + \sqrt{2 + \sqrt{2 + 2cos4 \theta} } }$ $\rm= \sqrt{2 + \sqrt{2 + \sqrt{2 (1+ cos4 \theta)} } }$ $\rm= \sqrt{2 + \sqrt{2 + \sqrt{2 (2 cos^{2} 2\theta)} } }$ $\rm= \sqrt{2 + \sqrt{2 + \sqrt{4 cos^{2} 2\theta} } }$ $\rm= \sqrt{2 + \sqrt{2 + 2cos2 \theta} }$ $\rm= \sqrt{2 + \sqrt{2 (1 + cos2 \theta)} }$ $\rm= \sqrt{2 + \sqrt{2 (2cos ^{2} \theta)} }$ $\rm= \sqrt{2 + \sqrt{4cos ^{2} \theta} }$ $\rm= \sqrt{2 + 2cos \theta }$ $\rm= \sqrt{2 (1 + cos \theta) }$ $\rm= \sqrt{2 (2cos^{2} ( \theta/2) }$ $\rm= \sqrt{4cos^{2} ( \theta/2) }$ $\rm= 2cos( \theta/2)$ LHS = RHS Hence Proved

6.

If 0 < θ < π/8

Answer»

Step-by-step explanation:

To PROVE:-

$\rm\sqrt{2 + \sqrt{2 + \sqrt{2 + 2cos4 \theta} } } = 2cos \theta/2$

Formula Used:-

1 + cosθ = 2 cos² θ/2

Proof:-

$\rm <klux>LHS</klux> = \sqrt{2 + \sqrt{2 + \sqrt{2 + 2cos4 \theta} } }$

$\rm= \sqrt{2 + \sqrt{2 + \sqrt{2 (1+ cos4 \theta)} } }$

$\rm= \sqrt{2 + \sqrt{2 + \sqrt{2 (2 cos^{2} 2\theta)} } }$

$\rm= \sqrt{2 + \sqrt{2 + \sqrt{4 cos^{2} 2\theta} } }$

$\rm= \sqrt{2 + \sqrt{2 + 2cos2 \theta} }$

$\rm= \sqrt{2 + \sqrt{2 (1 + cos2 \theta)} }$

$\rm= \sqrt{2 + \sqrt{2 (2cos ^{2} \theta)} }$

$\rm= \sqrt{2 + \sqrt{4cos ^{2} \theta} }$

$\rm= \sqrt{2 + 2cos \theta }$

$\rm= \sqrt{2 (1 + cos \theta) }$

$\rm= \sqrt{2 (2cos^{2} ( \theta/2) }$

$\rm= \sqrt{4cos^{2} ( \theta/2) }$

$\rm= 2cos( \theta/2)$

LHS = RHS

Hence Proved

Check which of the following is a solution of 2x-Sy-10 A(0,2) (5,0) (8,5)

Answer»

Answer:

ANSWER

GIVEN EQUATION is 2x−5y=10

In RHS we have 2x−5y

Put the given (5,0) we get

2x−5y=10

2×5−5×0

10−0=10

Hence RHS=10 and LHS=10

Both are equal

8.	f(x)= xcosx - x^2, if the initial trial starts with 1, what will be the value of root after the second tria
Answer» Important Message for all The hot water you drink is good for your throat. But this corona virus is hidden behind the paranasal sinus of your nose for 3 to 4 DAYS. The hot water we drink does not reach there. After 4 to 5 days this virus that was hidden behind the paranasal sinus reaches your lungs. Then you have trouble breathing. That's why it is very important to take steam, which reaches the back of your paranasal sinus. You have to kill this virus in the nose with steam. At 50°C, this virus becomes disabled i.e. paralyzed. At 60°C this virus becomes so weak that any human immunity system can fight against it. At 70°C this virus dies completely. This is what steam does. The entire public health department knows this. But everyone wants to take advantage of this pandemic. So they don't share this information openly. One who stays at home should take steam once a day. If you go to the market to buy VEGETABLES, take it twice a day. Anyone who meets some people or goes to office should take steam 3 times a day. Forward this to all your loved ones. Steam week According to doctors, Covid -19 can be killed by inhaling steam from the nose and mouth, eliminating the Coronavirus. If all the people started a steam drive campaign for a week, the pandemic will soon end. So here is a suggestion: * Start the process for a week from 1st October to 8TH October, morning and evening, for just 5 minutes each time, to inhale steam. If all adopt this practice for a week the deadly Covid-19 will be erased. This practice has no side EFFECTS either. So PLEASE send this message to all your relatives, friends and neighbours, so that we all can kill this corona virus together and live and walk freely in this beautiful world. Thank you You are welcome to send this to your known groups / friends.

9.	If PQ is a tangent to a circle at Q with center O,then angle OPQ isA.45B.90C.120D.100
Answer» $\huge\underbrace{\overbrace{\boxed{\boxed{\mathfrak{Answer:}}}}}$ Given- O is the centre of a circle to which PQ is a tangent at P. ΔOPQ is isosceles whose VERTEX is P. To find out- ∠OQP=? Solution- OP is a radius through P, the point of contact of the tangent PQ with the given circle ∠OPQ=90° since the radius through the point of contact of a tangent to a circle is perpendicular to the tangent. Now ΔOPQ is isosceles whose vertex is P. ∴OP=PQ⟹∠OQP=∠QOP⟹∠OQP+∠QOP=2∠OQP. ∴ By ANGLE sum property of triangles, ∴∠OPQ+2∠OQP=180° ⟹90° +2∠OQP=180° ⟹∠OQP=45° . Ans- OPTION- A.

If PQ is a tangent to a circle at Q with center O,then angle OPQ isA.45B.90C.120D.100

Answer»

$\huge\underbrace{\overbrace{\boxed{\boxed{\mathfrak{Answer:}}}}}$

Given- O is the centre of a circle to which PQ is a tangent at P. ΔOPQ is isosceles whose VERTEX is P.

To find out- ∠OQP=?

Solution- OP is a radius through P, the point of contact of the tangent PQ with the given circle ∠OPQ=90°

since the radius through the point of contact of a tangent to a circle is perpendicular to the tangent. Now ΔOPQ is isosceles whose vertex is P.

∴OP=PQ⟹∠OQP=∠QOP⟹∠OQP+∠QOP=2∠OQP.

∴ By ANGLE sum property of triangles,

∴∠OPQ+2∠OQP=180°

⟹90°

+2∠OQP=180°

⟹∠OQP=45°

.

Ans- OPTION- A.

13.	If you give me a good answer i will give 50 pointsThe graph of f(x) = \|x – h\| + k contains the points (–6, –2) and (0, –2). The graph has a vertex at (h, –5). Describe how to find the value of h. Then, explain how this value translates the graph of the parent function.
Answer» Answer: The absolute function is symmetric with its vertex on the line of symmetry. Because the points (-6,-2) and (0,-2) have the same output, the points are the same distance from the line of symmetry. Midway between -6 and 0 is the value of -3. Therefore, the vertex must have an X- COORDINATE of -3, which is the value of H. This would TRANSLATE the graph of the parent function 3 to left. Hope it HELPS uhh dear.

31.	If alpha and ßare zeroes of the quadraticpolynomial 4x2 +4x + 1, thenform quadraticpolynomial whose zeroes are2 alpha and 2 beta
Answer» Step-by-step explanation: solve this lets divide the QUADRATIC equation by 4 such that we have it in the FORM x 2 +(α+β)x+αβ so after dividing by 4 we have 4 4x 2 +4x+1 x 2 +x+ 4 1 So we haveα+β=1 ...................(1) andαβ= 4 1 ..................(2) So if ZEROES to the new quadratic equation are 2α and 2β, then 2α+2β=2(α+β) =2(1)=2 .................... Using (1) and, 2α×2β=4αβ =4× 4 1 =1 .................... Using (2) So the new quadratic equation with its roots 2αand2β will be x 2 +(2α+2β)x+2α×2β Putting the values, the equation would be, x 2 +2x+1

If alpha and ßare zeroes of the quadraticpolynomial 4x2 +4x + 1, thenform quadraticpolynomial whose zeroes are2 alpha and 2 beta

Answer»

Step-by-step explanation:

solve this lets divide the QUADRATIC equation by 4 such that we have it in the FORM x

2

+(α+β)x+αβ

so after dividing by 4 we have

4

4x

2

+4x+1

x

2

+x+

4

1

So we haveα+β=1 ...................(1)

andαβ=

4

1

..................(2)

So if ZEROES to the new quadratic equation are 2α and 2β, then

2α+2β=2(α+β)

=2(1)=2 .................... Using (1)

and,

2α×2β=4αβ

=4×

4

1

=1 .................... Using (2)

So the new quadratic equation with its roots 2αand2β will be

x

2

+(2α+2β)x+2α×2β

Putting the values, the equation would be,

x

2

+2x+1

Soit can be written in the form a/b 3 + 2√5 = a/b Here a and b are coprime NUMBERS and b ≠ 0 Solving3 + 2√5 = a/b we get, =>2√5 = a/b – 3 =>2√5 = (a-3b)/b =>√5 = (a-3b)/2b This SHOWS (a-3b)/2b is a rational number. But we know that But √5 is an irrational number. so it contradictsour assumption.

√3-2√5 is a irrational number? Prove it ...

Answer»

Answer:

Prove that 3+2√5 is IRRATIONAL

Given:3 + 2√5

To prove:3 + 2√5 is an irrational NUMBER.

Proof:

Letus assume that 3 + 2√5 is a rational number.

Soit can be written in the form a/b

3 + 2√5 = a/b

Here a and b are coprime NUMBERS and b ≠ 0

Solving3 + 2√5 = a/b we get,

=>2√5 = a/b – 3

=>2√5 = (a-3b)/b

=>√5 = (a-3b)/2b

This SHOWS (a-3b)/2b is a rational number. But we know that But √5 is an irrational number.

so it contradictsour assumption.

Our assumption of3 + 2√5 is a rational number is incorrect.

3 + 2√5 is an irrational number

Hence proved.Ayushman1137
