9.	Cosx/11+cos3x/11+cos5x/11+cos7x/11+cos9x/11
Answer» CosA+cosB=2COS(A+B/2)cos(A-B/2) And cos(-x)=cosx are required formulas for this. cos x/11+cos9x/11= 2cos(5x/11)cos(-4x/11)..(1) cos 3x/11+cos 7x/11=2cos(5x/11)cos(-2x/11)..(2). cos(5x/11)..(3) So add three quantities (1),(2) and(3). TAKE cos(5x/11) common from three then we will get cos(5x/11)(2cos(4x/11)+2cos(2x/11)+1) => cos(5x/11)(4 cos (3x/11)cos(x/11) +1).

Answer» Total number of egg CRATES = 12 DOZEN = 12 x 12 = 144 Number of egg crates rotten = ⁷/₂₄ x 144 = 42 Number of egg crates to be sent back = ¹/₃ x 144 = 48 Total egg crates that can be used = 144 - 42 - 48 = 54 Hope it helps!!

10.

Pls give rhe answer for this question

Answer»

Total number of egg CRATES = 12 DOZEN = 12 x 12 = 144

Number of egg crates rotten = ⁷/₂₄ x 144 = 42

Number of egg crates to be sent back = ¹/₃ x 144 = 48

Total egg crates that can be used = 144 - 42 - 48 = 54

Hope it helps!!

20.	If sinθ=-5/13 and 180°
Answer» The ANGLE θis in 3rd QUADRANT where only tanθ is POSITIVE while other TRIGONOMETRIC ratios are all negative. Now, sinθ=5/13⇒cosθ=−√(1−sin2θ)=−√(1−25/169)=−√144/169=−12/13⇒tanθ=+5/12 cotθ=+12/5. cosecθ=−1/sinθ=−13/5 So, 5cot^2θ+12tanθ+13cosecθ=5∗144/25+12∗5/12+13∗−13/5 =144/5+5−169/5 =0

20.

If sinθ=-5/13 and 180°

Answer»

The ANGLE θis in 3rd QUADRANT where only tanθ is POSITIVE while other TRIGONOMETRIC ratios are all negative.

Now, sinθ=5/13⇒cosθ=−√(1−sin2θ)=−√(1−25/169)=−√144/169=−12/13⇒tanθ=+5/12

cotθ=+12/5. cosecθ=−1/sinθ=−13/5

So, 5cot^2θ+12tanθ+13cosecθ=5∗144/25+12∗5/12+13∗−13/5

=144/5+5−169/5

=0

Answer» Answer: वह अपनी जेब में 2375/- ले गया था l Explanation: He carried back home 5000 Rs. So, he must have had Rs.7000 in his POCKET to gift his third sister Rs. 2000 out of that. Now, third sister had added equal amount of MONEY in his pocket. This means he carried 7000/2 = 3500 Rs.in his pocket while coming to third sister house. Now, SIMILARLY, he had 3500 +2000= Rs. 5500 in his pocket to give Rs. 2000 to his second sister. And, second sister has added 5500/2 = Rs. 2750 in his pocket On the very same lines, He must have had Rs.2750 + 2000 = Rs. 4750 in his pocket to gift his first sister Rs. 2000. Even first sister added same amount. So, amount he had in his pocket was 4750/2 = Rs. 2375

Answer»

Answer:

वह अपनी जेब में 2375/- ले गया था l

Explanation:

He carried back home 5000 Rs.

So, he must have had Rs.7000 in his POCKET to gift his third sister Rs. 2000 out of that.

Now, third sister had added equal amount of MONEY in his pocket.

This means he carried 7000/2 = 3500 Rs.in his pocket while coming to third sister house.

Now, SIMILARLY, he had 3500 +2000= Rs. 5500 in his pocket to give Rs. 2000 to his second sister.

And, second sister has added 5500/2 = Rs. 2750 in his pocket

On the very same lines,

He must have had Rs.2750 + 2000 = Rs. 4750 in his pocket to gift his first sister Rs. 2000.

Even first sister added same amount.

So, amount he had in his pocket was 4750/2 = Rs. 2375

Answer» Let the distance travelled by x KM. Then, x-x = 2 10 15 3X - 2x = 60 x = 60 km. Time taken to travel 60 km at 10 km/hr = 60 hrs = 6 hrs. 10 So, Robert started 6 HOURS before 2 P.M. i.e., at 8 A.M. Required speed = 60 kmph. = 12 kmph. answer 12 km/h

Robert is travelling on a cycle and its calculate to reach point a at 2 p.m. if we travel at in kilometre per hour however he will reach there at 12 noon if you travel at 15 km per hour at what speed must be travel to reach at 1:00 p.m.?

Answer»

Let the distance travelled by x KM.

Then, x-x = 2

10 15

3X - 2x = 60

x = 60 km.

Time taken to travel 60 km at 10 km/hr = 60 hrs = 6 hrs.

10

So, Robert started 6 HOURS before 2 P.M. i.e., at 8 A.M.

Required speed = 60 kmph. = 12 kmph.

answer 12 km/h

35.

If A = cos^2θ + sin^4θ, then prove that for all values of θ, 3/4≤A≤1.

Answer»

GIVEN,

A=cos^2θ+sin^4θ

⟹A=1−sin^2θ+sin^4θ

⟹A=1+(sin^4θ−2⋅sin^2θ⋅1/2+1/4)−1/4

⟹A=(sinθ−1/2)^2+3/4

We know,

0≤sin^2θ≤1,∀θ∈R.

∴0≤(sin2θ−1/2)2≤1/4

⟹0+3/4≤(sinθ−1/2)2+3/4≤14+3/4

∴3/4≤A≤1.(∀θ∈R)†
