First case:-tanx=5/12 = height of tower /distance (d) ---------------(1)

second case:-3/4 = height of tower /(d-192)-------(2)

from equation (1) and (2)

3 (d-192)/4=5d/12 9 (d-192)=5d9d - 1728=5d 4d=1728d=432 m

nowheight of tower =5 x 432/12 =5 x 36=180 m

a = 1 , d = 2

Sn = n/2 [ 2a + [n-1]d ] = n/2 [ 2 + 2n - 2 ] = n/2 [ 2n ] = n²

5 is the mode of the data

oh sorry instead of writing 5 is the value of k I wrote 5 is the mode. 5 is the value of k.

we know that:

volume of cube = a³

where, a is the side or length of edge of cube.

So, here

if the length of edges of cube is halved

=> side of cube = a / 2

=> volume = (a/2)³

= a³ / 2³

= a³ / 8

Hence

when the edge length is halved then the volume of cube become 1/8 of the volume before.

Hence ratio is 1/1/8=8:1option d

Parallel ATA, originally AT Attachment, is an interface standard for the connection of storage devices such as hard disk drives, floppy disk drives, and optical disc drives in computers. The standard is maintained by the X3/INCITS committee.

basically it's related to computer and uses in cpu

mode is the most frequently occurring data

and here 23 has occurred maximum no. of times that is 3 times

so, mode is. = 23.

The tectonic plates whose turbulent interactions formed Iceland, are the Eurasian tectonic plate and the North American tectonic plate. Spanning the Mid-Atlantic Ridge, Iceland emerged as a result of thedivergent, spreading, boundary between these two plates and the activity of Iceland´s own hotspot or mantle plume.Option-B

First match score = 180Second match score = 257Let third match score = n

Average score = (180 + 257 + n) / 3230 = (437 +n) /3n = 230*3 - 437n = 690 - 437 = 253

Score in third match should be 253

play ground that is rectangle ,here we have not to find are because Vijay will walk along its outer path so ....

2(l+B) =2(224+126) =2(350) =700m so here it is ask that Vijay is traveling 5 times and we find only total distance he covers if he walk on time so now....

5×700=3500m. i.e. 3.5 KM

ans will be 3500meters that is 3.5 km

perimeter of square is =224+126+224+126=700 for one roundfor 5 rounds=5×700 =3500m =3.5 km

like me and I will like you

how can u do second last line

mean after that

Which line??Please specify clearly

I have simply substituted the value of alpha beta gamma

how u put the value in last line

Wait.. I'll solve again with full step and post

so thanks Bhai where are you studying

2sec^2x-sec^4x-2cosec^2x+cosec^4x=(1-tan^8x)/tan^4x.

=sec^2x(2-sec^2x)-cosec^2x(2-cosec^2x) .

put sec^2x=1+tan^2x , cosec^2x =1+cot^2x.

=(1+tan^2x)(2–1-tan^2x)-(1+cot^2x)(2–1-cot^2x).

=(1+tan^2x)(1-tan^2x)-(1+cot^2x)(1-ccot^2x).

=1-tan^4x-1+cot^4x.

=cot^4x-tan^4x.

=1/tan^4x -tan^4x.

what is this question

4321 is the total sum of the money spent by Rahul

total amount spent by him =2845+1480 =4325. ans.

It is given that ,

principal ( p ) = Rs 8000

Rate of interest ( R ) = 10½ % p.a = 21/2 yrs

Time ( T ) = 2 years

number of times interest paid = n = 2

Amount = A

A = P( 1 + R/100 )ⁿ

A = 8000 ( 1 + 21/200 )²

A = 8000 ( 221/200 )²

A = ( 8000 × 48841 )/ 40000

A= Rs 9768.20

Compound Interest ( C . I ) = A - P

= Rs 1768.20

According to this question,Principal=Rs8000Rate=20/2Time=2 years

Simple Interest for the first year = 8000*20*1/100*2 = Rs 800Amount= Rs 8000 + Rs 800 =Rs 8800Simple Interest for the second year = 8800*20*1/100*2 = Rs 880Amount = Rs 8800 + Rs 880 = Rs 9680Compund Interest = Final value - Initial valueRs 9680 - Rs 8000 = Rs 1680

p=8000r=10 5 2t=2yearsI=PRT 100I =8000*10 5*2 100*2i=40*10*5*2i=4000

Letσ(n)σ(n)be the sum of divisor function.For1010to have a friendly pair we have to find another solution to

σ(5x)=9xσ(5x)=9x

6σ(x)=9x(Assuming (5,x)=1)6σ(x)=9x(Assuming (5,x)=1)

2σ(x)=3x2σ(x)=3x

Now Letx=2kpx=2kpwherep∈Np∈N,(p,z)=1(p,z)=1

2(2k+1−1)σ(p)=3⋅2kp2(2k+1−1)σ(p)=3⋅2kp

σ(p)p=3⋅2k−12k+1−1σ(p)p=3⋅2k−12k+1−1

Now as any number has atleast two prime factors one and itself hence ,

σ(p)p>1σ(p)p>1

⟹3⋅2k−1>2

Which can be showed impossible fork>0k>0.Now let us assume thatxxis in the formx=5t2kqx=5t2kq

2(5t+1−1)(2k+1−1)σ(q)4=3⋅5t⋅2k⋅q2(5t+1−1)(2k+1−1)σ(q)4=3⋅5t⋅2k⋅q

(5t+1−1)(2k+1−1)σ(q)=3⋅5t⋅2k+1⋅q(5t+1−1)(2k+1−1)σ(q)=3⋅5t⋅2k+1⋅q

σ(q)q=3⋅5t⋅2k+1(5t+1−1)(2k+1−1)σ(q)q=3⋅5t⋅2k+1(5t+1−1)(2k+1−1)

Which by proceeding as above ie. by the factσ(q)q>1σ(q)q>1can be shown not possible.Thus no friendly pair of1010is possible. Thus1010is solitary.

Let f(x) = sqrt(x)f'(x) = d/dx [ sqrt(x) ] = d/dx [x^(1/2) ] = (1/2) x^(-1/2) = 1 / 2 x^(1/2) = 1 / 2sqrt(x)

Let x=9sqrt(9)=3

sqrt(8.95)= f(8.95)= f(9) + (8.95-9) f'(9)= 3 + (-0.05) [1 / 2 sqrt(9)]= 3 - 0.05 / 6= 2.991667
