Let x be the height of the tower. As shown in the figure, let A be the initial position and B be the final position. Then,

h/192 + x = 5/12 ⋯ 12h = 960 + 5x ⋯⋯(1)

h/x = 3/4 4h = 3x x = 4h/3

Substituting the value of x in (1) 12h = 960 + 5 × 4h/3 12h = 960 + 20h/336h = 2880 + 20h 16h = 2880 h = 2880/16 = 180m

148 is correct answer

Thank you so much

1. x - 1 = 0= x = 1.p(1) = 1^4 - 3*1^2 + 2 * 1 = 1 - 3 + 2 + 1 = 1.

2. x - 1 = 0= x = 1.p(1) = 1^3 + 3*1^2-12*1+4 = 1+3-12+4= - 4.

3. x + 1 = 0= x = -1.p(-1) = (-1)^4 + 1= 1+1 = 2.

Given series 4, 7, 10,...... 148 is an AP

First term a = 4, common difference d = 7 - 4 = 3

nth term of AP is given byan = a + (n - 1)d

Let number of terms in series be mso,148 = 4 + (m-1)3148 = 4 + 3m - 33m = 148 - 13m = 147m = 147/3 = 49

Therefore,Number of terms in given series is 49

Given -AP = 4,7,10,......,148First term ( a ) = 4 common difference (d) = 7-4=3n term of AP is indicated by an = a+(n-1)d an = 148 ( given )148 = 4+(n-1)3148 = 4+3n-3147 = 3n147/3 = n49 = nSo, no. of terms are 49.

let the speed of the boat be x and the speed of stream be y

30/x-y + 28/x+y =7

21/x-y + 21/x+y=5

therefore 1/x-y=a,1/x+y=b

30a+28b=7...(1)×21

21a+21b=5.....(2)×30

630a+588b=147

630a+630b=150

(1)-(2/

-42b=-3

b=1/14

substituting the value of b in(1)

a=1/6

a=1/x-y

1/6=1/x-y

x-y=6...(.3)

b=1/x+y

1/14=1/x+y

x+y=14......(4)

(3)+(4)

2x=20

x=10

x+y=14

y=14-10=4

therefore speed of boat in still water is 10km/hr and speed of stream is 4km/hr

∫ 2x/(1 + x²) dx ....(1)

Let 1 + x² = t

2xdx = dt

∫ 1/t dt

log (t) + C

put t = 1 + x²

log ( 1 + x²)

the answer for this question is 0.8

Let the side of an equilateral triangle is a

perimeter of equilateral triangle= area of equilateral triangle

3a= (√3/4)a^2a= (4×3)/√3a= (4×3)×√3/ √3×√3. ( by rationalising)a= 4√3side = 4√3= 4×1.73=6.92

In mathematics, an ellipse is a curve in a plane surrounding two focal points such that the sum of the distances to the two focal points is constant for every point on the curve. ... An ellipse may also be defined analytically as the set of points for each of which the sum of its distances to two foci is a fixed number.
