Sia ? 4 years, 6 months ago (6945213)

Lets take assumed mean, A as 16

Class interval =2

∴ui​=hxi​−A​=2xi​−16​

Now, we have A=16,xˉ=18 and h=2

We know that,

Mean, xˉ=A+h(N1​∑fi​ui​)

⇒18=16+2(f+442f+24​)

⇒f+442f+24​=1

⇒f+44=2f+24

⇒f=20

Hence, the value of missing frequency, f=20

SinA= cotA/cosA. SecA= cot A×SineA Tan A =1/cotA

Gouri Yaswanth Kumar 4 years, 6 months ago (11376576)

To convert the given trigonometric ratios in terms of cot functions, use trigonometric formulas We know that, cosec2A – cot2A = 1 cosec2A = 1 + cot2A Since cosec function is the inverse of sin function, it is written as 1/sin2A = 1 + cot2A Now, rearrange the terms, it becomes sin2A = 1/(1+cot2A) Now, take square roots on both sides, we get sin A = ±1/(√(1+cot2A) The above equation defines the sin function in terms of cot function Now, to express sec function in terms of cot function, use this formula sin2A = 1/ (1+cot2A) Now, represent the sin function as cos function 1 – cos2A = 1/ (1+cot2A) Rearrange the terms, cos2A = 1 – 1/(1+cot2A) ⇒cos2A = (1-1+cot2A)/(1+cot2A) Since sec function is the inverse of cos function, ⇒ 1/sec2A = cot2A/(1+cot2A) Take the reciprocal and square roots on both sides, we get ⇒ sec A = ±√ (1+cot2A)/cotA Now, to express tan function in terms of cot function tan A = sin A/cos A and cot A = cos A/sin A Since cot function is the inverse of tan function, it is rewritten as tan A = 1/cot A

Yes ! garbage is the lifeline of the rag pickers as it helps to make their life from the garbage. as it helps in money, to ensure, and helps in lifeline of it

Musicophile ❤️? 4 years, 6 months ago (2677443)

The ragpickers live in the outskirts of Delhi, i.e. Seemapuri. These people live in abject poverty. The little children who should be going to school at such a tender age, are forced to practice ragpicking, as they cannot afford even the basic necessities of life. They wear torn clothes and consider themselves lucky even if they find worn out shoes. They rummage through the garbage heaps, and it brings a smile on their faces if they find a rupee and continue the work in hope of finding more.

From the ant’s principle, we learn that we should save enough for the future, so that we might not need to borrow or lend from anyone in times of need. We should toil hard when the sun shines and make the best utilization of time and available resources.

Medieval technology is the technology used in medieval Europe under Christian rule. After the Renaissance of the 12th century, medieval Europe saw a radical change in the rate of new inventions, innovations in the ways of managing traditional means of production, and economic growth. The period saw major technological advances, including the adoption of gunpowder, the invention of vertical windmills, spectacles, mechanical clocks, and greatly improved water mills, building techniques (Gothic architecture, medieval castles), and agriculture in general (three-field crop rotation).

The development of water mills from their ancient origins was impressive and extended from agriculture to sawmills both for timber and stone. By the time of the Domesday Book, most large villages had turnable mills, around 6,500 in England alone. Water-power was also widely used in mining for raising ore from shafts, crushing ore, and even powering bellows.
