we have to DIFFERENTIATE

let y =

now differentiating with respect to x,

dy/DX = 2[(2tanx)/(tanx + cosx)]²¯¹ d{2tanx/(tanx + cosx)}/dx

= 4tanx/(tanx + cosx) [(tanx + cosx) d(2tanx)/dx - 2tanx d(tanx + cosx)/dx ]/(tanx + cosx)²

= 4tanx/(tanx + cosx)³ [(tanx + cosx)(2sec²x) - 2tanx(sec²x - sinx)]

= 4tanx/(tanx + cosx)³ [2tanx. sec²x + 2secx - 2tanx. sec²x + 2tanx . sinx]

= 4tanx/(tanx + cosx)³ [2secx + 2tanx. sinx ]

= 4tanx/(tanx + cosx)³ [2secx + 2secx. sin²x ]

= 4tanx/(tanx + cosx)³ [2secx (1 + sin²x)]

= {4tanx × [2secx (1 + sin²x)]} /(tanx + cosx)³

= 8tanx . secx(1 + sin²x)/(tanx + cosx)³

therefore DIFFERENTIATION of is

The correct question is :

"Tree Plantation Drive"

A Group Housing Society has 600 members, who have their houses in the campus and decided to hold a Tree Plantation Drive on the occasion of New YEAR. Each household was given the choice of planting a sampling of its choice. The number of different types of saplings planted were (i) Neem - 125 (ii) Peepal - 165 (iii) Creepers - 50 (iv) Fruit plants - 150 (v) Flowering plants - 110. On the opening ceremony, one of the plants is selected randomly for a prize. After reading the above passage, answer the following : What is the PROBABILITY that the selected plant is (i) A fruit plant or a flowering plant ? (ii) Either a Neem plant or a Peepal plant ?

(i) Probability of selecting a fruit plant or a flowering plant for prize = 13 / 30

(ii) Probability of selecting either a neem plant or a peepal plant for prize = 29 / 60

• Given,

Number of Neem saplings planted = 125

Number of Peepal saplings planted = 165

Number of Creeper saplings planted = 50

Number of Fruit plant saplings planted = 150

Number of Flowering plant saplings planted = 110

Total number of saplings planted = 125 + 165 + 50 + 150 + 110 = 600

• Probability of an event (P) = Number of favourable OUTCOMES / Total number of possible outcomes

(i) Probability of selecting a fruit plant or a flowering plant (P₁) = (Number of fruit plants + Number of flowering plants) / Total number of plants

=> P₁ = (150 + 110) / 600

=> P₁ = 260 / 600

=> P₁ = 13 / 30

(ii) Probability of selecting either a neem plant or a peepal plant (P₂) = (Number of neem plants + Number of peepal plants) / Total number of plants

=> P₂ = (125 + 165) / 600

=> P₂ = 290 / 600

=> P₂ = 29 / 60

ANSWER:

HOPE that this was CORRECT answer

Solution :-

Let us Assume That, her saving at the END of first month is Rs.X .

Now, in Next Month his saving is 5% greater than the PREVIOUS month’s TOTAL saving .

So,

→ Yui , Saving after End of second Month = Previous Month Saving + (5% of Previous Month Saving) = x + (5 % of x ) = x + (5*x/100) = x + 0.05x = 1.05x.

So, Yui Salary is 1.05 times of Previous Month salary.

_________________

Now, Lets Check Further also ,

→ Saving after End of Second Month = 1.05x .

→ Saving after end of Third month = Saving after end of second month + (5% of Saving after end of second month) = 1.05x + (5% of 1.05x)

= 1.05x + [ ( 5 * 1.05x)/100 ]

= 1.05x + 0.05 * 1.05x

= 1.05x ( 1 + 0.05)

= 1.05x * 1.05.

Hence, we can conclude That, Each month we have to multiply the previous AMOUNT with 1.05...

Answer:

An isosceles triangle is ONE in which has two equal sides. The ANGLES that are opposite the equal sides are ALSO equal. In an isosceles RIGHT triangle, one of the angles is a right triangle, which MEANS that it measures 90 degrees.

Step-by-step explanation:

Given In the adjacent figure find out the distance in kilometres  from C to B through E and A

• Given In the adjacent figure find out the distance in kilometres 1 from C to B through E and A  
• From the DIAGRAM ABCE is a parallelogram and ECD is a triangle. So given AB is 1350 km, BC = 2170 km, AC = 3250 km, AE = 1500 km, EC = 1490 km, CD = 2160 km and ED = 1280 km. Now we need to find from C to B through E and A.
• Therefore from C to B through E and A = 1490 km + 1500 km + 1350 km = 4340 km
