Differenciate w.r.t to x Ans:

Answer»

$\huge\bf{\red{\overbrace{\underbrace{\purple{Given:}}}}}$

★ $y=\dfrac{2}{<klux>X</klux>}+\frac{x}{2}$

$\huge\bf{\red{\overbrace{\underbrace{\purple{To\:\:Find:}}}}}$

★The DIFFERENTIATION of y W. R. t. x.

$\huge\bf{\red {\overbrace{\underbrace{\purple{Answer:}}}}}$

We have,

$y=\dfrac{2}{x}+\frac{x}{2}$

So,

$\implies \dfrac{dy}{dx} =\dfrac{d[\dfrac{2}{x}+\dfrac{x}{2}]}{dx}$

$\implies \dfrac{dy}{dx}=\dfrac{d[2x^{-1}+\frac{1}{2}(x) ]}{dx}$

$\implies \dfrac{dy}{dx}=\dfrac{d[2x^{-1}]}{dx}+\dfrac{1}{2}\dfrac{d[x]}{dx}$

$\implies \dfrac{dy}{dx}=2\frac{d[x^{-1}]}{dx}+\dfrac{1}{2}\times 1$

$\large\orange{\boxed{\bf{\purple{y=a^{n}, \dfrac{dy}{dx}=na^{n-1}}}}}$

$\implies \dfrac{dy}{dx}=-2x^{-2}+\dfrac{1}{2}$

8.	If we add 1 to the numerator and subtract 1 from the denominator, a fractionbecomes 1. It also becomes 1/2 if we only add 1 to the denominator. What is thefraction?
Answer» Answer: 3/5 Step-by-step EXPLANATION: Given :- If we add 1 to NUMERATOR, and subtract 1 from the denomination, a FRACTION reduce the 1. It becomes ½ if we only add 1 to the denominator. To Find :- The Fraction Solution :- Let the fraction be x/y According to the QUESTION, ⇒ x + 1/y - 1 = 1 ⇒ x - y = - 2 ... (i) ⇒ x/y + 1 = 1/2 ⇒ 2x - y = 1 ... (ii) Subtracting equation (i) from equation (ii), we get ⇒ x = 3 ... (iii) Putting this value in equation (i), we get ⇒ 3 - y = - 2 ⇒ -y = 5 ⇒ y = 5 Hence, the fraction is 3/5

8.

If we add 1 to the numerator and subtract 1 from the denominator, a fractionbecomes 1. It also becomes 1/2 if we only add 1 to the denominator. What is thefraction?

Answer»

Answer:

3/5

Step-by-step EXPLANATION:

Given :-

If we add 1 to NUMERATOR, and subtract 1 from the denomination, a FRACTION reduce the 1.

It becomes ½ if we only add 1 to the denominator.

To Find :-

The Fraction

Solution :-

Let the fraction be x/y

According to the QUESTION,

⇒ x + 1/y - 1 = 1

⇒ x - y = - 2 ... (i)

⇒ x/y + 1 = 1/2

⇒ 2x - y = 1 ... (ii)

Subtracting equation (i) from equation (ii), we get

⇒ x = 3 ... (iii)

Putting this value in equation (i), we get

⇒ 3 - y = - 2

⇒ -y = 5

⇒ y = 5

Hence, the fraction is 3/5

<P>Answer:

9 വർഷം

Step-by-step EXPLANATION:

'p' ആരംഭ പ്രിൻസിപ്പലാകട്ടെ.

3 വർഷത്തിനുശേഷം, തുക = 2P

ഇത് പലിശ കൂട്ടുന്നതിനാൽ, ഓരോ തുല്യ സമയ പരിധിക്കും ഞങ്ങൾ ഒരേ ഘടകത്താൽ ഗുണിച്ചുകൊണ്ടിരിക്കും (ലളിതമായ താൽപ്പര്യത്തിൽ നിന്ന് വ്യത്യസ്തമായി ഓരോ തുല്യ സമയ പരിധിക്കും ഞങ്ങൾ ഒരേ തുക ചേർക്കുന്നു).

അതിനാൽ, മറ്റൊരു 3 വർഷത്തിനുശേഷം, നൽകാൻ ഇത് വീണ്ടും ഇരട്ടിയാകുന്നു

2 × 2p = 4P

മറ്റൊരു 3 വർഷത്തിനുശേഷം, അത് നൽകുന്നത് ഇരട്ടിയാക്കുന്നു

2 × 4p = 8p

ഇതിന് ആകെ 9 വർഷം എടുക്കും

Answer» Answer: i really work hard for your answer Step-by-step explanation: Area of triangle ABC = 1/2 ×BASE × HEIGHT = 1/2 × AB × AC = 1/2 × 4× 4 = 2 × 4 = 8 cm square LET AD IS PERPENDICULAR TO BC In Triangle ADB AND ADC AD = AD ( common) ANGLE ADC = angle ADB ( each 90 degree) AB = AC (Given) Triangle ADB (congruent to). triangle ADC ( RHS criteria) BD = CD ( cpct ) in triangle ABC , BY Pythagoras theorem ABsquare + ACsquare = BC square 4 square +4 square = BCsquare 16 +16 = BCsquare 32 = BC square :. BC = 4√2 cm BD + CD = BC 2BD = BC (. BD = CD ) 2BD = 4√2 BD = 2√2 cm now in triangle BAD , by Pythagoras theorem ADsquare + BD square = ABsquare ADsquare + 2√2 square = 4 square ADsquare + 4×2 = 16 ADsquare + 8 = 16 ADsquare = 16- 8 ADsquare = 8 .: AD = √8 .: AD = 2√2 cm Hence length of perpendicular from A to BC = length of AD = 2√2 cm

39.

The area of triangulation ABC is 8cm square in which Ab=Ac=4cm and angle A = 90 degree

Answer»

Answer:

i really work hard for your answer

Step-by-step explanation:

Area of triangle ABC = 1/2 ×BASE × HEIGHT

= 1/2 × AB × AC

= 1/2 × 4× 4

= 2 × 4

= 8 cm square

LET AD IS PERPENDICULAR TO BC

In Triangle ADB AND ADC

AD = AD ( common)

ANGLE ADC = angle ADB ( each 90 degree)

AB = AC (Given)

Triangle ADB (congruent to). triangle ADC ( RHS criteria)

BD = CD ( cpct )

in triangle ABC , BY Pythagoras theorem

ABsquare + ACsquare = BC square

4 square +4 square = BCsquare

16 +16 = BCsquare

32 = BC square

:. BC = 4√2 cm

BD + CD = BC

2BD = BC (. BD = CD )

2BD = 4√2

BD = 2√2 cm

now in triangle BAD , by Pythagoras theorem

ADsquare + BD square = ABsquare

ADsquare + 2√2 square = 4 square

ADsquare + 4×2 = 16

ADsquare + 8 = 16

ADsquare = 16- 8

ADsquare = 8

.: AD = √8

.: AD = 2√2 cm

Hence length of perpendicular from A to BC = length of AD = 2√2 cm
