2/5x square-x-3/5=0please answer fast no spam

Answer»

Step-by-step explanation:

GIVEN, 2/5 x2 - x - 3/5 = 0

⇒ 2X2 - 5x – 3 = 0

By SPLITTING the MIDDLE term,

⇒ 2x2 - 6x + x – 3 = 0

Taking common in the expression,

⇒ 2x (x - 3) + 1 (x - 3) = 0

⇒ (2x + 1) (x - 3) = 0

∴ 2x + 1 = 0 and ∴ x – 3 = 0

∴ x = -1/2 and ∴ x = 3

3662.

सौ पांव सत्तर आंखी, कितने मुर्गा कितने हाथी।

Answer»

HATHI = H

murga = M

hathi ke PAIR = 4H

hathi ki aakh = 2H

Murge ke pair = 2M

Murge ki aakhe = 2M

hathi ke pair + Murge ke pair = pair

4H + 2H = 100

2H + M = 50

hathi ki aakh + murge ki aakhe = aakh

2H + 2M = 72

2H + M = 36

(2H+M) - (H+M) = 50-36

H= 14

14+M= 36

M = 22

hathi = 14

Murge = 22

3664.	: Find the length of the are of y2 = x3 from x = of y2 = x3 from x = 0 to x = 5. Given equation of the curve
Answer» $\large\underline{\sf{Solution-}}$ Given CURVE is $\red{\rm :\longmapsto\: {y}^{2} = {x}^{3}}$ can be rewritten as $\rm :\longmapsto\:y = \sqrt{ {x}^{3} }$ So, curve is to be considered in first quadrant to find the length of arc from x = 0 to x = 5. Now, On differentiating both SIDES w. r. t. x, we get $\rm :\longmapsto\:\dfrac{dy}{dx} = \dfrac{1}{2 \sqrt{ {x}^{3} } }\dfrac{d}{dx} {x}^{3}$ $\rm :\longmapsto\:\dfrac{dy}{dx} = \dfrac{1}{2 \sqrt{ {x}^{3} } } {3x}^{2}$ $\bf\implies \:\dfrac{dy}{dx} = \dfrac{3}{2} \sqrt{x}$ Now, we KNOW Length of arc y = f(x) from x = a to x = B is given by $\red{\rm :\longmapsto\:Length \: of \: arc \: = \displaystyle\int ^b_a \: \sqrt{1 + {\bigg(\dfrac{dy}{dx} \bigg) }^{2} } dx}$ So, on substituting the values, we get $\red{\rm :\longmapsto\:Length \: of \: arc \: = \displaystyle\int ^5_0 \: \sqrt{1 + {\bigg(\dfrac{9x}{4} \bigg) } } dx}$ $\red{\rm :\longmapsto\:Length \: of \: arc \: = \displaystyle\int ^5_0 \: \sqrt{\dfrac{4 + 9x}{4}} dx}$ $\red{\rm :\longmapsto\:Length \: of \: arc \: = \dfrac{1}{2} \displaystyle\int ^5_0 \: \sqrt{4 + 9x} dx}$ $\red{\rm :\longmapsto\:Length \: of \: arc = \dfrac{1}{2} \times \dfrac{ {\bigg(4 + 9x \bigg) }^{\dfrac{3}{2} } }{\dfrac{3}{2} \times 9 }\bigg \|^5_0}$ $\red{\rm :\longmapsto\:Length \: of \: arc = \dfrac{1}{27} \times {\bigg(4 + 9x \bigg) }^{\dfrac{3}{2} }\bigg \|^5_0}$ $\red{\rm :\longmapsto\:Length \: of \: arc = \dfrac{1}{27} \bigg \|{\bigg(4 + 45 \bigg) }^{\dfrac{3}{2} } - {\bigg(4 + 0 \bigg) }^{\dfrac{3}{2} }}\bigg \|$ $\red{\rm :\longmapsto\:Length \: of \: arc = \dfrac{1}{27} \bigg \|{\bigg(49 \bigg) }^{\dfrac{3}{2} } - {\bigg(4 \bigg) }^{\dfrac{3}{2} }}\bigg \|$ $\red{\rm :\longmapsto\:Length \: of \: arc = \dfrac{1}{27} \bigg \|{\bigg( {7}^{2} \bigg) }^{\dfrac{3}{2} } - {\bigg( {2}^{2} \bigg) }^{\dfrac{3}{2} }}\bigg \|$ $\red{\rm :\longmapsto\:Length \: of \: arc = \dfrac{1}{27} \bigg \|343 - 8\bigg \|}$ $\red{\rm :\longmapsto\:Length \: of \: arc = \dfrac{1}{27} \bigg \|335\bigg \|}$ $\red{\rm :\longmapsto\:Length \: of \: arc = \dfrac{335}{27} \: units}$

: Find the length of the are of y2 = x3 from x = of y2 = x3 from x = 0 to x = 5. Given equation of the curve

Answer»

$\large\underline{\sf{Solution-}}$

Given CURVE is

$\red{\rm :\longmapsto\: {y}^{2} = {x}^{3}}$

can be rewritten as

$\rm :\longmapsto\:y = \sqrt{ {x}^{3} }$

So, curve is to be considered in first quadrant to find the length of arc from x = 0 to x = 5.

Now,

On differentiating both SIDES w. r. t. x, we get

$\rm :\longmapsto\:\dfrac{dy}{dx} = \dfrac{1}{2 \sqrt{ {x}^{3} } }\dfrac{d}{dx} {x}^{3}$

$\rm :\longmapsto\:\dfrac{dy}{dx} = \dfrac{1}{2 \sqrt{ {x}^{3} } } {3x}^{2}$

$\bf\implies \:\dfrac{dy}{dx} = \dfrac{3}{2} \sqrt{x}$

Now, we KNOW Length of arc y = f(x) from x = a to x = B is given by

$\red{\rm :\longmapsto\:Length \: of \: arc \: = \displaystyle\int ^b_a \: \sqrt{1 + {\bigg(\dfrac{dy}{dx} \bigg) }^{2} } dx}$

So, on substituting the values, we get

$\red{\rm :\longmapsto\:Length \: of \: arc \: = \displaystyle\int ^5_0 \: \sqrt{1 + {\bigg(\dfrac{9x}{4} \bigg) } } dx}$

$\red{\rm :\longmapsto\:Length \: of \: arc \: = \displaystyle\int ^5_0 \: \sqrt{\dfrac{4 + 9x}{4}} dx}$

$\red{\rm :\longmapsto\:Length \: of \: arc \: = \dfrac{1}{2} \displaystyle\int ^5_0 \: \sqrt{4 + 9x} dx}$

$\red{\rm :\longmapsto\:Length \: of \: arc = \dfrac{1}{2} \times \dfrac{ {\bigg(4 + 9x \bigg) }^{\dfrac{3}{2} } }{\dfrac{3}{2} \times 9 }\bigg |^5_0}$

$\red{\rm :\longmapsto\:Length \: of \: arc = \dfrac{1}{27} \times {\bigg(4 + 9x \bigg) }^{\dfrac{3}{2} }\bigg |^5_0}$

$\red{\rm :\longmapsto\:Length \: of \: arc = \dfrac{1}{27} \bigg |{\bigg(4 + 45 \bigg) }^{\dfrac{3}{2} } - {\bigg(4 + 0 \bigg) }^{\dfrac{3}{2} }}\bigg |$

$\red{\rm :\longmapsto\:Length \: of \: arc = \dfrac{1}{27} \bigg |{\bigg(49 \bigg) }^{\dfrac{3}{2} } - {\bigg(4 \bigg) }^{\dfrac{3}{2} }}\bigg |$

$\red{\rm :\longmapsto\:Length \: of \: arc = \dfrac{1}{27} \bigg |{\bigg( {7}^{2} \bigg) }^{\dfrac{3}{2} } - {\bigg( {2}^{2} \bigg) }^{\dfrac{3}{2} }}\bigg |$

$\red{\rm :\longmapsto\:Length \: of \: arc = \dfrac{1}{27} \bigg |343 - 8\bigg |}$

$\red{\rm :\longmapsto\:Length \: of \: arc = \dfrac{1}{27} \bigg |335\bigg |}$

$\red{\rm :\longmapsto\:Length \: of \: arc = \dfrac{335}{27} \: units}$

3698.	The salaries of ram and his brother are in the ratio 5:6 respectively . The salary of Ram's brother is Rs 32,000 per month
Answer» APPROPRIATE Question : The salaries of ram and his brother are in the ratio 5:6 respectively . The salary of Ram's brother is Rs 32,000 per month. What is the salary of Ram per month? Step-by-step explanation: As per the provided information in the given question, we have : The salaries of Ram and his brother are in the ratio 5:6 respectively. The salary of Ram's brother is Rs 32,000 per month. We are asked to calculate the salary of Ram per month. ― According to the question, the salaries of Ram and his brother are in the ratio 5:6 respectively. So, let us suppose the salary of Ram as 5x and the salary of his brother as 6x. Also, according to the question, the salary of Ram's brother is Rs 32,000 per month. As according to the first statement, Ram's brother's salary is 6x but according to the second statement, his salary is Rs 32,000 per month. Observing both statements, we can say that, $\longrightarrow \sf{\quad {6x = Rs. \; 32000 }} \\$ Transposing 6 from L.H.S to R.H.S. Since we are performing TRANSPOSITION method, so its arithmetic operator will get changed. $\longrightarrow \sf{\quad {x = \cancel{\dfrac {Rs. \;32000}{6}} }} \\$ Dividing Rs. 32000 by 6 to FIND the VALUE of x. $\longrightarrow \quad {\textbf{\textsf{x = Rs. \; 5333.33} }} \\$ $\underline{ \qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad} \\$ Now, as we have ASSUMED the salary of Ram as 5x. So, substitute the value of x and multiply it with 5 to find his salary. $\longrightarrow \sf{\quad {Salary \; of \; Ram = Rs. \; 5x }} \\$ Substitute the value of x. $\longrightarrow \sf{\quad {Salary \; of \; Ram = Rs. \; 5(5333.33) }} \\$ Multiplying the terms. $\longrightarrow \quad \underline{\boxed{\textbf{\textsf{ Salary \; of \; Ram = Rs. \; 26666.66}}}} \\$ Therefore, ⠀⠀⠀★ Ram's Salary = Rs. 26666.66

APPROPRIATE Question : The salaries of ram and his brother are in the ratio 5:6 respectively . The salary of Ram's brother is Rs 32,000 per month. What is the salary of Ram per month?

Step-by-step explanation:

As per the provided information in the given question, we have :

The salaries of Ram and his brother are in the ratio 5:6 respectively.
The salary of Ram's brother is Rs 32,000 per month.

We are asked to calculate the salary of Ram per month.

― According to the question, the salaries of Ram and his brother are in the ratio 5:6 respectively. So, let us suppose the salary of Ram as 5x and the salary of his brother as 6x.

Also, according to the question, the salary of Ram's brother is Rs 32,000 per month. As according to the first statement, Ram's brother's salary is 6x but according to the second statement, his salary is Rs 32,000 per month. Observing both statements, we can say that,

$\longrightarrow \sf{\quad {6x = Rs. \; 32000 }} \\$

Transposing 6 from L.H.S to R.H.S. Since we are performing TRANSPOSITION method, so its arithmetic operator will get changed.

$\longrightarrow \sf{\quad {x = \cancel{\dfrac {Rs. \;32000}{6}} }} \\$

Dividing Rs. 32000 by 6 to FIND the VALUE of x.

$\longrightarrow \quad {\textbf{\textsf{x = Rs. \; 5333.33} }} \\$

$\underline{ \qquad\qquad\qquad\qquad\qquad\qquad\qquad\qquad} \\$

Now, as we have ASSUMED the salary of Ram as 5x. So, substitute the value of x and multiply it with 5 to find his salary.

$\longrightarrow \sf{\quad {Salary \; of \; Ram = Rs. \; 5x }} \\$

Substitute the value of x.

$\longrightarrow \sf{\quad {Salary \; of \; Ram = Rs. \; 5(5333.33) }} \\$

Multiplying the terms.

$\longrightarrow \quad \underline{\boxed{\textbf{\textsf{ Salary \; of \; Ram = Rs. \; 26666.66}}}} \\$

Therefore,

⠀⠀⠀★ Ram's Salary = Rs. 26666.66

3700.

The price of a car is 3,25,000. It was insured to 80% of the price. The car was damaged completely in an accident and the insurance company paid 90% of the insurance. What was the difference between the price of the car and the amount received?

Answer»

91,000

Step-by-step explanation:

price of CAR = 3,25,000

insured price = 3,25,000*80/100 = 2,60,000

paid INSURANCE by COMPANY

= 2,60,000*90/100 = 2,34,000

price of car- amount RECEIVED

=3,25,000 -2,34,000 = 91,000
