12.	Find the value of x for which point A(x/5),2) is the midpoint of the line segment joining the point P(-5,4)andR(-1,0)
Answer» GIVEN: P (-5, 4) R (-1, 0) Midpoint → A (x/5, 2) To find: Value of x = ? Solution: Apply Midpoint formula for X coordinate: Midpoint = (x₁ + x₂) ÷ 2 ⇒ Midpoint = (-5 - 1) ÷ 2 ⇒ x/5 = (-6) ÷ 2 ⇒ x/5 = -3 ⇒ x = -15 ∴ x = -15 VERIFICATION: Similarly, if we apply Midpoint formula for Y axis, Midpoint = (y₁ + y₂) ÷ 2 ⇒ Midpoint = (4 + 0) ÷ 2 ⇒ Midpoint = 4 ÷ 2 ⇒ 2 = 2 The given value is EQUAL to the derived value ★ Hence VERIFIED ★

12.

Find the value of x for which point A(x/5),2) is the midpoint of the line segment joining the point P(-5,4)andR(-1,0)

Answer»

GIVEN:

P (-5, 4)
R (-1, 0)
Midpoint → A (x/5, 2)

To find:

Value of x = ?

Solution:

Apply Midpoint formula for X coordinate:

Midpoint = (x₁ + x₂) ÷ 2

⇒ Midpoint = (-5 - 1) ÷ 2

⇒ x/5 = (-6) ÷ 2

⇒ x/5 = -3

⇒ x = -15

∴ x = -15

VERIFICATION:

Similarly, if we apply Midpoint formula for Y axis,

Midpoint = (y₁ + y₂) ÷ 2

⇒ Midpoint = (4 + 0) ÷ 2

⇒ Midpoint = 4 ÷ 2

⇒ 2 = 2

The given value is EQUAL to the derived value

★ Hence VERIFIED ★

14.	Root mean square of f(x)=x^2in (0,π)
Answer» The MEAN square of a function $f(x)$ in the interval (a, B) or [a, b] is GIVEN by, $\overline{x^2}=\dfrac{\displaystyle\int\limits_a^b[f(x)]^2\ dx}{\displaystyle\int\limits_a^bdx}$ And, well, the root mean square is given by, $x_{rms}=\sqrt{\overline{x^2}}$ Here the mean square of the function $f(x)=x^2$ in the interval (0, π) will be, $\longrightarrow\overline{x^2}=\dfrac{\displaystyle\int\limits_0^\pi[f\left(x\right)]^2\ dx}{\displaystyle\int\limits_0^\pi dx}$ $\longrightarrow\overline{x^2}=\dfrac{\displaystyle\int\limits_0^\pi\left(x^2\right)^2\ dx}{\displaystyle\int\limits_0^\pi dx}$ $\longrightarrow\overline{x^2}=\dfrac{\displaystyle\int\limits_0^\pi x^4\ dx}{\displaystyle\int\limits_0^\pi dx}$ $\longrightarrow\overline{x^2}=\dfrac{\dfrac{1}{5}\left[x^5\right]_0^\pi}{\big[x\big]_0^\pi}$ $\longrightarrow\overline{x^2}=\dfrac{\dfrac{1}{5}\cdot\pi^5}{\pi}$ $\longrightarrow\overline{x^2}=\dfrac{\pi^4}{5}$ HENCE the root mean square will be, $\longrightarrow x_{rms}=\sqrt{\overline{x^2}}$ $\longrightarrow x_{rms}=\sqrt{\dfrac{\pi^4}{5}}$ $\longrightarrow\underline{\underline{x_{rms}=\dfrac{\pi^2}{\sqrt5}}}$

Root mean square of f(x)=x^2in (0,π)

Answer»

The MEAN square of a function $f(x)$ in the interval (a, B) or [a, b] is GIVEN by,

$\overline{x^2}=\dfrac{\displaystyle\int\limits_a^b[f(x)]^2\ dx}{\displaystyle\int\limits_a^bdx}$

And, well, the root mean square is given by,

$x_{rms}=\sqrt{\overline{x^2}}$

Here the mean square of the function $f(x)=x^2$ in the interval (0, π) will be,

$\longrightarrow\overline{x^2}=\dfrac{\displaystyle\int\limits_0^\pi[f\left(x\right)]^2\ dx}{\displaystyle\int\limits_0^\pi dx}$

$\longrightarrow\overline{x^2}=\dfrac{\displaystyle\int\limits_0^\pi\left(x^2\right)^2\ dx}{\displaystyle\int\limits_0^\pi dx}$

$\longrightarrow\overline{x^2}=\dfrac{\displaystyle\int\limits_0^\pi x^4\ dx}{\displaystyle\int\limits_0^\pi dx}$

$\longrightarrow\overline{x^2}=\dfrac{\dfrac{1}{5}\left[x^5\right]_0^\pi}{\big[x\big]_0^\pi}$

$\longrightarrow\overline{x^2}=\dfrac{\dfrac{1}{5}\cdot\pi^5}{\pi}$

$\longrightarrow\overline{x^2}=\dfrac{\pi^4}{5}$

HENCE the root mean square will be,

$\longrightarrow x_{rms}=\sqrt{\overline{x^2}}$

$\longrightarrow x_{rms}=\sqrt{\dfrac{\pi^4}{5}}$

$\longrightarrow\underline{\underline{x_{rms}=\dfrac{\pi^2}{\sqrt5}}}$

27.

At what rate per cent per annum will a sum of Rs 500 amount to Rs 8427 in 2 years, compounded annually? (a) 4 % (b) 5 % (c) 6 % (d) 8 %

Answer»

ANSWER:

Correct OPTION is

C

6%

We have,

P=7500 Rs

A=8427 Rs

T=2 years

A=P(1+100R)T

7500+8427=7500(1+100R)T

75008427=(1+100R)2

(1+100R)=25002809=(5053)

(1+100R)=5053−1

100R=5053−1

R=503

R %=6 %

Hence 6% ( C) is correct ANS

$\huge \fbox \orange{Solutions:}$

$1. \: \sqrt{45} - 3 \sqrt{20} + 4√5$

$\sf \colorbox{pink} {<klux>ANSWER</klux>. 1}$

$\sqrt{45} - 3 \sqrt{20} + 4√5$

$= \sqrt{3 \times 3 \times 5} - 3 \sqrt{2 \times 2 \times 5} + 4 \sqrt{5}$

$= 3 \sqrt{5} - 3 \times 2 \sqrt{5} + 4 \sqrt{5}$

$= 3 \sqrt{5} - 6 \sqrt{5} + 4 \sqrt{5}$

$= 7 \sqrt{5} - 6 \sqrt{5}$

$= \sqrt{5}$

$2. \: \frac{ \sqrt{24} }{8} + \frac{ \sqrt{54} }{9}$

$\sf \colorbox{pink} {Answer. 2}$

$\textbf{Given:} \frac{ \sqrt{24} }{8} + \frac{ \sqrt{54} }{9}$

SOLUTION:

$= \frac{ \sqrt{24} }{8} + \frac{ \sqrt{54} }{9}$

$= \frac{ \sqrt{2 \times 2 \times 2 \times 3} }{8} + \frac{ \sqrt{2 \times 3 \times 3} }{9}$

$⇒ \frac{2 \sqrt{2 \times 3} }{8} + \frac{3 \sqrt{2 \times 3} }{9} = \frac{ \sqrt{6} }{4} + \frac{ \sqrt{6} }{3}$

$⇒ \sqrt{6} \left( \frac{1}{4} + \frac{1}{3} \right) \] = \sqrt{6} \times \frac{7}{12}$

$= \frac{7}{12} \sqrt{6}$

$3. \: \: \sqrt{3} - 2 \sqrt{27} + \frac{7}{ \sqrt{3} }$

$\sf \colorbox{pink} {Answer. 3}$

$\textbf{Given:} \sqrt{3} - 2 \sqrt{27} + \frac{7}{ \sqrt{3} }$

Solution:

$⇒3 \sqrt{3} - 2 \sqrt{27} + \frac{7}{ \sqrt{3} }$

$⇒3 \sqrt{3 } - 6 \sqrt{3} + \frac{7}{ \sqrt{3} }$

$⇒9 \sqrt{3} - \frac{7}{ \sqrt{3} } = \left( \frac{9 \sqrt{3} }{ \sqrt{3} } \times \sqrt{3} \right) \] + \frac{7}{3}$

$⇒ \frac{27}{ \sqrt{3} } + \frac{7}{ \sqrt{3} } = \frac{34}{ \sqrt{3} }$

$4. \: \sqrt[4]{81} - 8 \sqrt[3]{216} + 15 \sqrt[5]{32} + \sqrt{225}$

$\sf \colorbox{pink} {Answer .4 }$

$\textbf{Given:} \sqrt[4]{81} - 8 \sqrt[3]{216} + 15 \sqrt[5]{32} + \sqrt{225}$

Solution:

$= \sqrt[4]{ {3}^{4} } - 8$

$= \sqrt[3]{ {6}^{3} } + 15$

$= \sqrt[5]{ {2}^{5} } + \sqrt{ {15}^{2} }$

$= 3 - 8 \times 6 + 15 \times 2 + 15$
