21.	Find the range of the function fx=
Answer» $\large\underline{\bold{Given \:Question - }}$ $\sf \: Find \: the \: range \: of \: the \: function \: f(x) = \dfrac{ {x}^{2} + 2x + <klux>1</klux>}{ {x}^{2} - 8x + 12 }$ $\large\underline{\bold{Solution-}}$ Following steps for used finding the range of a function are: Write down y = f(x) and then SOLVE the equation for x, giving something of the FORM x = g(y). Find the domain of g(y), and this will be the range of f(x). Note :- If you can't seem to solve for x, then try graphing the function to find the range. Now, Let's solve the problem now!! STEP :- 1 $\sf \: Let \: f(x) = y \: = \: \dfrac{ {x}^{2} + 2x + 1}{ {x}^{2} - 8x + 12 }$ $\sf \: {yx}^{2} - 8xy + 12y = {x}^{2} + 2x + 1$ $\sf \: {yx}^{2} - 8xy + 12y - {x}^{2} - 2x - 1 = 0$ $\sf \: (y - 1) {x}^{2} - x(8y + 2) + 12y - 1 = 0$ Step :- 2 Discriminant of the above QUADRATIC expression is $\sf \: Discriminant, D = {b}^{2} - 4ac$ $\sf \: D = {(8y + 2)}^{2} - 4(y - 1)(12y - 1)$ $\sf \: = 4 {(4y + 1)}^{2} - 4( {12y}^{2} - y - 12y + 1)$ $\sf \: = 4\bigg( {16y}^{2} + 1 + 8y - 12 {y}^{2} + 13y - 1 \bigg)$ $\sf \: =4( {4y}^{2} + 21y)$ Now, solution of above quadratic equation is given by $\rm :\longmapsto\:\sf \: x \: = \: \dfrac{ - b \: \pm \: \sqrt{ {b}^{2} - 4ac} }{2a}$ $\rm :\longmapsto\:x = \dfrac{8y + 2 \: \pm \: \sqrt{4y(4y + 21)} }{2(y - 1)}$ $\rm :\longmapsto\:x = \dfrac{4y + 1 \: \pm \: \sqrt{y(4y + 21)} }{(y - 1)}$ $\rm :\longmapsto\:y(4y + 21) \geqslant 0$ $\bf\implies \:y \leqslant - \dfrac{21}{4} \: \: \: or \: \: \: y \geqslant 0$

21.

Find the range of the function fx=

Answer»

$\large\underline{\bold{Given \:Question - }}$

$\sf \: Find \: the \: range \: of \: the \: function \: f(x) = \dfrac{ {x}^{2} + 2x + <klux>1</klux>}{ {x}^{2} - 8x + 12 }$

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

Following steps for used finding the range of a function are:

Write down y = f(x) and then SOLVE the equation for x, giving something of the FORM x = g(y).

Find the domain of g(y), and this will be the range of f(x).

Note :-

If you can't seem to solve for x, then try graphing the function to find the range.

Now, Let's solve the problem now!!

STEP :- 1

$\sf \: Let \: f(x) = y \: = \: \dfrac{ {x}^{2} + 2x + 1}{ {x}^{2} - 8x + 12 }$

$\sf \: {yx}^{2} - 8xy + 12y = {x}^{2} + 2x + 1$

$\sf \: {yx}^{2} - 8xy + 12y - {x}^{2} - 2x - 1 = 0$

$\sf \: (y - 1) {x}^{2} - x(8y + 2) + 12y - 1 = 0$

Step :- 2

Discriminant of the above QUADRATIC expression is

$\sf \: Discriminant, D = {b}^{2} - 4ac$

$\sf \: D = {(8y + 2)}^{2} - 4(y - 1)(12y - 1)$

$\sf \: = 4 {(4y + 1)}^{2} - 4( {12y}^{2} - y - 12y + 1)$

$\sf \: = 4\bigg( {16y}^{2} + 1 + 8y - 12 {y}^{2} + 13y - 1 \bigg)$

$\sf \: =4( {4y}^{2} + 21y)$

Now, solution of above quadratic equation is given by

$\rm :\longmapsto\:\sf \: x \: = \: \dfrac{ - b \: \pm \: \sqrt{ {b}^{2} - 4ac} }{2a}$

$\rm :\longmapsto\:x = \dfrac{8y + 2 \: \pm \: \sqrt{4y(4y + 21)} }{2(y - 1)}$

$\rm :\longmapsto\:x = \dfrac{4y + 1 \: \pm \: \sqrt{y(4y + 21)} }{(y - 1)}$

$\rm :\longmapsto\:y(4y + 21) \geqslant 0$

$\bf\implies \:y \leqslant - \dfrac{21}{4} \: \: \: or \: \: \: y \geqslant 0$

29.	In the given fig POQ is the diameter of the circle and
Answer» Given :- A C(O, r) such that POQ is a diameter and ∠POR = 110° To Find :- Value of ∠QSR Concept Used :- 1. Linear Pair :- Linear pair of angles are formed when two lines INTERSECT each other at a single point. The angles are said to be linear if they are adjacent to each other after the intersection of the two lines. The sum of angles of a linear pair is always equal to 180° 2. The ANGLE subtended by an arc at the centre is TWICE the angle subtended at the circumference. Solution :- Given that, ∠POR = 180°. As POQ is a line. ⇛ ∠POR + ∠QOR = 180° ⇛ 110° + ∠QOR = 180° ⇛ ∠QOR = 180° - 110° = 70°. Now, We know, The angle subtended by an arc at the centre is twice the angle subtended at the circumference Since, ∠QOR is subtened at the centre O and ∠QSR is subtended on the circumference of a circle by same arc RQ. Therefore, ⇛ ∠ROQ = 2 × ∠QSR ⇛ 2 × ∠QSR = 70° ⇛ ∠QSR = 35° ADDITIONAL INFORMATION :- Two equal chords of a circle subtend equal angles at the centre of the circle. If two angles subtended at the center by two chords are equal, then the chords are of equal length. The perpendicular to a chord bisects the chord if drawn from the centre of the circle. A straight line passing through the centre of a circle to bisect a chord is perpendicular to the chord. Equal chords of a circle are equidistant (equal distance) from the centre of the circle. The opposite angles in a cyclic quadrilateral are supplementary Angle in same segments are equal.

In the given fig POQ is the diameter of the circle and

Answer»

Given :-

A C(O, r) such that POQ is a diameter and ∠POR = 110°

To Find :-

Value of ∠QSR

Concept Used :-

1. Linear Pair :- Linear pair of angles are formed when two lines INTERSECT each other at a single point. The angles are said to be linear if they are adjacent to each other after the intersection of the two lines. The sum of angles of a linear pair is always equal to 180°

2. The ANGLE subtended by an arc at the centre is TWICE the angle subtended at the circumference.

Solution :-

Given that,

∠POR = 180°.

As POQ is a line.

⇛ ∠POR + ∠QOR = 180°

⇛ 110° + ∠QOR = 180°

⇛ ∠QOR = 180° - 110° = 70°.

Now,

We know, The angle subtended by an arc at the centre is twice the angle subtended at the circumference

Since, ∠QOR is subtened at the centre O and ∠QSR is subtended on the circumference of a circle by same arc RQ.

Therefore,

⇛ ∠ROQ = 2 × ∠QSR

⇛ 2 × ∠QSR = 70°

⇛ ∠QSR = 35°

ADDITIONAL INFORMATION :-

Two equal chords of a circle subtend equal angles at the centre of the circle.

If two angles subtended at the center by two chords are equal, then the chords are of equal length.

The perpendicular to a chord bisects the chord if drawn from the centre of the circle.

A straight line passing through the centre of a circle to bisect a chord is perpendicular to the chord.

Equal chords of a circle are equidistant (equal distance) from the centre of the circle.

The opposite angles in a cyclic quadrilateral are supplementary

Angle in same segments are equal.

LET it be the nth term of AP, where d = 6 - 5 = 1. ⇒ aₙ = a + (n - 1)d [formula] ⇒ 20 = 5 + (n - 1)(1) ⇒ 20 - 5 = n - 1 ⇒ 15 = n - 1 ⇒ 15 + 1 = n = 16 Thus, the position of the term WHOSE square is 400 in 16th, in the AP.

Consider Arithmetic sequence 5,6,7...Find the position of the term whose square is 400

Answer»

Answer:

16th position

Step-by-step explanation:

400 is the square on 20. Hence, we are asked for the TERM which is 20.

LET it be the nth term of AP, where d = 6 - 5 = 1.

⇒ aₙ = a + (n - 1)d [formula]

⇒ 20 = 5 + (n - 1)(1)

⇒ 20 - 5 = n - 1

⇒ 15 = n - 1

⇒ 15 + 1 = n = 16

Thus, the position of the term WHOSE square is 400 in 16th, in the AP.
