18301.

Find the tenth term AP (√8,√18, √32)

Answer»

Answer

The 10TH TERM of the given AP is 10√2 or √200

$\bf \large \underline{Given : }$

The AP is

√8 , √18 , √32

$\bf \large \underline{To \: Find : }$

The 10th term of the AP

$\bf \large \underline{Solution : }$

Given , the AP is

➝ √8 , √18 , √32

➝ 2√2 , 3√2 , 4√2

Therefore ,

FIRST term , a = 2√2

and COMMON difference,

» d = 3√2 - 2√2

» d = √2

We know that ,

$\longrightarrow \: \: \rm a _{n} = a + (n - 1)d \\ \\ \implies \rm a_{10} = 2 \sqrt{2} + (10 - 1) \sqrt{2} \\ \\ \rm \implies a_{10} = 2\sqrt{2} + 9 \sqrt{2} \\ \\ \rm\implies a_{10} = 10 \sqrt{2}$

Therefore, the 10th term of the AP is 10√2 or √200

18312.

The Numerator is 9less than thedenominator.if 2 is subtracted from both numeratorand denominator , fraction becomes 2/5.find the fraction.دام

Answer»

Answer:

Let fraction be= x/y.

1 st case

Numerator is 9 less than the DENOMINATOR.

∴x=y-9..........................(1)

2nd case

if 2 is subtracted from both numerator and denominator , fraction becomes 2/5.

∴(x-2)/(y-2)=2/5.

Cross multiply the above equation:

5(x-2)=2(y-2)

5x-10=2y-4

5x=2y-4+10

5x=2y+6.

Take 2 as common.

5x=2(y+3)

5x/2=y+3.......................(2)

Subtract 1 and 2.

5x/2=y+3

x=y-9

3x/2=12

3x=12×2

x=24/3

x=8.

Now, ADD 1 and 2.

you will get y=17.

fraction:x/y=8/17.

Thus, required fraction is 8/17.

Prove that √sec2θ + cosec2θ = tan θ + cot θ .

Answer»

TO PROVE :–

$\\ \implies { \bold{ \sqrt{ { \sec}^{2} \theta + {cosec}^{2} \theta } = \tan( \theta) + \cot( \theta) }} \\$

SOLUTION :–

• Let's TAKE L.H.S. –

$\\ \: \: = \: \: { \bold{ \sqrt{ { \sec}^{2} \theta + {cosec}^{2} \theta }}} \\$

▪︎ Using identity –

$\\ \: \: \dashrightarrow\: \: { \bold{ { \sec}^{2} \theta = 1 + { \tan}^{2} \theta}} \\$

$\\ \: \: \dashrightarrow\: \: { \bold{ { cosec}^{2} \theta = 1 + { \cot}^{2} \theta}} \\$

• So that –

$\\ \: \: = \: \: { \bold{ \sqrt{1 + { \tan}^{2} \theta+1 + { \cot}^{2} \theta}}} \\$

$\\ \: \: = \: \: { \bold{ \sqrt{ { \tan}^{2} \theta+2+ { \cot}^{2} \theta}}} \\$

• We should WRITE this as –

$\\ \: \: = \: \: { \bold{ \sqrt{ { \tan}^{2} \theta+2 \tan \theta \cot \theta + { \cot}^{2} \theta}}} \\$

• Using identity –

$\\ \: \: \dashrightarrow\: \: { \bold{ {a}^{2} + 2ab + {b}^{2} = {(a + b)}^{2} }} \\$

$\\ \: \: = \: \: { \bold{ \sqrt{{( \tan \theta + \cot \theta )}^{2}}}} \\$

$\\ \: \: = \: \: { \bold{ \tan \theta + \cot \theta }} \\$

$\\ \: \: = \: \: { \bold{R.H.S. }} \\$

$\\ \: \: \: \: \: { \underbrace{ \bold{Hence \: \: proved }}} \\$

18315.	If α and 1/ α are the zeroes of the polynomial 4 – 2x + (k – 4 )find the value of k.
Answer» QUESTION : If α and 1/ α are the zeroes of the polynomial 4x² – 2x + (k – 4 ) , find the value of k . Answér : k = 8 Note: ★ The possible values of the VARIABLE for which the polynomial BECOMES zero are called its zeros . ★ A quadratic polynomial can have atmost two zeros . ★ The general form of a quadratic polynomial is given as ; ax² + bx + c . ★ If α and ß are the zeros of the quadratic polynomial ax² + bx + c , then ; • Sum of zeros , (α + ß) = -b/a • Product of zeros , (αß) = c/a Solution : The given quadratic polynomial is ; 4x² - 2x + (k - 4) . Comparing the given quadratic polynomial with the general quadratic polynomial ax² + bx + c , we have ; a = 4 b = -2 c = k - 4 Also , It is given that , α and 1/α are the zeros of the given quadratic polynomial . Thus , => Product of zeros = c/a => α × (1/α) = (k - 4)/4 => 1 = (k - 4)/4 => 1 × 4 = k - 4 => 4 = k - 4 => 4 + 4 = k => 8 = k => k = 8 Hence , Required value of k is 8 .

If α and 1/ α are the zeroes of the polynomial 4 – 2x + (k – 4 )find the value of k.

Answer»

QUESTION :

If α and 1/ α are the zeroes of the polynomial 4x² – 2x + (k – 4 ) , find the value of k .

Answér :

k = 8

Note:

★ The possible values of the VARIABLE for which the polynomial BECOMES zero are called its zeros .

★ A quadratic polynomial can have atmost two zeros .

★ The general form of a quadratic polynomial is given as ; ax² + bx + c .

★ If α and ß are the zeros of the quadratic polynomial ax² + bx + c , then ;

• Sum of zeros , (α + ß) = -b/a

• Product of zeros , (αß) = c/a

Solution :

The given quadratic polynomial is ;

4x² - 2x + (k - 4) .

Comparing the given quadratic polynomial with the general quadratic polynomial ax² + bx + c , we have ;

a = 4

b = -2

c = k - 4

Also ,

It is given that , α and 1/α are the zeros of the given quadratic polynomial .

Thus ,

=> Product of zeros = c/a

=> α × (1/α) = (k - 4)/4

=> 1 = (k - 4)/4

=> 1 × 4 = k - 4

=> 4 = k - 4

=> 4 + 4 = k

=> 8 = k

=> k = 8

Hence ,

Required value of k is 8 .

Find the 30th term of the AP 10,7,4........In this question, can you expline how we get the common difference.?

Answer»

Answer:

-77 (COMMON difference means the difference between 2 consecutive terms or constant)

Step-by-step explanation:

LET a be the first term

n be the no. of terms

d be the difference

The formula for A.P. = a + (n - 1)d

a = 10

n = 30

d = -3(as it is descending)

a + (n - 1)d

10 + (30 - 1)*(-3)

10 + (-87)

10 - 87

-77

Conclusion

∴ the 30th term is -77

Hope you UNDERSTOOD :)
