6.	A dentist uses a mirror in front of a decayed tooth at a distance of 6 cm from the tooth to get a four times magnified image.
Answer» Answer: object distance, u = -4 cm magnification, m= 4 we know, m = -V/u ⇒ v = -mu ⇒ v = -(4)(-4) = 16 cm so image distance= 16 cm now, by mirror formula , 1/v + 1/u = 1/f ⇒ 1/16 + 1/-4 = 1/f ⇒ (1-4)/16 = 1/f ⇒ 1/f = -3/16 ∴ focal length = - 5.33 cm only a CONCAVE mirror can FORM magnified images. since, the image is FORMED behind the mirror, it is virtual and erect Step-by-step explanation:

6.

A dentist uses a mirror in front of a decayed tooth at a distance of 6 cm from the tooth to get a four times magnified image.

Answer»

Answer:

object distance, u = -4 cm

magnification, m= 4

we know, m = -V/u ⇒ v = -mu ⇒ v = -(4)(-4) = 16 cm

so image distance= 16 cm

now, by mirror formula ,

1/v + 1/u = 1/f

⇒ 1/16 + 1/-4 = 1/f

⇒ (1-4)/16 = 1/f

⇒ 1/f = -3/16

∴ focal length = - 5.33 cm

only a CONCAVE mirror can FORM magnified images.

since, the image is FORMED behind the mirror, it is virtual and erect

7.

3.127bar in p/q form

Answer»

Step-by-step explanation:

p/q = 3.127.... _(i)

multiply both SIDE by 100

p/q×100 = 3.127.. ×100

100p/q = 312.77.. _(II)

multiply equation (i) by 1000

p/q×1000 = 3.127.. ×1000

1000p/q = 3127.77... _(III)

subtract equation (ii) from (iii)

1000p/q-100p/q = 3127.77.. - 312.77...

900p/q = 2815

p/q = 2815/900

p/q = 563/180

Answer» <P> $\large\underline{\sf{Solution-}}$ Given polynomial is $\rm :\longmapsto\:p(x) = {ax}^{3} + 7x - 6$ It is given that, ONE ZERO of polynomial p(x) is 2. By factor theorem, $\rm :\longmapsto\:p(2) = 0$ $\rm :\longmapsto\:a {(2)}^{3} + 7 \times 2 - 6 = 0$ $\rm :\longmapsto\:8a + 14 - 6 = 0$ $\rm :\longmapsto\:8a + 8= 0$ $\rm :\longmapsto\:8a = - \: 8$ $\bf\implies \:a = - 1$ Thus, given polynomial p(x) can be REWRITTEN as $\rm :\longmapsto\:p(x) = { - x}^{3} + 7x - 6$ $\rm \: \: = \: - ( {x}^{3} - 7x + 6)$ $\rm \: \: = \: - ( {x}^{3} - x - 6x+ 6)$ $\rm \: \: = - \: \bigg(x( {x}^{2} - 1) - 6(x - 1) \bigg)$ $\rm \: \: = \: - \bigg(x(x - 1)(x + 1) - 6(x - 1) \bigg)$ $\rm \: \: = \: - (x - 1)\bigg(x(x + 1) - 6\bigg)$ $\rm \: \: = \: - (x - 1)\bigg( {x}^{2} + x - 6\bigg)$ $\rm \: \: = \: - (x - 1)\bigg( {x}^{2} + 3x - 2x - 6\bigg)$ $\rm \: \: = \: - (x - 1)\bigg(x(x + 3) - 2(x + 3)\bigg)$ $\rm \: \: = \: - (x - 1)(x + 3)(x - 2)$ $\bf\implies \:p(x) = \: - \: (x - 1)(x + 3)(x - 2)$ Hence, $\bf :\longmapsto\:Zeroes \: of \: p(x) = 1, - 3, 2$ So, Other zeroes are 1 and - 3

33.

If one zero of the polynomial ax³ + 7x-6 is 2, find the value of a and other zeros.Please answer step by step

Answer»

<P>

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

Given polynomial is

$\rm :\longmapsto\:p(x) = {ax}^{3} + 7x - 6$

It is given that, ONE ZERO of polynomial p(x) is 2.

By factor theorem,

$\rm :\longmapsto\:p(2) = 0$

$\rm :\longmapsto\:a {(2)}^{3} + 7 \times 2 - 6 = 0$

$\rm :\longmapsto\:8a + 14 - 6 = 0$

$\rm :\longmapsto\:8a + 8= 0$

$\rm :\longmapsto\:8a = - \: 8$

$\bf\implies \:a = - 1$

Thus, given polynomial p(x) can be REWRITTEN as

$\rm :\longmapsto\:p(x) = { - x}^{3} + 7x - 6$

$\rm \: \: = \: - ( {x}^{3} - 7x + 6)$

$\rm \: \: = \: - ( {x}^{3} - x - 6x+ 6)$

$\rm \: \: = - \: \bigg(x( {x}^{2} - 1) - 6(x - 1) \bigg)$

$\rm \: \: = \: - \bigg(x(x - 1)(x + 1) - 6(x - 1) \bigg)$

$\rm \: \: = \: - (x - 1)\bigg(x(x + 1) - 6\bigg)$

$\rm \: \: = \: - (x - 1)\bigg( {x}^{2} + x - 6\bigg)$

$\rm \: \: = \: - (x - 1)\bigg( {x}^{2} + 3x - 2x - 6\bigg)$

$\rm \: \: = \: - (x - 1)\bigg(x(x + 3) - 2(x + 3)\bigg)$

$\rm \: \: = \: - (x - 1)(x + 3)(x - 2)$

$\bf\implies \:p(x) = \: - \: (x - 1)(x + 3)(x - 2)$

Hence,

$\bf :\longmapsto\:Zeroes \: of \: p(x) = 1, - 3, 2$

So,

Other zeroes are 1 and - 3
