Answer»

Step-by-step EXPLANATION:

a+1/a=6

Squaring both SIDES, we GET,

$a^{2}$ +1/ $a^{2}$ +(2*a*1/a)=36

$a^{2}$ +1/ $a^{2}$ +2=36

So,

$a^{2}$ +1/ $a^{2}$ =34

Further, I hope you can SOLVE it yourself.

27.

Find the ratio in which y-axis divides theline segment joining the points A(5, -6) andB(-1,-4). Also find the co-ordinates of the pointof division.

Answer»

Step-by-step explanation:

Let the ratio in which the line segment joining A (1, - 5) and B ( - 4, 5) is divided by x-axis be K: 1

Therefore, the coordinates of the point of division is (-4k+1/k+1,5k-5/k+1)

We know that y-coordinate of any point on x-axis is 0

Therefore,

(5k-5/k+1)= 0

k = 1

Therefore, x-axis DIVIDES it in the ratio 1:1.

Division point = ()

= (-4(1)+1/1+1,5(1)-5/1+1)

= (-3/2, 0)

if alpha and beeta are the zero of the polynomial p(x)=3x2--12x++15 find the value of alpha square ++beeta square

Answer»

Solution :

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

If α and β are the ZEROES of the polynomial p(x) = 3x² - 12X + 15.

$\bf{\green{\underline{\underline{\bf{To\:find\::}}}}}$

The value of α² + β².

$\bf{\green{\underline{\underline{\bf{Explanation\::}}}}}$

We have quadratic polynomial as we compared with ax² + bx + c = 0;

a = 3
b = -12
c = 15

$\bf{\orange{\underline{\underline{\mathcal{SUM\:OF\:THE\:ZEROES\::}}}}}$

$\mapsto\sf{\alpha +\beta =\dfrac{-b}{a} =\dfrac{Coefficient\:of\:(x)^{2} }{Coefficient\:of\:x} }\\\\\\\mapsto\sf{\alpha +\beta =\dfrac{-(-12)}{3} }\\\\\\\mapsto\sf{\alpha +\beta =\cancel{\dfrac{12}{3}} }\\\\\\\mapsto\sf{\red{\alpha +\beta =4}}$

$\bf{\orange{\underline{\underline{\mathcal{PRODUCT\:OF\:THE\:ZEROES\::}}}}}$

$\mapsto\sf{\alpha \times \beta =\dfrac{c}{a} =\dfrac{Constant\:term }{Coefficient\:of\:x} }\\\\\\\mapsto\sf{\alpha \times \beta =\dfrac{15}{3} }\\\\\\\mapsto\sf{\alpha \times \beta =\cancel{\dfrac{15}{3}} }\\\\\\\mapsto\sf{\red{\alpha \times \beta =5}}$

Now;

$\mapsto\sf{\alpha^{2} +\beta ^{2} =(\alpha +\beta)^{2} -2\alpha \beta }\\\\\mapsto\sf{\alpha^{2} +\beta^{2} =(4 )^{2} -2(5) }\\\\\mapsto\sf{\alpha^{2} +\beta^{2} =16 -10}\\\\\mapsto\alpha^{2} +\beta ^{2}=16-10}\\ \\\mapsto\sf{\orange{\alpha^{2}+ \beta ^{2} =6}}$

44.	the radius and height of a cylinder are equal . find the total surface area if its curved surfacearea is 628cm2. π =3.14
Answer» ANSWER: the answer is 1256 $cm^{2}$ first we should find the radius and height through given information Step-by-step explanation: given that radius and height of CYLINDER are EQUAL radius =height (r=h) given CSA=628 $cm^{2}$ 2 $\pi$ rh=628 substitue in this formula then (2 $\pi$ r)x(r)=628 {r=h} if we complete eliminating we GET r=10cm so r=h=10cm now we should find Total surface area of the cylinder TSA =2 $\pi$ r(r+h) 2(3.14)(10)(10+10) 6.28(10)(20) 6.28(200) 1256 $cm^{2}$

the radius and height of a cylinder are equal . find the total surface area if its curved surfacearea is 628cm2. π =3.14

Answer»

ANSWER:

the answer is 1256 $cm^{2}$

first we should find the radius and height through given information

Step-by-step explanation:

given that radius and height of CYLINDER are EQUAL

radius =height (r=h)

given CSA=628 $cm^{2}$

2 $\pi$ rh=628

substitue in this formula then (2 $\pi$ r)x(r)=628 {r=h}

if we complete eliminating we GET r=10cm so r=h=10cm

now we should find Total surface area of the cylinder

TSA =2 $\pi$ r(r+h)

2(3.14)(10)(10+10)

6.28(10)(20)

6.28(200)

1256 $cm^{2}$
