Answer:First we draw a line with length of 10 cm let say AB = 10 cmThen divide it into half as take arc of more than half length of the line and place point at A and make two arc on both side of the line , Now do the same for poin B and both arc intersect At C and D As:

That gives us AE = EBNow we divide section AE and EB to get four equal parts of our line AB = 10 cmSo , place point at A and take arc of more than half of AE and make two arc on both side of the line , and do same for placing point at E , that gives two point F and G .Do above step for line segment EBand get two point H and I As:

Nowlength of all four sectionAJ = JE = EK = KB = 2.5 cm

hey gd aftrnhere is your answerGiven that alpha and beta are the roots of the quadratic equation f(x) = x^2-p(x+1)-c = x^2-px-p-c = x^2 -px-(p+c), comparing with ax^2 + bx + c, we have, a =1 , b= -p & c= -(p+c) alpha+beta = -b/a = -(-p)/1 = p & alpha*beta = c/a = -(p+c)/1 = -(p+c) Therefore, (Alpha + 1)*(beta+1) = Alpha*beta + alpha + beta + 1 = -(p+c) + p + 1 = -p-c+p+1 = 1-c or c=1hope its help you plz mark as brainlist answer and follow me for more brainlist answer thanxx and be brainly.................................

Correct question : If α and β are the zeros of the polynomial x² - p ( x + 1 ) + c such that, ( α + 1 ) ( β + 1 ) = 0 then find the value of c. Answer:

c = - 1

Step-by-step explanation:

x² - p ( x + 1 ) + c

⇒ x² - p x - p + c

⇒ x² - p x + ( c - p )

Comparing with ax² + bx + c, we get :

a = 1

b = - p

c = c - p .

Given :

( α + 1 )( β + 1 ) = 0

⇒ αβ + α + β + 1 = 0

Note that, sum of roots = - b/a

α + β = - b / a

But b = - p

a = 1

So α + β = - ( - p ) / 1 = p

Product of roots = αβ = c / a

⇒ αβ = ( c - p )

Hence write this as :

αβ + α + β + 1 = 0

⇒ c - p + p + 1 = 0

⇒ c + 1 = 0

⇒ c = -1

Hence, the value of c is - 1.

c is -1 is a correct answer.....

2/5 * (-3/7) - 1/6 * 3/2 + 1/14*2/5

= - 6/35 - 1/4 + 1/35

= (-6 + 1)/35 - 1/4

= - 5/35 - 1/4

= - 1/7 - 1/4

= (-4 - 7)/28

= - 11/28

-11/28 is the answer

-11/28 is the answer

U can use RHS congruence rule.In ∆ADB and ∆ADCangleADB=angleADC=90° (since AD is perpendicular to BC)

AB=AC( since it is an isos triangle)AND. AD=AD (common)therefore the triangles are congruent. BD=DC(by cpct)

distance = 12kmlet original velocity and time be v,t=> distance = velocity * timechanged velocity = v+1changed time = t-1v*t = 12 = ( v+1)*(t-1)=>t-v-1 = 0 => t-v = 1t+v = 5 by solving we get velocity = 2 kmph

the length and breadth of our school is hall is 2000 cm and 1600cm. Let's find the length of the longest tape which can measure both length and breadth in exact whole number

Length of school hall = 2000 cmBreadth of school hall = 1600 cm

The length of longest tape os equal to HCF of 2000 and 1600

Factors of 2000 = 2, 2, 2, 2, 5, 5, 5Factors of 1600 = 2, 2, 2, 2, 2, 2, 5, 5

HCF = 2*2*2*2*5*5 = 400

Therefore length of longest tape to measure length and breadth of hall= 400 cm

400 cm is the right answer

400 is the correct answer

Diagnols are hypotenuse.So length=(10^2 - 6^2)^(1/2)=(100-36)^(1/2)=64^(1/2)Length=8cm

3x - y = 3 .....(1)

9x - 3y = 9 ......(2)

From (1), y = 3x - 3

Put in (2)

9x - 3 ( 3x - 3) = 9

9x - 9x + 9 = 9

9 = 9

So, there are infinite solution.

thanks bhai

Thank u so mch

1.the teacher told/ordered the boys to sit properly and look at the diagram on the black board.2 My friend asked me why he was not read the book givan by him.

Height of cone, h = 8 cmRadius of cone, r = 2 cmLet radius of sphere be “R” cmSince cone is melted and made into a sphereVolume of sphere = Volume of cone(4/3)πR^3= (1/3)πr^2hThat is, 4R^3= r^2h4R^3= (2)^2x 8R^3= 8 = 2^3Therefore, R = 2Thus diameter of sphere is 4 cm.
