The sum and product of the zeroes of a quadratic polynomial are 3 and -10 respectively the quadratic polynomial is

Answer»

\large{\underline{\bf{\red{Given:-}}}}

  • ✦ sum of zeroes = 3
  • ✦ product of zeroes = -10

\large{\underline{\bf{\red{To\:Find:-}}}}

\huge{\underline{\bf{\green{Solution:-}}}}

LET α and β be the zeroes of the REQUIRED polynomial p(x).

Then

  • (α + β) = 3
  • αβ = -10

So,

p(x) = x² -(α + β)x + αβ

➝ p(x) = x² - 3x -10

So, the required polynomial is x² - 3x -10.

Verification:-

Sum of zeroes:-

(α + β) = - b/a

➝ 3 = -(-3)/1

➝ 3 = 3

Product of zeroes:-

αβ = c/a

➝ -10 = -10/1

➝ -10 = -10

LHS = RHS

hence, verified

5. Find the area of triangle formed by (3,5), (-3, -5) and (5,9)?​

Answer»

Answer:

√569

Step-by-step explanation:

По формуле Герона S= √p (p−a) (p−b) (p−c) ,  где  

полупериметр  p= 1/2 *(a+b+c).

А(3,5),В (-3, -5) С(5,9). Найдем длины сторон  по формуле  

d=√( (х₁-х₂)²+(у₁-у₂)²),  где (х₁;у₁),  (х₂;у₂) -координаты концов отрезка.

АВ=√( (-3-3)²+(-5-5) ²)=√136=2√34 это с,

ВС=√( (5+3)²+(9+5) ²)=√260=2√65 это а,

АС=√( (5-3)²+(9-5) ²)=√8=2√2 это в.

Найдем полупериметр

p= 1/2*(2√34+2√65+2√2),  

                                  р= √34+√65+√2.

р-а=√34+√65+√2-2√65=√34+√2-√65 ,

р-в=√34+√65+√2-2√2=√34+√65-√2 ,

р-с=√34+√65+√2-2√34=√65+√2-√34 ,

p (p−a) (p−b) (p−c)=  

=(√34+√65+√2)( √34+√2-√65)( √34+√65-√2 )( √65+√2-√34 )=

=((√34+√65) ²-√2²)(√2-(√65-√34)) ( √2+(√65-√34) )=

=((√34+√65) ²-√2²)(√2 ²-(√65-√34) ²)=

=(34+2√34*65 +65-2)(2 -(65-2√65*34+34) )=

=(97+2√34*65 )(2√65*34-97)=

=(2√34*65+97 )(2√65*34-97)=

=((2√34*65) ²-97 ² )=(4*34*65-9409)=569

S= √p (p−a) (p−b) (p−c)= √569

On a2. Points A and B are 70 km apart from each othershighway. A.com starts from n and anotherfrom B at the Sange time. they toravel in samedirection they meet in 7 hours, but if theytəravel towards each other, they meet in 1 hour.Find the speed of the two cars...​

Answer»

Step-by-step explanation:

When they travel in same direction, suppose

they meet when B travels for x m, then A will have travelled 70+x

m in the same time

Since, SPEED =

Time

Distance

Speed of car at A =

7

x+70

And Speed of car at B =

7

x

And when they travel in the opposite direction, suppose they meet when A

travels for y m, then B will have travelled 70−y m in the same

time

Speed of car at A =

1

y

=y

And Speed of car at B =

1

70−y

=70−y

Equating the speeds of the cars in both the cases,

Speed of car at A,

7

x+70

=y

x+70=7y

=>x−7y=−70 --- (1)

Speed of car at B,

7

x

=70−y

=>x+7y=490 --- (2)

Adding equations 1 and 2, we GET 2x=420=>x=210

So, Speed of car at A =

7

x+70

=

7

280

=40km/hr

Speed of car at B =

7

x

=

7

210

=30km/hr

49x - 57y = 172; 57x - 49y = 252​

Answer»

Answer:

49x - 57Y = 172

57x - 49y = 252

49x = 172 + 57y

x = 172+57y/48 ....................(1)

57 * 172+57y / 48 - 49y = 252

19*172+57y/16 -49y =252

3268+1083y/16 -49y = 252

3268+1083y - 784y/16=252

3268+299y = 252 * 16

3268 + 299y = 4032

299y = 4032-3268

299y= 764

y = 764/299

y= 2.5

put VALUE of y in EQUATION (1)

x= 172 + 57(2.5)/48

x= 146

Calculate the Body Mass Index of height 157 cm and weight 52 kg​

Answer»

Given:

Height - 157cm and WEIGHT - 52kg

To find:

BMI or Body Mass Index

Solution:

BMI = weight (kg)/height^2 (m)

157 cm = x m

100cm = 1m

x = 157/100

x = 1.57 m

BMI = 52/1.57^2

= 52/2.4649

= 21.09 which means a healthy person.

Extra Information:

1. BMI is a measurement of a person's health by using height and weight of a particular person.

2. The below one is the CHART for the result of the BMI

Category - BMI range - kg/m2
