For what values of k are the roots of kx^2+(k-1)x+(k-1) =0 equals

Answer»

For equal roots,

Discriminent = 0

=> b^2 - 4ac = 0

=> (K-1)^2 - 4(k-1)(k) = 0

=> (k-1)^2 = 4(k-1)(k)

=> k - 1 = 4k

=> - 3k = 1

=> k = - 1/3

Ask your questions help me

Answer»

1)

x/3 - 2/5 = x/5 + 5/6
x/3 - x/5 = 5/6 + 2/5
5x - 3x /5 = 25 + 12/30
2X/5 = 37/30
2x = 37*5/30
2x = 37/6 [ 5/30 = 1/6 ]
x = 37/6*2
x = 37/12

Show that x^2+x+1=0 has real roots

Answer»

X^2 + x + 1 = 0

On COMPARING given equation with general equation, we get

a = 1

b = 1

c = 1

Discriminent = b^2 - 4ac

= (1)^2 - 4(1)(1)

= 1 - 4

= - 3

Discriminent is negative.

So the given equation has no real roots.

Father said to daughter when i was in your age you were 4 years old but then you will be in my age i would be 79 years old then what is the present age of father and daughter

Answer»

LET the CURRENT AGE of the father be X and that of the daughter be Y.

When father was Y the daughter was 4 YEARS.

Their age DIFFERENCE is the same for all ages.

(Y - 4) years.

(X - Y) years

X - Y = Y - 4

-2Y = - 4 - X

2Y = X + 4

Y = 0.5X + 2

The current age of the daughter is : 0.5X + 2

Their age difference is :

X - 0.5X - 2 = 0.5X - 2

When the father is 79 the daughter is X

Their age difference is :

79 - X = 0.5 X - 2

81 = 1.5 X

X = 81/1.5

X = 54

The current age of the daughter is :

0.5 × 54 + 2 = 29

Present age of the :

Father : 54

Daughter : 29

Fid the sum all natural no less then 200 which are divisble 5

Answer»

A = 5

d = 5

L = 195

=> a + (n-1)d = 195

=> 5 + (n-1)(5) = 195

=> (n-1)(5) = 190

=> n - 1 = 38

=> n = 39

SN = 39/2 [ 5 + 195]

= (39)(200) /2

= 39 × 100

= 3900

Required sum = 3900

If a-b=3 and a^3-b^3=117, then what is a+ba)5 b)7 c)9 d)11

Answer»

A-B = 3
a=3+b
{x}^{3}  -  {y}^{3}  = (x - y)( {x}^{2}  +  {y}^{2}  + xy)
using this formula,

3((3+b^2)+b^2+3b+b^2) = 117
=3(3b^2+3b+3) =117
taking 9 common from both sides,
b^2+b+1=13
b^2+b-12=0
b^2+4b-3b-12=0
b(b+4)-3(b+4)=0
b = 3, -4
if b = 3
a = 6
=a+b = 9
if b = -4
a = -1
a+b = -5
answer is,
9 ..

Show that x^2+x+1=0 has no real roots

Answer»

We have equation...

X^2+x+1=0

or x^2 +2(x)(1/2) +1/4 - 1/4 +1=0

or (x+1/2)^2 -1/4 +4/4=0

or (x+1/2)^2+3/4=0
=> (x+1/2)^2=-3/4
=> x=+-√(-3/4) -1/2
It SHOWS that x is not REAL.

Two positive numbers X and Y are inversely proportional. if X increases by 20% then percentage decreases in y is a) 15 b) 16 2/3 c) 17 11/9 d) 25

Answer»

x is inversely proportional to y

⇒ x = k/y


Make y the SUBJECT:

x = k/y

xy = k

y = k/x


When x increases by 20%

⇒ x = 1.2x


Sub x = 1.2x into the equation:

y = k/1.2x


Find the increase in y:

increase = k/1.2x - k/x = k/6x


Find the PERCENTAGE increase:

Percentage increase =(k/6x ÷ k/x) x 100

Percentage increase = 16 2/3%


ANSWER: (b) 16 2/3%

Find six rational number between 5/6 and9/10? pls tell in easy way

Answer»

So , you want RATIONAL numbers between 5/6 and 9/10 then you have to make their denominators same firstly .

TAKE their LCM(Least Common Multiple) :
LCM of 6 and 10 is 30 .

5×5/6×5 = 25/30

9×3/10×3 = 27/30

But now there are not sufficient numbers between them multiply both by ten and there are many numbers after that .
25×10/30×10= 250/300
27×10/30×10 = 270/300 .

Hence 6 rational numbers between them are 251/300,252/300,253/300,254/300,255/300,256/300 .

Rational numbers are those numbers which are in the form of p/q where both p and q = integers and q ≠ 0 .

There are infinite rational numbers between two numbers .
