15902.

The quadratic equation ax^2-4ax+2a+1=0 has repeated root if a=?

Answer»

Step-by-step explanation:

Ax square - 4ax + 2a+1 = 0

by applying B square - 4AC = 0

(-4a) square - 4.a.(2a+1) =0

16a square - 4a ( 2a+1) =0

16a.a - 8a.a -4a =0

by taking 4a common

4a (2a-1) =0

(2a-1) = 0

a = 1/2 or

a = 0

15917.

For what value of m are the number x,2x+m and 3x+6 three consecutive terms

Answer»

If these three terms are consecutive, the difference between the first and second and second and third terms will be equal and difference between each TERM will be 1.

2x + m - X = 1

x + m = 1

x = 1 - m [email protected]

(2x + m) - (1) = (3x + 6) - (2x + m)

2x + m - 1 = 3x + 6 - 2x - m

2x + m - 1 = x - m + 6

2x - x + m + m = 6 + 1

x + 2m = 7

1 - m + 2m = 7 (From @)

m = 7 - 1

m = 6

15919.

Solve the simultaneous equations x − 2 y = 0 9 x + 2 y = 30 what is x what is y

Answer»

Answér :

x = 3 , y = 3/2

Solution :

Here ,

The given equations are ;

x - 2Y = 0 --------(1)

9x + 2y = 30 -----------(2)

Now ,

ADDING eq-(1) and (2) , we GET ;

=> x - 2y + 9x + 2y = 0 + 30

=> 10x = 30

=> x = 30/10

=> x = 3

Now ,

PUTTING x = 3 in eq-(1) , we get ;

=> x - 2y = 0

=> 3 - 2y = 0

=> 3 = 2y

=> 2y = 3

=> y = 3/2

Hence ,

x = 3 , y = 3/2

Answer:

Step-by-step explanation:

Let A = NUMBERS under 20 div by 3 = {3,6,9,12,15,18}

B = no's under 20 div by 4 => {4,8,12,20}

C = no's under 20 div by 5 = > {5,10,15,20}

intersection -> &

then (A&B) = 1, (B&C)=1, (A&C) = 1,(A&B&C) =0

15942.

The 7th term of an Ap is -1 and the 16th term is 17.FIND THE Nth TERM

Answer»

AnsWer :

- 13 , - 11 , - 9.....

SolutioN :

LET,

FIRST term be a
Common difference be d
an = a + ( N - 1 ) d.

Case 1

The 7th term of an Ap is - 1.

$\tt \dagger \: \: \: \: \: a_7 = - 1.$

Case 2.

$\tt \dagger \: \: \: \: \: a_{16} = 17$

Let's Find the nth terms.

$\tt \dagger \: \: \: \: \: \boxed{\tt a_n = a + (n - 1)d}$

Taking Case 1.

$\tt : \implies \tt a_7 = - 1.$

$\tt : \implies a + (7 - 1)d = - 1.$

$\tt : \implies a + 6d = - 1. \: \: \: \: \: - (1)$

Taking case 2.

$\tt : \implies a +(16 - 1)d = 17.$

$\tt : \implies a + 15d = 17. \: \: \: \: \: - (2)$

Subtraction, Equation ( 1 ) and ( 2 )

$\tt a + 15d = 17.$

$\tt a + 6d = - 1.$

________________________________

$\tt : \implies9d = 18.$

$\tt : \implies d = \dfrac{18}{9}$

$\tt : \implies d = 2.$

Now, PUTTING the value of d = 2. ( in Case 1 )

$\tt : \implies a + 6d = - 1.$

$\tt : \implies a + 6(2)= - 1.$

$\tt : \implies a +12 = - 1.$

$\tt : \implies a = - 1 - 12.$

$\tt : \implies a = - 13.$

$\rule{200}3$

Let find nth terms.

→ an = a + ( n - 1 )d.

n = 1 , 2 , 3...
a = - 13.
d = 2.

$\tt \dagger \: \: \: \: \: a_1 = a + (n - 1)d$

$\tt : \implies a_1 = - 13 + (1- 1)2$

$\tt : \implies a_1 = - 13 +0$

$\tt : \implies a_1 = - 13.$

$\rule{200}3$

$\tt : \implies a_2 = - 13 +(2 - 1)2$

$\tt : \implies a_2 = - 13 +2$

$\tt : \implies a_2 = - 11.$

$\rule{200}3$

$\tt : \implies a_3 = - 13 +(3- 1)2$

$\tt : \implies a_3= - 13 +4$

$\tt : \implies a_3 = -9.$

Therefore, the value of nth of AP , - 13 , - 11 , - 9 .... so on.

Answer»

Step-by-step EXPLANATION:

discount he OFFERS = 25%

cost price of IRON = RS 1600

selling price of iron = rs 1600 - (25/100 ×1600)

= rs1600 - rs400

= rs 1200
