ANSWER:

X2-2kx+7k-12=0

A = 1 , B = -2k , C = 7k-12

d = b^2 - 4AC

= 4k^2 - 4 × 1 × 7k-12

= 4k^2 - 28K + 48=0

= k^2 - 7k + 12 = 0

= (k-4) (k-3) = 0

= k = 4 , k = 3

ANSWER:

Answer:

Let the sequence of 3n consecutive integers begin with m. Then

3n consecutive integers are

m,m+1,m+2,....m+(3n−1)

3 integers from 3n can be selected in

3n

C

WAYS

∴ Total no. of outcomes =

Now 3n integers can be divided into 3 groups

G

1

:n numbers of form 3p

G

2

:n numbers of form 3p+1

G

3

:n numbers of form 3p+2

The sum of 3 integers chosen from 3n integers will be DIVISIBLE by 3 if either all the three are from same group or one integer from each group. The no. of ways that the three integers are from same group is

Step-by-step explanation:

Given Let α1 be a circle with CENTRE O and AB be diameter. Let P be a point on OB different from O. Suppose another circle α2 with centre P lies in the INTERIOR of α1. Tangents are drawn from A and B to the circle α2 intersecting α1 at A1 and B1 RESPECTIVELY such that A1 and B1 are on opposite side of AB. If A1B = 6, AB1 = 18 and OP = 10, find radius of α1

• So there is a circle α1 with centre O and diameter AB. P is a point on OB a bit forward from O. Also another circle α2 with centre P is on the interior of α1.  
• Now A1 and B1 are on opposite side of AB.
•                  Let OP = b and AB = a
•       Now from the triangle APQ we have  
•                                     Sin theta = b/a + 10 ------1
•    From triangle AA1B we get
•                                      Sin theta = 6/2a ----------2
•            From 1 and 2 we get
•                              So b / a + 10 = 6/2a ------------3
•          Similarly we get
•                             So b / a – 10 = 18 / 2a -----------4
•                      6a + 60 = 18a – 180
•                      6a – 18 a = - 180 – 60
•                         Or – 12 a = - 240
•                         Or a = 240 / 12
•                           Or a = 20
• Therefore radius of α1 = 20

ANSWER:

None of these

PLEASE mark as BRAINLIEST answer and FOLLOW me please

Given :-

• First term (a) = -3

• Common difference (d) = -1/2 - (-3) = -1/2 + 3 = -1 + 6/2 = 5/2

• n = 11

To find :-

• 11th term of AP = ?

Solution :-

By USING formula of an,

we KNOW that,

Hence,the 11th term of AP will be 22,

More INFORMATION :-

Formula to find Sn :-

Sn = n/2 [2A + (n - 1)d]

AP :- A sequence in which each term differs from its preceding term by a constant is called an ARITHMETIC progression or AP.

• This Constant is called the common difference of the AP.

HOPE it will HELP you DEAR ☺️

Step-by-step explanation:

In parallelogram ABCD,

Angle A = Angle C .......(since opp. ANGLES of a llgm are equal) .....1

Similarly , Angle B = Angle D

Construct a diagnal BD

Now , angle ABD = angle BDC ...(diagnols bisect the angles of a llgm).....2

Side AD = side BC....(opp. sides of llgm are equal)..3

From 1, 2, 3

By ASA CONGRUENCY rule

triangle ABD = triangle BDC

Answer:

∫11+x4 dx

=∫1x21+x4x2 dx

=∫1x2x2+1x2 dx

=12∫2x2x2+1x2 dx

=12∫(1+1x2)−(1−1x2)x2+1x2 dx

=12∫(1+1x2)dxx2+1x2−12∫(1−1x2)dxx2+1x2

=12∫(1+1x2)dxx2+1x2−2+2−12∫(1−1x2)dxx2+1x2+2−2

=12∫d(x−1x)(x−1x)2+2−12∫d(x+1x)(x+1x)2−2

=12∫d(x−1x)(x−1x)2+(2√)2−12∫d(x+1x)(x+1x)2−(2√)2

★ Now, using STANDARD formula: ∫dxx2+a2=1atan−1(XA) & ∫dxx2−a2=12aln∣∣x−ax+a∣∣

=12⋅12√tan−1(x−1x2√)−12⋅122√ln∣∣∣x+1x−2√x+1x+2√∣∣∣+C

=122√tan−1(x2−1x2√)−142√ln∣∣x2−x2√+1x2+x2√+1∣∣+C

Answer:

R-I

Step-by-step explanation:

For F(X) to be defined the quantity inside the root must be >0

==> x - [x] >0

Then x>[x]

x = [x] + {x}

[x] + {x} >[x]

Or {x} >0

So 0<={x}<1

Therefore, 1/{x} is only defined when

{x} > 0 or x not in Integers, since if {x} = 0, x element of I

So Domain = R-I
