Here's your ANSWER ⭐⭐⚡

Here's your ANSWER......

T11 = 43

=> a + 10d = 43 -------(1)

T17 = 2× T8 + 5

=> a + 16d = 2 (a + 7d) + 5

=> a + 16d = 2a + 14D + 5

=> - a + 2d = 5

=> 2d - a = 5 -------(2)

On adding equation 1 and 2, we get

12d = 48

=> d = 4

Now,

On SUBSTITUTING the value d in equation 2, we get

2 (4) - a = 5

=> 8 - a = 5

=> a = 3

Tn = a + (n-1)d

= 3 + ( n-1)(4)

= 3 + 4N - 4

= 4n - 1

ANSWER is 62500%

Acc to the question, the population CONSISTS of five numbers 2 3 6 8 11.

Therefore,

Mean(µ) = = 6.0

Standard deviation(σ) = = 10.8

Mean of the sampling distribution = (sum of all samples)/25 = 150/25 = 6.0 [FORM a MATRIX of elements from the set of numnbers given and finally calculate its sum]

Standard deviation of the sampling distribution = subtract the mean 6

from each number, square the result, add all 25 numbers obtained, and divide by 25. = 135/25 = 5.4

@Neha

No, sum of two IRRATIONALS need but be IRRATIONAL always.
example: √2 and -√2 are irrationals
their sum: √2+(-√2)=√2-√2=0
zero is RATIONAL number.
hence, justified.

A+1/a=7
(a2+1)/a=7
a2-7a+1=0
find the VALUE of a by SOLVING above eqn.then SUBSTITUTE value of a in a3+1/a3

Answer:

Step-by-step explanation:

GIVEN that ;

Diagonals of a rhombus are 9 cm and 12 cm.

LET AC = 9 cm and BD = 12 cm

We KNOW that,

The diagonals of a rhombus bisect each other at right angles, i.e., 90°

Therefore,

AO = OC = 4.5 cm

BO = OD = 6 cm

Now, In ΔBOC,

BO = 8 cm

OC = 6 cm

∠BOC = 90°

Using Pythagoras theorem,

BC² = BO² + OC²

⇒ BC² = (4.5)² + 6²

⇒ BC² = 20.25 + 36

⇒ BC² = 56.25

⇒ BC = √56.25

⇒ BC = 7.5 cm

Also, we know that each side of rhombus is equal.

Hence, the length of each side of rhombus is 7.5 cm.

REARRANGING. =64a^3+48a^2-12a. DIVIDING EQUATION by 4A,. =16a^2+12a-3 =( 16a^2+12a) -3. =4a(4a+3)-3.

Answer: The coefficient of FRICTION would be 0.1. It is a dimensionless quantity.

Step-by-step EXPLANATION:

Given that

s=50 m

u=10 m/s

Now, using the third equation of MOTION, we get:

v^2-u^2=2as

Now, putting the values, we get:

0^2-10^2=2*a*50

-100=100a

a= -1

The negative sign of a SHOWS it is retardation.

Now,

F=ma

F=m*1=m

So, the frictional force is m kgms^(-2)

We know,

the formula of force of friction, F= kmg

where k=coefficient of friction, m= mass, and g= ACCELERATION due to gravity.

Now,

F=kmg

Putting the calculated value of F, we get:

m=km*10

k=0.1

Answer:

GIVEN EQUATION:

We have to FIND WHOSE solution is ALSO same as given equation.

Consider,

Solution is ,

GIVEN:

(1) ∫ (1+x)² / x(1+x²) dx

(2) ∫ (x^4+x^2+x) / 2(1+x²) dx

To find:

INTEGRATE the following.

Solution:

From given, we have,

(1) ∫ (1+x)² / x(1+x²) dx

taking the partial fraction, we get,

= ∫ 1/x + 2/(x²+1) dx

= ∫ 1/x dx + ∫ 2/(x²+1) dx

= log x + 2TAN^{-1}x + C

(2) ∫ (x^4+x^2+x) / 2(1+x²) dx

= 1/2 ∫ (x^4+x^2+x) / (1+x²) dx

using long division method, we get,

= 1/2 ∫ x² + 1/(1+x²) dx

= 1/2 [∫ x² dx + ∫ 1/(1+x²) dx]

= 1/2 [x³/3 + tan^{-1}x] + c

Dear friend,
Here's your answer...
Let the age of eldest be x.
Age of youngest = 36 yrs
Age of eldest = ?
Ratio of ages = 9 : 5
So, 36 / x = 9 / 5
180 = 9x
180 / 9 = x
20 = x
Therefore, the age of youngest is x = 20 years.
Hope it HELPS you!!

"GIVEN,

Area of two similar triangles = 12 cm², 48 cm².

Area of bigger triangle = 48 cm²

Area of smaller triangle = 12 cm²

We know that, Ratio of the areas of two similar is equal to square of the ratio of corresponding heights or ALTITUDES.

Given, HEIGHT of smaller triangle =2.1 CM.

Area (Bigger Triangle)/Area (Smaller Triangle) = (Height of bigger triangle) ^2/ (Height of smaller triangle) ^2

48/12 = (Height of bigger triangle) ^2/2.1²

4 = (Height of the triangle) ² / 4.41

√ (4 * 4.41) = Height of the bigger triangle

Height of the bigger triangle = 2 * 2.1 = 4.2 cm.

HEIGHT (H) = 5cm
area of its base (πr²) = 36π cm²
Where, r is the radius of it's base.

πr² = 36π

r² = 36

r = 6CM

Now,we have r = 6cm ,h = 5cm.

and C.s.a of cylinder = 2πrh

2πrh = 2 * π * 6 * 5

= 60π cm²

Hence, the curved surface area of the cylinder = 60π cm²

That can be WRITTEN as COS(a+b)+cos(a-b)..........ie...cos(60)+cos(30)........1/2+root 3/2.....so final ANSWER 1+root3 by 2

LET the two numbers be x and y

Given that, x + y = 16 and xy = 48

xy = 48, => x = 48 / y

Substituting x = 48 / y in the equation x + y = 16, we GET,

48 / y + y = 16

Taking LCM,

48 + y² / y = 16

48 + y² = 16 y

=> y² - 16y + 48 = 0

=> y² - 12 y - 4 y + 48 = 0

=> y ( y - 12 ) - 4 ( y - 12 ) = 0

=> ( y - 4 ) ( y - 12 ) = 0

=> y = 4, 12

If y = 4, then x = 48 / 4 = 12

If y = 12, then x = 48 / 12 = 4

Hence the two numbers just get INTERCHANGED in both cases. Hence the two numbers are 12 and 4.

Answer:

Step-by-step EXPLANATION:

Given that,

a+b-c = 5 and a^2+b^2+c^2 = 29

Using the formula

(a+b+c)^2 = a^2+b^2+c^2+2(ab+bc+ca)

=>(a+b+(-c)^2= a^2+b^2+c^2+2(ab+bc+ca)

=>(a+b-c)^2= a^2+b^2+c^2+2(ab-bc-ca)

=>5^2= 29+2(ab-bc-ca)

=>25= 29+2(ab-bc-ca)

=>ab-bc-ca= 25-29/2

=>ab-bc-ca= -4/2

=>ab-bc-ca= -2

Ans: -2

LET the angle be 'm'

Thus, its COMPLEMENT will be '8m'

We know that when two angles are Complementary, then there is sum is EQUAL to 90°

So,

→ m + 8m = 90°

→ 9M = 90°

→ m = 10° & 8m = 80°

Therefore, the angles are 10° and 80°.
