Answer»

ANSWER:

RS.[1600×(1+2×1005)2+1600×(1+2×1005)]

=Rs.[1600×4041×4041+1600×6041]

=Rs.[1600×4041(4041+1)]

=Rs.[40×401600×41×81]

=Rs.3321.

∴C.I.=Rs.(3321−3200)=Rs.121

25. Find the value(s) of k so that the equations x² - 11x + k = 0 and x² - 14x + 2k = 0 may havea common root.⚠️ No spam ⚠️

Answer»

$\large\underline{\sf{Solution-}}$

Given quadratic equations are

$\rm :\longmapsto\: {x}^{2} - 11x + k = 0 - - (1)$

and

$\rm :\longmapsto\: {x}^{2} - 14x + 2k = 0 - - - (2)$

Let assume that 'y' be the common root.

Thus,

y must satisfy equation (1) and equation (2),

$\rm :\longmapsto\: {y}^{2} - 11y + k = 0 - - (3)$

and

$\rm :\longmapsto\: {y}^{2} - 14y + 2k = 0 - - - (4)$

Now,

Subtracting equation (4) from equation (3), we get

$3y - k = 0$

$\bf\implies \: y= \dfrac{k}{3} - - - (5)$

Now

Substituting the value of y in equation (3), we get

$\rm :\longmapsto\: {\bigg(\dfrac{k}{3} \bigg) }^{2} - 11\bigg(\dfrac{k}{3} \bigg) + k = 0 - - (3)$

$\rm :\longmapsto\:\dfrac{ {k}^{2} }{9} - \dfrac{11k}{3} + k = 0$

$\rm :\longmapsto\:\dfrac{ {k}^{2} - 33k + 9k}{9} = 0$

$\rm :\longmapsto\:\dfrac{ {k}^{2} -24k}{9} = 0$

$\rm :\longmapsto\:k(k - 24) = 0$

$\bf\implies \:k = 0 \: \: \: \: or \: \: \: \: 24$

$\begin{gathered}\begin{gathered}\bf\: \rm :\longmapsto\:Hence-\begin{cases} &\bf{k = 0} \\ &\bf{k = 24} \end{cases}\end{gathered}\end{gathered}$

Justification :-

Case :- 1

When k = 0,

The TWO equations reduces to

$\rm :\longmapsto\: {x}^{2} - 11x = 0$

$\rm :\longmapsto\: {x}(x - 11) = 0$

$\bf\implies \:x = 0 \: \: or \: \: 11$

and

$\rm :\longmapsto\: {x}^{2} - 14x = 0$

$\rm :\longmapsto\:x(x - 14) = 0$

$\bf\implies \:x = 0 \: \: or \: \: 14$

Hence,

$\red{ \boxed{ \sf{ \: 0 \: is \: the \: common \: root}}}$

Case :- 2

When k = 24

The two equations reduces to

$\rm :\longmapsto\: {x}^{2} - 11x + 24 = 0$

$\rm :\longmapsto\:(x - 8)(x - 3) = 0$

$\bf\implies \:x = 8 \: \: or \: \: 3$

and

$\rm :\longmapsto\: {x}^{2} - 14x + 48 = 0$

$\rm :\longmapsto\:(x - 8)(x - 6) = 0$

$\bf\implies \:x = 8 \: \: or \: \: 6$

Hence,

$\red{ \boxed{ \sf{ \: 8 \: is \: the \: common \: root}}}$

Additional Information :-

Nature of ROOTS :-

Let us consider a quadratic equation ax² + bx + c = 0, then nature of roots of quadratic equation DEPENDS upon Discriminant (D) of the quadratic equation.

If Discriminant, D > 0, then roots of the equation are real and unequal.

If Discriminant, D = 0, then roots of the equation are real and equal.

If Discriminant, D < 0, then roots of the equation are unreal or COMPLEX or imaginary.

Where,

Discriminant, D = b² - 4ac

Find the possible Length and Breadth of the rectangle, perimeter and the Length of the diagonal...(diagonal has 2 values in root)Area = 25a² - 35a + 12

Answer»

✰Solution :

$\:$

☞︎︎︎ Given :

$\:$

Area = 25a² - 35a + 12

$\:$

★ We KNOW ,

$\:$

➪ Area = Lenghth + breadth

$\:$

★ Area = 25a² - 35a + 12

$\:$

Splitting The Middle Term :

$\:$

= 25a² - 35a + 12

➪ 25a² - 20A - 15A + 12

➪ 5a(5a - 4) - 3(5a - 4)

= (5a - 3)(5a - 4)

= L × B

$\:$

☞︎︎︎ We have :

$\:$

Length = 5a - 3

$\:$

Breadth = 5a - 4

$\:$

✰ Perimeter = 2(lenght + breadth)

$\:$

➪ 2(5a - 3 + 5a - 4)

➪ 2(10a - 7)

➪ 2(10a) - 2(7)

➪ 20a - 14

$\:$

∴ perimeter = 20a - 14

$\:$

Finding Diagonal :

$\:$

☞︎︎︎ we get right ANGEL triangle by half of rectangle (diagonal)

$\:$

Pythagoras Theorem :

$\:$

✰ H² = B² + P²

$\:$

H = To find (diagonal)

B = 5a - 3

P = 5a - 4

$\:$

➪ H² = (5a - 3)² + (5a - 4)²

➪ H² = 25a² - 9 + 25a² - 16

➪ H² = 50a² - 25

then, Increase salary = 105% of x

Rs2205 = 105% of x

Rs2205 = 105/100 of x

Rs2205 × 100/105= x

Answer»

Steps to check WHETHER they can form a triangle :

Use triangle inequality theorm :

ADD the two smaller measurements of sides.

According to triangle inequality theorm, The SUM of the two smaller sides is greater than the third side.

If the sum of the smaller sides is not greater then the third side it cannot form a triangle.

If the sum of the smaller sides is greater then the third side it can form a triangle.

Then, We will get our answer.

Let's do the GIVEN questions now -

a) 6,8,12

b) 5,9,3

c) 11,6,6

d) 80,15,60

e) 8,6,10

f) 6,6,6

Now, As we see -

a) 6,8,12

Here, The smaller sides are - 6 & 8

$\implies \sf 6 + 8$

$\implies \sf 14$

$\sf \implies12 < 14$

∴ Hence, 6,8,12 will form a triangle.

b) 5,9,3

Here, The smaller sides are - 5 & 3.

$\implies \sf 5 + 3$

$\implies \sf 8$

$\sf \implies 9 > 8$

∴ Hence, 5,9,3 will not form a triangle.

c) 11,6,6

Here, The smaller sides are - 6 & 6.

$\implies \sf 6 + 6$

$\implies \sf 12$

$\sf \implies11< 12$

∴ Hence, 11,6,6 will form a triangle.

d) 80,15,60

Here, The smaller sides are - 15 & 60.

$\implies \sf 15 + 60$

$\implies \sf 75$

$\implies \sf 80 > 75$

∴ Hence, 80,15,60 will not form a triangle.

e) 8,6,10

Here, The smaller sides are - 6 & 8.

$\implies \sf 6 + 8$

$\implies \sf 14$

$\implies \sf 10 < 14$

∴ Hence, 8,6,10 will form a triangle.

f) 6,6,6

Here, The smaller sides are - 6 & 6.

$\implies \sf 6 + 6$

$\implies \sf 12$

$\implies \sf 6 < 12$

∴ Hence, 6,6,6 will form a triangle.

Answer»

Answer:

Insufficient amount. She requires 32.5 rs more to give 500 rs to her SISTER

Step-by-step explanation:

Given that daily wage of mesna is 85 rs

For HALF DAY the wage will be 85/2=42.5 rs

She worked for 5 days and a half day

So total wage will be = 5 *85 +42.5

=467.5Rs

She can't give 500rs to her sister because of insufficient FUND with her. So she need 32.5rs to give 500 rs to her sister

GIVEN : 500 रुपयांवरील द.सा.द.शे. 10% चक्रवाढव्याजदराने

To Find : 2 वर्षांचे चक्रवाढव्याज व 3 वर्षांचे चक्रवाढव्याज यातील फरक

SOLUTION:

P = 500

R = 10 %

N = 2 and 3

A = P (1 + R/100)ⁿ

n = 2

A = 500 ( 1 + 10/100)²

= 500 ( 11/10)²

= 5 * 121

= 605

n = 3

A = 500 ( 1 + 10/100)³

= 500 ( 11/10)³

= 5 * 121 * 11/10

= 665.5

665.5 - 605 = ₹60.50

2 वर्षांचे चक्रवाढव्याज व 3 वर्षांचे चक्रवाढव्याज यातील फरक = ₹60.50

Answer»

Step by Step Explanation

Step 1:

Start by setting it up with the DIVISOR 7 on the left side and the dividend 196 on the right side like this:

7 ⟌ 1 9 6

Step 2:

The divisor (7) goes into the first digit of the dividend (1), 0 time(s). Therefore, put 0 on top:

0

7 ⟌ 1 9 6

Step 3:

MULTIPLY the divisor by the result in the previous step (7 x 0 = 0) and write that ANSWER below the dividend.

0

7 ⟌ 1 9 6

Step 4:

Subtract the result in the previous step from the first digit of the dividend (1 - 0 = 1) and write the answer below.

Step 5:

Move down the 2nd digit of the dividend (9) like this:

0

7 ⟌ 1 9 6

ANSWER:

L.H.S. =p↔q

=(p→q)∧(q→p)

=(p∨∼q)∧(q∨∼p)

=((p∨∼q)∧q)∨((p∨∼q)∧∼p)

Answer» Let ABC be a RIGHT angled ∆ right angled at B. \_B = 90° \_A = 34° (GIVEN) By ANGLE sum property of ∆s, \_C = 180° - (90° + 34° ) = 180° - 124° \_C = 56°

In a right angle triangle one of the acute angles measure 34 find the measure of each angle of triangle

Answer»

Let ABC be a RIGHT angled ∆ right angled at B.

\_B = 90°

\_A = 34° (GIVEN)

By ANGLE sum property of ∆s,

\_C = 180° - (90° + 34° )

= 180° - 124°

\_C = 56°
