Class 10 quad equation question plz helppppppp

Answer» ERE, on comparing with general equation ax 2 + bx + => c = 0, we get

=> a = 1

=> b = - 3

=> c = - m(m + 3)

=> Now, Discriminant = D = (b² – 4AC)

∴ D = [9 -4 × (-m(m + 3))]

=> [9 + 4m2 + 12 m]

=> (2m + 3)2

=> Therefore roots of the equation are given by:

=> X = (-b ± √D)/2a

∴ x = (3 ± (2m + 3))/2

=> [(6 + 2m)/2] or [-2m/2]

=> 3 + m or – m.

=> Thus the roots of the equation are: - m and m + 3.

I hope this will help you DEAR..

Find variance and standard deviationof anyrondomvariable x​

Answer»

So the VARIANCE of X is the weighted average of the SQUARED deviations from the mean μ, where the weights are given by the probability FUNCTION pX(x) of X. The standard DEVIATION of X is defined to be the SQUARE root of the variance of X. That is, sd(X)=σX=√var(X).

Answer»

the C.P of spirit be = Rs.10 PER litre

Then S.P l litre of the MIXTURE = Rs. 11

Profit = 20%  

Therefore, C.P of the mixture = Rs. [100120×10] = Rs. 25/3 per litre

Therefore, Ratio of water and spirit = 1 : 5

2 24) The total surface area of a closed cylinder is 3872 cm If its radiusis 14cm, then find the height of the cylinder and the volume of thecylinder.​

Answer»

ong>Given:

To find:

  • Height & VOLUME of the cylinder?

SOLUTION:

• Let's consider ABCD is a cylinder.

Where,

  • Radius = 14m
  • TSA = 3872m

• Let Height of cylinder be h m.

⠀⠀━━━━━━━━━━━━━━━━━━━⠀

« Now, By using the formula,

→ 2πr (r + h) = 3872

→ 2 × 22/7 × 14(14 + h) = 3872

→ 2 × 22 × 2(14 + h) = 3872

→ 14 + h = 3872/88

→ 14 + h = 44

→ h = 44 - 14

→ h = 30cm

⠀⠀━━━━━━━━━━━━━━━━━━━⠀

« Now, Let's find volume,

As we know that,

→ Volume = πr²h

→ 22/7 × 14² × 30

22/7 × 196 × 30

→ 22 × 28 × 30

→ 18480cm³

∴ Hence, Volume of the cylinder is 18480cm³.

The ratio of corresponding sides of Simlartriagles is 3; 5 ; then findthe ration of their areas​

Answer»

ong>Answer:

ratio of their AREAS 9 : 25

Step-by-step EXPLANATION:

If two triangles are similar, then the ratio of the area of both triangles is proportional to the square of the ratio of their corresponding sides.

This proves that the ratio of the area of two similar triangles is proportional to the squares of the corresponding sides of both the triangles.

Area (∆ ABC) : area ( ∆ DEF) = AB² : DE²

3² : 5²

= 9 : 25

9x^2 - 27x + 14 = 0​

Answer»

ong>Answer:

1. Use Euclid’s division algorithm to find the HCF of:

i. 135 and 225

ii. 196 and 38220

iii. 867 and 225

Solutions:

i. 135 and 225

As you can see, from the question 225 is greater than 135. Therefore, by Euclid’s division algorithm, we have,

225 = 135 × 1 + 90

Now, remainder 90 ≠ 0, thus again using division lemma for 90, we get,

135 = 90 × 1 + 45

Again, 45 ≠ 0, repeating the above step for 45, we get,

90 = 45 × 2 + 0

The remainder is now ZERO, so our method stops here. Since, in the last step, the divisor is 45, therefore, HCF (225,135) = HCF (135, 90) = HCF (90, 45) = 45.

Hence, the HCF of 225 and 135 is 45.

ii. 196 and 38220

In this GIVEN question, 38220>196, therefore the by applying Euclid’s division algorithm and taking 38220 as divisor, we get,

38220 = 196 × 195 + 0

We have already got the remainder as 0 here. Therefore, HCF(196, 38220) = 196.

Hence, the HCF of 196 and 38220 is 196.

iii. 867 and 225

As we know, 867 is greater than 225. Let us apply now Euclid’s division algorithm on 867, to get,

867 = 225 × 3 + 102

Remainder 102 ≠ 0, therefore taking 225 as divisor and applying the division lemma method, we get,

225 = 102 × 2 + 51

Again, 51 ≠ 0. Now 102 is the new divisor, so repeating the same step we get,

102 = 51 × 2 + 0

The remainder is now zero, so our procedure stops here. Since, in the last step, the divisor is 51, therefore, HCF (867,225) = HCF(225,102) = HCF(102,51) = 51.

Hence, the HCF of 867 and 225 is 51.

present age of seema's mother is 5 time and 1 year more then seema .four year before product of thire ages are 22 then find thire present age​

Answer»

Basic Concept Used :-

Writing Systems of Linear Equations from WORD Problems

1. UNDERSTAND the problem.

  • Understand all the words used in stating the problem.

  • Understand what you are asked to find.

2. Translate the problem to an equation.

  • Assign a variable (or variables) to REPRESENT the unknown.

  • Clearly STATE what the variable represents.

3. Carry out the plan and solve the problem.

Let's solve the problem now!!

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

  • Let present age of Seema be 'x' years

So,

  • MOTHER's present age be 5x + 1 years

So, we have present ages of two as

\begin{gathered}\begin{gathered}\bf \:Age \:of-\begin{cases} &\sf{Seema  = x \: years} \\ &\sf{Mother \:  = 5x + 1 \: years} \end{cases}\end{gathered}\end{gathered}

Now,

  • 4 years ago, the ages are as follow :-

\begin{gathered}\begin{gathered}\bf \:Age \:of-\begin{cases} &\sf{Seema  = x  - 4\: years} \\ &\sf{Mother \:  = 5x + 1 - 4 = 5x - 3 \: years} \end{cases}\end{gathered}\end{gathered}

According to statement,

  • The product of their ages 4 years ago is 22.

\rm :\longmapsto\:(5x - 3)(x - 4) = 22

\rm :\longmapsto\: {5x}^{2} - 20x - 3x + 12 = 22

\rm :\longmapsto\: {5x}^{2} - 23x - 10 = 0

\rm :\longmapsto\: {5x}^{2}  - 25x  + 2x - 10 = 0

\rm :\longmapsto\:5x(x - 5) - 2(x - 5) = 0

\rm :\longmapsto\:(x - 5)(5x - 2) = 0

\rm :\implies\:x = 5 \:  \:  \: or \:  \:  \: x = \dfrac{2}{5}  \:  \{rejected \}

Hence,

\begin{gathered}\begin{gathered}\bf \:Age \:of-\begin{cases} &\sf{Seema  = x  = 5\: years} \\ &\sf{Mother \:  = 5x + 1  = 5 \times 5 + 1 = 26\: years} \end{cases}\end{gathered}\end{gathered}

22.

The sum of two number is 35 and them ratio is 1:4. find the number​

Answer» SOLUTION:-

━━━━━━━━━━━━━━━━━━━━━━━━━━

\large\to{\underbrace{\underline{\sf{Understanding\:the\:concept:-}}}}

\implies Here it is given in the question that the sum of two numbers is 35 and their ratio is 1:4. Now, the question has asked us to find out the the numbers. So, to find the numbers, assume the numbers as 1x and 4x. And after that follow the steps shown below.

ANSWER:-

1ST number = 7

⬤ 2nd number = 28

GIVEN:-

⟼ 1st number = 1x

⟼ 2nd number = 4x

TO FIND:-

⟿ Numbers = ?

HOW TO DO:-

➜ 1st number + 2nd number = Sum

SOLVING BY APPLYING THE FORMULA:-

⟼ 1st number = 1x

⟼ 2nd number = 4x

➜ 1st number + 2nd number = Sum

  • Finding the number:-

Sum is 35.

So,

➜ 1x + 4x = 35

Adding the terms:- 1x + 4x = 5x

So,

➜ 5x = 35

Taking 5 to R.H.S:- 35 / 5

So,

➜ x = 35 / 5

Remainder after DIVIDING the terms:- 35 / 5 = 7

So,

➜ x = 7

Final Answer:- 7

So,

➜ x = 7

  • Numbers:-

➜ 1st number = 1x

⠀⠀⠀⠀⠀1x = 1 × 7

⠀⠀⠀⠀⠀⠀⠀= 7

1st number is 7.

➜ 2nd = 4x

⠀⠀⠀⠀⠀⠀4x = 4 × 7

⠀⠀⠀⠀⠀⠀ ⠀= 28

2nd number is 28.

VERIFICATION:-

➜ 7 + 28

➜ 7 + 28 = 35

➜ 35

∴ L.H.S = R.H.S

Hence, verified.

Solve: ax + by = a - b and bx - ay = a + b Please send the photo of it​

Answer» ONG>Step-by-step explanation:

\huge\underline\mathcal{\red{Question:-}}

\impliesSOLVE: ax + by = a - b and bx - ay = a + b

Taking the LCM of the LEFT Hand SIDE we have;

\frac{ab -  {b}^{2}  -  {b}^{2}y -  {a}^{2} y }{a}  =  a  + b

Moving a to the RHS we have;

ab -  {b}^{2}  -  {b}^{2} y -  {a}^{2} y = a(a + b)

ab -  {b }^{2}  -  {b}^{2} y -  {a}^{2} y =  {a}^{2}  + ab

-  {b}^{2}  -  {b}^{2} y -  {a}^{2} y =  {a}^{2}  + ab - ab

-  {b}^{2}  -  {b}^{2} y -  {a}^{2} y =  {a}^{2}

Moving {-b}^{2} to the RHS and taking y common in the LHS we have;

- y( {b}^{2}  +  {a}^{2} ) =  {a}^{2}  +  {b}^{2}

- y = 1

y = -1

Now,

Putting the value of y in (3) We have;

x =  \frac{a - b - b( - 1)}{a}

x =  \frac{a - b + b}{a}

x =  \frac{a}{a}

x = 1
