What is the value of k for which 2x2-kx+k=0 has equal roots?​

Answer»

Answer:

Hello Mate . Wassup

Step-by-step explanation:

The values of k = 4.

Given:

Quadratic equation 2x^{2}+Kx +2=02x

2

+Kx+2=0 has equal ROOTS.

To find:

The values of k

Explanation:

General format of quadratic equation is ax^2+bx+c =0ax

2

+bx+c=0 .

If the roots of quadratic equation is equal then,

\sqrt{B^{2} \ -\ 4ac }=0

b

2

− 4ac

=0

Where,

a = coefficient of x²

b = coefficient of x

c = constant term.

\sqrt{b^{2} \ -\ 4ac }=0

b

2

− 4ac

=0

b² - 4ac =0

Comparing the quadratic equation

2x^{2}+Kx +2=02x

2

+Kx+2=0

b = k a=2 c=2

k² - 4×2×2 = 0

k² = 16

k = \sqrt{16}

16

k = 4

3 The sum of two opposite angles of a quadrilateral is 172°. The other two angles of the quadrilateral areequal. Find the equal angles.​

Answer»

Given :

⬤ Sum of two Opposite angles of Quadrilateral is 172 degree .

To FIND :

⬤ Other two equal Angles .

Solution :

Let :

  • Two Equal Angles be x and x .

As we know that , Sum of all Angles of Quadrilateral is 360 degree . Hence ,

\sf{172+x+x=360^{\circ}}

172 + 2X = 360

2x = 360 - 162

2x = 188

x = 188/2

x = 94

Therefore , The Value of x is 94 .

Hence ,

One Angle = x

= 94

Second Angle = x

= 94

Check :

172 + 2(94) = 360°

172 + 188 = 360°

360° = 360°

Hence CHECKED .

Length , breadth and height of a rectangular cistern are 3 m , 2 m and 1m respectively. Maximum amount of water that can be contained in the cistern is :​

Answer»

Answer :-

  • Max. amount of water in cistern = 6000 L

GIVEN :-

  • Length of Cistern = 3 m
  • WIDTH of Cistern = 2 m
  • Height of Cistern = 1 m

To FIND :-

  • Max. amount of water in cistern = ?

Explanation :-

As above given, we have Length, Width & Height of the Cistern.

The cistern will be filled with water, it MEANS we need to find the volume of the cistern.

\blue { \boxed { \bf \bigstar \: Volume \: of \: Cistern = Length \times Width \times Height \: \bigstar}}

\sf : \: \longmapsto L \times W \times H = Volume \: of \: Cistern

\sf : \: \longmapsto (3 \times 2 \times 1) \: m^3

\sf : \: \longmapsto (6 \times 1) \: m^3

\green { \underline { \boxed { \sf : \: \longmapsto \bold{6 \: m^3} \quad \star }}}

Now we will find the Max. Amount of water that cistern can contain

\sf We \: Know \: That,

\sf : \: \longmapsto 1 \: m^3 = \bold{1000 \: Litres}

\sf : \: \longmapsto 6 \: m^3 = (6 \times 1000) \: Litres

\purple { \underline { \boxed { \bf = 6000 \: Litres}}}

Hence, the Maximum capacity or Amount of water that cistern can contained is 6000 L.

4. Calculate the actual C.P. and then find out if there is a profit or loss in the following.a. C.P ₹140overhead charges ₹20Actual C.P ?S.P ₹200profit and loss ? ​

Answer»

Answer:

LOSS: If the SELLING price is less than the cost price, the difference between them is the loss incurred.

Formula: Loss = Cost price (C.P.) – Selling Price (S.P.)

Profit or Loss is always calculated on the cost price.

MARKED price: This is the price marked as the selling price on an article, also known as the listed price.

Discount or Rebate: This is the reduction in price offered on the marked or listed price.

Below is the list of some basic formulas used in solving questions on profit and loss:

Gain % = (Gain / CP) * 100

Loss % = (Loss / CP) * 100

SP = [(100 + Gain%) / 100] * CP

SP = [(100 – Loss %) / 100]*CP

The above two formulas can be stated as,

If an article is sold at a gain of 10%, then SP = 110% of CP.

If an article is sold at a loss of 10%, then SP = 90% of CP.

CP = [100 / (100 + Gain%)] * SP

CP = [100 / (100 – Loss%)] * SP

Profit and Loss: Solved Examples

Question 1: An article is purchased for Rs. 450 and sold for Rs. 500. Find the gain percent.

Solution:

Gain = SP – CP = 500 – 450 = 50.

Gain% = (50/450)*100 = 100/9 %
