Fina area of a triangle whose sides are 6cm, 8cm, 10cm,​

Answer»

Answer:

24cm2

Step-by-step EXPLANATION:

The AREA of a triangle with sides of length 6 cm , 8 cm and 10 cm has to be determined.

Looking at the length of the sides NOTICE that 6^2 + 8^2 = 36 + 64 = 100 = 10^2. This is a RIGHT triangle with perpendicular sides of length 6 and 8 cm. The area of the triangle is (1/2)*6*8 = 24 cm^2.

The area can also be derived using Heron's theorem. The area is given by sqrt(s*(s - a)*(s -B)*(s-c)) where s is the semi-perimeter equal to (6+8+10)/2 = 12 , a = 6, b = 8 and c = 10.

The area of the triangle is equal to sqrt(12*6*4*2) = sqrt(576) = 24 cm^2.

Answer»

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

GIVEN determinant is TO PROVE

\rm \: \begin{gathered}\sf \left | \begin{array}{ccc}y + z&<klux>X</klux> + y&x\\z + x&y + z& y\\x + y& z + x& z\end{array}\right | \end{gathered} = {x}^{3} + {y}^{3} + {z}^{3} - 3xyz

Consider LHS

\rm \: = \: \: \: \begin{gathered}\sf \left | \begin{array}{ccc}y + z&x + y&x\\z + x&y + z& y\\x + y& z + x& z\end{array}\right | \end{gathered}

\boxed{ \rm{ OP \: R_1 \: \longmapsto \: R_1 + R_2 + R_3}}

\rm \: = \: \: \: \begin{gathered}\sf \left | \begin{array}{ccc}2(x + y + z)&2(x + y + z)&x + y + z\\z + x&y + z& y\\x + y& z + x& z\end{array}\right | \end{gathered}

Take out x + y + z COMMON from Row 1, we get

\rm \: = \: (x + y + z)\begin{gathered}\sf \left | \begin{array}{ccc}2&2&1\\z + x&y + z& y\\x + y& z + x& z\end{array}\right | \end{gathered}

\boxed{ \rm{ OP \: C_1 \: \longmapsto \: C_1 - 2C_3}}

\rm \: = \: (x + y + z)\begin{gathered}\sf \left | \begin{array}{ccc}0&2&1\\z + x - 2y&y + z& y\\x + y - 2z& z + x& z\end{array}\right | \end{gathered}

\boxed{ \rm{ OP \: C_2 \: \longmapsto \: C_2 - 2C_3}}

\rm \: = \: (x + y + z)\begin{gathered}\sf \left | \begin{array}{ccc}0&0&1\\z + x - 2y&z - y& y\\x + y - 2z& x - z& z\end{array}\right | \end{gathered}

On expanding along Row 1, we get

\rm \: = \: (x + y + z)\bigg((z + x - 2y)(x - z) - (x + y - 2z)(z - y)\bigg)

\rm \:=(x + y + z)\bigg( {x}^{2} - {z}^{2} - 2xy + 2yz - xz + xy - yz + {y}^{2} + {2z}^{2} - 2yz\bigg)

\rm \:=(x + y + z)\bigg( {x}^{2} + {y}^{2} + {z}^{2} - xy - yz - zx \bigg)

\rm \: = \: \: {x}^{3} + {y}^{3} + {z}^{3} - 3xyz

Hence,

\rm \: \begin{gathered}\sf \left | \begin{array}{ccc}y + z&x + y&x\\z + x&y + z& y\\x + y& z + x& z\end{array}\right | \end{gathered} = {x}^{3} + {y}^{3} + {z}^{3} - 3xyz

Additional Information :-

1. The determinant VALUE remains unaltered if rows and columns are interchanged.

2. The determinant value is 0, if two rows or columns are identical.

3. The determinant value is multiplied by - 1, if successive rows or columns are interchanged.

4. The determinant value remains unaltered if rows or columns are added or subtracted.

A Contractor contracts to build a house in 30 days.He employed 20 mans to complete the house. After 20 days, they completed only 1/3 of the total of the total work how many more men will be required to finish the remaining work within the due time?

Answer»

Answer:a contractor GOT a contract to build a building in 30 days and employed 20 men to do the WORK. only 1/4 work was completed in 10 days. how many more men be employed so that the work be completed in the specified time?

:

Find the number of man-hrs to complete 1/4 of the job

20 * 10 = 200 man-days

therefore

3 * 200 = 600 man-days required to complete the job (For a total of 800 man-days)

:

Let m, = no. of additional men required to complete the job in the remaining 20 days

20(m + 20) = 600

20m + 400 = 600

20m = 600 - 400

20m = 200

m = 200/20

m = 10 additional men required to finish the job in the required 30 days

a cup is in the shape of frustum of a cone of height 6 cm.The radii of its two circular bases are 2 cm and 1 cm then the maximum water that be stored in the glass is​

Answer»

Given:

A cup is in the shape of a frustum of a cone of height 6 cm.The radii of its two circular bases are 2 cm and 1 cm then the maximum water that is stored in the glass is​?

To find:

The maximum water that is stored in the glass

Solution:

The dimensions of the cup in the shape of a frustum of a cone:

The height, h = 6 cm

The radius of the upper BASE, R = 2 cm

The radius of the LOWER base, r = 1 cm

We know,

\boxed{\bold{<klux>VOLUME</klux>\:of\:a\:frustum = \frac{1}{3} \times \<klux>PI</klux>\times h \times [R^2 + Rr + r^2]}}

Now,

The maximum quantity of water that can be stored in the glass is,

= Volume of the frustum

= \frac{1}{3} \times \frac{22}{7} \times 6 \times [2^2 + (2\times 1) + 1^2]}}

= \frac{22}{7} \times 2 \times [4 + 2 +1]}}

= \frac{22}{7} \times 2 \times 7

= 22\times 2

= 44\:cm^3

\boxed{\bold{1 \:cm^3 = 1 \:ml}}

= \bold{44\:ml}

Thus, the maximum water that can be stored in the glass is​ → 44 ml.

If the product of the zeroes of the quadratic polynomial 3x² + 5x + k is -2/3 , thenk = -3k = -2 k = 2k = 3

Answer»

Answer:

K = -2

Step-by-step explanation:

Given :

The product of the zeroes of the quadratic polynomial 3x² + 5x + k is -2/3

To find :

the value of k

Solution :

3x² + 5x + k

  • x² coefficient = 3
  • x coefficient = 5
  • CONSTANT term = k

From the relation between zeroes and coefficients of the quadratic equation :

Product of zeroes = constant term/x² coefficient  

 \sf \dfrac{-2}{3}=\dfrac{k}{3} \\\\ \sf k=\dfrac{-2}{3} \times 3 \\\\ \sf k=-2

THEREFORE, the value of k is -2
