Soumya Ghoshal 8 years, 3 months ago

If we write,{tex}3=\frac{{30}}{10}{/tex}

and {tex}4= \frac{{40}}{10}{/tex}

Then, we can easily find the number between them. Which are,

{tex}\frac{{31}}{10},\frac{{32}}{10},\frac{{33}}{10},\frac{{35}}{10},\frac{{36}}{10},\frac{{38}}{10}{/tex}

Let a,b,c be the sides of the triangle. Perimeter 2s = a + b + c

Semi-perimeter, s ={tex} a+b+c\over 2{/tex}

Using Heron's formula: Area of the triangle A = {tex}\sqrt {s(s−a)(s−b)(s−c) }{/tex}

Now, if the sides are doubled: 2a, 2b, 2c Let s' be the semi-perimeter.

2s' = 2a + 2b + 2c

s' = a + b + c or s' = 2s

Area of the triangle,

A' = {tex}\sqrt {s′(s′−2a)(s′−2b)(s′−2c) }{/tex}

A' = {tex} \sqrt {(2s)(2s−2a)(2s−2b)(2s−2c)}{/tex}

A'= {tex}\sqrt {16s(s−a)(s−b)(s−c) }{/tex}

A' ={tex} 4\sqrt {s(s−a)(s−b)(s−c) }{/tex}

A' = 4A

A':A = 4:1

Ratio of area of the new triangle and old triangle is 4:1

Third side of given triangle = 240 - (78 + 50) = 240 - 128 = 112 dm

Semiperimeter of triangle (s) = {tex}{{240} \over 2}{/tex} = 120 dm

Now, Area of triangle = {tex}\sqrt {s\left( {s - a} \right)\left( {s - b} \right)\left( {s - c} \right)} {/tex}

{tex}\sqrt {120\left( {120 - 78} \right)\left( {120 - 50} \right)\left( {120 - 112} \right)} {/tex}

{tex}\sqrt {120 \times 42 \times 70 \times 8} {/tex}

{tex}\sqrt {10 \times 10 \times 7 \times 7 \times 6 \times 6 \times 4 \times 4} {/tex}

= 10 x 7 x 6 x 4 

= 1680 sq. dm

Now, again Area of triangle = {tex}{1 \over 2}{/tex}x Base x Height (Perpendicular)

=>     1680 = {tex}{1 \over 2}{/tex}x 50 x Perpendicular

=>     Perpendicular = {tex}{{1680 \times 2} \over {50}}{/tex}

=>     Perpendicular = 67.2 dm

{tex}a + b = {a \over b} + {b \over a}{/tex}

=>    {tex}a + b = {{{a^2} + {b^2}} \over {ab}}{/tex}

=>     {tex}{a^2} + {b^2} = ab\left( {a + b} \right){/tex}

Hans Raj 8 years, 3 months ago

a + b = a/b + b/a

squaring both sides

a2  + b2 + 2ab = a2/b2 + b2/a2 + 2

a2 + b2 = a2/b2 + b2/a2 + 2 - 2ab

{tex}a+b=\frac{{a}}{b}+\frac{{b}}{a}{/tex}

or, {tex}a+b=\frac{{a^2+b^2}}{ab}{/tex}

or, {tex}ab(a+b)=a^2+b^2{/tex}

or, {tex}a^2+b^2=a^2b+ab^2{/tex}

If (x - 1) is a factor of p(x), then

p(1) = 0

=>     12 + 1 + k = 0

=>     1 + 1 + k = 0

=>     2 + k = 0

=>    k = -2
