1.	If f(x) = x*2-1, solve f (x+2)-f(x-2) -16
Answer» Step-by-step explanation: Given :- f(x) = x^2-1 To FIND:- Solve f(x+2) -f(x-2)-16 Answer:- Given that f(x) = x^2-1 => f(x+2) =(x+2)^2-1 We know that (a+b)^2 = a^2+2ab+b^2 => x^2+2(x)(2)+2^2-1 => x^2+4x+4-1 =>x^2+4x+3 f(x+2)=x^2+4x+3 and f(x-2) = (x-2)^2-1 We know that (a-b)^2=a^2-2ab+b^2 =>x^2-2(x)(2)+2^2-1 =>x^2-4x+4-1 =>x^2-4x+3 f(x-2) = x^2-4x+3 Now f(x+2) -f(x-2)-16 => (x^2+4x+3 )-(x^2-4x+3)-16 => x^2+4x+3-x^2+4x-3-16 => (x^2-x^2)+(4x+4x)+(3-3-16) =>0+8x+(-16) => 8x-16 Answer:- The value of f(x+2) -f(x-2)-16 for the given PROBLEM is 8x-16 Used FORMULAE:- (a+b)^2 = a^2+2ab+b^2 (a-b)^2=a^2-2ab+b^2

1.

If f(x) = x*2-1, solve f (x+2)-f(x-2) -16

Answer»

Step-by-step explanation:

Given :-

f(x) = x^2-1

To FIND:-

Solve f(x+2) -f(x-2)-16

Answer:-

Given that

f(x) = x^2-1

=> f(x+2) =(x+2)^2-1

We know that

(a+b)^2 = a^2+2ab+b^2

=> x^2+2(x)(2)+2^2-1

=> x^2+4x+4-1

=>x^2+4x+3

f(x+2)=x^2+4x+3

and

f(x-2) = (x-2)^2-1

We know that

(a-b)^2=a^2-2ab+b^2

=>x^2-2(x)(2)+2^2-1

=>x^2-4x+4-1

=>x^2-4x+3

f(x-2) = x^2-4x+3

Now

f(x+2) -f(x-2)-16

=> (x^2+4x+3 )-(x^2-4x+3)-16

=> x^2+4x+3-x^2+4x-3-16

=> (x^2-x^2)+(4x+4x)+(3-3-16)

=>0+8x+(-16)

=> 8x-16

Answer:-

The value of f(x+2) -f(x-2)-16 for the given PROBLEM is 8x-16

Used FORMULAE:-

(a+b)^2 = a^2+2ab+b^2

(a-b)^2=a^2-2ab+b^2

17x+23y=40 & 23x+17y=100 so x-y =?

Answer»

$\underline{\pink{\bf{Given}}}\\$

${ \sf17x + 23y = 40}\\$
${ \sf23x + 17y = 100}\\$

$\underline{\pink{\bf{To~Find}}}\\\\$

$\sf \: x - y\\$

$\\\underline{\pink{\bf{Solution}}}\\$

We have

$\\{ \sf17x + 23y = 40} \: \: \: \: \: - - - - (<klux>1</klux>)\\\\$

${ \sf23x + 17y = 100} \: \: \: \: \: - - - - (2)\\$

On SOLVING EQUATION 1 We GET,

$\\{ \implies\sf17x + 23y = 40}$

${ \implies\sf17x = 40 - 23y}$

${ \implies\sf x = \cfrac{ 40 - 23y}{17}}\\\\$

$\\\text{\orange{Putting the value of x in Equation 2 We get,}}$

$\\ { \implies\sf23 \left(\cfrac{ 40 - 23y}{17} \right) + 17y = 100}$

${ \implies\sf\cfrac{ (23 \times 40 )-(23 \times 23y)}{17} + 17y = 100}$

${ \implies\sf\cfrac{ 920 - 529y}{17} + 17y = 100}$

${ \implies\sf\cfrac{ 920 - 529y + 289y}{17} = 100}$

${ \implies\sf\cfrac{ 920 - 240y}{17} = 100}$

${ \implies\sf920 - 240y = 100 \times 17}$

${ \implies\sf- 240y =1700 - 920}$

${ \implies\sf- 240y =780}$

${ \implies\sf y = \cfrac{ \: \: \xcancel{780}^{3.25} }{ \xcancel{ - 240}}}$

${~~~~~~~ \green{\sf y = - 3.25}}\\\\$

$\text{\blue{Putting the value of Y in Equation 1 We get,}}\\\\$

${\implies \sf17x + 23y = 40}$

${ \implies\sf17x + 23 \times( - 3.25 )= 40}$

${\implies \sf17x - 74.55= 40}$

${ \implies\sf17x = 40 + 74.75}$

${\implies \sf x = \cfrac{40 + 74.75}{17}}$

${\implies \sf x = \cfrac{114.75}{17}}$

${ ~~~~~~~\orange{\sf x = 6.75}}\\\\$

$\implies\sf{Value \: of \: (x-y)= 6.75-(-3.25)}$

48.	The volume of a rectangular parallelopiped/cuboid of a square base is 144 CC and its diagonal of the base is 6 cm. Find the height of the parallelepiped/cuboid.
Answer» Answer: Step-by-step explanation: Assuming that the surface is the outer surface and the diagonal is top left front corner to right rear LOWER corner and the sides are a, b and c, then we have the following equations. [math]abc = 144[/math] [math]2ab + 2bc [/math][math]= 192[/math] or [math]2b(a + c) [/math][math]= 96[/math] [math]\sqrt{a^2 + b^2 + c^2} = 13 [/math] or [math] a^2 + b^2 +c^2 = 169[/math] These three equations can be solved simultaneously to find the answers, but it is also possible to use a spot of number analysis to break the answer out the above. The factors of 144 are [math]2^4 * 3^2[/math] so the three factors must use all of them between them. All dimensions must be less than 13, the INTERNAL diagonal, so list the numbers from 1 to 12 that can only be FORMED with these factors. They are: 1, 2, 3, 4, 6, 8, 9 and 12. The sides can only be of these possible lengths. Looking at equation 3 the sums of the squares add to an odd number. One of the numbers must be a 3 or a 9 for the square to be odd and the total odd, the other two are even. It is not possible to have three odd numbers. Were this odd number to be a 9 then the squares of the other two numbers have to add up to 169–81 = 88. After some study it is not possible to sum the squares of two of the above numbers to 88, so one of the sides is 3. So let's say b = 3. Having FOUND that the other two side multiply to 144/3 = 48. Out of the above list there are only two pairs of candidates 4 * 12 and 6 * 8. Looking at equation 2, then 6(a + b) equals 96. This rules out the 6 and 8. Therefore, the three sides are 3, 4, and 12

The volume of a rectangular parallelopiped/cuboid of a square base is 144 CC and its diagonal of the base is 6 cm. Find the height of the parallelepiped/cuboid.

Answer»

Answer:

Step-by-step explanation:

Assuming that the surface is the outer surface and the diagonal is top left front corner to right rear LOWER corner and the sides are a, b and c, then we have the following equations.

[math]abc = 144[/math]

[math]2ab + 2bc [/math][math]= 192[/math] or [math]2b(a + c) [/math][math]= 96[/math]

[math]\sqrt{a^2 + b^2 + c^2} = 13 [/math] or [math] a^2 + b^2 +c^2 = 169[/math]

These three equations can be solved simultaneously to find the answers, but it is also possible to use a spot of number analysis to break the answer out the above.

The factors of 144 are [math]2^4 * 3^2[/math] so the three factors must use all of them between them.

All dimensions must be less than 13, the INTERNAL diagonal, so list the numbers from 1 to 12 that can only be FORMED with these factors. They are:

1, 2, 3, 4, 6, 8, 9 and 12. The sides can only be of these possible lengths.

Looking at equation 3 the sums of the squares add to an odd number. One of the numbers must be a 3 or a 9 for the square to be odd and the total odd, the other two are even. It is not possible to have three odd numbers. Were this odd number to be a 9 then the squares of the other two numbers have to add up to 169–81 = 88. After some study it is not possible to sum the squares of two of the above numbers to 88, so one of the sides is 3. So let's say b = 3.

Having FOUND that the other two side multiply to 144/3 = 48. Out of the above list there are only two pairs of candidates 4 * 12 and 6 * 8.

Looking at equation 2, then 6(a + b) equals 96. This rules out the 6 and 8.
