If a^2+b^2+c^2 +170 = 2(8a+5b-9c) then find the value of (4a+8b-c)^0.5

Answer»

SOLUTION

GIVEN

$\displaystyle \sf{ {a}^{2} + {b}^{2} + {c}^{2} = 2(8a + 5b - 9c) }$

TO DETERMINE

The value of

$\displaystyle \sf{ {(4a + 8b - c)}^{0.5} }$

EVALUATION

$\displaystyle \sf{ {a}^{2} + {b}^{2} + {c}^{2} = 2(8a + 5b - 9c) }$

$\displaystyle \sf{ \implies \: {a}^{2} + {b}^{2} + {c}^{2} - 2(8a + 5b - 9c) = 0 }$

$\displaystyle \sf{ \implies \: {a}^{2} - 16a + 64 + {b}^{2} - 10b + 25+ {c}^{2} + 18c + 81 = 0 }$

$\displaystyle \sf{ \implies \: {(a - <klux>8</klux>)}^{2} + {(b - 5)}^{2} + {(c + 9)}^{2} = 0 }$

We know if the SUM of the squares of three Real Numbers are zero then they are separately zero

Thus we GET

a - 8 = 0 , b - 5 = 0 , c + 9 = 0

Consequently we get

a = 8 , b = 5 , c = - 9

$\displaystyle \sf{ {(4a + 8b - c)}^{0.5} }$

$\displaystyle \sf{ = {(32 + 40 + 9)}^{0.5} }$

$\displaystyle \sf{ = {(81)}^{0.5} }$

$\displaystyle \sf{ = {(81)}^{ \frac{1}{2} } }$

$= 9$

Answer»

ANSWER:

here is your answer

Given

X + y = 2

xy = 1

Find

X4 + y4

Formula

(x² + y²)² = x4 + y4 + 2x²y²

solution

x² + y² -2xy = 3

23² = x4 + y4 +2(10)²

529 = x4 + y4 +200

x4 + y4 = 529 - 200

3905.

The perimeter of rectangular filed is 82m and it's area is 400m^2.find the dimension of the field

Answer»

Step-by-step EXPLANATION:

LET the breadth of the rectangle be x metres,

then perimeter=82m

⇒2(Length+Breadth)=82

⇒Length+x=41

⇒Length=41−xmetres

Now, Area=400m2

⇒Length×Breadth=400⇒(41−x)x=400

⇒41x−x2=400⇒x2−41x+400=0⇒x2−25x−16x+400=0⇒(x−25)(x−16)=0

⇒x=25orx=16

Hence, breadth =25m or 16M

X^16-y^16 solve the factor

Answer»

Step-by-step EXPLANATION:

x¹⁶-y¹⁶

= (x8)² = (y³)² - = (x³ +y³)(x² − y³)

| Since, a² — b² = (a + b)(U = b)

= (x8+y³)[(x¹)²-(3¹)²]

= (x³ +y³)(x² + y²)(x² − y¹) =

= (x³ +y³)(x¹+y¹) [(x²)² – (y²)²]

Answer» First of all, it increases (as gas molecules are more disordered so have higher entropy but be mindful as steam isn't gas, just closer and with higher energy ) so your ANSWER will be positive. Step-by-step explanation: The nth term formula goes by :if a system has x times different ENVIRONMENTS and y times particles, the entropy is y^x that's for a small number of particles. You can't use that here. Okay, sorry, listen here. You're going to need two formulas : a) the formula for gibbs free energy (Gibbs free energy as it relates enthalpy change to entropy change) which is ==> GibbsFE change= Enthalpy change - Entropy change×temperature b) The molar gas formula PV=nRT c) find the molecular formula of H2O which will be 16+2= 18 d) the formula for entropy change which is :Entropy change= Reversible energy transfered \Kelvin temperature So 2.0kg x 1000= 2000 grams 2000\18 will give you the number of moles. Anyway what I'm telling you is based on the A level QUALIFICATION, so it might not be more into depth. I've got a WHOLE LOT of math to learn rn so sorry i couldn't finish.

3919.	Which among these is a divisible product of two consecutive integers?option 3275
Answer» Answer: let the first integer be x then the second integer shall be x+1 then their product be x(x+1) = x²+x (i) If x is even then x = 2k ∴ x²+x= (2k)²+2k =4k²+2k =2(2k²+k) hence DIVISIBLE by two. (ii)Let x be odd. ∴ x= 2k+1 ∴ x²+x = (2k+1)²+2k+1 =(2k)²+8k+1+2k+1 =4k²+10k+2 =2(2k²+5k+1) hence divisible by two/. since bothe of our conditions satisfy the statement, we can say that the product of two consecutive integers is divisible b Step-by-step explanation: one more here It is true that product of two consecutive +ve integers is divisible by 2 as because of the following reasons:- Let U consider two consecutive +ve integer as N and ANOTHER as n-1. Now, the product of both is n2-n Case 1 When n=2q ( Since any +ve integer can be in the form of 2q or 2q+1) n2-n= (2q)2-2q = 4q2- 2q It is divisible by 2 as it leaves a remainder 0 after division. Case 2 When n= 2q+1 n2-n = (2q+1)2 - 2q+1 = 4q2+ 4q+2q+2 = 4q2+ 6q+2 It is divisible by 2 So, in both the case of the consecutive integers, it is divisible by 2

3919.

Which among these is a divisible product of two consecutive integers?option 3275

Answer»

Answer:

let the first integer be x

then the second integer shall be x+1

then their product be x(x+1) = x²+x

(i) If x is even

then x = 2k

∴ x²+x= (2k)²+2k

=4k²+2k

=2(2k²+k)

hence DIVISIBLE by two.

(ii)Let x be odd.

∴ x= 2k+1

∴ x²+x = (2k+1)²+2k+1

=(2k)²+8k+1+2k+1

=4k²+10k+2

=2(2k²+5k+1)

hence divisible by two/.

since bothe of our conditions satisfy the statement, we can say that the product of two consecutive integers is divisible b

Step-by-step explanation:

one more here

It is true that product of two consecutive +ve integers is divisible by 2 as because of the following reasons:-

Let U consider two consecutive +ve integer as N and ANOTHER as n-1.

Now, the product of both is n2-n

Case 1

When n=2q ( Since any +ve integer can be in the form of 2q or 2q+1)

n2-n= (2q)2-2q

= 4q2- 2q

It is divisible by 2 as it leaves a remainder 0 after division.

Case 2

When n= 2q+1

n2-n = (2q+1)2 - 2q+1

= 4q2+ 4q+2q+2

= 4q2+ 6q+2

It is divisible by 2

So, in both the case of the consecutive integers, it is divisible by 2

ANSWER:

hey here is your answer

pls MARK it as brainliest

Step-by-step EXPLANATION:

$so \: here \: a \: storage \: tank \: constructed \: by \: a \: farmer \: is \: made \: up \: of \: two \: geometrical \: shapes \: namely \: cylinder(lower \: part) \: and \: cone(upper \: part) \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: (given)$

$so \: thus \: then \: radius \: of \: both \: cylindrical \: and \: conical \: shape \: would \: be \: equal \\ so \: let \: the \: radius \: of \: entire \: storage \: tank \: be \: r \: (inclusive \: of \: conical \: part \: and \: cylindrical) \\ here \: diameter(d) = 8.cm \\ thus \: radius(r) = 4.cm$

$moreover \\ for \: a \: cylindrical \: part \\ vertical \: height \: ie \: perpendicular \: height(h) = 3.5 \: cm \\ \\ for \: a \: conical \: part \: \\ height(H) = 1.2 \: cm$

$so \: thus \: combined \: volume(inclusive \: volume) \: of \: storage \: tank = volume \: of \: cylindrical \: part + volume \: of \: conical \: part$

$so \: we \: know \: that \\ volume \: of \: conical \: part = 1/3 \times \pi \: r.square \: H \\ volume \: of \: cylindrical \: part = \pi \: r.squre \: h$

$thus \: then \\ volume \: of \: storage \: tank = 1/3 \times \pi \: r.square \: H + \pi \: r.square \: h \\ = \pi \: r.square(1/3.H + h) \\ = 3.14 \times (4).square (1/3 \times 1.2 + 3.5) \\ = 3.14 \times 16(0.4 + 3.5) \\ = 50.24 \times 3.9 \\ = 195.936 \\ \\ so \: volume \: of \: storage \: tank = 195.936 \: cubic.cm$

$but \: as \: we \: know \: that \\ 1l = 1000 \: cubic.cm \\ so \: 195.936 \: cubic.cm = 195.936 \times 1000 \: l \\ = 195936 \: l$

$so \: thus \: capacity \: of \: given \: storage \: tank \: is \: about \: 195936 \: l$
