16711.	Differentiate y=x^y with respect to x
Answer» The equation in your QUESTION actually DEFINES two DIFFERENT functions: One, which could be expressed explicitly. is the TRIVIAL one, namely y=x, and along that one the answer to your question is clearly y’=1. The second one is an implicit function y=y(x) which we we are unable to DESCRIBE explicitly in terms of elementary functions. However, by a well known theorem in calculus of functions of several variables, known as the Implicit Function Theorem, once an implicit function y=f(x) is given by an equation of the form F(x,y)=0, where F(x,y) is a given function with continuous partial derivatives with respect to both variables x and y, and its partial derivative with respect to y is non vanishing at a point (a,b) which satisfies F(a,b)=0, i.e. f(a)=b, then the implicit function y=f(x) is differentiable at x=a with derivative given by: y’(a)=-(dF(a,b)/dx)/(dF(a,b)/dy)(a,b) (where dF(a,b)/dx and dF(a,b)/dy standing for the 2 partial derivatives of F(x,y) at (a,b) ) In the case we are talking about, it would be easier to write the equation x^y=y^x as F(x,y)=ylog(x)-xlog(y)=0. Then we can easily apply the Implicit Function Theorem to that equation, and to any point (a,b) satisfying F(a,b)=0 (that is a^b=b^a ), provided that a and b are unequal (e.g. a=2, b=4) , and since dF/dx(a,b)=b/a-log(b)=(b-alog(b))/a=(b-blog(a))/a=b(1-log(a)/a, dF/dy(a,b)=log(a)-a/b=(blog(a)-a)/b=(alog(b)-a)/b=a(log(b)-1)/b we deduce: y’(a)=-((b/a)^2)(1-log(a))/(log(b)-1) For example, for a=2, b=4 one gets y’(2)=-4(1-log(2))/(log(4)-1)=-3.17739889912418….

Answer» ANSWER:Here, x=-25/17 and y= 6/17 Step-by-step explanation: 2x-3y=-4........(i) X+7y=1........... (ii) Now, x+7y=1 =>x=1-7y.............. (iii) SUBSTITUTING the VALUE of x in eq (i) ,we get 2(1-7y) -3y= -4 =>2-14y-3y= -4 =>2-17y= -4 => -17y= -6 =>y=6/17 Again, PUTTING the value of y in eq (iii) we get x=1-7y =1-7(6/17) =1-42/17 =(17-42/17) = -25/17 Therefore, x=-25/17 and y=6/17 Hope it helped you Try your best.

Solve by substitution method the following problems:a)2x-3y+4=0,x+7y-1=0

Answer»

ANSWER:Here, x=-25/17 and y= 6/17

Step-by-step explanation:

2x-3y=-4........(i)

X+7y=1........... (ii)

Now,

x+7y=1

=>x=1-7y.............. (iii)

SUBSTITUTING the VALUE of x in eq (i) ,we get

2(1-7y) -3y= -4

=>2-14y-3y= -4

=>2-17y= -4

=> -17y= -6

=>y=6/17

Again,

PUTTING the value of y in eq (iii) we get x=1-7y

=1-7(6/17)

=1-42/17

=(17-42/17)

= -25/17

Therefore, x=-25/17 and y=6/17

Hope it helped you

16724.

If 18, a, b, -3 are in AP, then a+ b is

Answer»

Answer:

Let d be the common difference

a - 18 = $d_{1}$

B - a = $d_{<klux>2</klux>}$

- 3 - b = $d_{3}$

As we KNOW that the d is same throughout the AP

So we can say that

$d_{1}$ = $d_{2}$ = $d_{3}$

putting the VALUES of $d_{1}$ & $d_{2}$

a - 18 = b - a

b = 2a - 1 8

now putting the value of $d_{2}$ & $d_{3}$

b - a = -3 -b

2b -a = 18 - 3

2( 2a - 18) - a = 15

4a - a = 15 + 36

3a = 51

a = 17

b = 2a - 18

b = 2(17) - 18

b = 34 -18

b = 16

finding a + b

= 17 + 16

= 33

4 /3 tan2 30 + sin 2 60

Answer»

Answer:

Just remember some values

tan30 = 1/√3

TAN 60 = tan(90-30)= cot 30 = √3

cos60 = 1/2

tan 45 = 1

So

4/3 tan2 30 + sin2 60 - 3COS2 60 + tan2 60 3/4. - 2 tan2 45

= 4/3 × 1/3 + sin2 60 + cos2 60 - 4 cos2 60 + 9/4 - 2

= 4/9. + 1 - 4/4 + 9/4 -2

= 4/9 +1-1 +9/4 -2

= 16 + 81 - 72)/36

= 25/36

Answer» Answer: Step-by-step explanation: x² - 55X + 750 = 0 By SPLITTING the MIDDLE term ➾ x² - 25x - 30x + 750 = 0 Factor the expressions ➾ x(x - 25) - 30(x - 25) = 0 Factor the expression ➾ (x - 25) (x - 30) = 0 Split into possible cases ➾ x - 25 = 0 x - 30 = 0 Solve the equations ➾ x = 0 + 25 x = 0 + 30 ➾ x = 25 x = 30

16745.

Factories x2 - 55x + 750 =0

Answer»

Answer:

Step-by-step explanation:

x² - 55X + 750 = 0

By SPLITTING the MIDDLE term

➾ x² - 25x - 30x + 750 = 0

Factor the expressions

➾ x(x - 25) - 30(x - 25) = 0

Factor the expression

➾ (x - 25) (x - 30) = 0

Split into possible cases

➾ x - 25 = 0

x - 30 = 0

Solve the equations

➾ x = 0 + 25

x = 0 + 30

➾ x = 25

x = 30
