Proof that x^y + y^x > 1 for all x,y > 0 ...?

Answers

To prove this inequality we need to consider three cases. We need to see that the equation is symmetric and that switching the variables x and y does not change the equation.

Case 1: x >= 1, y >= 1

It is obvious that

 x^y >= 1, y^x >= 1
 x^y + y^x >= 2 > 1
 x^y + y^x > 1

Case 2: x >= 1, 0 < y < 1

 Considering the following sub-cases:

  - x = 1, x^y = 1
  - x > 1,

    Let x = 1 + n, where n > 0

    x^y = (1 + n)^y = f_n(y)

    By Taylor Expansion of f_e(y) around y = 0,

    x^y = f_n(0) + f_n'(0)/1!*y + f_n''(0)/2!*y^2 + ...
        = 1 + ln(1 + n)/1!*y + ln(1 + n)^2/2!*y^2 + ...

    Since ln(1 + n) > 0,

    x^y > 1

  Thus, we can say that x^y >= 1, and since y^x > 0.

  x^y + y^x > 1

  By symmetry, 0 < x < 1, y >= 1, also yields the same.

Case 3: 0 < x, y < 1

  We can prove this case by fixing one variable at a time and by invoking symmetry to prove the relation.

  Fixing the variable y, we can set the expression as a function,

  f(x) = x^y + y^x
  f'(x) = y*x^(y-1) + y^x*ln y 
  For all x > 0 and y > 0, it is obvious that
  f'(x) > 0.

  Hence, the function f(x) is increasing and hence the function f(x) would be at its minimum when x -> 0+ (this means close to zero but always greater than zero). 

  lim x->0+ f(x) = 0^y + y^0 = 0 + 1 = 1

  Thus, this tells us that 

  f(x) > 1.

  Fixing variable y, by symmetry also yields the same result: f(x) > 1.

  Hence, when x and y are varying, f(x) > 1 must also hold true.
    Thus, x^y + y^x > 1.

We have exhausted all the possible cases and shown that the relation holds true for all cases. Therefore, 

  x^y + y^x > 1

What is the prime factorization of 19??

Answers

19 is already a prime number......so ur answer would be 19 or 19 x 1

The prime factorization of 19 is 19, as it is a prime number and can only be divided by 1 and itself.

To determine the prime factorization of a number, we identify all the prime numbers that multiply together to give the original number. In the case of 19, we need to check if it can be divided by any primes (like 2, 3, 5, 7, 11, 13, 17).

After testing, we find that 19 is only divisible by 1 and itself, making it a prime number. Therefore, the prime factorization of 19 is simply 19.

Divide £42 in a ratio of 4:6

Answers

4:6
4+6 =10

£42 / 10 = £4.20

£4.20 * 4 = £16.80
£4.20 * 6 = £25.20

Please make this answer the brainiest!

Explanation on dividing £42 in the ratio of 4:6 into two parts accurately.

Divide £42 in a ratio of 4:6:

Calculate the total parts in the ratio, which is 4 + 6 = 10.

Divide £42 by 10 to find the value of one part: £42 ÷ 10 = £4.20.

Multiply £4.20 by the parts in each ratio: £4.20 x 4 = £16.80 for the first part (4 parts),

£4.20 x 6 = £25.20 for the second part (6 parts).

Saturated hydrocarbons are relatively unreactive except in the presence of _____.

high temperatures and oxygen
other alkanes
alkenes
oxygen

Answers

Answer: high temperatures and oxygen

Answer:

Saturated hydrocarbons are relatively unreactive except in the presence of high temperatures and oxygen.      

Step-by-step explanation:

we have to choose the option in which saturated hydrocarbons react.

Saturated hydrocarbons do contain double and triple bonds that make molecule reactive. They only contains sigma bonds, which are very stable and difficult to break and hence these are unreactive.

In saturated hydrocarbons the percentage of carbon is lower which gets easily oxidised in oxygen of the air to form [tex]CO_2[/tex] completely.

Saturated hydrocarbons are generally unreactive, but when exposed to high temperatures and oxygen they react in a combustion reaction to produce Carbon Dioxide and Water.

Hence, Saturated hydrocarbons are relatively unreactive except in the presence of high temperatures and oxygen.

Option option 1 is correct.

Find the equations of all lines tangent to y = 9–x^2 that pass through the point (1, 12). ...?

Answers

Final answer:

The equation of the line tangent to y = 9 - x^2 that passes through the point (1, 12) is y = -2x + 14.

Explanation:

To find the equations of all lines tangent to y = 9 - x^2 that pass through the point (1, 12), we need to find the slope of the tangent line at the point (1, 12) and use it to form the equation of the line.

First, find the derivative of y = 9 - x^2 to get dy/dx = -2x.Substitute x=1 into dy/dx = -2x to find the slope of the tangent line at (1,12). In this case, the slope is -2.Next, use the point-slope form of a line and the given point (1, 12) to write the equation of the tangent line:

y - y1 = m(x - x1)

y - 12 = -2(x - 1)

Rewrite the equation in slope-intercept form:

y = -2x + 14

Therefore, the equation of the line tangent to y = 9 - x^2 that passes through the point (1, 12) is y = -2x + 14.

answer is B.) 3287
hope that helps
..................................

4325/25 = 173

173 * 19 = 3287

Answer:

B.3287

Step-by-step explanation:

We are given that

b(x) varies directly with x.

b(x)=4325 when x=25

We have to find the value of b(x) when x=19

According to question

[tex]b(x)\propto x[/tex]

[tex]b(x)=kx[/tex]

Where k=Proportionality constant

Substitute the values then we get

[tex]4325=k(25)[/tex]

[tex]k=\frac{4325}{25}=173[/tex]

[tex]k=173[/tex]

Now, substitute the value of k then, we get

[tex]b(x)=173 x[/tex]

Substitute the value of x=19

Then, we get

[tex]b(x)=173 \times 19=3287[/tex]

Hence, option B is true.

The Vertical Angles Theorem states that if two angles are vertical angles, then they are congruent .Given <A and <B are vertical angles so they are equal.

<A=<B.

Measure of <A=x and <B=5x-80

Or  5x-80=x

Adding 80 both sides

5x-80+80=x+80

5x=x+80

Subtracting x both sides

5x-x=x-x+80

4x=80

Dividing both sides by 4

x=20

Measure of <A= x= 20 degrees.

Answer:

Option 3rd is correct

4: 3

Step-by-step explanation:

Perimeter(P) of rectangle is given by:

[tex]P =2(l+w)[/tex]

where, l is the length and w is the width of the rectangle respectively.

Given that:

The dimensions of a smaller rectangle are 3 ft. by 9 ft.

Perimeter of smaller rectangle= 2(3+9) =2(12) = 24 ft.

It is also given that: The dimensions of a larger rectangle are 5 ft. by 11 ft.

Perimeter of Larger rectangle = 2(5+11) =2(16) = 32 ft.

We have to find  the ratio of the perimeter of the larger rectangle to the perimeter of the smaller rectangle.

[tex]\frac{\text{Perimeter of the larger rectangle}}{\text{Perimeter of the Smaller rectangle}}[/tex]

Substitute the given values we have;'

[tex]\frac{32}{24}=\frac{4}{3}[/tex]

Therefore,  the ratio of the perimeter of the larger rectangle to the perimeter of the smaller rectangle is, 4 : 3

21 miles per gallon: 21 x 15 = 315 Miles.

I hope this helps!

Answer:

Toy truck will drive 315 miles since last the tank was filled.

Step-by-step explanation:

BTW troy truck has tank of capacity = 30 gallons

Since the toy truck is half filled so gas in the tank = [tex]\frac{30}{2}[/tex]

                                                                                  = 15 gallons of gas

Average of the toy truck is given as = 21 miles per gallon

That means in 1 gallon truck travels = 21 miles

Therefore in 15 gallons of gas truck will travel = 21 × 15

                                                                             = 315 miles

Toy truck will drive 315 miles since last the tank was filled.

What percent of 77 is 7?

Answers

The value "7" is approximately 9.09 percent of the number "77".

To calculate what percent of 77 is 7, we need to find the proportion of 7 in relation to 77. The concept of percent is based on the idea of expressing a fraction of a whole as a value out of 100.

To find the percentage, we divide the given value (7) by the total value (77) and multiply by 100.

⇒ (7/77) × 100 = 0.0909 × 100 ≈ 9.09%,

Therefore, 7 is approximately 9.09% of 77. This means that 7 represents about 9.09% of the total value of 77. It reflects the proportion of 7 within the whole value of 77, expressed as a percentage.
