Help asaaaap explain please!!!!!
mariarad [96]

Answer:

C

Step-by-step explanation:

Once

\sqrt{xy} = 6

We know that xy = 36

There are infinity values for x, y, but considering x, y \in \mathbb{Z}

Below we have all the solutions for x, y

Negative:

\\x = -36 \text{ and } y = -1\\x = -18 \text{ and } y = -2\\x = -12 \text{ and }  y = -3\\x = -9 \text{ and }  y = -4\\x = -6 \text{ and }  y = -6\\x = -4 \text{ and }  y = -9\\x = -3 \text{ and }  y = -12\\x = -2 \text{ and }  y = -18\\x = -1 \text{ and }  y = -36\\

Positives:

x = 36 \text{ and } y = 1\\x = 18 \text{ and } y = 2\\x = 12 \text{ and }  y = 3\\x = 9 \text{ and }  y = 4\\x = 6 \text{ and }  y = 6\\x = 4 \text{ and }  y = 9\\x = 3 \text{ and }  y = 12\\x = 2 \text{ and }  y = 18\\x = 1 \text{ and }  y = 36\\

We can see that x + y \neq 18

At what point does the curve have maximum curvature? y = 9 ln(x) (x, y) =
Andrews [41]

y = 9ln(x) 
<span>y' = 9x^-1 =9/x</span>
y'' = -9x^-2 =-9/x^2

curvature k = |y''| / (1 + (y')^2)^(3/2) 

<span>= |-9/x^2| / (1 + (9/x)^2)^(3/2) 
= (9/x^2) / (1 + 81/x^2)^(3/2) 
= (9/x^2) / [(1/x^3) (x^2 + 81)^(3/2)] 
= 9x(x^2 + 81)^(-3/2). 

To maximize the curvature, </span>

we find where k' = 0. <span>
k' = 9 * (x^2 + 81)^(-3/2) + 9x * -3x(x^2 + 81)^(-5/2) 
...= 9(x^2 + 81)^(-5/2) [(x^2 + 81) - 3x^2] 
...= 9(81 - 2x^2)/(x^2 + 81)^(5/2) 

Setting k' = 0 yields x = ±9/√2. 

Since k' < 0 for x < -9/√2 and k' > 0 for x > -9/√2 (and less than 9/√2), 
we have a minimum at x = -9/√2. 

Since k' > 0 for x < 9/√2 (and greater than 9/√2) and k' < 0 for x > 9/√2, 
we have a maximum at x = 9/√2. </span>

x=9/√2=6.36

<span>y=9 ln(x)=9ln(6.36)=16.66</span>  

the answer is
(x,y)=(6.36,16.66)
