Find the second derivative at the point (1,2), given the function below. x^3+5x+y=y^3 Round answer to 3 decimals.
Savatey [412]

Answer:

-0.032

Step-by-step explanation:

The given equation is

{x}^{3}  + 5x + y =  {y}^{3}

We differentiate implicitly to get:

3{x}^{2}  + 5 +  \frac{dy}{dx} = 3 {y}^{2} \frac{dy}{dx}

\frac{dy}{dx}  -  3 {y}^{2} \frac{dy}{dx}  = - ( 3{x}^{2}  + 5)

(1  -  3 {y}^{2} )\frac{dy}{dx}  = - ( 3{x}^{2}  + 5)

\frac{dy}{dx}  = \frac{ - ( 3{x}^{2}  + 5)}{1  -  3 {y}^{2} }

\frac{dy}{dx}  = \frac{  3{x}^{2}  + 5}{ 3 {y}^{2} - 1 }

We differentiate again using the quotient rule:

\frac{d^{2} y}{d {x}^{2} }  = \frac{ 6 {x} (3 {y}^{2} - 1) - (3 {x}^{2}  + 5)(6y \frac{dy}{dx})  }{ (3 {y}^{2} - 1)^{2}  }

At (1,2), x=1, and y=2

\frac{d^{2} y}{d {x}^{2} }  = \frac{ 6 { \times 1} (3 { \times 2}^{2} - 1) - (3 { \times 1}^{2}  + 5)(6 \times 2 \times  \frac{8}{11} )  }{ (3 { \times 2}^{2} - 1)^{2}  }

\frac{d^{2} y}{d {x}^{2} }   =  - 0.032

Okay, so we need to plug in -40 C and 125 C into the equation. 

-40= (F- 32)

Add 32 from both sides.

-8= F

125= ( F- 32)

Add 32 to both sides

157 F

-8>x<157 (the inequality) 

More then -8 and less than 157 degrees Fahrenheit.

Have a nice day!
