Round to the tenths place 456.087

xxTIMURxx [149]

Hey!

Tenths place is one number after the decimal point. The tenths place is 0. After the number 0 is 8. Since 8 is equal to or greater than 5, the tenths place goes up by 1.

$0 \rightarrow 1$

Now it becomes:

$456.1$

<em>456.1 is your answer</em>

Find the local extreme values of the function f(x, y) = xy - x2 - y2 - 3x - 3y + 12

aev [14]

$f(x,y)=xy-x^2-y^2-3x-3y+12$

First compute the first-order partial derivatives and find the critical points.

$f_x=y-2x-3$
$f_y=x-2y-3$

Both first order derivatives vanish at $(x,y)=(-3,-3)$ .

Computing the Hessian, we get

$\mathbf H(x,y)=\begin{bmatrix}f_{xx}&f_{xy}\\f_{yx}&f_{yy}\end{bmatrix}=\begin{bmatrix}-2&1\\1&-2\end{bmatrix}$

We have $\det\mathbf H(x,y)=3>0$ , which means $(-3,-3)$ is an extremum of $f(x,y)$ . Since $f_{xx}(-3,-3)=-2$ , this extremum is a local maximum of $f(x,y)$ with a value of 21.
