Find the directional derivative of the function at the given point in the direction of the vector v. f(x, y, z) = xyz , (3, 3, 9

Anna [14]

The derivative of $f(x,y,z)$ in the direction of a vector $\mathbf u$ is

$\nabla_{\mathbf u}f=\nabla f\cdot\dfrac{\mathbf u}{\|\mathbf u\|}$

With $f(x,y,z)=xyz$ , we get

$\nabla f=(yz,xz,xy)$

and $\mathbf u=(-1,-2,2)$ ,

$\|\mathbf u\|=\sqrt{(-1)^2+(-2)^2+2^2}=3$

Then

$\nabla_{(-1,-2,2)}f(3,3,9)=(27,27,9)\cdot\dfrac{(-1,-2,2)}3=-21$

This is the equation: ×+2x+5x+1=25 Combine
like terms to get:
8x+1=25 Now subtract 1 from both sides to
result in;
8x=24 Divide 8 into both sides to get:
×=3 inches for the first one.

M∠ABC=138° and m∠DEF=31° .

nikklg [1K]

A)The angles are neither complementary nor supplementary.

Complementary- Two angles whose sum add up to 90° ( a right angle)

Supplementary-Two angels whose sum when added together is 180°

It seems to be a obtuse angle - more than 90° but less than 180°
