Find the derivative of f(x) = negative 9 divided by x at x = -4. (6 points) 4 divided by 9 16 divided by 9 9 divided by 16 9 div

Len [333]

Answer:

9/16

Step-by-step explanation:

$f(x)=-\frac{9}{x}$

$f(x)=-9x^{-1}$

Derivative rule:

$f(x)=x^{n} \\$

$\frac{df}{dx}=nx^{n-1}$

Here, n=-1, so

$\frac{df}{dx}=(-9)(-1)x^{-2} =\frac{9}{x^{2} }$

Evaluating this at x=-4 gives 9/16

Consider parallelogram ABCD. Which of the following transformations will change the perimeter of the parallelogram?

jeka57 [31]

In geometry, transformation involves changing the position and/or size of a shape.

The transformation that will change the size of ABCD is dilation.

There are four transformations in geometry:

Translation
Reflection
Rotation
Dilation

Of all types of transformation, dilation will change the size of the shape,

The new shape will either be enlarged or reduced

Either ways, the size of the shape will be altered.

When the size is altered, the perimeter will not remain the same.

Hence. dilation will change the perimeter of ABCD.
