Two opposite forces which are acting perpendicular to an axis cause the moment of couple or torque.

<h3>What is couple?</h3>

Couple is the pair of force of equal magnitude which acts in opposite direction to each other. The moment of couple is known as the troque, which can be calculate as,

$\tau=Fs$

Here, (F) is the magnitude of one of the force and (s) is the perpendicular distance of force acting on axis.

Here, the two opposite forces are given which acts perpendicular to an axis. Now suppose there is the magnitude of both the force (F) is equal and the perpendicular distance from the axis is also same.

Thus, from the above definition of moment of couple, they produce, torque or moment of couple.

Hence, the two opposite forces which are acting perpendicular to an axis cause the moment of couple or torque.

Given the function f(x) = 3(x – 2)2 + 4 with a restricted domain of x ≥ 2, which of the following represents f–1(x)?.

Debora [2.8K]

The inverse of the function is $f^{-1}x= \sqrt{\frac{x-4}{3} } + 2$

<h3 /><h3>Domain and Range of functions</h3>

Given the function

$f(x) = 3(x - 2)^2 + 4$

To get the inverse, you will follow the same step as shown:

Rewrite the equation to have:

$y= 3(x - 2)^2 + 4$

Replace x with y

$x = 3(y - 2)^2 + 4$

<h3>Make y the subject of the formula</h3>

$x = 3(y - 2)^2 + 4\\x-4=3(y - 2)^2\\\frac{x-4}{3} = (y-2)^2\\ y-2=\sqrt{\frac{x-4}{3} } \\y = \sqrt{\frac{x-4}{3} } + 2$

Hence the inverse of the function is $f^{-1}x= \sqrt{\frac{x-4}{3} } + 2$

Which of the following best describes why ddt is classified as a persistent organic pollutant.

Ostrovityanka [42]

The reasons why DDT is classified as a persistent organic pollutant are;

DDT can be used to control diseases, such as malaria and typhus, that are spread by insects.

DDT is detected in food worldwide and the general human population is most commonly exposed to the toxin through food.

Persistent Organic Pollutants can be regarded as toxic substances which are made up of organic chemical compounds.

These are industrial chemicals such as;

PCBs

pesticides like DDT.

DDT is classified as a persistent organic pollutant because of it's usefulness in control diseases and it is been found in food stuff across the globe.
