Reduction of the amount of waste entering the waste stream is called __________

Marta_Voda [28]

The answer that fits the blank is SOURCE REDUCTION. Source reduction refers to the prevention of further pollution by eliminating the source before this can produce the wastes. This helps in the reduction of pollution, thus reduces the amount of toxins brought by these wastes that may harm the environment.

The coordinates of a particle in the metric xy-plane are differentiable functions of time t with StartFraction dx Over dt EndFr

Brut [27]

Answer:

$\dfrac{dD}{dt}=-7.076\ m/s$

Explanation:

It is given that,

The coordinates of a particle in the metric xy-plane are differentiable functions of time t are given by :

$\dfrac{dx}{dt}=-6\ m/s$

$\dfrac{dy}{dt}=-4\ m/s$

Let D is the distance from the origin. It is given by :

$D^2=x^2+y^2$

Differentiate above equation wrt t as:

$2D\dfrac{dD}{dt}=2x\dfrac{dx}{dt}+2y\dfrac{dy}{dt}$

$D\dfrac{dD}{dt}=x\dfrac{dx}{dt}+y\dfrac{dy}{dt}$ .............(1)

The points are given as, (12,5). Calculating D from these points as :

$D=\sqrt{12^2+5^2} =13\ m$

Put all values in equation (1) as :

$13\times \dfrac{dD}{dt}=12\times (-6)+5\times (-4)$

$\dfrac{dD}{dt}=-7.076\ m/s$

So, the particle is moving away from the origin at the rate of 7.076 m/s. Hence, this is the required solution.
