The rate of change of the distance from the particle to the origin at this instant is 3 units per second.

<h3>What is the rate of change?</h3>

The instantaneous rate of change is the rate of change at a particular instant.

A particle is moving along the curve

y= 4\sqrt{5x+11} .

The rate of change of y is given as:

dy / dx = 2

by differentiating both sides,

\dfrac{dy}{dx} = 4\dfrac{1}{2\sqrt{5x+11} }  5\dfrac{dx}{dt} \\\\\dfrac{dy}{dx} = \dfrac{10}{\sqrt{5x+11} }\dfrac{dx}{dt}\\\\

From the question, we have:

(x, y) =  (5,24)

Substitute 5 for x and dy / dx = 2

\dfrac{dy}{dx} = \dfrac{10}{\sqrt{5x+11} }\dfrac{dx}{dt}\\\\\\5= \dfrac{10}{\sqrt{5(5)+11} }\dfrac{dx}{dt}\\\\\\\sqrt{5(5)+11} = 2\dfrac{dx}{dt}\\\\\\\dfrac{dx}{dt} = 6/ 2 = 3

Hence, the rate of change of the distance from the particle to the origin at this instant is 3 units per second.

Answer:

c(10)=40

c(15)=52.5

Step-by-step explanation:

c(10) means you plug 10 into your x same with (c15) you plug in 15 so for c(10) it would be 2.5(10) + 15 which is 40

Write each fraction or mixed number as a decimal. Use bar notation if needed. Please help and thank you.

You can use your calculator to divide it out and find that

-\dfrac{8}{11}=-0.\overline{72}

or, you can make use of your knowledge of the decimal equivalent if 1/11 (=0.90909...) and multiply that by -8 to get -0.727272... as above.
