Find dx/dt when y=2 and dy/dt=1, given that x^4=8y^5-240<br><br> dx/dt=

katrin2010 [14]

Answer:

The value of $\frac{dx}{dt}$ is $\frac{160}{x^3}$ .

Step-by-step explanation:

The given equation is

$x^4=8y^5-240$

We need to find the value of $\frac{dx}{dt}$ .

Differentiate with respect to t.

$4x^3\frac{dx}{dt}=8(5y^4)\frac{dy}{dt}-0$ $[\because \frac{d}{dx}x^n=nx^{n-1},\frac{d}{dx}C=0]$

$4x^3\frac{dx}{dt}=40y^4\frac{dy}{dt}$

It is given that y=2 and dy/dt=1, substitute these values in the above equation.

$4x^3\frac{dx}{dt}=40(2)^4(1)$

$4x^3\frac{dx}{dt}=40(16)(1)$

$4x^3\frac{dx}{dt}=640$

Divide both sides by 4x³.

$\frac{dx}{dt}=\frac{640}{4x^3}$

$\frac{dx}{dt}=\frac{160}{x^3}$

Therefore the value of $\frac{dx}{dt}$ is $\frac{160}{x^3}$ .

What is the length of the radius, r? 6 cm 18 cm 36 cm 72 cm.

Rus_ich [418]

The length of the radius of circle o is 18 cm.

<h2></h2><h2>Given that</h2>

Circle o has a circumference of 36π cm.

<h3>We have to determine</h3>

What is the length of the radius, r?

<h3>According to the question</h3>

Circle o has a circumference of 36π cm.

The length of the radius of the circle is determined by the following formula;

$\rm Circumference = 2\pi r$

Substitute all the values in the formula;

$\rm Circumference = 2\pi r\\
\\
36\pi =2\pi r\\
\\
r = \dfrac{36\pi }{2\pi }\\
\\
r = 18 \ cm$

Hence, the length of the radius of circle o is 18 cm.

Enzo drew Triangle K L N. In Enzo’s triangle, Measure of angle K is represented as x degrees. The measure of Angle L is 5 times

anygoal [31]

Answer:

Angle k = 14°,L = 70° and N = 96°

Step-by-step explanation:

According to the question,Enzo drew Triangle K L N. In Enzo’s triangle, Measure of angle K is represented as x degrees. The measure of Angle L is 5 times Measure of angle K. The measure of Angle N is 16 degrees less than 8 times Measure of angle K.

From here,we know that angles in a triangle sum up to 180°

If angle k = x

Angle L = 5x

And angle N = 8x - 16

Sum of a all three is equal to 180°

(8x - 16) + x + 5x = 180

14x -16 = 180

X = 196/14

X= 14.

Therefore,angles k = 14°, L = 70° and N= 96°

Let's now assume that the question was to find the angles k,l and n which is already written above and to pick the correct statement relating to the question.

My statement here is( since we weren't given the complete question) that the triangle is a scalene triangle
