assume x and y are both differentiable functions of t. find dx/dt given x=-1 and dy/dt=8 for the relation: 4x^2+3y^3=28

melomori [17]

Given:

x and y are both differentiable functions of t.

$4x^2+3y^3=28$

$x=-1\text{ and }\dfrac{dy}{dt}=8$

To find:

The value of $\dfrac{dx}{dt}$ .

Solution:

We have,

$4x^2+3y^3=28$ ...(i)

At x=-1,

$4(-1)^2+3y^3=28$

$4+3y^3=28$

$3y^3=28-4$

$3y^3=24$

Divide both sides by 3.

$y^3=8$

Taking cube root on both sides.

$y=2$

So, y=2 at x=-1.

Differentiate (i) with respect to t.

$4(2x\dfrac{dx}{dt})+3(3y^2\dfrac{dy}{dt})=0$

Putting x=-1, y=2 and $\dfrac{dy}{dt}=8$ , we get

$4(2(-1)\dfrac{dx}{dt})+3(3(2)^28)=0$

$-8\dfrac{dx}{dt}+9(4)(8)=0$

$-8(\dfrac{dx}{dt}-9(4))=0$

Divide both sides by -8.

$\dfrac{dx}{dt}-36=0$

$\dfrac{dx}{dt}=36$

Therefore, the value of $4x^2+3y^3=28$ is 36.

How to slove y=-3x+4

garik1379 [7]

Equation By Substitution/Elimination Method:

y = -3x + 4; y = 4x - 10

Let's solve your system by substitution.

y = −3x + 4; y = 4x − 10

Step: Solve y = −3x + 4 for y:

y = −3x + 4

Step: Substitute −3x + 4 for y in y = 4x − 10:

y = 4x − 10

−3x + 4 = 4x − 10

−3x + 4 + −4x =4x − 10 + −4x (Add -4x to both sides):

−7x + 4 = −10

−7x + 4 + −4 = − 10 + −4 (Add -4 to both sides):

-7x = -14

-7x/ -7 = -14/ -7 ( Divide both sides by -7):

x = 2

Step 2: Substitute 2 for x in y = −3x + 4:

y = −3x + 4

y = (−3)(2) + 4

y = −2 (Simplify both sides of the equation)

Answer:

x = 2 and y = −2

Hope that helps!!!!
