Find the second derivative of 2x^3-3y^2=8​
Umnica [9.8K]

Answer:

\frac{d^2y}{dx^2}=\frac{x(2y-x^3)}{y^3}

Step-by-step explanation:

<u>Find the first implicit derivative using implicit differentiation</u>

<u />2x^3-3y^2=8\\\\6x^2-6y\frac{dy}{dx}=0\\ \\-6y\frac{dy}{dx}=-6x^2\\ \\\frac{dy}{dx}=\frac{x^2}{y}

<u>Use the substitution of dy/dx to find the second derivative (d²y/dx²)</u>

<u />\frac{d^2y}{dx^2}=\frac{(y)(2x)-(x^2)(\frac{dy}{dx})}{y^2}\\ \\\frac{d^2y}{dx^2}=\frac{2xy-(x^2)(\frac{x^2}{y})}{y^2}\\\\\frac{d^2y}{dx^2}=\frac{2xy-\frac{x^4}{y}}{y^2}\\\\\frac{d^2y}{dx^2}=\frac{x(2y-x^3)}{y^3}

How many mor barrel of gasoline than diesel were produced last year
algol [13]

Answer:

3 million barrels

Step-by-step explanation:

Total crude oil=60 million barrels

gasoline 34% diesel 29% total crude oil -60 million barrel · =0.34 times 60

Diesel=20,400,000 and gasoline=17,400,000

Quantity of gasoline = 34% of total crude oil

=0.34 times 60 =20.4

Quantity of diesel = 29% of total crude oil

=0.29 times 60 { million barrels}

Clearly, Quantity of gasoline is more than Quantity of diesel

difference = Quantity of gasoline-Quantity of diesel

20.4 -17.4 milion barrels

Therefore,

The production of gasoline is 3 million barrels more than diesel last year.
