What is the equation of the ellipse with foci (5, 0), (-5, 0) and co-vertices (0, 4), (0, -4)?

The curve equation y3 + 3yx - x3 = 9

Differentiate implicitly with respect to x.

3y2(dy/dx) + 3[y + x(dy/dx)] - 3x2 = 0

3y2(dy/dx) + 3y + 3x(dy/dx)] = 3x2

(dy/dx)(3y2 + 3x) = 3x2 - 3y

dy/dx = 3(x2- y)/3(y2 + x)

dy/dx = (x2- y)/(y2 + x)

b 1: 45 am

step-by-step explanation:

its that because if it was in the pm it would be 1345

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
