Find the focus and the directrix of the parabola with the equation y = –1∕12(x – 4)2 +2. Question 18 options: A) Focus = (4,1), directrix is y = –5 B) Focus = (4,–1), directrix is y = –5 C) Focus = (4,–1), directrix is y = 5 D) Focus = (4,2), directrix is y = 5

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
