Write the equation of the parabola in vertex form.
vertex (2,1), point (3,- 1)
f(x) =

Step-by-step explanation:

Given the vertex, (2, 1) and point (3, -1):

We can plug in those values into the Vertex Form:

Plug in the other point, (3, -1) into the equation to solve for a:

-1 = a1 + 1

Subtract 1 from both sides of the equation to solve for a:

-1 - 1 = 1a + 1 - 1

-2 = 1a

-2 = a

Therefore, the equation of the parabola in Vertex Form is:

where a = -2, and the vertex, (2, 1) as its maximum point.

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
