The polynomial function f(x) = 3x5 – 2x2 + 7x models the motion of a roller coaster. The roots of the function represent when the roller coaster is at ground level. Which answer choice represents all potential values of when the roller coaster is at ground level? Begin by factoring x to create a constant term. 0, Plus-or-minus one-seventh, Plus-or-minus1, Plus-or-minus three-sevenths, Plus-or-minus3
0, Plus-or-minus one-third, Plus-or-minus1, Plus-or-minus seven-thirds, Plus-or-minus7
Plus-or-minus one-seventh, Plus-or-minus1, Plus-or-minus three-sevenths, Plus-or-minus3
Plus-or-minus one-third, Plus-or-minus1, Plus-or-minus seven-thirds, Plus-or-minus7

i can you with this question sweetie!

step-by-step explanation:

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

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

cant open file sorry!
