Let f(x) = 1 x and g(x) = 1 x if x > 0 8 + 1 x if x < 0 show that f '(x) = g'(x) for all x in their domains. can we conclude from the corollary below that f − g is constant? if f '(x) = g'(x) for all x in an interval (a, b), then f − g is constant on (a, b); that is, f(x) = g(x) + c where c is a constant. for x > 0, f(x) = g(x), so f '(x) = g'(x). for x < 0, f '(x) = and g'(x) = , so f '(x) g'(x). however, the domain of g(x) is not an interval [it is (−[infinity], 0) ∪ (0, [infinity])] so we cannot conclude that f − g is constant (in fact it is not).

hi, i am not sure about this one but i think its d,

hope this !

i think this could be a possible answer (1 / 84) -1

good luck! : d

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

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
