You are going on a road trip over a distance of 3000 kilometers with three friends. the car consumes 66 liters of gas per 100 kilometers and gas costs $1.20 per liter.

if you want to split the cost of gas evenly between the four of you, how much should each of you chip in?

Each person should chip in $0.83

Step-by-step explanation:

Total cost =3000km(66/100)(1.20/L)

                   =45.46 × 1.20

                     =$54.55

Cost per person = ($54.55/66)

                            =$0.83 person

Each person should chip in $0.83

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

answer: sorry

step-by-step explanation: can you tell me pls how to find the rational of two integers
