en una curva peligrosa, con limite de velocidad a 40kilometros/hora, circula un coche a 36 kilometros/hora, otro dela misma masa 2000 kilogramos no respeta la señal y anda a 72 kilómetros/ hora. ¿ cuales la energía cinética de los coches

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

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.

570, the answer is 570, hope it

answer: 1+1

step-by-step explanation: 1+1 is at least 2
