Una ciudad sostenible es aquella que se construye bajo unas reglas y normas a concordancia de la ética ambiental y la planificación urbana. Además, es un concepto reciente con una popularidad creciente ya...

If you are given the equation y = x²+4x+1 First you determine what is in the squareMake sure your x² term has no coefficientFind half the coefficient of the x termThat is your brack...

If the function is even, f(x) = f(-x).cos(-x) is the same value as cos(+x) therefore the function is even. Its graphical property is that it is symmetrical about the y axis as all even functions are.

since the values are too difficult to calculate from factorising, we use the quadratic formula ((-b)±(b^2-4ac)^(1/2))/(2a).putting the values in as (ax^2+bx+c=0) we find the roots in exact form are;(-11+(...
