Determine the truth value of each of these statements if the domain of each variable consists of all real num- bers. a) vx3y(x² = y) b) vxəy(x = y2) c) 3xvy(xy = 0) d) 3x3y(x + y + y + x)
e) vx(x + 0 → y(xy = 1)) f) 3xvy(y + 0 + xy = 1) g) vx=y(x + y = 1) h) 3x3y(x + 2y = 2 1 2x + 4y = 5) i) vx3y(x + y = 2 1 2x - y = 1) j) vxvy=z(z = (x + y)/2)

your answer would be 12

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
