INTERPRETING THE DISCRIMINANT Consider the equation \(\frac{1}{2} x^{2}+\frac{2}{3} x-3=0\) Evaluate the discriminant.
Use the following information. Scientists simulate a gravity-free environment called microgravity in free- fall situations. A similar microgravity environment can be felt on free-fall rides at amusement parks or when stepping off a high diving platform. The distance \(d\) (in meters) that an object that is dropped falls in \(t\) seconds can be modeled by the equation \(d=\frac{1}{2} g\left(t^{2}\right),\) where \(g\) is the acceleration due to gravity (9.8 meters per second per second). How are these formulas similar? \(d=\frac{1}{2} g\left(t^{2}\right)\) when \(d\) is distance, \(g\) is gravity, and \(t\) is time \(h=-16 t^{2}+s\) when \(h\) is height, \(s\) is initial height, and \(t\) is time
