Web24 feb. 2024 · If one atom decays, the Geiger counter observes that decay and responds to it automatically. The GC "discharges". The discharge hits a relay, which triggers a hammer, which breaks the vial. Up until that time, the cat is alive. After it, the cat dies. If no atom decays within the allotted hour, the cat lives. The cat is never both alive and dead. WebSystems of Equations Calculator is a calculator that solves systems of equations step-by-step.

Webthe discriminant is: Δ = b2 − 4ac. The discriminant can be used to characterize the solutions of the equation as: 1) Δ > 0 two separate real solutions; 2) Δ = 0 two coincident real solutions (or one repeated root); 3) Δ < 0 no real solutions. For example: x2 −x −2 = 0. Where: a = 1, b = −1 and c = −2. Web14 nov. 2014 · How many solutions does linear equation in two variable have?
