Consider the following first order differential equation x =ax+bu where a = -2, b=10, u(t)=e-2t and the initial condition is x(o)=5. (1) determine the analytic solution of this differential equation by identifying the expression x(t). (ii) calculate x(t) at t=0.5. (ii) using the explicit euler method with a sample time of 0.25, determine the discrete-time model xx+1=47**+ (iv) calculate xt for the time corresponding to t=0.5.

The correct answer is weight.

Ithink it’s carbon dioxide

Electron equations of the given changes are as follow,a)                              cu      →      cu⁺²  + 2e⁻b)                              mg⁺²  +  2 e⁻      →      mgc)                              cl⁻    →      cl  +  1e⁻d)                              s  +  2 e⁻    →      s²⁻e)                                o²⁻      →      o  +  2 e⁻f)                              p  +  3 e⁻    →      p³⁻g)                              fe²⁺    →      fe³⁺  + 1 e⁻h)                              s²⁻    →      s⁴⁺  +  6 e⁻

The answer is a. that is an exothermic reaction which means it produces heat
