solve using MATLAB

Problem 6 [15 Marks] A process adds signals A and B together to generate an output signal c. 1)+sin(t) A5 sin a 20000 B = 100cos - (30000) -cos ( Where a is your candidate number, and t is the time a) Use MATLAB Simulink to model this process when osts 10 seconds, the model must shown in the report b) Display all the positive values of signal Con a scope c) All signals in the system must be displayed on scopes and shown in the report d) The Simulink model and the properties of blocks must be shown in the report
