In Matlab's SIMULINK please solve the following two problems

Problem 7 (a) Use ode45 to plot the solution of the following equation for 105.-7 cos 4t+ 5 sin 3t , 0sts6 y(0)-4 , ?(0)-1 (b) Use Simulink to plot the solution for the same equation, interval, and initial conditions stated above. Problem 8 Use a Simulink model to plot the solution of the following equation for 0sts7. y +2y f(t)y(O)-2 where for Osts2 for 2 st S5 -3(t 5) +6 for 5 St s7 f(t) Problem 7 (a) Use ode45 to plot the solution of the following equation for 105.-7 cos 4t+ 5 sin 3t , 0sts6 y(0)-4 , ?(0)-1 (b) Use Simulink to plot the solution for the same equation, interval, and initial conditions stated above.
