use matlab and screenshot code for both pls

a 3. A species A is fed into a tank at a concentration of C = 2 mol/l. The tank is initially filled with water and A is absent in it. A mixer makes the concentration of A, C, homogeneous in the tank. C, in the output flow of the tank follows the equation 1 dc, where r = 30 sec is the residence time, which is the tank volume divided by volumetric flow rate in inlet and outlet of the tank. Write a Simulink file HW6_3_YourLastName.six to calculate and display C,) over 120 sec. 4. T can be expanded in series as 1 T41 1 1 35 Write a script file HW6_4_YourLastName.m to calculate using the series expansion above with 5x 10 terms. Display the result by format long
