The calculation should be coding in MATLAB. Shows all the coding part.

a. The equation of a circle in the x-y plane with radius R and its center at point (2,4) is given by (x-2)2 + (y-4)2 = R2. The equation of a line in the plane is given by y=x/2 + 1. Determine the coordinates of the points (as function of R) where the line intersects the circle. b. Chemical reaction rates are proportional to a rate constant, k that changes with temperature, T according to Arrhenius equation k = Aero For a certain reaction, Q=8000 cal/mol, R=1.987 cal/mol.K) and A=1200 min-' were recorded. By using Simulink, determine the value of k for temperature from 700 K. The output of the simulation will be displayed
