Question about Matlab, thank you

1. An object with an initial temperature To placed inside a chamber with constant temperature Tm at time t 0 will have a temperature change according to -kt where T(t) is the temperature at time t hours and k is a constant. (a) Write a function (separate file!) called cooling.m that calculates the temperature of a soda can in a refrigerator after time t. Your function should take in the inputs TO, Tm, t, and output Temp. After all the variables are defined, set up the calculation using one Matlab command. You may assume k 0.03. (b) In your main script Projectl.m, determine the temperature of a soda can after 3 hours 80F and refrigerator by calling the function cooling, with starting temperature To temperature T 361F
