Please help me to do all of these python questions!

Part 3: Modeling viral load and fitting data Now we're going to try to use a combination of the things we' ve learned in the course to do a bit of modeling! Specifically, we're going to use a model for the viral load of a patient with HIV after they've begun a antiretroviral drug treatment. The viral load model provides an estimate for the number of virions in the patient's bloodstream as a tunction of time. The model for the concentrations of HIV in the bloodstream is given by V(1) = A exp(-u) + B exp(-pr) where the four parameters, Aa, B, and are constants that control the behavior of the model. Question 10: Write a function whose parameters are the following: A NumPy array of time values in days . The four parameters of the viral load model. A, a, B, and Your function should return the value of V(t) corresponding to the values in your time array. Call the function viral load. J Put your viral load function here Question 11: Now, create a NumPy array called "time" that goes from 0 to 10 in increments of 0.1 using np.1inspace. Set A 1000.0, B =-500.0, = 1.0, and -5.0 and call your viral-load function to compute the viral load as a function of time. Make a plot of viral load vs. tip Label your plots with appropriate axis labels. : # Put your code here
