Post Published Solution with Plots using MATLAB

For this problem you need to make 4 plots and placing them on one figure page with subplot(). Plot 1: Atmospheric pressure decreases exponentially. The general formula for exponential growth/decay is y(x) = a e^kx The pressure (depending on the weather) is about 1013 hPa at sea level. Determine k for the generally accepted situation where the pressure is down by about 12% at 1000m above sea level. With climate change, the pressure decay is slightly more drastic. For pressure being down 14% at 1000m, determine the new value of k. Plot these two exponential decays from 0 to 80,000m. For the 12% decrease, the line should be red and solid. For the 14% decrease the line should be blue and dashed. Label the axes and give a title to the figure. Plot 2: Make the same plot as Plot 1, but this time use a logarithmic y-axis. Plot 3: The shape of a pretzel can be generated from two parametric equations. The equations are as follows: x = (3.3 - 0.3t^2) cos(t) y = (3.3 - 0.4t^2)sin(t) where -4
