Can i get the answers 38) What is the benefit of the command close all?39)Can we plot vector X = [3 9 27] over time t = |not?40) Write the Matlab commands that plot the vector X = [11 43 127] overtime t = [1 2 3]. Make sure that the vector t is on the x axis and thevector X is on the y axis.o Add a title to the figure that says "This is a plot of distanceover time"[1 2 3 4]? Why or whyo Add a title to the x axis that says "This is time(s)"o Add a title to the y axis that says "This is distance(m)"41)When do we use a legend in Matlab?42)Given the dependent vectors X, Y, and Z over the independent vector, ifyou know that X = [3 9 27], Y = [10 8 6], Z = [4 4 4], and t=[1 2 3],use legend to plot these multiple dependent vectors on the same plot.o Use green for Xo Use blue for Yo Use red for Zo Add a title to the figure that says "This is a plot of distanceover time"o Add a title to the x axis that says "This is time(s)"o Add a title to the y axis that says "This is distance(m)"o Print the legend boxo Move the legend box to the south east43) What command can we use to display multiple plots on the same figure?44)Given that x = 0:0.1:2*pi do the following using the subplot functiono Define a 2 by 3 subplot figureo In the first box, plot sine xo In the second box, plot cosine xo In the third box, plot negative exponential function of xo In the fourth box, plot x^3o In the fifth box, plot 2*xo In the sixth box, plot x*x45)Create a vector named time of numbers over the range from 0 to 5 withincrement 0.5 every time (Hint, use the colon operator), and then dothe following:o Create another vector named height and set it up equal to 2.13 *time .^2 - 0.13 * time .^4 + 0.000034 * time .^ 4.752o Write a Matlab commands that plot the vector height over time.(Hint, make sure that the vector time is on the x axis and thevector height is on the y axis).o Rewrite the previous command such that the printed line is

The "close all" command in MATLAB is a useful function that allows one to close all open figures,…

38) What is the benefit of the command close all? 39)Can we plot vector X = [3 9 27] over time t = [1 2 3 4]? Why or why not? 40)Write the Matlab commands that plot the vector X = [11 43 127] over time t = [1 2 3]. Make sure that the vector t is on the x axis and the vector X is on the y axis. o Add a title to the figure that says "This is a plot of distance over time" o Add a title to the x axis that says "This is time(s)" o Add a title to the y axis that says "This is distance(m)"
