The following MATLAB statements plot the function $y(x)=4e^{-0\mathrm{.}3x}$ for the range $0x10.$

$x=0$:$0\mathrm{.}1$:$10$;

$y=4**exp(-0\mathrm{.}3**x)$;

plot$(x,y)$;

Use the MATLAB Edit$/$Debug Window to create a new empty script, type these statements into the script, and save the file with the name test $1.m.$ Then, execute the program by typing the name test $1$ in the Command Window or clicking the "Run" button. What result do you get?

Calculate the results of the following expressions in a new file.

$($a$)(\frac{1}{5^2}+\frac{3}{2}-1{)}^{-3}$

$($b$)2-{}^{0\mathrm{.}5}$

$($c$)1+\frac{1}{2}+\frac{1}{2^2}+\frac{1}{3^3}+\frac{1}{2^4}$

Suppose that $u=1$ and $v=3.$ Evaluate the following expressions in a new file.

$($a$)\frac{4u}{3v}$

$($b$)\frac{2v^{-2}}{(u+v{)}^2}$

$($c$)\frac{v^3}{v^3-u^3}$

$($d$)\frac{4}{3}{v}^2$
