Solve the following questions using MATLAB. Problem$1$: Create a variable a that is a row vector with the following elements: $9,1,3-,7/4,0,2\mathrm{.}25$x $8\mathrm{.}5,0\mathrm{.}8,$ and sin$(\backslash$pi $/8).$ Problem $2$: Define the variables c $4\mathrm{.}5$ and d$-2\mathrm{.}8,$ and then use them to create a co umn vector $($assign it to a variable named $)$ that has the following elements: d$,$ e$,($e$+$d$,,$ and d$.$ Problem $3$: Create a variable d that is a column vector with the following elements: $0\mathrm{.}75+5\mathrm{.}207,1\mathrm{.}1,$V$60,$ tan$(10\backslash$pi $/11),$ cos$-5\backslash$deg $,$ and $0\mathrm{.}116.$ Problem $4$: Create a variable N that is a column vector with seven equally spaced ele$-$ ments in which the first element is $44$ and the last element is $23.($A column vector can be created by the transpose of a row vector.$)$ Problem $5$: Use a single command to create a row vector $($assign i to a variable named with nine elements such that the last four elements are $8\mathrm{.}1$ and the rest of the elements are $0$s$.$ Do not type the vector elements explicitly.
