Please write fully in matlab code:

Use the variable names highlighted in the instructions below. Each variable should be in it's own column in the resulting solution array.

a$)$ Create an array representing a table of conversions from feet to meters $.$ Start the feet column at $0,$ increment by $1$ and end it at $10$ ft$.$ Name your solution array xa$.$

$1$ meter $=3\mathrm{.}28$ feet

b$)$ Create an array representing a table of conversions from radians to degrees. Start the radians column at $0$ and increment by $0\mathrm{.}1$ radians, up to radians. Name your solution array xb$.$

degrees $=$ radians$*180/$

c$)$ Create an array representing a table of conversions from miles per hour $($mph$)$ to feet per second $($fps$).$ Start the mph column at $0$ and end it at $100$ mph$.$ Include $15$ values in your table. Name your solution array xc$.$ Use the linspace function to create your mph array.

fps $=$ mph$*5280/3600$

d$)$ The acidity of solutions is generally measured in terms of pH$.$ The pH of a solution is defined as of the concentration of hydronium ions. Create an array representing a table of conversions from concentrations of hydronium ions to pH$,$ spaced logarithmically from $0\mathrm{.}001$ to $0\mathrm{.}1$ mol$/$liter with $10$ values. Use H$\_$conc as the variable name for the concentration of hydronium ions. This means the equation for pH will be:

pH $=-$log$10($H$\_$conc$)$

Name your solution array xd$.$
