In matlab

Find the sum 1.5+3+5+7.5+10 using the sum function and the colon operator.

Using doc function, determine what the dot-asterisk (.*) operator does.

The combined resistance
R_T

of three resistors
R₁, R₂,
and
R₃

in parallel is given by
R_T= 1/(1/R1)+(1/R2)+(1/R3)
Create variables for the three resistors and store values in each, and then calculate the combined resistances
