Number 6 shown above, please and thank you!

whle user-defined & function that calculates Req. For the function name and arguments use REQ req (R). The input to function should be a vector in which each element is a resistor value, and the output from the function is Reg. Use the function to calculate the equivalent resistance when the following resistors are connected in parallel: sn, 150, 120, 7, 50, and 75 6- The friction factor for incompressible flow through a smooth pipe is given below. The friction factor is used to calculate the pressure drop in a pipe. a. Write a MATLAB code that calculates the friction factor, f, given the Reynolds number (Re) using 'IF' statements. Re A s 2100 f(Re) = 16/Re (Re) -0.0791/Re f (Re) - 0.004 2100
