Reciprocal of combined resistance R of two resistance R1 and R2 connected in parallel is equal to sum of reciprocals of individual resistances. If two resistances are connected in series, their combined resistance is sum of their individual resistances. If two resistances connected in parallel have the combined resistance of 15.0 ohms and same two resistance have the combined resistance of 64 ohms when connected in series, determine resistances? Write intructions of the function in words
F(z)= 4z / 5-z
