ELECTRICITY The total impedance of a series circuit is the sum of the impedances of all parts of the circuit. A technician determined that the impedance of the first part of a particular circuit was 2 + 5j ohms. The impedance of the remaining part of the circuit was 3 – 2j ohms. What was the total impedance of the circuit?

• 5 + 7j ohms

• 5 + 3j ohms

• -1 + 7j ohms

• 16 + 11j ohms

Which quadratic function has its vertex at (2, 3) and passes through (1, 0)?

• y = 2(x - 2)² + 3

• y = -3(x - 2)² + 3

• y = -3(x + 2)² + 3

• y = 2(x - 2)² - 3
