1. If the complex number x = 3 + bi and |x| = 13, which is a possible value of b? 4 9 10 2. What is the sum of -2 and -18? 4.52 4i2 3. If f(x) = 1 - x, which value is equivalent to |f(i)|? 0 -1 4. Which property of addition is shown in the equation below? a + bi + 0 + 0i = a + bi Commutative property Inverse property Identity property Associative property 5. Melissa and Tomas are playing a game with complex numbers. If Melissa has a score of 5 - 4i and Tomas has a score of 3 + 2i, what is their total score? 8 - 6i 8 + 6i 8 - 2i 8 + 2i 6. Which property of addition is shown below? a + bi + c + di = a + c + bi + di Identity property Associative property Commutative property Inverse property 7. Which property of multiplication is shown below? If x = a + bi and y = c + di, x y = y x. Commutative property Identity property Distributive property Associative property 8. Donte simplified the expression 4(1 + 3i) - (8 - 5i) as 4 + 3i - 8 + 5i = -4 + 8i. What mistake did Donte make? He did not apply the distributive property correctly for 4(1 + 3i). He did not distribute the subtraction sign correctly for 8 - 5i. He added the real number and coefficient of i in 4(1 + 3i). He added the two complex numbers instead of subtracted. 9. Evaluate (2 - 5i)(p + q)(i) when p = 2 and q = 5i. 29i 29i - 20 -21i 29 10. The relationship between voltage, E, current, I, and resistance, Z, is given by the equation E = IZ. If a circuit has a current I = 3 + 2i and a resistance Z = 2 - i, what is the voltage of the circuit?
