Unformatted text preview: 4) It has been found that the less income people have, the more likely they are to report that their health is fair or poor. The function f(x) = -4.4 x + 38 models the percentage of Americans reporting fair or poor health, f(x), in terms of annual income, x, in thousands of dollars. According to the model, what annual income corresponds to 10% reporting fair or poor health? Round to the nearest thousand dollars. 5) Complex numbers are used in electronics to describe the current in an electric circuit. Ohm's law ( E=IR ) relates the current, I , in amperes, the voltage, E, in volts and the resistance, R , in Ohms. Find the voltage when the current is (4-5i) amperes and the resistance is (3+7i) Ohms. 1...
