Unformatted text preview: MAC 1105 Module Test 2 Name___________________________________ MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. You are given a table showing input and output values for a given function y 1 = f(x). Use the table to answer the question. 1) What is the x- intercept of the graph of y = f(x)? A)- 2 B) 6 C)- 1 D) 0 Answer: B Objective: (1.5) Tech: Find Intercepts of Function Given Table Solve the formula for the speciFed variable. 2) I = nE nr + R for n A) n = IR Ir + E B) n = - R Ir- E C) n = IR(Ir- E) D) n = - IR Ir- E Answer: D Objective: (1.5) Solve Formula for Specied Variable A linear function y 1 has been graphed in an appropriate viewing window. Use the x- intercept method to solve the equation y 1 = 0. 3) A) 4 B) 5 C) 2 D) 0 Answer: A Objective: (1.5) Tech: Solve Linear Eqn Using x- Intercept Method 1 Solve the formula for the speciFed variable. 4) P = a + b + c for a A) a = P- b- c B) a = b + P- c C) a = b + c- P D) a = P + b + c Answer: A Objective: (1.5) Solve Formula for Specied Variable Solve the problem. 5) The temperature of water in a certain lake on a day in October can be determined by using the model y = 15.2- 0.537x where x is the number of feet down from the surface of the lake and y is the Celsius temperature of the water at that depth. Based on this model, how deep in the lake is the water 11 degrees? (Round to the nearest foot.) A) 64 ft B) 49 ft C) 26 ft D) 8 ft Answer: D Objective: (1.5) Solve Apps: Linear Equations Solve the equation. 6) (y- 9)- (y + 6) = 8y A)- 15 8 B)- 5 3 C)- 15 7 D)- 1 4 Answer: A Objective: (1.5) Solve Linear Equation Algebraically Solve the formula for the speciFed variable. 7) A = P(1 + nr) for r A) r = P- A Pn B) r = Pn A- P C) r = A n D) r = A- P Pn Answer: D Objective: (1.5) Solve Formula for Specied Variable Solve the equation....
