Round 1 Question 1 Find three consecutive numbers whose sum is 156.
Round 1 Question 2 Write an equation to model the situation: The number of cells in a sample quadruples every 24 hours. There were 20 bacteria in the sample initially. Write an equation to find b, the number of bacteria in the sample after d days.
Round 1 Question 3 Twice a number is three less than three times the number. What is the number?
Round 1 Question 4 Use the sequence below: 18, 14, 10, 6 Write an explicit formula for the nth term.
Round 1 Question 5 For a geometric sequence, you are given that a1 = 3 and r = 20. Find a4.
Q1 answer: 51, 52, 53 Q2 answer: b = 20(4d) Q3 answer: 3 Q4 answer: an= -4n + 22 Q5 answer: 24,000 End of Round 1
Round 2 Question 1 What is the slope of a line that is perpendicular to the line that passes through the points (4, 7) and (9, 3)?
Round 2 Question 4 What is the domain of the function graphed at the right?
Round 2 Question 5 Identify the x- and y-intercepts for the graph of 6x + 3y = 18
Round 3 Question 5 This graph shows the growth of a city’s population over time. What does the y-intercept represent in terms of the city’s population?
Round 4 Question 1 Two linear functions are represented below. Which function has the greater rate of change?
Round 4 Question 2 If an = 2an-1 + 3 and a2 = 11, what is a4?
Round 4 Question 3 The graph at the right shows the amount of bacteria, A(t), present over a time period in days, t, where t> 0. What is the approximate rate of change for the function A(t) over the interval [0, 20]?
Round 4 Question 4 Two linear functions are represented below. Compare the rates of change of the functions.
Round 4 Question 5 Is the function represented in the table linear, exponential, or neither?
Final Round Solution D.g(x) = f(x) + 4
