1:The first time a census was taken in Esinville, the population was 12,621. Each year after that, the population was about 6% higher than it was the previous year.Sketch the graph that represents the situation. Let x represent the number of years since the first census was taken.What are the coordinates of the point that contains the y-intercept?(0, 12,621)(12,621, 0)(1, 12,621)(12,621, 1)2:Doug buys a pint of strawberries every week. The first time he bought them, they cost $2.60. He notices the price is getting more expensive, at a rate of 7% per week.Doug sketches a graph of the situation.Which statements are true?Select each correct answer.The graph decreases from left to right.The point (0, 2.60) is on the graph.The graph has a y-intercept only.The graph has an x-intercept and a y-intercept.The point (2.60, 0) is on the graph.The graph increases from left to right.3:A scientist performed an experiment with a radioactive substance whose half-life is 22 min. The scientist will sketch a graph of the situation, where x represents the time since the scientist first measured the substance, and y represents the amount of radioactive substance remaining at that time.The scientist will only sketch the graph in the quadrant or quadrants for which it makes sense to.In which quadrant or quadrants will the scientist sketch the graph?Quadrants I, II, III, and IVQuadrants I and II onlyQuadrant I onlyQuadrants I and IV only4:The graph represents the atmospheric pressure, in ounces per square centimeter, as a function of altitude in kilometers above sea level.Which statements accurately reflect this relationship?Select each correct answer.The atmospheric pressure gets close to 36 oz/cm2 as the altitude continues to increase.The atmospheric pressure is 0 oz/cm2 at sea level.As the altitude continues to increase, the atmospheric pressure approaches 0 oz/cm2 .As the altitude decreases, the atmospheric pressure increases.5:The graph shows the total monthly sales as a function of the number of cake tiers.Which statement is true?As the number of cake tiers increases without bound, the total monthly sales increase without bound.As the number of cake tiers decreases, the total monthly sales increase without bound.As the number of cake tiers increases without bound, the total monthly sales decrease without bound.There is no limit to the number of cake tiers, but there is a limit to the total monthly sales.
