A student is speeding down Route 11 in his fancy red Porsche when his radar system warns him of an obstacle 400 feet ahead. He immediately applies the brakes, starts to slow down, and spots a skunk in the road directly ahead of him. The "black box" in the Porsche records the car's speed every two seconds, producing the following table. The speed decreases throughout the 10 seconds it takes to stop, although not necessarily at a uniform rate.

The diagram below illustrates the number of moose (red curve) and wolves (blue curve) between 1960 and 2015 in the Isle Royale National Park (USA). It does not show the actual data, but it approximates the trend. The vertical scale is from 0 to 50 for wolves and 0 to 2500 for moose. In certain years the moose population was decreasing and the wolf population was increasing. Which of the options below represents such a year? A. 1980   B. 1970   C. 2000   D. 2010

A baseball team plays in a stadium that holds 58000 spectators. With the ticket price at $11 the average attendence has been 26000. When the price dropped to $9, the average attendence rose to 29000. Assume that attendence is linearly related to ticket price. What ticket price would maximize revenue? $

In a certain country, total alcoholic beverage sales are reported throughout the year. Sales were reported as $118.5 billion at the beginning of 2004 and $136.2 billion at the beginning of 2006. (a) Let the x-axis denote time and the y-axis denote the amount of alcohol sales (in billions), Let x = 0 correspond to 2004. Fill in the blanks: The given data is represented by the points ( 118.5) and (2, ). (b) Find the linear equation determined by the two points in part (a). (c) Use the equation in part (b) to estimate the alcohol sales produced in 2005. (d) If the model remains accurate, in what year will reported alcohol sales reach $150 billion? (a) The given data is represented by the points (,118.5) and (2,). (Type integers decimals rounded to one decimal place.) (b) The linear equation determined by the two points in part (a) is y =x+. (Type integers or decimals rounded to one decimal place.) (c) The alcohol sales produced in 2005 are approximately $ billion. (Type an integer or…
