The chart to the right shows a country's annual egg production. Model the data in the chart with a linear function, using the points (0,51.7) and (4,60.2). Let x = 0 represent 1995, x = 1 represent 1996, and so on, and let y represent the egg production (in billions). Predict egg production in 2001. How does the result compare to the actual data given in the table, 69.5? Year Egg production (in billions) 51.7 52.5 54.3 57 60.2 63.8 69.5 1995 1996 1997 1998 1999 2000 2001 The linear model for the data is (Type an equation using x as the variable. Type your answer in slope-intercept form. Use integers or decimals for any numbers in the equation. Round to the nearest thousandth as needed.)
A college math placement test has 50 questions. The score is computed by awarding 4 points for each correct answer and subtracting 2 points for each incorrect answer. Determine the linear function that would be used to compute the score. Use the function to determine the score when a student gets 35 questions correct.

The thickness of ice y in the Gladstone Glacier was 450 feet in 1990. By 2005, the thickness had shrunk to 400 feet. Let x be the elapsed number of years since 1990. Write a linear function that models this data. Then use the function to find the given value. (Simplify your answer and round to TWO decimal places, including zeros as needed. Example: 2 should be written as 2.00. Do not include commas.) Estimate the year when the Gladstone Glacier will be 350 feet thick. (Round your answer to TWO decimal places, including zeros as needed. Example: 2 should be written as 2.00. Do not include commas.)
Some pedometers have a default setting that assumes that the number of steps a person must take to walk 1 mile decreases by 32 steps per 1 inch increase in height. Suppose a person 72 inches tall makes 2,250 steps per mile. Find a linear model of the number of steps S per mile as a function of height h (in inches). S = Use the model to predict the number of steps per mile a person who is 64 inches tall will take. steps per mile
Suppose that the number of tee shirts sold (N) depends linearly on the price charged (x). Write an equation showing this dependence.
A variable star is one whose brightness alternately increases and decreases. For the variable star Delta Cephei, the time between periods of maximum brightness is 5 days. The average brightness ( or magnitude) of the star is 4 and its brightness varies by ±0.35 magnitude. Suppose the brightness of the star can be modeled by the equation y =acosbt + d. a. What is the value of b? b. Find a function that models the brightness of Delta Cephei as a function of time.
