- Population Statistics The table shows the life expectancies of a child (at birth) in the United States for selected years from 1940 through 2010. A model for the life expectancy during this period is y=63.6+0.97t1+0.01t,0r70 Where y represents the life expectancy and t is the time in years, with t=0 corresponding to 1940. (a) Use a graphing utility to graph the data from the table and the model in the same viewing window. How well does the model fit the data? Explain (b) Determine the life expectancy in 1990 both graphically and algebraically. (c) Use the graph to determine the year when life expectancy was approximately 70.1. Verify your answer algebraically. (d) Identify the y-intercept of the graph of the model. What does it represent in the context of the problem? (e) Do you think this model can be used to predict the life expectancy of a child 50 years from now? Explainarrow_forwardDraw a scatter plot for the data in Table 2. Then determine whether the data appears to belinearly related.arrow_forwardBiology The metabolic rate of an ectothermic organism increases with increasing temperature within a certain range. Experimental data for the oxygen consumption C (in microliters per gram per hour) of a beetle at certain temperatures can be approximated by the model C=0.45x21.65x+50.75,10x25 where x is the air temperature in degrees Celsius. a The oxygen consumption is 150 microliters per gram per hour. What is the air temperature ? b When the air temperature increases from 10C to 20C, the oxygen consumption increases by approximately what factor ?arrow_forward
- Does the following table represent a linear function ? If so, find the linear equation that models the data.arrow_forwardProjectile Motion In Exercises 75 and 76, consider the path of an object projected horizontally with a velocity of v feet per second at a height of s feet, where the model for the path is x2=v216ys. In this model (in which air resistance is disregarded), y is the height (in feet) of the projectile and x is the horizontal distance (in feet) the projectile travels. A ball is thrown from the top of a 100-foot tower with a velocity of 28 feet per second. (a) Write an equation for the parabolic path. (b) How far does the ball travel horizontally before it strikes the ground?arrow_forwardLyme Disease The numbers Nof confirmed cases of Lyme disease in Maryland from 2007 through 2014 are shown in the table, where t represents the year, with t=7corresponding to 2007. (a) Use a graphing utility to create a scatter plot of the data. (b) Use the regression feature of the graphing utility to find a quartic model for the data. (A quartic model has the form at4+bt3+ct2+dt+e,where a,b,c,d,and e are constant and t is variable.) Graph the model in the same viewing window as the scatter plot. (c) Use the model to create a table of estimated values of N.Compare the model with the original data. (d) Use synthetic division to confirm algebraically your estimated value for the year 2014.arrow_forward

Let x represent the year, with x=8 corresponding to 2008. (b) Use the linear regression capabilities of a graphing utility to find a linear model for the data. How does this model compare with the model obtained in part a? (c) Use the linear model to create a table of estimated values for y. Compare the estimated values with the actual data.arrow_forwardFurther Verification of Newtons Second LawThis exercise represents a hypothetical implementation of the experiment suggested in the solution of part 6 of Example 3.7. A mass of 15 kilograms was subjected to varying accelerations, and the resulting force was measured. In the following table, acceleration is in meters per second per second, and force is in newton. Acceleration Force 8 120 11 165 14 210 17 255 20 300 a. Construct a table of differences and explain how it shows that these data are linear. b. Find a linear model for the data. c. Explain in practical terms what the slope of this linear model is. d.

Explain how this experiment provides further evidence for Newtons second law of motion.arrow_forwardTEST FOR UNDERSTANDING FOR EXAMPLE 5.16 In the study Economics of Scale in High School Operation by J. Riew, the author studied data from the early 1960s on expenditures for high schools ranging from 150 to 2400 enrollment.
