Returning to Exercise 23, explain why it is reasonable for the graph representing the falling crate to be shaped as it was. How does this conform to your intuition? Would a linear equation have been an acceptable model?
23. Falling bodies. A plane is dropping emergency food supplies to relieve famine in a less-developed country. Crates are dropped, and the height of the crate above the ground at time t is given by the equation
a. Graph this equation.
b. Are there any values for t that it would not make sense to use for this equation because of the physical characteristics of a falling crate?
c. Find the time at which the crate will strike the ground.

- The number y (in thousands) of male participants in high school lacrosse in the United States from 2008 through 2015 can be approximated by the linear model y=3.66t+91.4,2t5 where t represents the year, with t=0 corresponding to 2010. (a) Find algebraically and interpret the y-intercept of the graph of the linear model. (b) Use the linear model to predict the year in which there will be 128,000 male participants.arrow_forwardCholesterol.

- Neurology The average weight of a male child’s brain is 970 grams at age 1 and 1270 grams at age 3. (a) Assuming that the relationship between brain weight y and age t is linear, write a linear model for the data. (b) What is the slope and what does it tell you about brain weight? (c) Use your model to estimate the average brain weight at age 2. (d) Use your school’s library, the Internet, or some other reference source to find the actual average brain weight at age 2. How close was your estimate? (e) (d) Do you think your model could be used to determine the average brain weight of an adult?
