Rate of descent Parachutes. At low altitudes, the altitude of a parachutist and time in the air are linearly related. A jump at 2,880 ft using the U.S. Army’s T-10 parachute system lasts 120 secs.
Find a linear model relating altitude
Find the rate of descent for a T-10 system.
(C) Find the speed of the parachutist at landing.

- The time required to empty a pool varies inversely as the rate of pumping. It took Lucy 2.5 hours to empty her pool using a pump that was rated at 400 gpm (gallons per minute). a. Write the equation of variation. b. How long will it take her to empty the pool using a pump rated at 500 gpm?arrow_forwardThe force needed to break a board varies inversely with its length. Richard uses 24 pounds of pressure to break a 2-foot long board. a. Write the equation of variation. b. How many pounds of pressure is needed to break a 5-foot long board?arrow_forwardDoes Table 2 represent a linear function? If so, finda linear equation that models the data.arrow_forward
- In 2004, a school population was 1,001. By 2008the population had grown to 1,697. Assume thepopulation is changing linearly. a. How much did the population grow between theyear 2004 and 2008? b. How long did it take the population to grow from1,001 students to 1,697 students? c. What is the average population growth per year? d. What was the population in the year 2000? e. Find an equation for the population, P, of theschool t years after 2001. f. Using your equation, predict the population of theschool in 2011 .arrow_forwardIf you travel 100 miles in two hours, then your average speed for the trip is Average speed=_________=________arrow_forwardThe length a spring stretches varies directly with a weight placed at the end of the spring. When Meredith placed a 6-pound cantaloupe on a hanging scale, the spring stretched 2 inches. How far would the spring stretch if the cantaloupe weighed 9 pounds?arrow_forward
- What is interpolation when using a linear model?arrow_forwardThe resistance of a copper wire carrying an electrical current is directly proportional to its length and inversely proportional to its cross-sectional area. A copper wire with a diameter of 0.0126inch has a resistance of 64.9ohms per thousand feet. What length of 0.0201-inch-diameter copper wire will produce a resistance of 33.5ohms?arrow_forwardLinear models can be used to predict buying habits of consumers. Suppose that a survey found that in 2008, 18% of the consumers surveyed in a group bought designer frames for their eyeglasses. In 2011, the percentage climbed to 24 % a. Assume the percentage of people buying frames is a linear function of time, and find an equation for the percentage of people buying designer frames. Let t correspond to the number of years since 2008 P(t) b. Use your equation to predict the percentage of people buying designer frames in 2014 The model predicts the percentage of people buying designer frames in 2014 will be | c. Use your equation to predict when the percentage of people who buy designer frames will reach 50 % The model predicts in the year 1, 50% of people will buy designer frames d. Do you think you can use this model to predict the percentage of people buying designer frames in the year 2051? Why or why not?arrow_forward
