- A forest fire leaves behind an area of grass burned in an expanding circular pattern. If the radius of the circle of burning grass is increasing with time according to the formula r(t)=2t+1 , express the area burned as a function of time, t (minutes).arrow_forwardMarine Fishery One class of models for population growth rates in marine fisheries assumes that the harvest from fishing is proportional to the population size. For one such model, we have G=0.3n(1n2)0.1n Here G is the growth rate of the population, in millions of tons of fish per year, and n is the population size, in millions of tons of fish. a.Make a graph of G versus n. include values of n up to 1.5 million tons. b.Use functional notation to express the growth rate if the population size is 0.24 million tons, and then calculate that value. c. Calculate G1.42 and explain in practical terms what your answer means. d.At what population size is the growth rate the largest?arrow_forwardGrowth in Length of Haddock D.S. Raitt found that the length L of haddock in centimeters as a function of the age t in years is given approximately by the formula L=5342.820.82t a. Calculate L(4) and explain what it means. b. Compare the average yearly rate of growth in length from age 5 to age 10 years with the average yearly rate of growth from age 15 to age 20 years. Explain in practical terms what this tells you about the way haddock grow. c. What is the longest haddock you would expect to find anywhere?arrow_forward
- The half-life of krypton-91(91Kr) is 10 s. At time t=0 a heavy canister contains 3 g of this radioactive gas. a Find a function m(t)=m02t/h that models the amount of 91Kr remaining in the canister after t seconds. b Find a function m(t)=m0ert that models the amount of 91Kr remaining in the canister after t seconds. c How much 91Kr remains after 1 min? d After how long will the amount of 91Kr remaining be reduced to 1 g 1 microgram, or 106g?arrow_forwardGrowth in Weight and Height Between the ages of 7 and 11 years, the weight w, in pounds, of a certain girl is given by the formula w=8t. Here t represents her age in years. a. Use a formula to express the age t of the girl as a function of her weight w. b. At what age does she attain a weight of 68 pounds? c. The height h, in inches, of this girl during the same period is given by the formula h=1.8t+40. i. Use you answer to part b to determine how tall she is when she weighs 68 pounds. ii. Use a formula to express the height h of the girl as a function of her weight w. iii. Answer the question in part i again, this time using your answer to part ii.arrow_forwardRetirement Savings Ella is saving for her retirement by making regular deposits into a 401(k) plan. As her salary rises, she finds that she can deposit increasing amounts each year. Between 1995 and 2008 the annual amount (in dollars) that she deposited was given by the function. D(t)=3500+15t2 , where t represents the year of the deposit measured from the start of the plan (so 1995 corresponds to t=0 , 1996 corresponds to t=1 , and so on). (a) Find D(0) and D(15) . What do these values represent? (b) Assuming that her deposits continue to be modeled by the function D, in what year will she deposit $17,000? (c) Find the average rate of change of D between t=0 and t=15 . What does this number represent?arrow_forward
