- Does the equation y=2.294e0.654t representcontinuous growth, continuous decay, or neither?Explain.arrow_forwardSuppose that a machine's production can be considered as a continuous income stream with annual rate of flow at time t given by f(t) = 10,000 − 900t (dollars per year). If money is worth 10%, compounded continuously, find the present value of the machine over the next 8 years.arrow_forwardAccording to the U.S. Census Bureau, the population of the United States in 2008 was 304 million people. In addition, the population of the United States was growing at a rate of 1.1% per year. Assuming this growth rate continues, the model t- 2008 P(t) = 304 · (1.011)' represents the population P (in millions of people) in year t. According to the model, when will the population be 442 million people? Be sure to round your answer to the nearest whole year. Yeararrow_forward
- Suppose f ( t ) = 120 ( 1.035 ) t models the population of a city (in thousands) t years from now. This model predicts the population of the city will increase. True or False?arrow_forwardThis exercise uses the radioactive decay model. The half-life of cesium-137 is 30 years. Suppose we have a 14-g sample. (a) Find a function m()- me2h that models the mass remaining after t years mt) - 14(2)) (b) Find a function m(t) = me that models the mass remaining after t years. (Round your rvalue to four decimal places.) m(t) = (c) How much of the sample will remain after 79 years? (Round your answer to one decimal place.) (d) After how many years will only 2g of the sample remain? (Round your answer to the nearest whole number.) yrarrow_forwardSuppose that a business provides a continuous income stream with an annual rate of flow at time t given by f(t) = 120e0.05t in thousands of dollars per year. If the interest rate is 10% compounded continuously, find the capital value of the business.arrow_forward
