From 1975 to 2009, the age-adjusted incidence rate of invasive lung and bronchial cancer among women can be closely approximated by ƒ(t) = -0.038083t2 + 2.0899t + 24.262, where t is the number of years since 1975. Source: National Cancer Institute. Based on this model, in what year did the incidence rate reach a maximum? On what years was the rate increasing? Decreasing?
Suppose that t years from now, one investment plan will be generating profit at the rate of P1(t)=110+t2 hundred dollars per year, while a second investment will be generating profit at the rate of P2(t)=206+4t hundred dollars per year. Compute the net excess profit assuming that you invest for the time period in which the rate of profitability of the second investment exceeds that of the first.
The following equation represents the number of individuals (N) in a city who contract a highly contagious fatal disease over time(t), what would be the value of the horizontal asymptote? Can you please show full working out.
A company produces chocolate Easter bunnies at a cost per unit of 0.60 + 0.005x dollars, where x is the number produced. If the price on the competitive market for a bunny this size is $5.00, how many should the company produce to maximize its profit?
Suppose that a vending machine service company models its income by assuming that money flows continuously into the machines, with the annual rate of flow given by f(t) = 190e0.08t in thousands of dollars per year. Find the total income from the machines over the first 2 years. (Round your answer to the nearest thousand dollars.)
The population, P, of the city of Hazelton has grown according to the mathematical model P = 65,000(1.075)*, where t is the number of years since 2005. a) At what percentage is the population growing? b) If this trend continues, during which year will the population reach approx. 100,000?
Even though housing prices have been declining in many parts of the country, in Lara's neighborhood, they have been increasing steadily since Lara bought her home in 2006. Lara purchased her home in 2006 for $140,000, and it steadily increased its value by $3400 a year. Let V represent the market value (in dollars) of her home; x, the length of time she has lived there (in years).
The following graph shows the approximate number (in thousands) of people who immigrated to Ireland during the period 2010 through 2014. ( t is time in years since 2010.) (a) During the two-year intervals with the largest magnitude, immigration to Ireland was increasing at an average rate of ____ people per year. (b) During the two-year intervals with the least 92, immigration to Ireland was increasing at an average rate of ____ people per year.
According 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 is continues, the modelP(t)=304⋅(1.011)t−2008P(t)=304⋅(1.011)t-2008represents the population PP (in millions of people) in year tt. According to the model, when will the population be 500 million people? Be sure to round your answer to the nearest whole year.
Hamed own a local gold market that currently has 8549x549 subscriber in Instagram at a quarterly charge of R.O. 18. He notices that if he raises the price of his commodity to R.O. (18 + 4), he will lose 8549 subscriber. Assuming that subscriptions are linearly related to the price, what price should Hamed charge for a quarterly subscription to maximize his revenue?
Suppose that a particular company estimates its growth income from sales by the formula:dS/dt = 2(t − 1)^2/3where S millions of dollars is the gross income from sales t years. If the gross income from the current year’s sales is $8 million, what would be the expected gross income from sales 2 years from now?
About the size of New Jersey, Israel has seen its population soar to more than 6 million since it was established. The given graphs show that by 2050, Palestinians in the West Bank, Gaza Strip, and East Jerusalem will outnumber Israelis. Solve the projected growth of these two populations as given below, a. In 2000, the population of the Palestinians in the West Bank, Gaza Strip, and East Jerusalem was approximately 3.2 million and by 2050 it is projected to grow to 12 million. Use the exponential growth model A = A0ekt, in which t is the number of years after 2000, to find the exponentialgrowth function that models the data. b. In which year will the Palestinian population be 9 million?
