- Target heart rate The target heart rate f(x), in beats per minute, at which a person should train to get an effective workout is a function of the persons age x in years. If f(x)=0.6x+132, find the target heart rate for a 45-year-old college professor.arrow_forwardWebsite Growth The number y of hits a new website receives each month can be modeled by y=4080ekt, where t represents the number of months the website has been operating. In the website’s third month, there were 10,000 hits. Find the value of k, and use this value to predict the number of hits the website will receive after 24 months.arrow_forwardFill in the blanks.

- Use a calculator to help solve each problem. Life expetctancy The life expectancy l of white females can be estimated by using the function lx=78.51.001x, where x is the current age. Find the life expectancy of a white female who is currently 50 years old. Give the answer to the nearest tenth.arrow_forwardMathematically show that f(x) = 3x³ – x is an odd function. %3Darrow_forward6miles 1. 2-0.86 5miles O 4miles 3miles 2miles 1miles Omin 1min 2min 3min 4min 5min Train z = 5.84 X = 5 Terminal Cell Tower 3 miles return this question to its initial state A train is headed south at 1 mile/min towards the terminal while a cell tower stands three miles east of the terminal. The bottom window in the applet above shows the position of the train, terminal, and cell tower. The variable x is the distance from the train to the terminal. The variable z is the distance from the train to the cell tower.arrow_forward

- DEPRECIATION The value of a new tractor decreases by 30% each year. The initial cost of a tractor is $35,000. Write a functionf(t) that can be used to project the value of the tractor t years in the future. = s 2 (0)arrow_forwardPlot the Function x+earrow_forwardQuestionSheet The amount of garbage, G, produced by a city with population p is given by G = f (p). G is measured in tons per week, and p is measured in thousands of people. a. The town of Tola has a population of 50,000 and produces 10 tons of garbage each week. Express this information in terms of the function f. Enter your answer as an equation. Do not enter an any units (people, tons) or commas in your answer. Include a multiplication sign between symbols if you need to. For example, enter a az. b. Explain the meaning of the statement f (7) = 3. The amount of garbage produced per week by a city with population 3,000 is 7 tons. The amount of earbage produced per week by a city with Dopulation 3 is 7 tons.
