- Finding mass transit fares The Municipal Transit Authority serves 150,000 commuters daily when the fare is 1.80. Market research has determined that every penny decrease in the fare will result in 1000 new riders. What fare will maximize revenue?arrow_forwardPopulation Growth There are originally 255 foxes and 104 rabbits on a particular game reserve. The fox population grows at a rate of 33 foxes per year, and the rabbits increase at a rate of 53 rabbits per year. Under these conditions, how long does it take for the number of rabbits to catch up with the number of foxes? How many of each animal will be present at that time?arrow_forwardPopulation Growth These exercises use the population growth model. 8. Bacteria Culture It is observed that a certain bacteria culturehas a relative growth rate or 12% hour. but in the presence of an antibiotic the relative growth rate is reduced to 5% per Hour.initialnumber of bacteria in the culture is 22. Population,n after 24 hours for following conditions. (a) No antibiotic is present, so the relative rate is 12%.

- Financial Planning Mark has $100,000 to invest. His Financial consultant advises him to diversify his investment in three types of bonds: short-term, Intermediate-term, and long-term. The short-term bonds pay 4%, the intermediate term bonds pay 5%, and the long-term bonds pay 6% simple interest per year. Mark wishes to realize a total annual income of 5.1 % with equal amounts invested in short - and intermediate-term bonds. How much should he invest in each type of bond?arrow_forwardNutrition A researcher performs an experiment to test a hypothesis is that involves the nutrients niacin and retinol. She feeds one group of laboratory rats daily of diet of precisely 32units of niacin and 22,000units of retinol. She uses two types of commercial foods.

- Nutrition A biologist is performing an experiment on the effects of various combinations of vitamins. She wishes to feed each of her laboratory rabbits a diet that contains exactly 9mg of niacin, 14mg of thiamin, and 32mg of riboflavin. She has available three different types of commercial rabbit pellets; their vitamin content per ounce is given in the table.

A mass of 15 kilograms was subjected to varying accelerations, and the resulting force was measured. In the following table, acceleration is in meters per second per second, and force is in newton. Acceleration Force 8 120 11 165 14 210 17 255 20 300 a. Construct a table of differences and explain how it shows that these data are linear. b. Find a linear model for the data. c. Explain in practical terms what the slope of this linear model is. d. Express, using functional notation, the force resulting from an acceleration of 15 meters per second per second, and then calculate that value. e. Explain how this experiment provides further evidence for Newtons second law of motion.arrow_forward
