- Temperature An object at a temperature of 80C is placed in a room at 20C . The temperature of the object is given by T=20+60e0.06m where m represents the number of minutes after the object is placed in the room. How long does it take the object to reach a temperature of 70C ?arrow_forwardLIFE SCIENCE APPLICATIONS Life Span Researchers have estimated the maximum life span in years for various species of mammals according to the formula L(E,P)=23E0.6P0.267, where E is the average brain mass and P is the average body mass both in g. Source: The Quarterly Review of Biology. Find L for the following species. Do these values seem reasonable? a. Black rat, with E=7.35g, P=150g b. Humans, with E=14,100g, P=68,700g c. d.arrow_forwardFilling a Tank The water level in a tank rises 4feet every minute. Write an equation of change that describes the height H, in feet, of the water level at time t in minutes.arrow_forward
- Medical Drugs When a certain medical drug is administered to a patient, the number of milligrams remaining in the patients bloodstream after t hours is modeled by D(t)=50e0.2t How many milligrams of the drug remain in the patients bloodstream after 3 hours?arrow_forwardChemical Dissolution The amount of chemical that will dissolve in a solution increases exponentially as the temperature is increased. At 0C, 10 g of chemical dissolves, and at 10C, 11 g dissolves. Write an equation to express the amount of chemical dissolved, y, in terms of temperature, t, in degree Celsius. At what temperature will 15 g dissolve?arrow_forwardSuppose gas costs 3.50 a gallon. We make a model for the cost C of buying x gallons of gas by writing the formula C=.arrow_forward
