- Computer Virus The number V of computers infected by a virus increases according to the model Vt=100e4.6052t, where t is the time in hours. Find the number of computers infected after (a) 1 hour, (b) 1.5 hours, and (c) 2 hours.arrow_forwardA driver of a car stopped at a gas station to fill up his gas tank. He looked at his watch, and the time read exactly 3:40 p.m. At this time, he started pumping gas into the tank. At exactly 3:44, the tank was full and he noticed that he had pumped 10.7 gallons. What is the average rate of flow of the gasoline into the gas tank?arrow_forwardUse a calculator to help solve each problem. Free-falling objects After t seconds, a certain falling object has a velocity v given by vt=501-e-0.3t. Which is falling faster after 2 seconds, this object or the skydiver in Exercise 38? 38. Sky diving Before the parachute opens, the velocity v in meters per second of a skydiver is given by vt=501-e-0.2t. Find the initial velocity.arrow_forward

Use the model to approximate how many years it will take for the beaver population to reach 78.arrow_forwardIn Example 7, find the average speed of the car (a) from t1=0tot2=1 second and (b) from t1=1 second to t2=4 seconds.arrow_forward
- Sales A company that produces snowboards forecasts monthly sales over the next 2 years to be S=23.1+0.442t+4.3cost6 where S is measured in thousands of units and t is the time in months, with t=1 corresponding to January 2017. Predict the sales for each of the following months. a February 2017 b February 2018 c June 2017 d June 2018arrow_forwardLet f(x)=1x . Find the number b such that the average rate of change off on the interval (2,b) is 110 .arrow_forwardThe number N of bacteria in a refrigerated food is given by NT=8T214T+200,2T12 where T is the temperature of the food in degrees Celsius. When the food is removed from refrigeration, the temperature of the food is given by Tt=2t+2,0t5 where t is the time in hours. a. Find (NT)t. b. Find the time when the bacteria count reaches 1000.arrow_forward
