- For the following exercises, use this scenario: The equation N(t)=12001+199e0.625t models the number of people in a school who have heard a rumor after t days. To the nearest tenth, how many days will it be before the rumor spreads to half the carrying capacity?arrow_forwardFor the following exercises, solve for the indicated value, and graph the situation showing the solution point. The population of a small town is modeled by the equation P=1650e0.5t where t is measured in years. In approximately how many years will the town's population reach 20,000 ?arrow_forwardFor the following exercises, use this scenario: A turkey is taken out of the oven with an internal temperature of 165° Fahrenheit and is allowed to cool in a 75° F room. After half an hour, the internal temperature of the turkey is 145° F. To the nearest minute, how long will it take the turkey to cool to 110° F?arrow_forward
- For the following exercises, use this scenario: A turkey is taken out of the oven with an internal temperature of 165° Fahrenheit and is allowed to cool in a 75° F room. After half an hour, the internal temperature of the turkey is 145° F. To the nearest degree, what will the temperature be after 50 minutes?arrow_forwardFor the following exercises, solve the application problem. 48.The volume V of an ideal gas varies directly with thetemperature T and inversely with the pressure P.A cylinder contains oxygen at a temperature of310 degrees K and a pressure of 18 atmospheres in avolume of 120 liters. Find the pressure if the volumeis decreased to 100 liters and the temperature isincreased to 320 degrees K.arrow_forwardFor the following exercises, solve for the desired quantity. 59. A musician charges C(x)=64x+20,000 , where x is the total number of attendees at the concert. The venue charges $80 per ticket. After how many people buy tickets does the venue break even, and what is the value of the total tickets sold at that point?arrow_forward
- For the following exercises, use this scenario: A turkey is taken out of the oven with an internal temperature of 165° Fahrenheit and is allowed to cool in a 75° F room. After half an hour, the internal temperature of the turkey is 145° F. Write a formula that models this situation.arrow_forwardUsing Figure 7, solve f(x)=1 .arrow_forwardRefer to the previous exercise. Suppose the lightmeter on a camera indicates an EI of 2 , and thedesired exposure time is 16 seconds. What should thef-stop setting be?arrow_forward
- For the following exercises, use the values listed in Table 1. 29. Solve the equation F(x)=5 .arrow_forwardFor the following exercises, solve for the desired quantity. 56. A stuffed animal business has a total cost of production C=12x+30 and a revenue function R=20x . Find the break-even point.arrow_forwardFor the following exercises, use this scenario: The population P of a koi pond over x months is modeled by the function P(x)=681+16e0.28x . Use the intersect feature to approximate the number of months it will take before the population of the pond reaches half its carrying capacity.arrow_forward
