hours. Given the equation, you can plug in your time to solve for after 1 hour. You can then use the doubling formula to solve for , by taking the natural log of both sides. 35. (a) is the top graph is the bottom graph (b) 0.977507% (c) (d) 20 torrs: 62.8%, 40 torrs: 20.6%, 60 torrs: 7.1% You can evaluate which graph is which by plugging in values for in each equation, and figuring out which graph is which. By plugging in 100 for , you can solve for the level of oxygen saturation. You want to evaluate each equation at to compare the level of hemoglobin. By following the definition of efficiency of oxygen, you want to evaluate both equations at , and then subtract from 37. (a) (b) or days To find a formula, you can use the information that when , and . Using this information you can take the natural log of both sides to solve for Once you’ve solved for , you can come up with a k. general equation. For (b), you know , where you can substitute your known radius in for . You can use this information to solve for . Once you’ve done this, you can set the equation , and take the natural log of both sides to solve for. 39. Since the number of termites and spiders are growing exponentially, we can model them as and , respectively. We know the population when you move in (when ) is 100. Then , so . We also are given that there are 200 termites after 4 days, so . Then our model is . We can then use this formula to find and . Then and . Then: Since represents the initial population of spiders, which should be a whole number, we’ll round to 76, so our model is . To find when it triples, let . Then days.
