The amount of carbon dioxide emissions (in teragrams = 1012 grams) from human activities in the U.S. can be approximated by myopenmath.com f(x) = -21.5t2 + 242.8t + 5424.4 According to recent data from the Teachers Insurance and Annuity Association (TIAA), the survival function for where t is the number of years since 2000. life after 65 is approximated by S(x) = 1 - 0.058x - 0.076x2 (a) What are the units of the parameter 21.5? where a is measured in decades. S() gives the probability that an individual who reaches the age of 65 will live at least a decades (10x years) longer. Note that probabilities are decimal numbers between 0 and 1 that O teragrams do not have units associated with them. O teragrams/year O teragrams^2/year (a) What are the units of the parameter 0.058? O year 2/teragrams O 1/year O teragrams/year^2 O probability/decade O probability/year (b) What are the units of the parameter 242.8? O 1/decade O 1/decade^2 Oyears O teragrams (b) What are the units of the parameter 0.076? O teragrams/year O teragrams/year^2 O probability/year^2 year/teragrams O decade/year O 1/year^2 O 1/decade ^2 c) What are the units of the parameter 5424.4? probability/decade^2 O teragrams/year O teragrams O years Submit Question O teragrams/year^2 wear/teraorams A car is driving at 95 kilometers per hour. How far, in meters, does it travel in 4 seconds? (a) Which conversion equations do you need to use to convert km/h into m/s? Write them into the window. Edit * Insert Formats B I U X X A Y Av (b) What is the conversion equation from km/h to m/s? Give your answer as a fraction in reduced (most simplified) form. km 1 - m h (c) How far (in meters) does the car travel in 4 seconds? Give your answer to the nearest meter. (Hint: Use units to help you check the formula you use to compute the distance.) PIC . COLLAGE meters
