MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The Admiralty Coefficient A is a nautical value that relates a ship's (top) speed S, horsepower H, and displacement D. The relationship is A = D Here speed is measured in knots and displacement is measured in tons. For Victory Ships produced in World War II, the Admiralty Coefficient was about 422. Their engines produced 6000 horsepower, and they had a displacement of 14,800 tons. What was the speed of a typical Victory Ship? (Round your answer to two decimal places.) X knots 4.

MY NOTES ASK YOUR TEACHER When a skydiver jumps from an airplane, her downward velocity, in feet per second, before she opens her parachute is given by the ormula below, where t is the number of seconds that have elapsed since she jumped from the airplane. The terminal velocity skydiver is 182 feet per second. v = 182(1 - 0.8345) How long does it take for her to reach 90% of the terminal velocity? (Round your answer to two decimal places.) 6.

MY NOTES ASK YOUR TEACHER In a study of a marine tubeworm, scientists developed a model for the time 7 (measured in years) required for the tubeworm to reach a length of L meters. On the basis of their model, they estimate that 170 to 250 years are required for the organism to reach a length of 2 meters, making this tubeworm the longest-lived noncolonial marine invertebrate known. The model is given below. = 20ebl - 28 Here b is a positive constant that requires estimation. What is the value of b if an estimate of 175 years to reach a length of 2 meters is correct? (Round your answer to two decimal places.) = What is the value of b if an estimate of 235 years to reach a length of 2 meters is correct? (Round your answer to two decimal places.) b = 7.

MY NOTES ASK YOUR TEACHER The following exercise poses a question that can be answered by solving an equation. Give the appropriate equation. Note that you are not asked to solve the equation. An investment grows according to the formula B = 400e0.05t dollars, where t is time, measured in years. The time required for the balance to reach $1200 is the solution of an equation. Find that equation
