Explanation Use the initial values in the logistic equation to determine the value of the constant and then use that to find the number of days it will take for the fish to reach 900. Given: A lake has a carrying capacity of 1000 fish. Assume that the fish population grows logistically with growth constant k = 0.2 d a y − 1 . Calculation: Let y ( t ) represent the population of fish. Using the form of a logistic equation we have y ( t ) = 1000 1 − e − 0.2 t / C Given y ( 0 ) = 20 So, y ( 0 ) = 1000 1 − 1 / C = 20

8:39 *** TEMU 5G 60% A ferris wheel is 28 meters in diameter and boarded from a platform that is 2 meters above the ground. The six o'clock position on the ferris wheel is level with the loading platform. The wheel completes 1 full revolution in 4 minutes. The function h = f(t) gives your height in meters above the ground t minutes after the wheel begins to turn. What is the amplitude? 14 meters What is the equation of the Midline? y = 16 What is the period? 4 meters minutes The equation that models the height of the ferris wheel after t minutes is: f(t): = ƒ (3) = ·−14(0) + 16 syntax error: you gave an equation, not an expression. syntax error.
