Outcome 1: Solve a problem related to position, velocity, and acceleration. 6. A 25-ft ladder is leaning against a wall. If we push the ladder toward the wall at a rate of 1 ft/sec, and the bottom of the ladder is initially 20 ft away from the wall, how fast does the ladder move up the wall 5 sec after we start pushing? Outcome 2: Set up and solve a related rates problem. 18. The radius of a circle increases at a rate of 2 m/sec. Find the rate at which the area of the circle increases when the radius is 5 m. Outcome 3: Use a linear approximation to estimate the value of a function. 4.2 Practice Score: 1/6 U6 answered 0 Question 6 v Find the linear approximation of x) = 111.12: at m = 1 and use it to estimate ln(l.31). we 1n(1.31) m
