Sketch the situation if necessary and use related rates to solve. A 6 ft tall person walks away from a 10 ft lamppost at a constant rate of 5 ft/s. What is the rate (in ft/s) that the tip of the shadow moves away from the pole when the person is 15 ft away from the pole? 10 ft F ft/s ·15 ft 6 ft What is the rate (in ft/s) at which the tip of the shadow moves away from the person when the person is 15 ft from the pole? O Draw and label a diagram to help solve the related-rates problem. } The side of a cube increases at a rate of m/s. Find the rate (in m³/s) at which the volume of the cube increases when the side of the cube is 8 m. 6 A conical tank has height 3 m and radius 2 m at the top. Water flows in at a rate of 1.9 m³/min. How fast is the water level rising when it is 1.1 m from the bottom of the tank? (Round your answer to three decimal places.)
