Suppose that at a certain instant the volume is 750 cm and the pressure is 80 kPa and is decreasing at Pa/min. At what rate is the volume increasing at this instant?

MY NOTES ASK YOUR TE A plane flies horizontally at an altitude of 2 km and passes directly over a tracking telescope on the ground. When the angle of elevation is 7/3, this angle is decreasing at a rate of /6 rad/min. How fast is the plane traveling at that time? km/min Need Help? Read It Watch It 18.
