10. An airplane flying 390 feet per second at an altitude of 5000 feet flew directly over an observer. The image shows the relationship of the airplane to the observer at a later time. a.) Find an equation relating x and y. 5000t 390 ce Б000 b.) Find the value of x when y is 6,250. Observer c.) How fast is the distance from the observer to the airplane changing at the time when the airplane is = 390 and y = 6,250? dt dx 6,250 feet from the observer? That is, what is dy at the time when dt

Find the distance between the following two points: (0, -2) and (-5, -1) O 26 O VI

NAME 12. Find the slope and the y-intercept of y =-x-5 a) Slope: y-intercept: (0,5 4: y-intercept (0.-5) b) Slope: --; inte o:-intercept: (0.-5) d) Slope: -2; y intercept: (0,-5)

4) The position of an time in seconds the object has been in motion. How long (to the nearest tenth) will it take the object to = 2t2- 3t, where s is in meters and t is the object moving in a straight line is given by s move 14 meters? 302
