Please feel free to use the graph of the equation or test algebraically to determine whether the following equation is an odd function, an even function, a function that is neither odd nor even, or a function that is both odd and even. 19. The weight M of an object on the moon varies directly as its weight E on earth. A person weighs 169.76 lbs on earth weighs 28.86 lbs on the moon. How much would a 241.76-lb person weigh on the moon? 20. The stopping distance d of a car after the brakes have been applied varies directly as the square of the speed r. If a car traveling 60 mph can stop in 200 ft, how fast can a car travel and will stop in 72 ft? d ÃŽ ± r2 or d= kr2 for a speed of 60 mph , the distance is 200ft. therefore, 200= k (60)2 k= 200/3600 = 0.0556 ; Hence d= 0.0556r2 . For a car to stop at 72 ft; 72= 0.0556r2 ; r2= 72/0.0556 = 1294.96 hence r = 35.9856 mph or approximately 36
