To study how high a ball bounces student drop the ball from various heights. the function h(t)=- 16t^2=h 0 gives the height in feet of ball at the time t measured in seaconds since the ball was dropped from a height of h 0 . if the ball was dropped from a height of 8 feet find the elapsed time until the ball hits the floor

The decibel level of sound is 50 db greater on a busy street than in a quiet room where the intensity of sound is watt/m2. the level of sound in the quiet room is db, and the intensity of sound in the busy street is watt/m2. use the formula , where is the sound level in decibels, i is the intensity of sound, and is the smallest sound intensity that can be heard by the human ear (roughly equal to watts/m2).
