An object is propelled vertically upward from the top of a 256-foot building. The quadratic function s(t) = -16t squared + 1
92t + 256 models the ball's height above the ground, s(t), in feet, t seconds after it was thrown. How many seconds does it take until the object finally hits the ground? Round to the nearest tenth of a second if necessary. A. 6 seconds
Step-by-step explanation: We know that, every 20 shots he attempts, he makes 18. He has a 90% success rate. If he attempts 100 free throws, he would make 90% of them, which is 90!
Another way to solve it is note that 100 is 20*5, so 18*5 is 90, which is also our answer.
