A football is kicked from the ground and travels at a rate of 10 meters per second. The function 𝑓(𝑥)=10𝑥−5𝑥2 represents the ball's height above the ground at x seconds. Based on this function model, what is the football's highest point and how long will...

Suppose a ball was dropped from a TV tower 2120 feet high. The time it takes an object to free-fall from the top of this tower to the ground can be represented by the equation s = −16t2 + 2120, where s is the distance from the ground in feet and t is the...
