Analyzing the Discriminant In the Quadratic Formula, the expression ?2 4?? is called the discriminant of the associated equation ??2+ ?? + ?. (Take Note)
A juggler tosses a ball into the air. The ball leaves the jugglers hand 4 feet above the ground and has an initial vertical velocity of 30 feet per second. The juggler catches the ball when it falls back to a height of 3 feet. How long is the ball in the air?
An archer is shooting at targets. The height of the arrow is 5 feet above the ground. Due to safety rules, the archer must aim the arrow parallel to the ground. a. How long does it take for the arrow to hit a target that is 3 feet above the ground? b. b. What method did you use to solve the quadratic equation? Explain
