Amir stands on a balcony and throws a ball to his dog, who is at ground level.The ball's height (in meters above the ground), x seconds after Amir threw it, is modeled by:h(x)=−(x−2)2+16What is the height of the ball at the time it is thrown?□ meters
Q. Amir stands on a balcony and throws a ball to his dog, who is at ground level.The ball's height (in meters above the ground), x seconds after Amir threw it, is modeled by:h(x)=−(x−2)2+16What is the height of the ball at the time it is thrown?□ meters
Identify Time of Throw: Identify the time when the ball is thrown.The time when the ball is thrown is at the beginning of the trajectory, which is at x=0 seconds.
Substitute x=0: Substitute x=0 into the height function to find the height at the time the ball is thrown.h(x)=−(x−2)2+16h(0)=−((0)−2)2+16
Calculate Height: Calculate the height using the given function.h(0)=−(0−2)2+16h(0)=−(−2)2+16h(0)=−(4)+16h(0)=16−4h(0)=12
