An object is launched from a platform. Its height (in meters), x seconds after the launch, is modeled by:h(x)=−5x2+20x+60What is the height of the object at the time of launch?
Q. An object is launched from a platform. Its height (in meters), x seconds after the launch, is modeled by:h(x)=−5x2+20x+60What is the height of the object at the time of launch?
Evaluate height function: To find the height of the object at the time of launch, we need to evaluate the height function h(x) at x=0, which represents the time of launch.Calculation: h(0)=−5(0)2+20(0)+60
Calculate height at launch: Simplifying the expression, we get h(0)=−5(0)+20(0)+60=0+0+60=60 meters.
