Hey, I have this hw question that's really confusing me, any help would be appreciated. An object is fired upwards with an initial velocity of 112 feet per second. It's bright, in feet above the ground, as a function of time, in seconds since it was fired, is given by the equations h(t) = -16t^2 + 112t (A) At what height was the object fired. (B( Algebraically, find the time that the rocket reaches its greatest height and the maximum height (C) Algebraically, determine the time when the rocket reaches the ground Thanks a million!!

Ascientist studied a population of workers to determine whether verbal praise and/or tangible rewards affect employee productivity. in the study, some workers were offered verbal praise, some were offered tangible rewards (gift cards, presents, and some were offered neither. the productivity of each participant was measured throughout the study by recording the number of daily tasks completed by each employee. which inference might the scientists make based on the given information? a.) the number of daily tasks completed by each employee may influence the dependent variable, which is whether the employee receives verbal praise, tangible rewards, or neither. b.) verbal praise and/or tangible rewards may influence the independent variable, which is the number of daily tasks completed by each employee. c.) verbal praise and/or tangible rewards may influence the dependent variable, which is the number of daily tasks completed by each employee. d.) the dependent variables, which are verbal praise and tangible rewards, may influence the number of daily tasks completed by each employee.
