Tim throws a stick straight up in the air from the ground. the function h = –16t2 + 48t models the height, h, in feet, of the stick above the ground after t seconds. which inequality can be used to find the interval of time in which the stick reaches a height of more than 8 feet?
a.) –16t2 + 48t > 8
b.) –16t2 + 48t < 8
c.) –16t2 + 48t ³ 8
d.) –16t2 + 48t £ 8

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
