Answer:
The correct option is;
D. -8·t² + 18·t + 6 = 10
Step-by-step explanation:
The given equation of the height toy cannon launched on top of a platform is given as follows;
h(t) = -8·t² + 18·t + 6...(1)
Where "h" represents the height in meters, at time "t" seconds after the ball is launched
When the height is 10 meters, we can write as follows;
The height of the ball, h(t) = 10
Therefore, by substituting the value of h(t) in equation (1), h(t) = -8·t² + 18·t + 6, when h(t) = 10 we get;
-8·t² + 18·t + 6 = 10.
