The height y (in feet) of a ball thrown by a child is 1 x² + 6x +3 Y 12 where is the horizontal distance in feet from the point at which the ball is thrown. (a) How high is the ball when it leaves the child's hand? I (b) What is the maximum height of the ball? (c) How far from the child does the ball strike the ground? feet feet feet

can you help me solve for X: root (X) - root (X - 12) = 2

sqrt |x|2 = x

We are standing on the top of a 384 feet tall building and launch a small object upward. The object's vertical position, measured in feet, after t seconds is h(t) — 16t² + 32t + 384. What is the highest = point that the object reaches? feet
