Mr. Smith launched a rocket that he made with his science students from ground level with an initial velocity of 128 feet
per second. The height of the rocket h after t seconds is given
by the equation:
h(t) = -16t2 + 128t
Determine how long it will take for Mr. Smith's rocket to return
to the ground.
seconds

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
