A baseball is hit off of a tee from a height of 3 meters with an initial vertical component of velocity of 18 meters per second. The height of the ball is modeled using the quadratic function h(t)=−16t2+18t+3is the height, in meters, of the baseball and t is the time the ball has been in the air, in seconds. a) Write an equation that could be used to determine the time the ball traveled before it hit the ground

answer: the answer is ann

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
