An object is thrown into the air. The equation for the object's height s at timet seconds after launch is H(C) = -4.912 + 13.4t + 24.9, where H is in meters.

Part A: What does the coefficient for the quadratic term representa

Part B: What does the coefficient for the linear term represent?

Part C: What does the constant term represent?

Given: abcd is a square. prove: ac ? bd. we are given that abcd is a square. if we consider triangle aeb and triangle aed, we see that side is congruent to side ad because sides of a square are congruent. we know that side ae is congruent to side ae by using the . finally, we know that side de is congruent to side because the diagonals of a square bisect each other. therefore, triangle aeb is congruent to triangle aed by congruency. we see that angle aed and angle aeb are a linear pair, and congruent by cpctc. thus, the measure of these angles will be 90°, and diagonal ac is perpendicular to diagonal bd by the .
