The following expression can be used to evaluate the height of the phone in relation to t time - 16t ^ 2 + 80 What does the 80 represent ? point ) 80 represents how fast the phone is traveling when dropped 80 represents the starting height of the phone when it dropped represents how man seconds takes for the phone to land on the ground 80 represents the time it took for Ms Mac to find her phone below

Answer 1

In the expression \( 16t^2 + 80 \), the \( 80 \) represents the starting height of the phone when it was dropped. It indicates that the phone was initially at a height of 80 units (presumably in feet, if this is a model of a free-falling object) above the ground. Thus, the correct interpretation is:

80 represents the starting height of the phone when it dropped.
