Answer 1

Answer:

The initial height of the arrow is 1.5 feet above the ground.

Step-by-step explanation:

Let be the height of the arrow be represented by the function $h(t) = -16\cdot t^{2}+128\cdot t + 1.5$, where $h(t)$ is the current height of the arrow, measured in feet, and $t$, is the time, measured in seconds.

Mathematically speaking, the initial height is the value of $h$ evaluated at $t = 0\,s$. That is:

$h(0) = -16\cdot (0)^{2}+128\cdot (0) + 1.5$

$h(0) = 1.5\,ft$

The initial height of the arrow is 1.5 feet above the ground.
