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.

Answer:

A: $-w^{2}+6w+17$

B: $5w^{2}+14w+7$

Step-by-step explanation:

We have been given that the area of Jocelyn's village is represented by the polynomial $2w^{2}+10w+12$ . The area of Lorlesha's village is represented by the polynomial $3w^{2}+4w-5$ , where w represents the width, in meters of their Town hall.

A: To find the expression that will represent the additional area of Jocelyn's village, we will subtract the total area of Lorlesha's village from the total area of Jocelyn's village.

$\text{Additional area of Jocelyn's village}=2w^{2}+10w+12-(3w^{2}+4w-5)$
