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.

In a recent survey, 78% of students at Lincoln Middle School said they plan to attend a camp this summer. Write this percent as
prohojiy [21]

Answer:

<em>0.78</em>

Step-by-step explanation:

From the question, we are to represent 78% as a decimal

78%  = 78/100

78/100 = 78 * 1/100

78/100 = 78 * 0.01

78/100 = 0.78

<em>hence the percent written as a decimal is 0.78</em>
