Due to gravity, an object falls 16t^2 feet in t seconds. You drop a backpack from a window that is 20 feet above the ground. Wil
sukhopar [10]

Answer:

NO

Step-by-step explanation:

Let h(t) represent the distance the pack is located above the ground at time t.  Then h(t) = 20 ft - 16t^2 ft.  Notice how h = 20 ft (the initial height) and that it decreases as t increases.

How long does it take for the pack tohit the ground?  Set h(t) = 0 and solve for t:

0 ft = 20 ft - 16t^2 ft yields 16t^2 ft = 20, or t^2 ft = 20/16, which is greater than 1.  So the question "Will the backpack hit the ground in 1 second" is answered by NO.

Number of amusement parks and arcades in 2004 = 3344

Decrease in the number of amusement parks from 2004 to 2009 = 148

So, the expression to calculate the total number of amusement parks and arcades in 2009 is 3344 - 148

Evaluating the expression we get the total number of amusement parks and arcades in 2009 as 3196

Hope that help!
