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.

Answer:

Option C - 2(-5)+2(3) ; -4

Step-by-step explanation:

Distributive property means breaking up the factors and multiplying them separately

So here we have 2(-5+3) = 2(-5)+2(3) = (-10)+(6) = (-4)

So (-4) is the value.

Hope this helps you.

Given that angle ABC is congruent to angle DEF and angle GHI is congruent to angle DEF, angle ABC is congruent to angle GHI by the Transitive Property of Equality. The Transitive Property of Equality states that if a = b and b = c, then a = c.
