If an archer shoots an arrow straight upward with an initial velocity of 160
HACTEHA [7]

Answer:

maximum height of the arrow will be 408 m

Step-by-step explanation:

We have given the function of height as h(t)=-16t^2+160t+8

We know that first derivative of height will be velocity

So first derivative of height

\frac{dh}{dt}=-32t+160

v(t)=-32t+160

We know that at maximum height velocity will be zero

-32t+160=0

t = 5 sec

Sp arrow will be at maximum height at t = 5 sec

So height at t = 5 sec will be

h(5)=-16\times 5^2+160\times 5+8=408m

So maximum height of the arrow will be 408 m

Sylvia has a piece of material that is 668.36 square inches. She marked the material into 4 equal pieces and then cut out one of
sveta [45]

The whole magic jug had 668.36 ounces of mysterious elixir in it.
Sylvia came along and marked it into 4 equal amounts, so each
amount was  (1/4)  of  (668.36 ounces).

Now, you would have us believe, she tucked the magic jug under her cloak,
walked quickly and quietly down the hall into the shadows, pulled the jug out,
and quaffed one of the equal amounts from it, all in one slug.

The quantity remaining in the jug was then 

                     (3/4) of (668.36 ounces)  =  501.27 ounces.

The same process works for length, volume, area, stones, money, anything.
If you divide up what you have into 4 equal parts, then each part is 1/4 .
If you eat, sell, lose, or give away  1/4  of it, you have  3/4  left.
