A ball is thrown into the air with a speed of 32 feet per second. The function h=32t - 16t^2 models the height of the ball after
beks73 [17]

Answer:

t = 1 s

Step-by-step explanation:

The function models the height of the ball after t seconds is given by :

h=32t - 16t^2

We need to find how many seconds does it take for the ball to reach its maximum height.

For maximum height put dh/dt = 0

\dfrac{dh}{dt}=\dfrac{d}{dt}(32t - 16t^2)\\=32-32t

So,

32-32t = 0

t = 1

So, it will take 1 second to reach its maximum height.

Ede4ka [16]
<h3>Answer: 6 dollars per kilogram</h3>

The unit price is 27/(4.5) = 6 dollars per kilogram

If you wanted, you can think of it like this ratio

4.5 kg : 27 dollars

Dividing both parts of that ratio by 4.5 will lead to

1 kg : 6 dollars
