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 t seconds. How many seconds does it take for the ball to reach its maximum height?

t = 1 s

Step-by-step explanation:

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

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

So,

32-32t = 0

t = 1

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

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
