Answer 2

Answer:

The height of the baseball after 3.5 seconds is 31 feet.

Step-by-step explanation:

Consider the provided expression.

The height of a baseball, in feet, is represented by this expression, where t is time in seconds.

$h=-16t^2+64t+3$

To find the height of the baseball  after 3.5 seconds, substitute the value of t = 3.5 in above expression

$h=-16(3.5)^2+64(3.5)+3$

$h=-16(12.25)+224+3$

$h=-196+227$

$h=31$

Hence, the height of the baseball after 3.5 seconds is 31 feet.
