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.
[tex]h=-16t^2+64t+3[/tex]
To find the height of the baseball after 3.5 seconds, substitute the value of t = 3.5 in above expression
[tex]h=-16(3.5)^2+64(3.5)+3[/tex]
[tex]h=-16(12.25)+224+3[/tex]
[tex]h=-196+227[/tex]
[tex]h=31[/tex]
Hence, the height of the baseball after 3.5 seconds is 31 feet.
