Answer:
The height of a baseball, in feet, is represented by this expression, where t is time in seconds.
-16t2+64t+3
The height of the baseball after 3.5 seconds is ___ 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](https://tex.z-dn.net/?f=h%3D-16t%5E2%2B64t%2B3)
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)+3h\\\\=-16(12.25)+224+3h\\\\=-196+227h=31](https://tex.z-dn.net/?f=h%3D-16%283.5%29%5E2%2B64%283.5%29%2B3h%5C%5C%5C%5C%3D-16%2812.25%29%2B224%2B3h%5C%5C%5C%5C%3D-196%2B227h%3D31)
Hence, the height of the baseball after 3.5 seconds is 31 feet.
6x - 24 = x - 2
6x - x = -2 + 24
5x = 22
x = 22/5 or 4 2/5 <==
