Final answer:
The height of the baseball 4 seconds after being hit is calculated using the equation h = 16t^2 + 80t + 3. Plugging in t = 4 seconds, the height is found to be 579 feet, which does not match any of the provided options. There may be a typo in the question or the options given.
Step-by-step explanation:
To find the height of the ball 4 seconds after it is hit, we use the given equation h = 16t^2 + 80t + 3. Substituting t = 4 seconds into the equation gives us:
h = 16(4)^2 + 80(4) + 3
h = 16(16) + 320 + 3
h = 256 + 320 + 3
h = 579 feet
Therefore, the height of the ball after 4 seconds is 579 feet. However, this answer is not included among the provided options (a) 331 feet, (b) 403 feet, (c) 475 feet, (d) 547 feet. The question may contain a typo in the equation, or in the given options, as none of the choices match the calculated result.
