Question

Type the correct answer in the box. Use numerals instead of words.

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.

Answer 1

The height of the baseball after 3.5 seconds can be found by substituting t = 3.5 into the equation -16t² + 64t + 3, resulting in a height of 31 feet.

Step-by-step explanation:

The height of the baseball after 3.5 seconds is calculated by substituting t = 3.5 into the given quadratic expression -16t² + 64t + 3. Performing the substitution gives us:

• -16(3.5)² + 64(3.5) + 3
• -196 + 224 + 3
• 28 + 3
• 31 feet

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