The cheerleaders at a football game launched t-shirts into the crowd from the back of a golf cart that is 2 ft off the ground the t-shirts have an upward velocity of 30 ft per second using the function y equals negative 16 t squared plus 30t + 2 which of the following correctly identifies the y intercepts and best explains its meaning

1 answer

To analyze the provided function \( y = -16t^2 + 30t + 2 \), we will first identify its y-intercepts by setting \( t = 0 \), because the y-intercept occurs where the function crosses the y-axis (i.e., when \( t = 0 \)):

\[ y(0) = -16(0)^2 + 30(0) + 2 = 2 \]

This shows that the y-intercept is at the point \( (0, 2) \).

Meaning of the Y-Intercept:

The y-intercept represents the initial height of the t-shirts at the moment they are launched. In this case, when \( t = 0 \) (the time of launch), the height \( y \) of the t-shirts is 2 feet. This indicates that the t-shirts are being launched from a height of 2 feet above the ground (the height of the golf cart).

In summary:

  • The y-intercept is \( (0, 2) \).
  • Its meaning is that the t-shirts are launched from a height of 2 feet above the ground.
