The cheerleaders at a football game launch T-shirts into the crowd from the back of a golf cart that is 2 feet off the ground. The T-shirts have an upward velocity of 30 feet per second. Using the function y=−16t^2+30t+2 , which of the following correctly identifies the y-intercept and best explains its meaning?(1 point) Responses The y-intercept is at (0,2) . The shirt will reach the ground after 2 seconds from being launched. The y -intercept is at left parenthesis 0 comma 2 right parenthesis . The shirt will reach the ground after 2 seconds from being launched. The y-intercept is at (0,0) . The shirts are launched from the ground. The y -intercept is at left parenthesis 0 comma 0 right parenthesis . The shirts are launched from the ground. The y-intercept is at (0,2) . The shirts are launched at an initial height of 2 feet. The y -intercept is at left parenthesis 0 comma 2 right parenthesis . The shirts are launched at an initial height of 2 feet. The y-intercept is at (2,0) . The shirts are launched at an initial height of 2 feet.
The correct answer is:
The y-intercept is at (0,2). The shirts are launched at an initial height of 2 feet.
This is because the y-intercept represents the starting point of the function when t = 0, and in this case, it is at (0,2), indicating that the shirts are launched from an initial height of 2 feet.
