Answer:
Im pretty sure its d hope this helps ;)
We are told that the function f(t) outputs the height at t seconds.
The x-intercept is when y = 0. This is the same as saying when f(t) = 0.
When f(t) = 0, the height is 0, so the x-intercepts represent when the height is 0 and the soccer ball leaves the ground and lands back on the ground.
Answer:
To find the mean, you add all the numbers given (12, 15, 10, and 11) and then divide by the number of values in the set (in this case, 4). This is the same as finding an average. To do this, you add 12 + 15 + 10 + 11 = 48. Since you have 4 numbers, you do 48 ÷ 4, which equals 12. Therefore, the mean is 12.
