Answer:
yes.
Explanation:
but what is the question?
The height of the old watch as a function of time can be modeled by the equation
h(t) = –16t^2 + 23t - 8
We set this equation equal to zero because the height the old watch will land outside the hole is zero:
0 = –16t^2 + 23t - 8
Since we have a quadratic equation, we can calculate for t by using the quadratic formula
x = [-b ± sqrt(b^2 - 4ac)] / 2a
t = {-23 ± sqrt[23^2 - 4(-16)(-8)]} / 2(-16)
t = [-23 ± sqrt(17)] / (-32)
t = 0.590 seconds or 0.848 seconds
The two t values show that the old watch will land outside the hole once at 0.590 seconds and again at 0.848 seconds. Therefore, having gone up and back down, it will land at 0.848 seconds.
