Your answer is B, my good friend. And increase in the number of other grazing animals
Other important factors that are to be considered in addition to averages in precipitation and temperature in regards to describing climate would be its air humidity, cloudiness, speed of the wind and its direction, as well as the air pressure present.
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.
