Answer:
after 11.07secs
Step-by-step explanation:
Given the height of an object modeled by the equation
H = 16T² - 1960
The height of the object on the surface of water is zero, hence H = 0
Substitute
0 =16T² - 1960
Swap
16T² - 1960 = 0
16T² = 1960
T² = 1960/16
T² = 122.5
T = 11.07
Hence the rock will hit the surface of the water after 11.07secs
I may be wrong but my answer is
The slave population is high because of all of the growing crops and they need labor to grow more crops and harvest them. so of course there would be more slaves in those areas, with the most crops. So you can say the slave population in the colonies is high
